In this problem, we have to find the following Fourier coefficients

(1) The first/constant term $a_0$

(2) The first two non-zero cosine coefficients (unless $a_n=0$ for all $n\geq1$)

(3) The first two non-zero sine coefficients (unless $b_n=0$ for all $n\geq1$)

Then we will have to sketch the Fourier series along with the given function, on the specified interval: $x\in[-8,8]$
