What is the exact value of cos 10pi 3?
-0.5
The value of cos 10pi/3 is -0.5. Cos 10pi/3 radians in degrees is written as cos ((10π/3) × 180°/π), i.e., cos (600°).
How do you find the exact value of cos 5pi 3?
The value of cos 5pi/3 can be calculated by constructing an angle of 5π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (0.5, -0.866) on the unit circle. The value of cos 5pi/3 is equal to the x-coordinate (0.5). ∴ cos 5pi/3 = 0.5.
