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=(y)/(x)`

From the given vector x and y are:

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