How to Compute a FOURIER SERIES // Formulas & Full Example

How do you actually compute a Fourier Series? In this video I walk through all the big formulas needed to compute the coefficients in a Fourier Series. First we see three integrals that will really make everything easier, integrals of products of sin and cos terms of different frequencies.  Then we will use these to compute out formulas for the coefficients of the in and cos terms. Next we see a full example computing everything, and finally see the formulas for the general situation.
