Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1 cos x. cosec x = 1 sin x cot x = 1 = cos x tan x sin x. Note, sec x is not the same as cos-1 x (sometimes written as arccos x).

2025年3月28日 · cotangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is cot A = length of side adjacent to angle A/ length of side opposite angle A. The other five trigonometric functions are sine (sin), cosine …

首先说cot. 我估计部分高中生应该学过cot。它叫 余切 ，和tan互为倒数。所以，在直角三角形里，tan是对边/邻边，那cot自然是邻边/对边了. 其次是sec，它叫 正割. 类似地，cos和sec互为倒数，直角三角形里是斜边/邻边

The cotangent is one of the trigonometric ratios and is defined as cot x = (adjacent side)/(opposite side) for any angle x in a right-angled triangle.

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used.

Csc sec cot are the three trigonometric functions cosecant, secant, and cotangent respectively. Csc sec cot are based on the other three trigonometric functions sin, cos, and tan, respectively.

divided by the length of the side opposite the angle in a right-angled triangle. Illustrated definition of Cot: The short name for cotangent. It is the length of the adjacent sidebrdivided by the length of the side opposite...

2024年5月21日 · Welcome to Omni's cotangent calculator, where we'll study the cot trig function and its properties. Arguably, among all the trigonometric functions, it is not the most famous or the most used. Nevertheless, you can still come across cot x (or cot(x)) in textbooks, so it might be useful to learn how to find the cotangent. Fortunately, you have ...

Cot is a trigonometric function that is the reciprocal of the tangent function. The cot function is defined as the ratio of the adjacent side of a right triangle to its opposite side. Mathematically, it is expressed as: cot ? = adjacent side / opposite side. where ? is the angle between the adjacent and opposite sides of the triangle.

Cotangent Formulas requires the study of a tangent as it's the reciprocal of Tangent. Study more about its definition and solved questions for better understanding at BYJU'S.
