Cot-12+cot-18
Web6° is 36-30, 12° is 30−18, 24° is 54−30, and 42° is 60−18; so we use the subtraction formulas for sine and cosine. n × π/60 3° is 18−15, 21° is 36−15, 33° is 18+15, and 39° is 54−15, so we use the subtraction (or addition) formulas for sine and cosine.

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. WebThe cotangent function is used in the ASA triangle rule (angle-side-angle). Other than that, it has not had many practical applications since calculators became common, so you should rarely come across it. Above: the cot …
