In this section, we strive to understand the ideas generated by the following important questions:. In our work to date in Chapter 8 , essentially every sum we have considered has been a sum of numbers. In particular, each infinite series that we have discussed has been a series of real numbers, such as. This shows one way that a polynomial function can be used to approximate a non-polynomial function; such approximations are one of the main themes in this section and the next. A polynomial function can be used to approximate a non-polynomial function.

In mathematics , a Taylor series is a representation of a function as an infinite sum of terms that are calculated from the values of the function's derivatives at a single point. In the West, the subject was formulated by the Scottish mathematician James Gregory and formally introduced by the English mathematician Brook Taylor in If the Taylor series is centered at zero, then that series is also called a Maclaurin series , after the Scottish mathematician Colin Maclaurin , who made extensive use of this special case of Taylor series in the 18th century. A function can be approximated by using a finite number of terms of its Taylor series. Taylor's theorem gives quantitative estimates on the error introduced by the use of such an approximation. The polynomial formed by taking some initial terms of the Taylor series is called a Taylor polynomial. The Taylor series of a function is the limit of that function's Taylor polynomials as the degree increases, provided that the limit exists.

In Lesson The partial sum is called the nth-order Taylor polynomial for f centered at a. Every Maclaurin series, including those studied in Lesson The coefficient of the term x - 1 k in the Taylor polynomial is given by. This formula is very similar to the formula for finding the coefficient of x k in a Maclaurin polynomial where the derivative is evaluated at 0. In this Taylor polynomial, the derivative is evaluated at 1, the center of the series.

We also derive some well known formulas for Taylor series of e^x f(x)=??n=0 cn(x?a)n=c0+c1(x?a)+c2(x?a)2+c3(x?a)3+c4(x?a)4+? f (x).
