# Direction angle of a vector

### Direction angle of a vector

It should be clear by now that a quantity will not be considered a vector quantity if the magnitude or the direction is missing. In this section, we will shift our focus to learn how to indicate the direction of a vector.

#### Lessons

• 1.
Determine the direction angle of the following vectors:
a)
$\vec{p}=$<6, 1>

b)
$\vec{q}=$<-1, 1>

c)

d)

• 2.
Given the magnitude and the direction angle of the following vector, determine its component form

• 3.
Given the magnitude and the direction angle of the following vector, determine its component form

• 4.
