WebOct 9, 2016 · Explanation: In order to differentiate a function of a function, say y, = f (g(x)), where we have to find dy dx, we need to do (a) substitute u = g(x), which gives us y = f (u). Then we need to use a formula called Chain Rule, which states that dy dx = dy du × du dx. In fact if we have something like y = f (g(h(x))), we can have dy dx = dy df ...
