Although the author should have specified the period, one might assume from what you were given that the period is P = ?

If you draw another cycle for negative t, would the function look even, odd, or neither?

What are the formulas for a_n and b_n, remembering that u function has values of only 0 or 1.

Answering those questions might get you started.
