Mathematical Equations
I noticed that many people are entering math like this: x=2y x/2=y But you can use TeX markup to enter math equations like this:

$$x=2y$$ $$\frac{x}{2}=y$$ which is obviously a little nicer. It becomes most useful with more complex equations, where proper rendering is important to be able to easily tell what's being said. Compare lim(x->0) 2sinx^2+tanx/5x^4 to

$$\lim_{x\rarr0} \frac{2\sin x^2}{5x^4}$$

Clearly the TeX markup reduces ambiguity, and doesn't require that the reader know that ^ means exponent (which not everyone does). – Mike.lifeguard  &#124; talk 18:19, 13 February 2008 (UTC)
