(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

partial derivative (d/dx) sin(x)cos(x)

2. Relevant equations

Partial Derivatives, product rule

3. The attempt at a solution

sin(2x) = 2 sin x cos x, therefore y=sin(2x)/2

so y'=cos(2x)*(2/2) = cos (2x)?

Is this correct?

Is there an easier way of directly finding the derivative without using substitution?
