Differentiation? Do you mean derivative?

Integrals of derivatives are useful because of that F(b)-F(a) theorem (I forget what it's called).
Nope, I mean differentiation under the integral sign. (Apparently its an easier method of solving complex integrals by differentiating the integrand with respect to a new variable and then integrating that with respect to the original variable, as opposed to integration by parts.)

Sucks.
I miss those books. In GCSE I used to colour the squares in the back pages in with alternating colours until I had a chessboard like pattern.
