1) integrate 1/Sqrt(25-9x^2) dx
2) integrate cos x/(1+sin^2 x) dx from 0 to pi/3
I attempted using U-substitution, but it doesn't seem to make sense. After reviewing my professor's notes and my Calculus, i cannot find a method to solve these last two questions of my homework. I don't want to give up, I'm sitting in class with 89% and i want to pass with an A.
Please show your steps, so that i may also learn.
Any help is appreciated, Thank you!
