Chain rule - Wikipedia, the free encyclopedia

Anyway, here is the math:

1.

Now becomes

2. Differentiate:

What you did is that you used the product rule. Only use the product rule when you have something like this: Here, is a function of , and is a function of as well.

Your question is however: It means that is a function of , and is a function of - December 4th 2010, 05:29 PMHellbent
