I need help with writing a full step-by-step solution for the following Fourier Series question.
fourier series for the following function:
f(x) = 1 for -pi < x < 0
= x for 0 < x < pi
Find An, Bn
An = 1/pi (limit -pi to 0) f(x) cos nxdx + 1/pi (limit 0 to pi) f(x) cos nxdx
Bn = 1/pi (limit -pi to 0) f(x) sin nxdx +1/pi (limit 0 to pi) f(x) sin nxdx
I have found the other ones but don't understand this part.
