Could someone help me find the derivative of: (cosx)^(ln(3x)) I'm confused on how to use chain rule here. Thanks.
3* 1/3x * -sinx * ln3x *cos^(ln3x-1)
Oh, any chance you could show me the steps you took?
I am not really sure if its right. But starting from inside take the derivative of everything :-)
