Question

A vector has a magnitude of 12 and a direction of 80°. How do you write the vector in terms of unit vectors?

Answer 1

`12< cos 80^o, sin 80^o >`

Explanation:

The vector is `v=12< cos 80^o, sin 80^o >`, where

`|v|=12` and the unit vector in the direction of `v` is

`1/12v=< cos 80^o, sin 80^o >`
