Need help with partial fractions integral for flux through a cube?

Homework Statement

integral of: 1/(((L²)/4)+y²)This is for proving the flux through a cube from a wire going through it is = Q_enc/epsilon₀

All that's left for one face after taking out constants is the above equation, and I really don't want to go re learn how to do partial fractions again. Any help?

Use a trig substitution, rather than partial fractions.

alright, was just waiting for someone to say it :)
