If #f(x) =csc^3(x/4) # and #g(x) = sqrt(x^3+3 #, what is #f'(g(x)) #? Calculus Basic Differentiation Rules Chain Rule 1 Answer Bdub Apr 14, 2016 #(f(g(x)))'= 3 csc(1/4 sqrt(x^3+3))^2 xx -csc(1/4 sqrt(x^3+3))cot(1/4 sqrt(x^3+3)) xx1/(8sqrt(x^3+3)) xx3x^2# Explanation: #f(g(x))=csc^3(1/4 sqrt(x^3+3))# #(f(g(x)))'=f'g(x) xxg'(x)# #(f(g(x)))'= 3 csc(1/4 sqrt(x^3+3))^2 xx -csc(1/4 sqrt(x^3+3))cot(1/4 sqrt(x^3+3)) xx1/(8sqrt(x^3+3)) xx3x^2# Answer link Related questions What is the Chain Rule for derivatives?
