WebIterated Chain Rule. At times, we may need to apply the chain rule repeatedly in order to find the derivative. For example, if f (x) = \sqrt {\tan (x^3)} f (x) = tan(x3), the inner function is itself a composite function. In situations like this, we must apply the chain rule more than once. Specifically, for three functions composed, we have. WebThe Chain Rule allows us to use our knowledge of the derivatives of functions f(x) and g(x) to find the derivative of the composition f(g(x)): Suppose a function g(x) is differentiable at x and f(x) is differentiable at g(x). Then the composition f(g(x)) is differentiable at x . Letting y = f(g(x)) and u = g(x), dy dx = dy du ⋅ du dx.
