1. The problem statement, all variables and given/known data
Hello people
How would one integrate a function in the form of
∫ ydx/(x2 + y2)3/2

2. Relevant equations
I don't really know how to go about it
3. The attempt at a solution
I tried solving it by substitution but I can't find a suitable one...
any online tutorials for such an integral would be amazing!!!
Thank you

Hello. What substitutions did you try ?

I tried anything with x but that won't work, I checked it online I believe I have to try x = ytanθ... right?
and would it be a double substitution because we have function that the denominator is to the power of 3/2

If you think you need to substitute $x = y \tan(\theta)$, then just go ahead and try it for yourself to see what you get.
