Help using latex

  1. Jan 29, 2010 #1
    Hello. I have a very large, very complex equation to post here at the forums. I just finished writing it in Latex but I am having problems posting it. In the past I have always used the short cut keys, but this time a wrote out the whole thing.

    Here is one part in Latex:
    [tex]A= (cos(2ka)-(i\epsilon/2)sin(2ka))e^{2ia\lambda}F+(i\eta/2)sin(2ka)G[/tex]

    Does anyone know how to make that look like I want it to?

    [tex]\sin \theta[/tex]​
    Also, you can click on any Latex equation to view the code used to make it.
