Hi,
Hello,
For regular formulas involving e.g. rational numbers, I'm sure that
input language for math is quite sufficient, but wonder about drawing
part?
Metapost (Metafun) is your best friend here. You can insert directly in context some MetaFun code, like this:
\starttext
Lorem Ipsum…
\startMPcode
draw ( (0,0) — (1,0) — (0,1)) with color red ;
\stoptext
Look at this entry in the wiki:
Also, you will find a link to the meta fun manual in this page, this a good place to start !
Fabrice.
