WebExplanation: For cot 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since cotangent function is negative in the second quadrant, thus cot 120° value = - (1/√3) or -0.5773502. . . Since the cotangent function is a periodic function, we can represent cot 120° as, cot 120 degrees = cot (120° + n × 180°), n ∈ Z.

WebApr 19, 2015 · There exists 4 trigonometric quadrants. All, Sine, Tan & Cos . 570 degrees turns out to land in the tan quadrant, therefore cos(570) has to be negative. 90 (all) + 90 (sin) + 90 (tan) + 90 (cos) + 90 (all) + 90 (sin) + 30 (tan) makes 570 degrees and the last turn helps us land in the tan quadrant. Remember that 90+90+90+90+90+90+30=570. … WebJan 18, 2024 · Use the cosecant formula: cscθ = Hypo. Opp. c s c θ = H y p o. O p p. and substitute for 30 degrees first: csc(30) = 2∗a a c s c ( 30) = 2 ∗ a a where a cancels as a … WebStep 1: Plug the angle value, in degrees, in the formula above: radian measure = (255 × π)/180. Step 2: Rearrange the terms: radian measure = π × 255/180. Step 3: Reduce or simplify the fraction of π if necessary. Calculating the gcd of 255 and 180 [gcd (255,180)], we've found that it equals 15. binswanger encephalopathy
