# Trying to solve an integral

Friends i am trying to solve an integral since few days didnt succeed can you help me out. $\int_{0}^{\pi}\frac{(a-bcos\theta)d\theta}{(c-dcos\theta)^{\frac{3}{2}}}$ a b c and d are constants

I have got it in the expression of electric or magnetic fields of a large no. of arrangements I have tried. This is used to find the magnetic field due to current carrying circular loop at a general point in its plane.I remember other instances too (in E+M) , where this is used. I have never been able to solve it though!(But approximations can be done if $$d << c$$)

Same here I did the same to solve your problem. Do you read David morin Edward Purcell electricity and magnetism

No, do you?

I have heard this name for first time!

Yes it is one of the best books I have ever seen for physics
