WebA useful special case of the Binomial Theorem is (1 + x)n = n ∑ k = 0(n k)xk for any positive integer n, which is just the Taylor series for (1 + x)n. This formula can be extended to all real powers α: (1 + x)α = ∞ ∑ k = 0(α k)xk for any real number α, where (α k) = (α)(α − 1)(α − 2)⋯(α − (k − 1)) k! = α! k!(α − k)!. http://people.qc.cuny.edu/faculty/christopher.hanusa/courses/Pages/636sp09/notes/ch5-1.pdf
