Question

Is this correct? Trigonometric integral:

Answer 1

second last step

Answer 2

only in the last step
\[u^{-1/2} = 1/(\sqrt{\sin a})\]
and not only sin a in denominator....
rest is correct...

Answer 3

integral of u^-1/2 gives u^+1/2

Answer 4

and yes it should be u^(+1/2) as told by @telltoamit ...which will give u sqrt(sin a) in numerator

Answer 5

Thanks!!!
