# How do you find the derivative of the trig function (cos^2(x)sin^2(x))?

Firstly find the derivates of the functions $\ln \left(\cos x\right)$ and $\ln \left(\sin x\right)$ as we'll be using them to find the derivative of the trig function: ${\cos}^{2} x {\sin}^{2} x$ using logarithmic implicit differentiation .
As you know the derivatives of these two isolated functions you can now work towards finding the derivative of ${\cos}^{2} x {\sin}^{2} x$...
