How do you differentiate #f(x) =x sqrt(4-x^2) # using the product rule? Calculus Basic Differentiation Rules Product Rule 1 Answer S S. Feb 15, 2018 #-x^2/sqrt(4-x^2)+sqrt(4-x^2) # Explanation: #d/dx(xsqrt(4-x^2) )=xd/dx(sqrt(4-x^2 ))+d/dx(x)sqrt(4-x^2)=x(1/2(4-x^2)^(-1/2)(-2x)+1sqrt(4-x^2)=-x^2/sqrt(4-x^2)+sqrt(4-x^2)# Answer link Related questions What is the Product Rule for derivatives?
