Re: large right brace grouping lines of equations

[Jeong Dalyoung]

Dear Aditya,

Thank you for suggestion.

Here is my situation.

----- equation1 ---------------------
----  equation 2 ---------------------
-----equation 3 ---- ]
-----equation 4 ---- ] big rbrace for 3,4,5 and some text here
-----equation 5 ---- ]
-----equation 6 --------------------

According to your suggestion, we can use \startmatrix for 3,4,5, but how to put text?
I googled  and found a similar question in LaTeX, but the answer is to use tikz.

How do you think?

Thank you again.

Best regards.

Dalyoung

Do you also want equation numbers? If so, then that is not supported by 
ConTeXt at the moment. If you do not want equation numbers, you can use

\startformula \startalign[n=1]
\NC equation 1 \NR
\NC equation 2 \NR
\NC \startmatrix[left={\left.}, right={\right\}}, n=1, align=middle]
     \NC equation 3 \NR
     \NC equation 4 \NR
     \NC equation 5 \NR
    \stopmatrix
    some text here           \NR
\NC equation 6 \NR
\stopalign \stopformula

With LaTeX, you can also use mathtools package, which is much easier to 
use.

Math support will be reworked at some stage in MkIV.

It works nicely.
I erase \NR after equation 5 because it makes another blank line below eq 5.

Since I am not using a complicate equations, math support in ConTeXt is OK.
And your mathalign is very helpful to me.

Best regards,

You can use \startmatrix[left={\left.},right={\right\}] ... \stopmatrix

large right brace grouping lines of equations

[Jeong Dalyoung]

Dear all,

First, thanks Wolfgang and Hans for suggestions about the chapter head.

Using \cases, I can use large left brace for lines of equations. But, how to put a large right brace after lines of equations which groups them.

Is it possible in the \startformula\startalign ... \stopalign\stopformula?

Thanks

Best regards,

Dalyoung
