    Undergrad Integral Proof: u^2-a^2 | Detailed Explanation

    Thanks guys... The solution swapnilster proposed is correct. I also did his solution before. But after the trigonometric substitution I was stuck at the answer \frac{1}{2}ln \frac{(u+a)}{\sqrt{u^2-a^2}}+ C This is where I started to need some help from you guys. But after...
