I am trying desperately to figure out a Fourier series question i have been given and have hit a big mental wall can someone please help and maybe point me in the right direction.

The problems i have been given are:-

a) f(t)=e[^2t] 0<t<1 (cosine series)

b) f(t)=e[^2t] 0<t<∏ ( sine series)

working on the sine series i have that the a[n] terms will =0 and there will be no a[0][/2] term

What i have so far is:-

b[n]=[2][/p] ∫p][/2]&-[p][/2] F(t)sin ([2n∏t][/p]).dt

=[2][/2] ∫1 & -1 [e][^2t]sin (2n∏t).dt

how does this look so far?

Any help is appreciated, thanks
