How do you differentiate #f(x)=3sqrt(tan4x^2)# using the chain rule? Calculus Basic Differentiation Rules Chain Rule 1 Answer Καδήρ Κ. Jul 18, 2017 #f'(x)=(12x)/(cos^2 4x^2 sqrt(tan4x^2))# Explanation: #f'(x)=3/(2sqrt(tan4x^2))*(tan4x^2)'=# #3/(2sqrt(tan4x^2))*1/(cos^2 4x^2)(4x^2)'=# #3/(2sqrt(tan4x^2))*1/(cos^2 4x^2)*8x=# #(12x)/(cos^2 4x^2 sqrt(tan4x^2))# Answer link Related questions What is the Chain Rule for derivatives?
