Chapter 8: Q 62 (page 680)

In exercises 59-62 concern the binomial series to find the maclaurin series for the given function .
$(1 + x)^{2 / 3}$

Short Answer

Expert verified

The maclaurin series for the given function is

$(1 + x)^{\frac{2}{3}} = 1 + \frac{2}{3} x 鈭� \frac{1}{9} x^{2} + \frac{4}{81} x^{3} + 鈰�$

Step by step solution

Step 1. Given information

We have been given

$(1 + x)^{2 / 3}$

to find the maclaurin series by using binomial series

Step 2.Defining the series

For any non- zero constant p, the Maclaurin series for the function $g (x) = (1 + x)^{p}$

is called the binomial series which is given by ${鈭�}_{k = 0}^{鈭�} 鈥� (\begin{array}{l} p \\ k \end{array}) x^{k}$

where the binomial coefficient is

$(\begin{array}{l} p \\ k \end{array}) = \{\begin{array}{rr} \frac{p (p 鈭� 1) (p 鈭� 2) 鈰� (p 鈭� k + 1)}{k!}, 鈥呪赌呪赌呪赌� if k > 0 \\ 1, 鈥呪赌呪赌呪赌� if k = 0 \end{array}$

Step 3. Binomial series for the given function is

So for the given function $f (x) = (1 + x)^{\frac{2}{3}}$ binomial series is ,

$(1 + x)^{\frac{2}{3}} = {鈭�}_{k = 0}^{鈭�} 鈥� (\begin{array}{l} \frac{2}{3} \\ k \end{array}) x^{k}$

implies that ,

$\begin{aligned} (1 + x)^{\frac{2}{3}} = (\begin{matrix} \frac{2}{3} \\ 0 \end{matrix}) x^{0} + (\begin{matrix} \frac{2}{3} \\ 1 \end{matrix}) x^{1} + (\begin{matrix} \frac{2}{3} \\ 2 \end{matrix}) x^{2} + (\begin{matrix} \frac{2}{3} \\ 3 \end{matrix}) x^{3} + 鈰� \\ = 1 + \frac{2}{3} x + \frac{\frac{2}{3} (鈭� \frac{1}{3})}{2!} x^{2} + \frac{\frac{2}{3} (鈭� \frac{1}{3}) (鈭� \frac{4}{3})}{3!} x^{3} + 鈰� \\ = 1 + \frac{2}{3} x 鈭� \frac{1}{9} x^{2} + \frac{4}{81} x^{3} + 鈰� \end{aligned}$

Step 4. The maclaurin series for given function is

The maclaurin series for the given function is $(1 + x)^{\frac{2}{3}} = 1 + \frac{2}{3} x 鈭� \frac{1}{9} x^{2} + \frac{4}{81} x^{3} + 鈰�$
