WebLet's start with the definition of the derivative and try to arrive at this result: Given: y = f ( u ( x )). By simple algebra, we know that Then: Differentiablility implies continuity; therefore … WebThe chain rule is defined as the derivative of a composition of at least two different types of functions, such as: y’ = \frac {d} {dx} [f \left ( g (x) \right)] y’ = dxd [f (g(x))] where g ( x) is a domain of the function f ( u ). We can also call the function f as the external function and the function g as the internal function.
