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?

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?
