Best ResponseYou've already chosen the best response.3so f(x) = Ln(x) g(x) = Ln(x) h(x) = f(g(x)) = Ln(Ln(x))

Best ResponseYou've already chosen the best response.3if we had f(x) = Ln(x), what would be the derivative?

jim_thompson5910

Best ResponseYou've already chosen the best response.3yes, now what we do is replace the 'x' with Ln(x) dw:1441070946608:dw

Best ResponseYou've already chosen the best response.3or put another way, we replace x with g(x) = Ln(x)

jim_thompson5910

Best ResponseYou've already chosen the best response.3and then we multiply by the derivative of the inside we multiply by g ' (x)

Best ResponseYou've already chosen the best response.3g(x) = Ln(x) g ' (x) = 1/x dw:1441071005586:dw

Best ResponseYou've already chosen the best response.3here's a page with tons of chain rule practice problems https://www.math.ucdavis.edu/~kouba/CalcOneDIRECTORY/chainruledirectory/ChainRule.html they have detailed solutions to help explain and help you practice more
