Proof that π is irrational connection between the proofs lies in the fact that Hermite already mentions that if "f" is a polynomial function and then from which it follows that Bourbaki's proof is outlined as an exercise in his calculus treatise. For each natural number "b" and each non-negative integer "n", define Since "A"("b") is the integral of a function which defined on [0,] that takes the value 0 on 0 and on and which is greater than 0 otherwise, "A"("b") > 0. Besides, for each natural number "b", "A"("b") < 1 if "n" is large enough, because and therefore On the other hand,
