What is the derivative of #g(x)= x^2*sqrt(1-x^2)#? Calculus Basic Differentiation Rules Chain Rule 1 Answer Massimiliano Apr 14, 2015 The answer is: #y'=(2x-3x^3)/sqrt(1-x^2)#. For the product rule: #y'=2x*sqrt(1-x^2)+x^2*1/(2sqrt(1-x^2))*(-2x)=# #=2x*sqrt(1-x^2)-x^3/sqrt(1-x^2)=(2x(1-x^2)-x^3)/sqrt(1-x^2)=# #=(2x-3x^3)/sqrt(1-x^2)#.
