How do you differentiate #f(x)=(x-sin3x)^3/9# using the chain rule? Calculus Basic Differentiation Rules Chain Rule 1 Answer Dr. S Jan 9, 2018 #1/3*(1-3cos3x)*(x-sin3x)^2# Explanation: #d/dy(((x-sin3x)^3)/9)# = #d/dy(1/9(x-sin3x)^3)# = #1/9*3*(1-cos3x*3)*(x-sin3x)^2# = #1/3*(1-3cos3x)*(x-sin3x)^2# Answer link Related questions What is the Chain Rule for derivatives?
