Chapter 8: Q 15 (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.
$\sin x, x_{0} = 0$

Short Answer

Expert verified

The Maclurin series for the function is $f (x) = {鈭�}_{k = 0}^{鈭�} \frac{(- 1)^{k}}{(2 k + 1)!} x^{2 k + 1}$

Step by step solution

Given information

The function is $f (x) = \sin x$

Find the general of the Maclurin series of the function

The Maclurin series at $x_{0} = 0$ for any function $f$ with a derivative of order $n$ is given by

$f (x) = f (0) + f^{'} (0) x + \frac{f^{''} (0)}{2!} x^{2} + \frac{f^{'''} (0)}{3!} x^{3} + \frac{f^{''''} (0)}{4!} x^{4} + 鈥�$

The function's general Maclurin series is

f (x) = {鈭�}_{n = 0}^{鈭�} \frac{f^{n} (0)}{n!} x^{n}

Make a table of the Maclurin series for the function f(x)=sinx

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

Find the Maclurin series for the function f(x)=sinx

The Maclurin series for the function $f (x) = \sin x$ is:

$0 + 1 路 x + \frac{0}{2!} x^{2} + \frac{(- 1)}{3!} x^{3} + 0 x^{4} + \frac{1}{5!} x^{5} + \frac{0}{6!} x^{6} + 鈥�$

Or, we can write as:

$f (x) = {鈭�}_{k = 0}^{鈭�} \frac{(- 1)^{k}}{(2 k + 1)!} x^{2 k + 1}$
