Explaining the chain rule

  1. Dec 1, 2006 #1
    1. The problem statement, all variables and given/known data

    The question is: How would you explain the chain rule to a classmate?

    My teacher wants: 1.a graph, 2. in words, 3. using math
    2. Relevant equations

    3. The attempt at a solution

    I said: for the function y=f[g(x)], the chain rule is d/dx[g(x)].

    Whats the graph like?

    What do you mean by d/dx[g(x)]?

    DERIvative of g(x)...

    You should have written it as: [tex] y'(x) = f'(g(x))g'(x) [/tex]. What you have written is not the chain rule.
