$\frac{1}{(1 + x)^{2}}$

Short Answer

Expert verified

The maclaurin series for the given function is

(1 + x)^{鈭� 2} = 1 鈭� 2 x + 3 x^{2} 鈭� 4 x^{3} + 鈰�

Step by step solution

Step 1. Given information

We have been given

$f (x) = \frac{1}{(1 + x)^{2}}$

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

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

Step 3. Binomial series for the given function is

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

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

implies that ,

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

Step 4. The maclaurin series for given function is

The maclaurin series of given function $f (x) = \frac{1}{(1 + x)^{2}}$ is
