Calculus 2. }\) Use that information to write the Taylor series centered at \(0\) for the following functions. }\), Explain why the Taylor series centered at \(0\) for \(e^x\) converges to \(e^x\) for every real number \(x\text{. }\) Based on your graphs, for what values of \(x\) do these Taylor polynomials appear to converge to \(\frac{1}{1-x}\text{? We define polynomials, The defining property of these polynomials is that for each \(n\text{,}\) \(P_n(x)\) and all its first \(n\) derivatives must agree with those of \(f\) at \(x = a\text{. Let us derive the Taylor series of a function f (x), centered at c. Let.
