Homework Equations
I'm guessing trigonometric identities such as sin(a)cos(b) = 1/2(sin(a+b)+sin(a-b)) might be relevant.
The Attempt at a Solution
I've been thinking of some way to get an approximation of each harmonic by working with the Fourier series representation (approximated since it's only sampled for 250ms) of the signal and taking advantage of trigonometric identities but that's about as far as I've gotten, and am having trouble figuring out how I should proceed. Am I in the correct line of thinking so far?
Thanks in advance.
