The chain rule states dy dx = dy du × du dx In what follows it will be convenient to reverse the order of the terms on the right: dy dx = du dx × dy du which, in terms of f and g we can write as dy dx = d dx (g(x))× d du (f(g((x))) This gives us a simple technique which, with some practice, enables us to apply the chain rule directly Key Point
