The paper gives a remarkably simple proof to the Faà di Bruno formula, which expresses higher derivatives of a composite function. The paper points out that a proof for composition of polynomials is sufficient, and then shows that the result for composition of polynomials is an easy consequence of the multinomial theorem.
