Final answer:
The value of cos(pi/3) is 1/2.
Step-by-step explanation:
In trigonometry, the cosine function relates the lengths of the adjacent side to the hypotenuse in a right triangle. To find the value of cos(pi/3), we can use the exact value of cosine for this angle.
Since pi/3 is the same as 60 degrees, we know that cos(pi/3) is equal to 1/2. Therefore, the value of cos(pi/3) is 1/2.
