Chapter 3: Q. 22 (page 310)

Calculate each of the limits in Exercises 21–48. Some of these limits are made easier by L’Hopital’s rule, and some are not
$\lim_{x \to 1} \frac{x - 1}{e^{x - 1} - 1}$

Short Answer

Expert verified

The value of $\lim_{x \to 1} \frac{x - 1}{e^{x - 1} - 1} = 1$

Step by step solution

Step 1. Given information

The given limit $\lim_{x \to 1} \frac{x - 1}{e^{x - 1} - 1}$

Step 2. Using L’Hopital’s rule find the value of given limit

The limit using L’Hopitals rule is given below:

$\lim_{x \to 1} \frac{x - 1}{e^{x - 1} - 1} = \lim_{x \to 1} \frac{1 - 0}{e^{x - 1} (1 - 0) - 0} [u \sin g L' H o p i t a l s r u l e] = \lim_{x \to 1} \frac{1}{e^{x - 1}} = \frac{1}{e^{1 - 1}} = \frac{1}{e^{0}} = \frac{1}{1} = 1$

Therefore,the value of liimit $1$
