find the integral:
integral (4/(x^2+4))2
Ill use S for my integral
So what i did so far is move the 4^2 out of the integral and get this:
16 S 1/(x^2+4)^2
I tried using partial fractions but got nothing. im not sure what to do. So far all I have learned was U sub, integral by parts, partial fractions, and trig substitution.
Would trig substitution work?
if i make x=2tan (theta)
or is there another method i haven't seen yet.
