Now then, im close to shedding a tear with this one.
This integral has been popping up in a few electromag examples iv been doing and i have absolutely no idea whats going on here.
The integral is 1/[(x2+z2)3/2] with respect to x
According to the textbook the answer is x/[z2(x2+z2)1/2]
I initially, without evening really thinking, went straight for -1/(x[x2+z2]1/2)

Use the substitution [itex]x=z \tan u[/itex].
