What is the derivative of #arcsin(x^2/4)#? Calculus Differentiating Trigonometric Functions Differentiating Inverse Trigonometric Functions 1 Answer Matt B. Nov 22, 2016 #d/dx(arcsin(x^2/4)) = x/(2sqrt(1-x^4/16))# Explanation: Let #u=x^2/4# #d/dx(arcsinu) = 1/sqrt(1-u^2) * d/dx(u)# #d/dx(u) = x/2# The rest is just plugging in and multiplying #u#.
