f (x) \approx n = 0 \sum 5 \frac{f ^{(n)} ( 0 )}{n !} (x - 0)^{n}

Reading this result: The order-5 Taylor polynomial of sin(x) is built about the center a = 0. With 5 terms the fit near a is excellent and tracks f across a wider window, though it still degrades outside the radius of convergence. Every extra term improves the local fit near a, but the approximation is only trustworthy inside that radius.
