Convert hand drawn equations to LaTeX
On a somewhat related note, does anyone have any particularly nice ways of writing math-related notes?<p>Part of me wants to just hand-write them and then maybe scan them, but that's not searchable/indexable, and doesn't lend itself well to version control.<p>Writing in TeX or LaTeX would make them searchable/indexable, but this seems a little heavyweight for just notes (like answers to exercises).  I don't use TeX/LaTeX that often, so I feel like I'd be spending half of my mental energy figuring out how to format things, figuring out how to invoke the tools, what packages to install, etc.<p>Are there any nice solutions out there for this sort of thing?
