Taylor's Theorem For Power Series
Taylor's Theorem For Power Series : Statement : Let ∞ Σ aₙ xⁿ be a power series with n= 0 radius of convergence R , and let ∞ f(x) = Σ aₙ xⁿ , |x| < R n=0 Then for any a∈ ]-R ,R[ , prove that f can be expanded in a power series about 'a' which converges for |x-a| < R- |a| , and ∞ f(x) = Σ...
