Homework Statement
hello
i have to derive this equation
## sec^3(x^3+csc^-1(cot^3\frac{x+4}{3x})) ##
2. The attempt at a solution
## 3sectan^2(x^3+csc^-1(cot^3\frac{x+4}{3x}))*(3x^2-\frac{1}{|cot^3\frac{x+4}{3x}|\sqrt(cot^6\frac{x+4}{3x}-1)})*(-3csc^2\frac{x+4}{3x})*(\frac{3x*1-(x+4)(3)}{9x^2})##
is it so far right?
