Chapter 10.3, Problem 1P

a.

To determine

The Fourier series for the extended function $f\left(x\right)=\{\begin{array}{l}-1,-\pi \le x<0\\ 1,0\le x<\pi \end{array}$.

b.

To determine

To graph: The function $f\left(x\right)=\{\begin{array}{l}-1,-\pi \le x<0\\ 1,0\le x<\pi \end{array}$ which converges for three different periods.
