I found a cool html equation editor online based on a superset of the LaTeX markup language that allows me to code some important equations you should know about. You can find the site Here . You can also click on any equation to see its LaTeX source.

### Fourier Expansion of a periodic function in three dimensions

This equation is quite important, and I’m using it right now in my Solid State physics class to help define crystal structure. The constants may be found by the following correlary function:

### Maxwell’s equations of electricity and magnetism

These bad boys will solve anything to to with E and M; including optics.
