One of those questions that Google gives you 1000 irrelevant answers for: Given N summed sine waves, all of frequency X, with N different phase shifts and amplitudes, what is the resulting amplitude? Integrating them in discrete steps over time and finding the maximum seems like a clumsy way of doing it.
I guess it would help to reword it to "find the new phase and amplitude given two summed sine waves" and then iterate over that.

Okay, so... Transforming each sine wave into a phasor (complex number representation) would let you sum each phasor to produce a new phasor, but that still only gives you an answer for a single instant in time.
My gut feeling tells me that I might need some calculus to solve this.
