I have two problems that I'm having trouble with. Both of them involve square roots in the denominator. I'm not sure how to deal with that. Also, I'm new to the forum so I'm not sure how to make all the math symbols appear. Please bear with me!
1) integrate (1/(x^2-r^2)^(1/2))dx assuming r is some constant
2) integrate ((x+2)/((x^2+4x+5)^(1/2)))dx from 0 to infinity
I'm really stuck, so I'd appreciate any help!!
