Homework Help: Intergration my parts. Reduce.

  1. Sep 17, 2011 #1
    1. The problem statement, all variables and given/known data

    S P^4 e^-P DP

    2. Relevant equations

    My parts.

    3. The attempt at a solution

    I know you can do u = P^4, and DV = e^-P
    Then, you get du = 4P^3 dx and V = -e^-P

    -P^4 e^P + S 4P^3 e^-p dx

    Now, I can just repeat that for the intergral until I get to were the P goes away, but I believe my teacher said something about an easier way. It's called reduce something. Can someone fill me in the name and how it works? Or maybe I heard wrong.
