Answer 1

by parts

Answer 2

sorry, I don't know if I've learned that. all we've done is u sub. Do I need to integrate if this is the question: Use the function P defined as 20 + 10te^(-t/3) to find the average value over [0,15]

Answer 3

average value is a integration yes

Answer 4

ok. so im not sure how to integrate that using what i know so far, which is basically u sub.

Answer 5

I can only think of one way to integrate that and that is by parts
