Okay the goal is to evaluate this integral
integral sign (I will use S) (sin t^(1/2))/(t^1/2)
so if I let u = t^1/2 and du = dt/2(t^1/2)
S sin u / u du dt/du = I don't know what.
If it was just sin u I would know that it = - cos u + C but I don't know what to do with the denominator.
Please help me.
