# Math Help - Integral calculation

1. ## Integral calculation

Hi,

This is the first time I post here. I hope I will do everything correctly

I would like to know how to calculate this expression:

$\int_{a}^{b} \frac{x^2-1}{(x^2+y^2+z^2)^{5/2}}dx$

I am pretty sure it exists a kind of method for it.

Thanks in advance.

2. put $a^2=y^2+z^2,$ it's a constant, since you're integrating w.r.t. $x.$
