Math 2200 Homework 7 (Complete by Friday November 12th) Remember to show your work!
 

Summary: Math 2200 Homework 7 (Complete by Friday November 12th)
Remember to show your work!
Problem 1 Suppose that p(x) is an nth degree polynomial, find a general formula for
p(x) ex
dx
Solution: Let U = p(x), dV = ex
dx then dU = p (x)dx and v = ex
so
p(x) ex
dx = p(x)ex
- p (x) ex
dx
Apply the formula many times and we get:
p(x) ex
dx = ex

degree(p)
k=0
(-1)k
p(k)
