Chapter 1: Q. 84 (page 136)

Use the Squeeze Theorem to find each of the limits in Exercises. Explain exactly how the Squeeze Theorem applies in each case.
$\lim_{x 鈫� 1} {(x - 1)}^{2} c o s \frac{1}{x - 1}$

Short Answer

Expert verified

The limit of the equation $\lim_{x 鈫� 1} {(x - 1)}^{2} c o s \frac{1}{x - 1}$ is 0

Step by step solution

Step 1. Given Information:

$\lim_{x 鈫� 1} {(x - 1)}^{2} c o s \frac{1}{x - 1}$

Step 2. Applying Squeeze theorem on the limit:

By applying the Squeeze theorem;
