Cos 300
w Did you estimate 300 degrees from the pocket calculator? 3
The reference angle of 300 degrees will be 60.
With a calculator, you should know that a 60 degree cosine is 1/2. as well as
Since the cosine in Quadrant 4 is 300 degrees and the cosine in Quadrant 4 is positive, the cosine of 300 is also 1/2.

cos 300 is in the fourth quadrant, which means the answer is yes.
Subtract the maximum angle from this quadrant, which is 360 degrees.
cos (360300) = cos 60 degrees
cos 60 degrees = 0.5 or 1/2
cos 300 = cos (270 + 30) = sin 30 = 1/2 and cos is positive in the fourth quadrant.
cos (300º) is equal to cos (300ºº 360º) = cos (60ºº).
The cosine property as a uniform function states that cos (x) = cos (x), then cos (60à š) = cos (60à š), which is obviously equal to 1/2 (you have your unit Know the circle!)
