Plz help me in solving these problems regarding Fourier Series:

1):Find Fourier Sine Series for f(x)=x^2 -Π(pie)<x<Π(pie)

and deduce Π^2/12=1-1/4+1/9-1/16 +-------------------

Π indicates PIE

2):With the help of fourier Sine series and Fourier Cosine series

f(x)=x+1 0<x<Π(pie)

Deduce 1-1/3+1/5-1/7 --------------------- = Π(pie)/4

and 1+1/(3^2)+1/(5^2)+1/(7^2)--------= Π^2/8

3);Find the fourier Sine series for function f(x) =e^x 0<x<Π(pie)
