Hi, as Pi = 180° in the trigonometric

Then , pi/3 = 180°/3

Pi/3 = 60°

Then,

Cos ( 60° ) = 1 / 2

Because, Sen(30) = Cos(60)

And as Sen(30) = 0.5 = 1/2

Then, Cos(60°) = 0.5
The question that you have is in radians.
To convert radians to degrees, you multiply the number by [tex] \frac{180}{ \pi } [/tex].
Therefore, the question in degrees is:
