Hello. I use LaTeX a lot for homework and stuff like that. I also use it to email questions and stuff like that to proffessors. Anyway, i am pretty proficient at it and its syntax but sometimes it gets hard to make equations. On my mac, i often use Grapher (a surprisingly powerful built in program) and i just write equations in there and it has a LaTeX export. Is there something similar for PC? When i am in the computer lab, it would be nice to have similar functionality. Basicically I am looking for a program that will allow me to use something like an equation editor in WYSIWYG type format and then export. Any ideas would be appreciated.
