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

6 天之前 · cosecant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is csc A = length of hypotenuse / length of side opposite angle A. (The other five trigonometric functions are sine [sin], cosine [cos], tangent [tan], secant [sec], and cotangent [cot].

一.前言 本篇文章介绍的内容是高考不考、大学要会的基础知识，属于高中数学和大学数学的衔接，目标读者主要是参加了高考的同学 因为看到网上的内容相对零散，所以我觉得有必要作一个整合，并且希望在尽量通俗的讲…

Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

Csc sec cot are trigonometric functions named as, cosecant secant and cotangent, respectively. Csc sec cot are the reciprocal functions of sin cos tan, respectively. What are Csc Sec Cot Formulas? The formulas of csc sec cot are as follows: csc x = Hypotenuse / Perpendicular (OR) Hypotenuse / Opposite Side

余割（Cosecant， csc {\displaystyle \csc} ）是三角函数的一种。 它的定义域不是整个实数集，值域是绝对值大于等于1的实数。 它是周期函数，其最小正周期为 2 π {\displaystyle 2\pi} 。

Csc is the cosecant function, which is one of the basic functions encountered in trigonometry. It is defined as the reciprocal of the sine function: . It is defined for real numbers by letting be a radian angle measured counterclockwise from the axis along the circumference of the unit circle.

Illustrated definition of Cosecant: In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length...

The classical definition of the cosecant function for real arguments is: "the cosecant of an angle in a right‐angle triangle is the ratio of the length of the hypotenuse to the length of the opposite leg." This description of is valid for when this triangle is nondegenerate.

3 天之前 · The cosecant cscz is the function defined by cscz = 1/(sinz) (1) = (2i)/(e^(iz)-e^(-iz)), (2) where sinz is the sine. The cosecant is implemented in the Wolfram Language as Csc[z]. The notation cosecz is sometimes also used (Gellert et al. …
