Integral Question...

Answer 1

I think is a situation where u-substitution would work out nicely.

Answer 2

which would i use as u?

Answer 3

Whenever doing a u-substitution, you want to take something that's difficult about the integral and see if you can see the derivative of it elsewhere in the integral. As a hint, usually square roots with stuff in it is rough.

Answer 4

it is a set up, since if you pick \(u=1+\sin(x)\) you have \(du\) staring right at you

Answer 5

Got it. Thank you both.

Answer 6

oh, since it is a definite integral, don't forget to change the limits of integration so you don't have to change back

Answer 7

yup thanks
