My list focuses on things that work in mathematical formulae without using a package, because that’s where I use TeX – for math expressions.
Other web pages:
- Handy LaTeX math reference
- Render LaTeX but copy/paste will paste only a black rectangle. Does an unattractive job on my complex example.
- Render LaTeX VERY SLOW - copy/paste of simple stuff as text works, but copy of image does not. Renders my complex example well.
- Render LaTeX - Chrome plugin. Renders well
For the copy/paste problem, you can work around it by saving the image to disk, opening with Paint, and copying from Paint.
Equation that is tough to render well:
` X(u) = \sum_{n=0}^{N-1} x(n)e^{-i2\pi un/N} `
\( X(u) = \sum_{n=0}^{N-1} x(n)e^{-i2\pi un/N} \)
