Question

Help finding the antiderivative of a composite function.

Answer 1

\[\int\limits_{.}^{.}3\cos(x^2/2)dt\]

Answer 2

I tried U-substitution, but that didn't work, so I assume I have to use substitution by parts, but I don't understand how that's possible.

Answer 3

What did you make u?

Answer 4

You don't use by parts.

Answer 5

I made U=1/2x^2

Answer 6

I kind of see what you're getting at. I had to make U=cos(x^2/2), right?

Answer 7

Nah not going to work

Answer 8

This can not be integrated in terms of conventional functions. That is you can not manipulate using algebraic rules.

Answer 9

He is abs. right.
