Hi all,
I have a math equation question too. This has made me pulling my hair
off, for a while. Please see below:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
> \usemodule[amsl]
> \starttext
>
> \startformula
> {\bf f(x)} =
> \cases{
> \sum_{x=1}^n x & if I am false

~~~~~~ I can never make this work for me to start new line
in the equation.
> \displaystyle% just to see the difference
> \sum_{x=1}^n x^2 & \text{if I am true}
~~ this & never seems to give
me the alignment that I need.
> }
> \stopformula
any idea. thanks a lot!!!
Best,
Fei

Hi,
I think the point is to use a \cr after each line of aligned text in \cases.
On my installation the following works fine:
\usemodule[amsl]
\starttext
\startformula
{\bf f(x)} =
\cases{
\sum_{x=1}^n x &\quad if I am false \cr
\displaystyle % just to see the difference
\sum_{x=1}^n x^2 &\quad \text{if I am true} \cr
}
\stopformula
\stoptext
Note that I added a \quad after each "&" in order to have a little
more space: however this is not essential.
Best regards: OK
