WebExplanation: For cot 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant ). 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.

WebDetailed step by step solution for cot(-(5pi)/6) WebDetailed step by step solution for cot((3pi)/2)-cot(pi/6) WebThe value of cot 5pi/4 can be calculated by constructing an angle of 5π/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 5pi/4 is equal to the x-coordinate (-0.7071) divided by the y-coordinate (-0.7071). ∴ cot 5pi/4 = 1. exercise routine for stationary bike
