LaTeX Crib Notes

Description Markup Example
newline \\
exponent ^ \( x^2 \)
union \cup \( \cup \)
intersection \cap \( \cap \)
space ~
tilde '\sim' \( \sim \)
tilde ~ outside of TeX ~
backslash \backslash \
x over y (division) x \over y \(x \over y \)

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}

\( X(u) = \sum_{n=0}^{N-1} x(n)e^{-i2\pi un/N} \)
