Chapter 9.4, Problem 4E

To determine

To find:The vector $v$ with initial point P and terminal point Q.

Answer to Problem 4E

The vector $v$ with initial point P and terminal point Qis $\langle 2,-3,3\rangle$ .

Explanation of Solution

Given information:

The pointis $P\left(1,2,-1\right),Q\left(3,-1,2\right)$ .

Calculation:

The vector $v$ is,

$v=\langle x_2-x_1,y_2-y_1,z_2-z_1\rangle$

Substitute the values in above equation.

$\begin{array}{c}v=\langle 3-1,-1-2,2-\left(-1\right)\rangle \\ =\langle 2,-3,3\rangle \end{array}$
