I am having trouble doing this problem. I know how to do indefinate integrals, but I don't know how to do definate integrals. Can you show me how to do this.
Evaluate
5
(x^32x)dx
2

To get the definite integral subtract the value of the indefinite integral at x=2 from the value at x=5. The arbitrary cnstant c will cancel out.
The indefinite integral is x^4/4  x^2 + C.
The definite integral is
(625/4)  25 [16/4  4].
