WebIn Trigonometry, different types of problems can be solved using trigonometry formulas. These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc. Some formulas including the sign of ratios in different quadrants, involving co-function identities (shifting angles), sum & difference … WebOct 6, 2024 · In Figure 7.4.1, the cotangent of angle t is equal to cost sin t = x y, y ≠ 0. The cotangent function is abbreviated as cot. The cosecant function is the reciprocal of the sine function. In Figure 7.4.1, the cosecant of angle t is equal to 1 sin t = 1 y, y ≠ 0. The cosecant function is abbreviated as csc.
