[NTG-context] Re: Problem with \startlinenumbering left and right arguments

Dear List,

In the MWE below, the left and right arguments are not applied in the
last chapter. How can this be fixed?

\starttext
\startlinenumbering[left={[},right={]}]

\dorecurse{5}{%
\startchapter[title={Knuth}]
\samplefile{knuth}
\stopchapter
}

\stoplinenumbering
\stoptext


When you have a single linenumbering block in your document you can set
the left/right values at the begin of your document with

    \setuplinenumbering[left={[},right={]}]

When you have multiple linenumbering blocks in your document you can
ensure the values stay also on the last page with a forced page break before
the block ends, e.g.

    \page
    \stoplinenumbering

Very clear !
In typography for Mathematics books, what choice should we make for 
the best possible result ?


A question better answered by Mikael or Aditya!

Or, for inline math, $\sqrt{1/3}$.

Hi Wolfgang,
I'm reading this thread and I'm interested because I type a lot of 
text with mathematical formulas.
In fact, I find that \dfrac{} creates unsightly leading space and that 
\frac{} is too small. What is the difference between \frac{} and 
\tfrac{} ?


\frac switches the math style while \tfrac (textstyle), \dfrac 
(displaystyle) and \sfrac (scriptstyle) enforce a certain style.


 begin example
\startbuffer[frac]
\frac{1}{2} + \dfrac{1}{2} - \tfrac{1}{2} + \sfrac{1}{2}
\stopbuffer

\starttext

\startformula
\getbuffer[frac]
\stopformula

\m{\getbuffer[frac]}

\startformula
  \frac
    {\getbuffer[frac]}
    {\getbuffer[frac]}
\stopformula

\m{\frac
  {\getbuffer[frac]}
  {\getbuffer[frac]}}

\stoptext
 end example

Wolfgang

I worked, ;-), thanks.
Let me ask you another thing, how can I avoid messing up the
line spacing by using \sqrt and \frac, the line that follows these has increased
line spacing in the pdf output

code:
Find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\frac{3}{13}}$, $m=\sqrt{\frac{1}{13}}$, and $n=\sqrt{\frac{9}{13}}$.


Complete working minimal examples are preferred over code snippets.

To avoid single lines with different spacing you can either increase the 
line spacing for all
lines with \setupinterlinespace or you use a different fraction command 
which uses

smaller numbers or creates inline fractions.

Hi all,
I am generating a quiz, with eight questions, each
with text and a figure following it. The output was fine till the
fifth question, but then the margin separating the  text of
each question disappeared and the figure got put on the
next page one after the other.
Can anyone suggest what I could be doing wrong?


Without a proper example it's difficult to give an answer.


Do I need to increase the buffer? how?


This is what I have used to place each figure
\startplacefigure[location=here,reference=fig:blah][]{}
  \externalfigure[blah.jpeg][scale=300]
\stopplacefigure


You can try the force option:

\startplacefigure[location=force,reference=fig:blah]
  \externalfigure[blah.jpeg][scale=300]
\stopplacefigure
