# calc help?

z(x)=sin(cos(tan(3x))).

Im really confused. If you could please show the steps or explain how to start it would be very helpful.

Update:

find the derivative of z(x)=sin(cos(tan(3x))).

Help with what? Do you need the derivative?

cos(cos(tan(3x))) * (-sin(tan(3x))) * sec(3x)^2 * 3 =>

3 * sec(3x)^2 * sin(tan(3x)) * cos(cos(tan(3x)))
