Respected guys.

i need ur help ....urgent help bcoz tomorow is my paper.

1);Verify strokes thorem for F=6zi+(2x+y)j-xk where S is upper half of circle x^2+y^2+z^2=1 bounded by close curve c x^2+y^2=1 at z=0 plane

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

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