Hi...I've been having problems with this question.
The Integral of [sin^3(sqrt(x)) ]/ (sqrt(x))
Should I set sqrt(x) = u and solve from there or should I bring the sqrt(x) in the denominator up?...I'm not even sure if either approach is correct.
Oh ....is it possible to incorporate the reduction formula for sin into this?
The problem I'm having is with that rotten sqrt x in the denominator...even if I do bring it to the numerator, I've still got problems as to how to do it.
Is it possible to set sqrt x = v.
Then approach the problem as sin^3v / v ....I don't think it's possible...but I'm unsure.
I'm not sure on your approach to the problem?
