Latex Tips And Tricks

1. When you get an extra alignment tab error while working with a eqnarray, it could be due to the fact that you have forgotten to put the "\nonumber" at the end of every line. That is of course, if you do not want to number the equations. This will occur only if you use equations that contain terms that are split across lines. That is if every line begins with a "=" or other relational operator you won't face this problem at all. Where you will face this problem is if you begin some line with a "+", i.e. you have split some expression on the right hand side.
