Best ResponseYou've already chosen the best response.1so do it piece by piece :) We have a (3x)', what is the derivative of 3x? :D

Best ResponseYou've already chosen the best response.1ok cool, so the first term will simplify to (3)(cos6x). Hmm now we have a (cos6x)' on the right side. We'll take the derivative of the outermost function (cosine) Then "chain" (multiply by the derivative of the inside (6x)' ) So whats the derivative of cos6x? :D

Best ResponseYou've already chosen the best response.0You should give @zepdrix a medal @sandy524 ...i mean, that was a great answer!

Best ResponseYou've already chosen the best response.0ok so after that what do we do

zepdrix

Best ResponseYou've already chosen the best response.1Just combine the pieces together and simplify :D So far we've figured out that the derivative is (3)(cos6x) + (3x)(6sin6x) =3cos6x 18xsin6x Make sense? :D
