What is the derivative of #y= tan^-1(x^2)#? Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos(x) and y=tan(x) 1 Answer Konstantinos Michailidis Dec 26, 2015 The derivative of #arctanf(x)# is #d(arctanf(x))/dx=(f'(x))/(1+(f(x))^2)# where #f(x)=x^2# hence #d(arctanx^2)/dx=(2x)/(1+(x^4))# Answer link Related questions What is the derivative of #y=cos(x)# ?
