What is the antiderivative of the followring expression?
x^(1/2) sin(2x^(3/2))
After trying to figure out this problem, I have the suspicion that the antiderivative cannot be found using substition method, would this assumption be correct?

Mishaka,
Please, if you don't have anything helpful to contribute, save both of us some time. Please, this problem is really getting to me and I don't want any jokes or nonserious answers, thank you.

Mishaka,
Thank you for the apology, no hard feelings!

Reiny,
I too have messed around with this a bit, and can't see to get anywhere
Tried integration by parts, only got worse and worse.
I sent it through the Wolfram integrator , and it came up with terrible looking answer containing complex numbers.

What level is this?
Are you sure there is no typo?
