1. The problem statement, all variables and given/known data Given the function 10sin^2(10t) Find the fundamental frequency and period. Find the exponential and trigonometric coefficients of the Fourier Series. 2. Relevant equations 3. The attempt at a solution I really have no idea how to start this problem. The sin^2 is what is throwing me off, as im not sure if i am supposed to integrate it first before finding the frequency and period. Any help would be greatly appreciated.
