WebCalculate cos(210)° Determine quadrant: Since 180 270 degrees it is located in Quadrant III tan is positive. Determine angle type: 210 > 90°, so it is obtuse cos(210) = -√ 3 /2 Excel or Google Sheets formula: =COS(RADIANS(210)) 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. …

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. WebWe are here to assist you with your math questions.
