Chapter 11: Q. 43 (page 860)

Evaluate the limits in Exercises 42–45.
$\underset{t \to π}{l i m} (\sin t, \cos t, s e c t)$

Short Answer

Expert verified

The evaluation of the limit $\underset{t \to π}{l i m} (\sin t, \cos t, s e c t)$ is $(0, - 1, - 1)$ .

Step by step solution

Step 1. Given Information.

The function:

$\underset{t \to π}{l i m} (\sin t, \cos t, s e c t)$

Step 2. Apply the limits.

By applying the limit and solving,

$\underset{t \to π}{l i m} (\sin t, \cos t, s e c t) = \underset{t \to π}{l i m} (\sin t) i + \underset{t \to π}{l i m} (\cos t) j + \underset{t \to π}{l i m} (s e c t) k = sinπ i + cosπ j + s e c πk = 0 i - j - k = (0, - 1, - 1)$
