f(x) = f(0)+xf'(0)+\frac{x^2}{2!}f''(0)+\frac{x^3}{3!}f^{(3)}(0)+...+\frac{x^r}{r!}f^{(r)}(0)+...+\frac{x^n}{n!}f^{(n)}(0)

## Summary/Background

The power series is \sin x = \displaystyle \sum_{n=0}^{\infty}\frac{(-1)^n}{(2n+1)!}x^{2n+1}.
The graphs shows approximations to \sin x for n = 0, 1, 2 and 3.
In mathematics, the Taylor series is a representation of a function as an infinite sum of terms calculated from the values of its derivatives at a single point. It may be regarded as the limit of the Taylor polynomials. Taylor series are named in honour of English mathematician Brook Taylor. If the series uses the derivatives at zero, the series is also called a Maclaurin series, named after Scottish mathematician Colin Maclaurin (February 1698 – 14 June 1746).

Maclaurin was a Scottish mathematican who published the first systematic exposition of Newton's methods, written as a reply to Berkeley's attack on the calculus for its lack of rigorous foundations.
