Hello,
Can anyone please help me with the attached file. Questions (iv) to (vi). Its related to Fourier Series.
Yes, I know how the Fourier series expansion work.
I am having problem with the integration between the limits for question 6 (iv) as you get something like:
∫ (π+t) cos (nt) dt + ∫ (π-t) cos (nt) dt
