Basic intergration problem still stuck help.

  1. Sep 22, 2009 #1
    The integral is t(4+9t)^(1/2) dt

    I have tried u-sub and integration by parts but i cant figure it out.

    du=9 Does not help because i still have that t to deal with.

    I have spent more time then i want to admit trying to figure it out, and there are plenty more in the hw.

    Can someone help me out so i can move on with the assignment?

    Thanks guys/gals.

    Solve for t in u = 4 + 9t
    and substitute it back into the first t in the integral.
