Question

find the derivative of the function f(x) =ln(cos(tan^-1(2x^3)))

Answer 1

f(x)=ln(x)

\[f'(x)=\frac{1}{x}*x'\]

where x' is the chain rule so dont forget that. I added that in because almost everyone forgets about chain rule.

Answer 2

is that the answer?

Answer 3

I'm sorry but if you really think that is the answer you really need to reread the section of your book and review your class notes.

Answer 4

so what do i do next?

Answer 5

Talk to your professor? I can only help you if you understand derivatives.
