The cosine of Ø is: [tex]\frac{1}{2}[/tex]
The ordered pair of a unit circle is represented as:
[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]
The given parameters can be represented as:
[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]
Recall that:
[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]
Compare the above representation to:
[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]
This means:
[tex]\cos(\theta) = \frac{1}{2}[/tex] and [tex]\sin(\theta) = \frac{\sqrt 3}{2}[/tex]
