Question

Find the derivative of x÷sin^nx .

Answer 1

So I have to find the derivative of

sinnxcos(nx)if n is a positive integer

I've simplified it down to

n(cos(nx))(cos(x))(sinn−1x)+(−n)(sin(nx))(sinn(x))using the product rule but according to my textbook I am supposed to get

n(sinn−1x)(cos(n+1)x)

Could I have some help figuring out where I went wrong?


PLEASE MARK IT AS BRAINLIST

Thank you!
