What is the derivative of #(arctan x)^3 #? Calculus Differentiating Trigonometric Functions Differentiating Inverse Trigonometric Functions 1 Answer Michael Mar 12, 2016 #f'(x)=(3arctan^2(x))/((x^2+1))# Explanation: #f(x)=arctan^3(x)# Apply the chain rule: #f'(x)=3arctan^2(x).(d(arctanx))/(dx)# #=3xx1/((x^2+1)).arctan^2(x)# #=(3arctan^2(x))/((x^2+1))# Answer link Related questions What is the derivative of #f(x)=sin^-1(x)# ?
