Actually I have looked at that, but it is hard to read. I should probably go through it and make a Maxima equation or function out of every formula in the book or at least the important ones to me. That would help me to remember them.
I have been up all night again. Bye.

You might want to check the handbook of mathematical functions
by Abramowitz and Stegun.
