I was wondering what the rule was about three different equations multiplied together. I know how to use the chain rule using 2 equations multiplied together, but was wondering what to do with 3. Thanks!

I think you might be referring to the product rule. $\displaystyle (f(x)g(x))' = f'(x)g(x) + f(x)g'(x)$ $\displaystyle (f(x)g(x)h(x))' = f'(x)g(x)h(x) + f(x)g'(x)h(x) + f(x)g(x)h'(x)$ Do you see the pattern here?
