Homework Statement
Find the derivative of [tex]y=ln(cosh(2x^3))[/tex]
The attempt at a solution
is this the same as saying (1/(cosh(2x^3)) ?
The correct answer is 6x^2 - ((12x^2)/(e^4x^3 + 1))... how do you derive this?
I am really stuck on this question I didn't learn about hyperbolic functions in Calc 1 and now my Calc 2 teacher expects me to know it. Any help is greatly appreciated!
