11.8: The Binomial Expansion - Mathematics LibreTexts
ウェブ2022年2月2日 · So, for p a real number, a = 1 and b = x, we generalize Equation (11.8.6) as (1 + x)p = ∞ ∑ r = 0(p r)xr and see if the resulting series makes sense. However, we quickly run into problems with the coefficients in the series. Consider the coefficient for r = 1 in an expansion of (1 + x) − 1.
Negative Binomial Theorem | Brilliant Math & Science Wiki
ウェブNegative Binomial Theorem. The binomial theorem for positive integer exponents n n can be generalized to negative integer exponents. This gives rise to several familiar Maclaurin series with numerous applications in calculus and other areas of mathematics. f (x) = (1+x)^ {-3} f (x) = (1+x)−3 is not a polynomial.
