Question

indefinite∫x45cos(x45)dx
becomes
−1/45∫cos(u)du

i need to convert these in to the limit of
∫0π√45
and if x =
π√45then(u)=what?

Answer 1

x = \[\sqrt[45]{\pi}\] than u =______

Answer 2

You have an indefinite integral here.. You aren't going to plug anything in for x and you don't need the 45th root of pi to solve this.

Answer 3

It will be a mess however. Are you certain that it's not x^44 out front there?
