Answer:
Step-by-step explanation:
Remove full rotations of [tex]2\pi[/tex] until the angle is between 0 and [tex]2\pi[/tex].
[tex]cos(\frac{\pi }{3} )[/tex]
The exact value of [tex]cos(\frac{\pi }{3})[/tex] is [tex]\frac{1}{2}[/tex].
[tex]\frac{1}{2}[/tex]
The result can be shown in multiple forms.
Exact Form:
[tex]\frac{1}{2}[/tex]
Decimal Form:
[tex]0.5[/tex]
Vocabulary:
Rotation
