Integration using u substitution and arctan

  1. Mar 25, 2008 #1
    so i'm having problems with the coefficients in this problem.


    i know that the main chunk is


    a and b are 5 and 32/5 respectively
    the problem is i can't seem to split up the top so that the first portion is the derivitive of the bottom and that the other top is the right constant.

    Do you mean

    To me it is not clear what you already solved and where your problem is. I suggest you present what you did so far and how you obtained the partial answer (a).
