We won’t prove this. Theorem 7.2. 1: Generalised Binomial Theorem. For any n ∈ R, (7.2.6) ( 1 + x) n = ∑ r = 0 ∞ ( n r) x r. Around 1665, Isaac Newton generalized the binomial theorem to allow real exponents other than nonnegative integers. (The same generalization also applies to complex exponents.) In this generalization, the finite sum is replaced by an infinite series. In order to do this, one needs to give meaning to binomial coefficients with an arbitrary upper index, which cannot be done using the usual formula with factorials. However, for an arbitrary number r, one can define
