I made a math reference PDF....

I was feeling in the generous mood and made a PDF containing basic integrals and trig identities and such, this way one doesn't have to keep flipping back to the flap of the book to check something :)

Just a heads up for you. You have lost the units on the permittivity constant on page 3. It would be more accuratly called the "Permittivity of free space"

Thanks Integral, I added the units to it.
