1. The problem statement, all variables and given/known data f(x) = [itex]e^x[/itex] for [itex]-\pi/2 \leq x \leq \pi/2[/itex] 2. Relevant equations 3. The attempt at a solution Having a bit of trouble getting this out. This is a odd function right so [itex] a_n = 0 [/itex] so i only have to find [itex] b_n[/itex] , right?
