ANSWER
[tex]\cos (\pi/3)\text{ = }\frac{\sqrt[]{3}}{2}[/tex]
EXPLANATION
We need to find the value of cos(π/3) using special right triangle.
First, we have to simplify π/3 (in radian)
π radians is equivalent to 180 degrees.
This means that π/3 is equal to:
180/3 = 60 degrees
We need to draw the special right triangle for 60 degrees:
The trigonometric ratio for cosine is:
[tex]\cos \Theta\text{ = }\frac{adjacent}{hypotenuse}[/tex]
So, using that, we have that the value of cos(π/3) is:
[tex]\cos \mleft(\pi/3\mright)\text{ = }\frac{\sqrt[]{3}}{2}[/tex]
