okay, so the problem is:

integral from 2 to 6 y/(y-2)^1/2 dy

i know you have to start by saying lim a-->2+ integral from a to 6 y/(y-2)^1/2

but then i'm kind of blanking on how to integrate/go from there

let

integrate, back substitute, then evaluate your improper integral - March 8th 2009, 06:32 PMbuttonbear
should i be getting a negative answer for this..?

i got -8/3

it is possible, you can get a negative answer

and since it is a**proper integral**, you can check the answer even with a ti-83 plus. - March 8th 2009, 07:29 PMbuttonbear
would you mind telling me how to do that? :x

edit:

i got it, nevermind, thank you very much!
