What is the derivative of #arctan(x)^(1/2)#? Calculus Differentiating Trigonometric Functions Differentiating Inverse Trigonometric Functions 1 Answer Michael Sep 3, 2015 #f'(x)=(1)/(2sqrt(x)(1+x)# Explanation: #f(x)=arctan(x^(1/2))# Using the chain rule: #f'(x)=(1)/(1+x)xx1/2x^(-1/2)# #f'(x)=(x^(-1/2))/(2(1+x))# #f'(x)=(1)/(2sqrt(x)(1+x)# Answer link Related questions What is the derivative of #f(x)=sin^-1(x)# ?
