[NTG-context] Extend the fraction bar
All,
How can I extend the main fraction bar in the following expression,
making it a tad longer?
\placeformula
\startformula
\dfrac{\dfrac{9+3x-2x^2}{x^2-16}}{\dfrac{4x^3-9x}{2x^2+5x-12}}.

All,
Came across this again.
\placeformula[-]
\startformula
[9,\infty)=\{x:\,x\ge 9\}

Got it to compile with:
\placeformula[-]
\startformula\relax
[9,\infty)=\{x:\,x\ge 9\}

Yuk!

This message is a bit misleading. Knuth means to say:

... and that is precisely what happens when you try to use
\eqno in a formula that is numbered automatically already.

Taco,
Thanks for that explanation. I would not have found out by myself
that this error is not about being in math mode, but about being in a
numbered equation.
I am inclined to stick to this as a bug. Not of ConTeXt, of course,
but of TeX's error reporting system. It would be nice if someone in
the pdfetex community took it as a challenge to make this error item
more to the point.

Something strange occurs in math, doing:

Why cannot \eqno be used in math mode? It is its raison d'etre!
Plain TeX typesets the following input without problems:
$$ a = b + c\eqno{(12)} $$
\end
Strange enough the following does work as expected:
\placeformula\startformula
\eqalignno{
H(K|M,C) = H(K|C) - H(M|C)\eqno{\hbox{(\in{}[eq:keyapp])}}\cr

Is this a little bug perhaps?

[NTG-context] More Feature Requests for math
Hi Hans,
Can you provide some more features to \definematrix and
\definemathcases.
1. Allow \definematrix and \definemathcases to have a parameter
displaystyle or textstyle. Right now, everything is in textstyle.
Consider
\startformula
a = \startcases
\NC E = mc^2 \NC nothing interesting to see here \NR
\NC \int_0^1 x - 3 d\,x \NC Integral is in text mode \NR
\stopcases
\stopformula
\startformula
\startmatrix[n=2]
\NC x \NC y \NR
\NC \int_0^1 x - 3 d\,x \NC 20 \NR
\stopmatrix
\stopformula
Both integrals are in textstyle. It will be nice if one had a
configuration like
\definemathcases[displaycases][displaystyle]
and \definemathmatrix[displaymatrix][displaystyle]
so that
\startdisplaymatrix
\NC a \NC b \NR
\NC d \NC e \NR
\stopdisplaymatrix
is equivalent to
\startmatrix
\NC \displaystyle a \NC \displaystyle b \NR
\NC \displaystyle d \NC \displaystyle e \NR
\stopmatrix
and similar for startdisplaycases.
I don't know which syntax is better displaystyle=on|off (yes|no) or
[mathstyle=display|text].
2. Allow location=top|center|bottom for \definemathmatrix. Right now,
inside \dostartmathmatrix there is a \vcenter. Can this be changed to
\vtop or \vbottom depending on the value of location.
With these features, it will be straightforward to emulate the
behaviour of aligned and gathered environments of amsmath.
3. Can pagebreak inside \startalign be restored. This used to work,
but broke while ensuring compatibility with \setupformulas[align=??]
\placeformula \startformula \startalign
\dorecurse{50}
{ \NC a \EQ b \NR[+] }
\stopalign \stopformula
Thanks,
Aditya

[NTG-context] Breaking large equations across pages
Pagebreak of formula across pagebreaks is broken in the new release
(ConTeXt ver: 2006.04.27 15:59).
Consider
\starttext
\placeformula \startformula \startalign
\dorecurse{50}
{\NC a \NC = b \NR[+]}
\stopalign \stopformula
\stoptext
(This used to work earlier, I can not test this, but I have document
where the display broke across pages. Can somewith with an old ~ Mar,
2006 release test this?)
Also, is it possible to have more control over where the display
breaks. With latex, I can force equation break by using
\allowdisplaybreaks[1|2|3|4]
\documentclass{article}
\usepackage{amsmath}
\allowdisplaybreaks % Try with and without this.
\begin{document}
\begin{align}
a = b \\
% Paste the above line 50 times
a = b
\end{align}
\end{document}
Ideally, context should also provide something configurable. Maybe, it
should be part of
\setupformulas[displaybreak=tolerant|verytolerant|strict|verystrict]
Also there should be something like
\NC \NR
\allowdisplaybreak[yes|no|disable...same meaning as in \page[]
\NC . \NR
to have more control over the pagebreak.

I wrote the following emacs lisp for my .emacs and pass it on (no

with the old tex mode, but just rewrote it for auctex and for context's
display math syntax (which deprecates $$...$$).
The purpose:
1. If you type {, [, or (, the appropriate right delimiter is inserted
for you and the insertion point is placed between them. So I never
get unbalanced XYZ errors. If you think it's a misfeature, delete
the last three local-set-key's in the TeX-mode-hook.
2. Same feature if you type $ for inline math: you get $insertion point

so you'd get $$insertion point here$$ for tex's display math.

Hi Aditya,
I tested your solution and it works great. I cannot see any problems
in my output. I wish I had your Tex programming skills, I am trying
to learn the language myself from the TexBook (D.Knuth) but I still
have a long way to go.
Well, I do not understand Tex. What I usually do is look at the
context source, which is much easier to read than latex internals, and
then copy from there, play around a bit, and sometimes things
work.
Another test to check that the formula numbers work as expected
\placeformula[kem-chapter-eqn11]
\startformula
\cases{
\eqalign{
\widehat{\vec{x}} = - \vec{x} \cr
\widehat{t} = t \cr
}}
\quad \text{resp.} \quad
\cases{\eqalign{
\widehat{\vec{x}} = \vec{x} \cr
\widehat{t} = -t \cr
}}
\stopformula
How about
\definemathmatrix
[group]
[left={\left\{\,},right={\right.}]
\startformula
\startgroup
\NC \widehat{\vec{x}} \NC= - \vec x \NR
\NC \widehat t\NC= t\NR
\stopgroup
\quad \text{resp} \quad
\startgroup
\NC \widehat{\vec{x}} \NC= \vec x \NR
\NC \widehat t\NC= -t \NR
\stopgroup
\stopformula
There is also startstop cases, but that does not give the correct
spacing in this case. May be useful otherwise.
\startformula
\startcases
\NC \widehat{\vec{x}} \MC= - \vec x \NR
\NC \widehat t\MC= t\NR
\stopcases
% Read MC as Math Column, there is also the usual NC
% which gives a text column
\quad \text{resp} \quad
\startcases
\NC \widehat{\vec{x}} \MC= \vec x \NR
\NC \widehat t\MC= -t \NR

Sometimes one wants to have two columns of equations, next to one another.
This can be done by specifying the number of blocks in \typem=?.
\starttyping
\startformula \startalign[m=2]
\NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR
\stopalign \stopformula
\stoptyping
\startformula \startalign[m=2]
\NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR
\stopalign \stopformula
The distance between the blocks can be increased by specifying (well you
guessed it) \typedistance in the parameters of align.
\starttyping
\startformula \startalign[m=2,distance=5em]
\NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR
\stopalign \stopformula
\stoptyping
\startformula \startalign[m=2,distance=5em]
\NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR
\stopalign \stopformula
However, this block mode can be cumbersome to work with. You need to work with
two formulas at the same time and this can be confusing. There is another
alternative in \tex{startformulas}

\section{Equation Numbering and referring}
To number multiline displays, two things need to be done. Write
\tex{placeformula} before \tex{startformula} to {\em start up} equation
numbering. To actually number the equations, you need to type \type{[+]} with
each \tex{NR}. Going back to our basic example
\starttyping
\placeformula
\startformula \startalign
\NC a_1 x + b_1 y \NC = c_1 \NR[+]
\NC a_2 x + b_2 y \NC = c_2 \NR[+]
\stopalign \stopformula
\stoptyping
\placeformula
\startformula \startalign
\NC a_1 x + b_1 y \NC = c_1 \NR[+]
\NC a_2 x + b_2 y \NC = c_2 \NR[+]
\stopalign \stopformula
If you only want to number a some specific equations, just add \type[+] to
that equation only. Suppose in the above example, we want to only number the
second equation.
\starttyping
\placeformula
\startformula \startalign
\NC a_1 x + b_1 y \NC = c_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NR[+]
\stopalign \stopformula
\stoptyping
\placeformula
\startformula \startalign
\NC a_1 x + b_1 y \NC = c_1 \NR
\NC a_2 x + b_2 y \NC = c_2 \NR[+]

When I compile your code, it works. However my code , which I think,

I cannot see any difference in the setup. I must be doing something
basically wrong ???
Here is an excerpt from my code
\def\mathrm#1{ {\rm #1}}
\def\done#1#2{ \frac{ \mathrm{d} #1}{\mathrm{d} \mathrm{#2}} }

I do not want to do this: \setupformulas[indentnext=auto] or this: \setupformulas[indentnext=yes] Because that has the effect that paragraphs following formulae are always indented. I don't want that. I want to be able to type the source like this ... \setupwhitespace[medium] \setupindenting[medium,yes] \starttext Again, we choose to multiply the fours, then the result by the square root of three. That is, \placeformula[-] \startformula 4(4\sqrt3) =16\sqrt3. \stopformula By induction, we can argue that that the associative and commutative properties will allows us to group and arrange the product of more than three numbers in any order that we please. \stoptext ... and not have the next paragraph after the formula. That is the default. That is what I want. However, on occasion, sometimes I do want to indent the next paragraph after a formula. My question is, how to override the default behavior on occasion. That is, every rare once in a while, how do I indent a paragraph after a formula. On Feb 20, 2006, at 10:13 AM, Taco Hoekwater wrote: David Arnold wrote: OK, But this gives the same result.

Re: [NTG-context] Force an indent
[someone else beat me to the punch.] (\indentation instead of \indent) That's not the most obvious choice of command name, but it works, eh?. To protect yourself, you could add more logical markup and say something like this in your environment: \let\NewPar\indentation and then mark all paragraphs to be indented with that \NewPar. adam On Feb 20, 2006, at 10:13 AM, Taco Hoekwater wrote: David Arnold wrote: OK, But this gives the same result.

[NTG-context] math tests - subformula ref's and symbols \oiint \oiiint like in Latex AMS
Title: math tests - subformula ref's and symbols \oiint \oiiint like in Latex AMS
Hi,
I am using Context for the second time now and I am investigating
the pro's and con's before migrating my Latex documents to Context.
So far I am really impressed with Context capabilities.
Now I am testing some of the math I typeset with Latex to
determine whether or not to use Context.
In Latex I am using the ams math packages and knowing that there is
a amsl module for Context I did some test such as
\def\wdiv{{\rm div} \:}
\def\rot{{\rm rot} \:}
\placeformula[eqn1]
\startformula
\eqalignno{
\wdiv \vec{E} = \frac{\rho}{\epsilon_{0}} \formulanumber{.a} \cr
\rot \vec{B} = \mu_{0} \:\vec{j} \subformulanumber{.b} \cr
\wdiv \vec{B} = 0 \subformulanumber{.c} \cr
\rot \vec{E} + \frac{\partial \vec{B} }{\partial t} = 0 \subformulanumber{.d} \cr}
\stopformula
How can I refer to these subformulas in my running text ?
As I am typesetting a lot of math in my physics doc's I use a lot of integration symbols amongs others.
In Latex I use \oint, \oiint and \oiint, even a quadruple int to indicate space - time integrals. Even I defined
a tex command for the surface integral.
I also found the Context \showmathcharacters which gave me most of the math symbols from the amsl module.
However I did not found alternatives for \oiint, \oiiint unfortenately.
I discovered the \definemathsymbol in several context tex files, I was wondering if it is possible to
setup my own \oiint, \oiiint, \ont ... symbols ? If yes, my problem is I can't find any docu's on the usage of \definemathsymbol ?
Any help appreciated
Kind regards
W.Neimeijer

[NTG-context] Typesetting chemical reaction equations
I would need to typeset some rather simple reaction equations. I do not need the structural capabilities of PPCHTeX, just something simpler. The thing I am writing has something to do with physical chemistry, so I need mathematical equations, as well. Of course, the natural way to do this: \placeformula \startformula \rm NH_3(g) + H^+(aq.) + Cl^-(aq.) \rightarrow NH_4^+(aq.) + Cl^-(aq.) \stopformula This gives rather pleasant-looking results. However, is this the right (i.e. kosher) way of doing things, or do I run into trouble at some later point with this? What are you chemists using? And how do I switch off the equation numbering for the chemical reactions (I'd like to have the mathematical formulae still numbered)?

Re: [NTG-context] Typesetting chemical reaction equations
And how do I switch off the equation numbering for the chemical reactions (I'd like to have the mathematical formulae still numbered)? Stupid me. Just by leaving the \placeformula out. (Maybe I should go and get something to eat, my brain seems to be in some sort of energy-saving mode.) By the way, is there a simple way to have two separate numbering schemes?

[NTG-context] setupindenting and formula
Hi all,
I use \setupindenting[medium,yes] in my document.
When I use:
\placeformula[GiPivel]
\startformula
\frac{\overrightarrow{G_iP_i}}{\Delta T} = \frac{d_i.\vec{y_i} +
\delta_i.\vec{t_i}}{\Delta T} = -\dot{\theta_i}.\vec{z_i} \wedge
l_i.\vec{x_i}+ V_i.\vec{x_i} = -\dot{\theta_i} l_i.\vec{y_i}+
V_i.\vec{x_i}
\stopformula
Test sentence to check indenting.
The test sentence is not indented...
Consequently, I have tried:
\indent
Test sentence to
check indenting.
Unfortunately, the test
sentence isn't indented...
To indent or not to indent, that is the question !!! ;-)

If I understand you correctly, then something like this
\definealign[cases][left={\left\{}, right={\right.}, n=2,
align={left,left}]
will give us \startcases, \stopcases which works like \cases. Such a
feature will be very useful.
Is it possible to define left|right in such a way that
\definealign[important][left={\framed\bgroup},right={\egroup}]
results in a frame around the equations (and does not include the equation
numbers), that is the frame is as broad as the width of the largest
equation that follows. This mechanism can be used to highlight equations.
Also, in another post, I had asked if it is possible to have cases that
are numbered, that is, can I get
{ b , if whatever (1a)
a ={
{ c, otherwise (1b)
This is not important, but will be nice to have.

Not exactly. In this, I get two formula numbers, one for the case
`x=7' and the other for the entire equation. I can remove
\placeformula and almost get the desired behaviour. There should be an
option to flushright the equation number corresponding to each case,
i.e., I should be able to get
+-+
| |
| ,- |
| | 15, if something (1) |
| x = { |
| | 0, otherwise (2) |
| `- |
+-+
Where the frame is the page boundaries. I hope I am making sense here.
Further, I can not get correct subnumbering here. Look at the output
of
\startformula \startcases
\NC a \NC if something \NR[eq:a][a]
\NC b \NC otherwise\NR[eq:b][b]
\stopcases \stopformula
Other than these minor glitches, this is perfect.

[NTG-context] formula in itemlist
I want to place a math formula in the item of an itemlist, but I keep getting overfull hboxes. A minimal example follows: \starttext \startitemize \item dit is een \item dit is een formule \placeformula[-] \startformula n= 0% this is line 7 \stopformula \stopitemize \stoptext in the log it says: Overfull \hbox (17.62474pt too wide) in paragraph at lines 7--7 [][] \hbox(10.41603+4.05064)x0.0 .\glue(\leftskip) 17.62474 .\hbox(0.0+0.0)x0.0 .\hbox(10.41603+4.05064)x0.0 ..\rule(10.41603+4.05064)x0.0 ..\glue 0.0 plus 1.0fil minus 1.0fil .\penalty 1 .\glue(\parfillskip) 0.0 plus 1.0fil .etc. Removing the \placeformula makes no difference. Although a fallback to $$ n = 0 $$ makes the overfull hbox go away, it does not seem the ConTeXt way of doing.

I'd like to get two of these side-by-side, or something that will
typeset a similar result side-by-side.
Thanks.

Re: [NTG-context] math align
Hans, Taco, et al,
If I do something like this:
\placeformula[-]
\startformula
\startalign[m=2,distance=7em]
\frac5{21}-\frac3{21}=\frac{5-3}{21}
\frac{2}{x+2}-\frac{x-3}{x+2}=\frac{2-(x-3)}{x+2}\\
=\frac2{21} =\frac{2-x+3}{x+2}\\
=\frac{5-x}{x+2}
\stopalign
\stopformula
Note that distance=7em separates the equations nicely, at least for
the layout within which this code is contained. It might not look as
good if the layout changes.
I'm wondering if the current math-ext allows these to be evenly
distributed across the page without adjusting the distance?

=\frac{5-x}{x+2}
\stopalign
\stopformula
Note that distance=7em separates the equations nicely, at least for
the layout within which this code is contained. It might not look as
good if the layout changes.
I'm wondering if the current math-ext allows these to be evenly
distributed across the page without adjusting the distance?
\startalign[m=2,distance=7em plus 1 fil]
is a start but i assume that you want it more centered

The following works as expected.

\def\stopsplit
{\doalignNR[+][]\crcr % for a number on last line

It seems that you are still thinking about [#2] in the definition of
\definealign. Can it be such that,
\definealign[gather][n=1,align={middle}]
\definealign[lgather][n=1,align={left}]
\startformula \startgather
a = b + c \\
e = f
\stopgather \stopformula
results in center aligned equations
a = b + c
e = f
and
\startformula \startlgather
a = b + c \\
e = f
\stoplgather \stopformula
results in left aligned equations
a = b + c
e = f

(n=n_of_columns, m=n_of_pairs, so both requested multiple column features are

Thanks a lot. I tested it with the little context math documents that
I have and it works as expected. There is a minor bug. I thought that
... \\ and \NC .. \NC .. \NR were equivalent, with the latter giving
more configurability with respect to equation numbering and all.
However, with multiple columns, \NC ... \NC does not work as expected.
Consider
\usemodule[math-ext]
\starttext
Three columns work correctly if I use \
\startbuffer
\startformula \startalign[n=3]
a = b = c \\
d = e = f
\stopalign \stopformula
\stopbuffer
\typebuffer \getbuffer
But they do not work if I use \type{\NC}
\startbuffer
\startformula \startalign[n=3]
\NC a \NC= b \NC= c \NR
\NC d \NC= e \NC= f \NR
\stopalign \stopformula
\stopbuffer
\typebuffer \getbuffer
\stoptext
This takes care of most of the alignment and equation numbering in
Context. With this, one should also be able to define \startstop split
such that
\placeformula \startformula \startsplit
a = b \\
= c
\stopsplit \stopformula
comes out as
a = b
= c (1)
But, my attempts to define such a startstop did not work. Can you
suggest something?
Thanks,
Aditya

Compare this from how to do this in context (see the wiki). You have to
*manually* set the number of the subequation. Actually, for equation
numbering and refering, the context way is rather limited. Consider
something like an align environment
a = b\\
c = d\\
e = f
Suppose, I want to refer to the second equation. In latex, I can simply
add \label{eq:2} and the end of c= d and then \ref{eq:2}. For context,
the reference label goes at the top, with \placeformula[eqs]. But I am not
sure, how to give individual labels to each equations.
this 'loose label' is one of the ugliest concept i can think of -)
If you come up with any other way, I will be glad to use it. Frankly, I do
not think that the latex syntax is the best, but plain tex looks too
indimidating and context does not have anything yet.
btw, defaulting to numbers and then using \notag is messy; i prefer
readable code, even if it takes more bytes; inventing a formula takes
more time than keying it in. Also, more structure, means more hooks for
configurability
Fine by me. Your method is perfectly acceptable.
much if this 'complicated' math is not that complicated to support,see
attached file
Wonderful. I did not know that something like this can be done so easily in
context.
i'm willing to implement anything reasonable but since i hardly use such
math i only act on 'i want to achieve this' kind of specs (i have no time
to read tons of tex documents)
Here are features that I would want context math to have. I do not care about
the input syntax (whether it is same as latex or not) as long as the features
are there.
[snipped]
One more request. Allow these align, gather environments to break
across a page. Allow the user some kind of customization, whether the
break can occur at a particular location or not.

If you come up with any other way, I will be glad to use it. Frankly,
I do not think that the latex syntax is the best, but plain tex looks
too indimidating and context does not have anything yet.

Fine by me. Your method is perfectly acceptable.
much if this 'complicated' math is not that complicated to support,see
attached file
Wonderful. I did not know that something like this can be done so
easily in context.
i'm willing to implement anything reasonable but since i hardly use such
math i only act on 'i want to achieve this' kind of specs (i have no time to
read tons of tex documents)
Here are features that I would want context math to have. I do not
care about the input syntax (whether it is same as latex or not) as
long as the features are there.
1. Have align support with variable number of columns.
a = b
= c + d
+ e
should be typeset as
a = b
= c + d
+ e
2. Have a mechanism to individually number/not-number an equation.
3. Have a gather environment. Depending on the user option should
either center, left justify or right justify all equations. Useful
when you have a bunch of equation together and do not want to have
startforumla and stopformula after each of them.
4. In align you should be able to specify the separation between
columns. There should be some input syntax that allows you to typeset
an output like
a = b c = d
e = f g = h
It will be great if you can number each equation (i.e. four number in
the above example). There should be an option to only number each
line.
5. have a splitformula environment that allows
a = b
+ c \\
+ d
to come out as
a = b
+ c
+ e(1)
with only one formula number. The formula number should be at the last
line or the center of the whole formula, configurable by an option.
6. Allow, someway of typesetting
a = b + c
Using some result
= d + e
that is, you should be able to come out of the align mode temporarily
and then go back. Latex calls this intertext. Have some means to
adjust the before and after skips of intertext. Something like
\setupintertextskip[small or medium or big]
7. Allow some way of typesetting multilined formula where
first line is left aligned
second line after some hskip
third line after some hskip
...
last line right alinged
This should have only one formula number, either on the last line or
in the center of the display.
8. Have a version of align, gather and multiline that can be used
inside a formula. So one should be able to type
\startformula
\left.\startaligned
\NC a \NC= b \NR
\NC c \NC= d \NR
\stopaligned\right\}
\implies
\startaligned
\NC b \NC= a \NR
\NC d \NC= c \NR
\stopaligned
\stopformula
to get
a = b } = b = a
c = d } d = c
where the implies is centered between the two lined.
Have an option to make these environments come at the top, middle or
bottom of the baseline.
9. Allow easy input of multiline subscripts. Suppose I want
\sum
a b
c d
e f
10. Allow the big subscripts of math operators to be smashed to the
left or right. Suppse, I have
a \times \lim_{a very long equation} b_n
There should be a command, say \smashoperator such that
a \times \smashoperator\lim_{a very long equation} b_n
comes as
a lim b_n
a very long eq
where (a very long equation) in centered beneath the center of lim but
the bounding box is the bb of lim not the bb of the subscript
Also
a \times \smashoperator[r]\lim_{a very long equation} b_n
should come as
a lim b_n
a very lone eq
where the bounding box of a lim on the right is the bb of the lim,
on the left is the bb of the subscript.
Similarly of \smashoperator[l]

Do you mean that everything between $ $ and \begin{math} \end{math} is

No, I mean the complicated math is much harder in context. Consider

which will typeset as

There is no Context way to do it, and one has to resort to plain tex
\placeformula
$$
\eqalignno{
a = b \formulanumber \cr

= g \formulanumber}
$$
Context gives the same result, but the input syntax is much more verbose
than the latex syntax.
Latex also has a lot of other useful enviromnemts like
\begin{equation}
\begin{split}
a = b \\
= c
\end{split}
\end{equation}
Again, the same effect can be achieved in plain tex, but it is more
verbose.
amsmath also has some useful environments like multalign and aligned,
gathered, faligned, alignat, etc. Some of their functionality can be
achieved using \start stop array from amsl but the amsmath environments
have a lot more features.
There are certain features that are much more difficult to achieve using
context. Consider equation subnumbering. In latex, it is as simple as
\begin{subequations}
\begin{align}
a = b \\
c = d
\end{align}
\end{subequations}
Compare this from how to do this in context (see the wiki). You have to
*manually* set the number of the subequation. Actually, for equation

Browse through http://www-sop.inria.fr/miaou/latex/voss-math.pdf which
explains almost all math tricks in latex. For some of the more complicated
stuff, compare the latex code and the context code to achieve that result.
Context has all the features, but for complicated maths, they are low
level tricks. There is no upper layer like amsmath making life easier for
the user. It will be nice to have such a layer.

(5.1), (5.2)? I would like to manually provide where to start and stop
numbering with x.a or x.1, x.2.
Have a look at the wiki http://wiki.contextgarden.net/Math for the manual
way to number each subformula. I think one can define a
\start(stop)subformula[format = ??] to put a \place(sub)formula
automatically. But I do not know how to define such an environment
properly.
3. How can I put more than one equation in a row and number all of
them (as if they were placed in three columns)?
One way to cheat can be to start a three column mode
\starttext

\startformula

\stopformula

\placeformula

E = mc^2
\stopformula

\placeformula
\startformula

Again, one could define a start-stop environment for this.
4. How can I move the formula number one row lower in case that the
formula is too long and if it would overlap with the formula number

Not sure what you mean here. Context (rather tex, I think) does this by
