WebExplanation: For cos 2pi/3, the angle 2pi/3 lies between pi/2 and pi (Second Quadrant ). Since cosine function is negative in the second quadrant, thus cos 2pi/3 value = - (1/2) or -0.5. Since the cosine function is a periodic function, we can represent cos 2pi/3 as, cos 2pi/3 = cos (2pi/3 + n × 2pi), n ∈ Z. ⇒ cos 2pi/3 = cos 8pi/3 = cos ... WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75.
