What is the derivative of #f(x)=tan^-1(e^x)# ? Calculus Differentiating Trigonometric Functions Differentiating Inverse Trigonometric Functions 1 Answer Wataru Aug 30, 2014 By Chain Rule, we can find #f'(x)=frac{e^x}{1+e^{2x}}#. Note: #[tan^{-1}(x)]'={1}/{1+x^2}#. By Chain Rule, #f'(x)={1}/{1+(e^x)^2}cdot e^x={e^x}/{1+e^{2x}}# Answer link Related questions What is the derivative of #f(x)=sin^-1(x)# ?
