Chapter 8: Q 22 (page 704)

Find the indicated Maclaurin or Taylor series for the given function about the indicated point, and find the radius of convergence for the series.
$\frac{1}{x}, x_{0} = - 1$

Short Answer

Expert verified

The radius of convergence for the series is $P_{n} (x) = - {鈭�}_{k = 0}^{鈭�} (x + 1)^{k}$

Step by step solution

Given information

The function is $f (x) = \frac{1}{x}$

Find the general of the Taylor series of the function

The Taylor series at $x = - 1$ for any function $f$ with a derivative of order $n$ is given by

$P_{n} (x) = f (- 1) + f^{'} (- 1) (x + 1) + \frac{f^{''} (- 1)}{2!} (x + 1)^{2} + \frac{f^{'''} (- 1)}{3!} (x + 1)^{3}$

$+ \frac{f^{''''} (- 1)}{4!} (x + 1)^{4} + 鈥�$

As a result, first, determine the function's value as well as $f^{'} (x), f^{''} (x), f^{'''} (x)$ at $x = - 1$

Furthermore, the function's general Taylor series is $P_{n} (x) = {鈭�}_{k = 0}^{鈭�} \frac{f^{k} (x_{0})}{k!} {(x - x_{0})}^{n}$

Make a table of the Taylor series for the function f(x)=1x at x=-1

$n$	$f^{n} (x)$	$f^{n} (- 1)$	$\frac{f^{n} (- 1)}{n!}$
$0$	$\frac{1}{x}$	$- 1$	$- 1$
$1$	$- \frac{1}{x^{2}}$	$- 1$	$- 1$
$2$	$\frac{2}{x^{3}}$	$- 2$	$- 1$
$. . .$	$. . .$	$. . .$	$. . .$
$k$	$\frac{(- 1)^{k} k!}{x^{k + 1}}$	$- k!$	$- 1$

Find the Taylor series for the function f(x)=1x at x=-1

The Taylor series for the function $f (x) = \frac{1}{x}$ at $x = - 1$ is

$- 1 - 1 (x + 1) - 1 (x + 1)^{2} + 鈰� + (- 1) (x + 1)^{k} + 鈥�$

Or, $P_{n} (x) = - {鈭�}_{k = 0}^{鈭�} (x + 1)^{k}$
