Okay but I am referring to an actual book that I can carry in my school bag. Is there a good math formula book out there?

I've got an old copy of the CRC Standard Mathematical Tables. I don't know if it's still in print. It's almost 1.75" thick.

I carry an old copy of a tiny book titled "Engineering Formula's" and have collected a personal notebook of science and math factoids that is also a permanent member of my briefcase.

In addition to the CRC handbook mentioned by Markr--look at Mark's Handbook of Mechanical Engineering (lots of practical physics and math).

I would also learn to use the graphing feature on the Microsoft Excel (one of four programs on Microsoft Office) or its equivalent, and the Mathcad routines.

I want to thank you for your information.
