Homework Statement
S P^4 e^-P DP
Homework Equations
My parts.
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.
