Integration methods help!

  1. Mar 20, 2013 #1
    1. The problem statement, all variables and given/known data

    Please view the images, i am quite confused(although i know basics). I would very much appreciate an explanation as to how to solve these problems. The step by step approach.

    Again, i would appreciate any response explaining how to do this.

    2. Relevant equations

    For part A, the options are...
    1. Power rule
    2. logarithym rule
    3. Exponential rule
    4. Trig rule
    5. Inverse trig rule

    3. The attempt at a solution

    Seems to me Exponential Expansion'd be better.. But what kind of question is this, anyways?

    I don't think the questions are in parts, as such. I think you're supposed to choose the best option between those "parts" - i.e. if you think you can the integral directly, then choose the first option. If you think you should sub, choose the second, etc.
