K so here's the deal my final answer doesn't match up with my book's answer I get ((xcos)(sin)(sqrt(1+x^2)/sqrt(1+x^2)

the answer is the same except sin isn't there. Does any know what I might have done wrong I used the chain rule. Thanks

My answer is that but with sin I'll post my scratch work in a bit
