Find the Fourier Series for the function defined over -5 < x
< 5
f(x) = -2 when -5<x<0 and f(x) = 3 when 0<x<5
You can use either the real or complex form but must show
work.
Plot on Desmos the first 10 terms of the series along with the
original
function.
I know if f(x) is even the fourier series expansion will
consists of consnx, for like f(x)=x^2sinx, or f(x)=2/(3+cosx). but
if the f(x) is neither even or odd, would fourier expansion have
both cosnx and sinnx? This is PDE.
