Question

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

Answer 1

Firstly find the derivates of the functions `ln(cosx)` and `ln(sinx)` as we'll be using them to find the derivative of the trig function: `cos^2xsin^2x` using logarithmic implicit differentiation .

As you know the derivatives of these two isolated functions you can now work towards finding the derivative of `cos^2xsin^2x`...
