The interval [- π/6, 5π/6] corresponds to one cycle of the graph. The cycle begins with - π/6 and ends with 5π/6 and find the three middle values. Dividing this interval into four equal parts produces the key points. one fourth of cycle is [5π/6 - (- π/6) ]/4 ...

WebAlternatively, if the angle is unknown, but the lengths of the two sides of a right angle triangle are known, calculating the cotangent is just a matter of dividing the adjacent by the opposite side. For example, if in the … WebThe value of cot 3pi/4 can be calculated by constructing an angle of 3π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cot 3pi/4 is equal to the x-coordinate (-0.7071) divided by the y-coordinate (0.7071). ∴ cot 3pi/4 = -1. estate watches scottsdale

Since cotangent function is negative in the second quadrant, thus cot 150° value = -√3 or -1.7320508. . . Since the cotangent function is a periodic function, we can represent cot 150° as, cot 150 degrees = cot (150° + n × 180°), n ∈ Z.
