Chapter 1: Q-16-24MP (page 1)

Use the series you know to show that:
$l n 3 + \frac{{(l n 3)}^{2}}{2!} + \frac{{(l n 3)}^{3}}{3!} + 鈥� = 2$

Short Answer

Expert verified

It is shown that the expansion of series $\ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥� is 2$

Step by step solution

Maclaurin series and the given series.

Series is $\ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥�$
The Maclaurin series ofis given below:

$\begin{array}{rcl} e^{x} = 1 + x + \frac{x^{2}}{2!} + \frac{x^{3}}{3!} + \frac{x^{4}}{4!} + 鈥� e^{x} - 1 = x + \frac{x^{2}}{2!} + \frac{x^{3}}{3!} + \frac{x^{4}}{4!} + 鈥� \end{array}$

Use the Maclaurin series.

Substitute $\ln (3)$ for $x$ in the Maclaurin series of $e^{x} - 1 = x + \frac{x^{2}}{2!} + \frac{x^{3}}{3!} + \frac{x^{4}}{4!} + 鈥�$ as follows:

$e^{\ln (3)} - 1 = \ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥�$

The value of $e^{\ln (3)}$ is given below:

$e^{\ln (3)} = 3$

Substitute $3$ for $e^{\ln (3)}$ in the equation $e^{\ln (3)} - 1 = \ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥�$ as follows:

$3 - 1 = \ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥� 2 = \ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥�$

Thus, it is shown that the expansion of series $\ln (3) + \frac{\ln {(3)}^{2}}{2!} + \frac{\ln {(3)}^{3}}{3!} + \frac{\ln {(3)}^{4}}{4!} + 鈥� is 2$
