For example, if α = 1400 ° \alpha = 1400\degree α = 1400° , then the coterminal angle in the [ 0 , 360 ° ) [0,360\degree) [ 0 , 360° ) range is 320 ° 320\degree 320° – which is already one example of a positive ...
WebFor cos pi, the angle pi lies on the negative x-axis. Thus, cos pi value = -1 Since the cosine function is a periodic function, we can represent cos pi as, cos pi = cos(pi + n × 2pi), n ∈ Z. ⇒ cos pi = cos 3pi = cos 5pi , and so on. Note: Since, cosine is an even function, the value of cos(-pi) = cos(pi). WebSep 2, 2024 · Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos (60) in a triangle yields 1/2, and sin (60) yields (3^ (1/2))/2. Thus, -pi/3, or -60 degrees would be a …
WebAnswer (1 of 4): pi/3 is in the first quadrant. Each complete 360 degree rotation from the pi/3 position is 2pi which is 6pi/3. Thus 6pi/3 is added to pi/3 for each complete rotation.
