Re: [NTG-context] Math align question
Aditya,
This confuses me, I thought when using 3 columns I have to set n=3
otherwise I get errors about extra tab found etc.
However doing as you suggested, seems to work.
Then another question, the formula numbering is not aligned with the
other formula's in my text
like in the code below. How can I force the sub formula numbering to be
right aligned ?
Thanks
Wim

How about

This is due to the m key. m=2 tells context that there are two blocks
of equations. n=2 says that each block has two columns. So, in all
there should be n*m = 4 \NC in the equation (I had only put three,
which led to the wrong equation number alignment).
Then another question, the formula numbering is not aligned with the other
formula's in my text

aligned ?
See above: This was due to mistake in my code. This works. (Though it
will be nice if such mistakes do not cause these kinds of errors)

You can also refer to the whole equation~\in[calcb-chapter-4-eqn5], or
an individual number~\in[calcb-chapter4-eqn5:iii].

BTW, why no \ms before dx, and a \ms before dy?

I read the Myway on math align and there are examples where one can set the distance but only for pairs of equations. In the following code I have 3 columns but they are too close together and I want to spread them out.
