Given the function 10sin^2(10t)

Find the fundamental frequency and period.

Find the exponential and trigonometric coefficients of the Fourier Series.

## Homework Equations

## 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.
