Question

Find the direction angle of v for the following vector.v=−6i−2jWhat is the direction angle of v?

Answer 1

Given:

v is the given vector.

$v=-6i-2j$

To find:

Find the direction angle of v.

Formula to find the direction:

$\tan \theta=\frac{y}{x}$

From the given vector x and y are:

$x=-6\text{ \& y=-2}$$\begin{gathered} \tan \theta=\frac{-2}{-6} \\ \theta=\tan ^{-1}(\frac{1}{3}) \\ \theta=18.4\degree \end{gathered}$
