Governing equation

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.

About this simulation

The full Taylor Series tool models a random walk with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
