How Can I Solve This Electric Field Integral?

[PhysicsGirl90]

Hey guys,

While trying to calculate the electric field above a spherical shell i ran into this integral that i am having some difficulty solving.

∫[(z-Ru)/(z^2+R^2-2zRu)^(3/2)] du

-1 < u < 1

(z and R are known constants)

Can anyone help point me in the right direction? Thx

its easy ...keep trying or if u still dnt gt it dis integration is solved in any std physics book...

and if you can't get it , you can solve it by wolfram http://www.wolframalpha.com/input/?i=integral+%28a-b*x%29%2F%28a^2%2Bb^2+-+2*a*b*x%29^%283%2F2%29+dx
