Taylor & Maclaurin Series

Expand functions as Taylor and Maclaurin series, with derivatives evaluated at the centre and the general term shown. Try “Maclaurin series of eˣ up to x⁴”.

Try an example:

How the Taylor & Maclaurin Series works

  1. Compute the derivatives of f at the centre point (0 for Maclaurin).
  2. Substitute into f(a) + f′(a)(x − a) + f″(a)/2!·(x − a)² + …
  3. Simplify the terms and state the radius of convergence.

Frequently asked questions

What is the difference between Taylor and Maclaurin?

A Maclaurin series is a Taylor series centred at x = 0.

What is the Maclaurin series of eˣ?

1 + x + x²/2! + x³/3! + x⁴/4! + …, which converges for every x.
