I'm a fan of the Fourier theorem, which states that a continuous periodic function f(x) can be represented as the sum of a sine and cosine terms. It's very useful for analyzing signals, especially sound. In fact, Jason Brown from Dalhousie University used a Fourier transform to figure out the notes to the opening chord to The Beatle's 'A Hard Day's Night'!
