HI I think I am getting more lost as the day progresses.

Basically I have the definite integral sign (sin t^1/2)/(t^1/2)

so I know the antiderivative of sin t^1/2 = -cos t^1/2 + C but I don't know if I need to do something with the ^1/2 on the numerator and I don't know what to do with the denominator

Any direction would be greatly appreciated.
