8.6 the binomial theorem
... Pascal’s triangle of binomial coefficients. Nonetheless, the multiplication of ~a 1 b!4 by ~a 1 b! to get the expansion for ~a 1 b!5 contains all the essential ideas of the proof. We still lack a closed-form formula for the binomial coefficients. We know, for example, that the fourth term of the exp ...
