Homework Help: Integration problem

  1. Mar 9, 2007 #1
    For part of a problem, how would I integrate:

    (e^2t+e^-2t+2)^(1/2) with respect to t

    I have no idea..., but I've tried integration by parts to start...

    can you transform e^2t+e^-2t+2 into a perfect square?

    Ok, i see now. Thanks.

    I have another problem now... I found the solution to be a=exp(t)-exp(-t) and I need to find the inverse of a. Taking the ln of each side didn't help at all.

    multiply by exp(t) and bam you got a quadratic!
