How do you differentiate #f(x)=(t^3)(tan6t)#? Calculus Basic Differentiation Rules Product Rule 1 Answer Joel Kindiak Aug 29, 2015 If it's the correct question, #0# since differentiating constants give you #0#. If the question is #f(t)=(t^3)(tan 6t)#, then by using the chain rule, you should get #f'(t)=(3t^2)(tan 6t)[1 +(2t sec^2 6t)]#. Explanation: #f(t)=(t^3)(tan 6t)# #f'(t)=(3t^2)(tan 6t) +(t^3)(6 tan 6t sec^2 6t) # #f'(t)=(3t^2)(tan 6t) +(3t^2 tan 6t)(2t sec^2 6t) # #f'(t)=(3t^2)(tan 6t)[1 +(2t sec^2 6t)] # Answer link Related questions What is the Product Rule for derivatives?
