Question

Help, Evaluating Intergrals using substitution prior to intergration by parts.

Answer 1

\[\int\limits e^\sqrt(3s+9)\]

Answer 2

let a = 3s + 9, then da = 3ds
then multiply and divide by 3, to get the 3*ds in da
(1/3) Int(e^(sqrt(a)) da)

Answer 3

but that's not going to help!

Answer 4

yes it will

Answer 5

\[\int\limits_{}^{}e^\sqrt{a}da\]

Answer 6

(1/3) * \[\int\limits_{}^{}e^\sqrt{a}da\]

Answer 7

what about the u & dv?

Answer 8

now let b^2 = a

Answer 9

da = 2b*db

Answer 10

wait i got lost myself..
