Mar 31, 2025 · 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].

Cosecant (csc) - Trigonometry function. 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'.

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.

In this section we define sine, cosine and tangent, as well as the reciproacla ratios, csc, sec and cot.

These lessons, with video lessons, examples and step-by-step solutions, help Algebra 2 students to learn about the trigonometric function: Sin, Cos, Tan and the reciprocal trigonometric functions Csc, Sec and Cot.

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 cosecant function \( csc (\theta) \) is defined as \( \csc(\theta) = \dfrac{r}{y} \) , where \( r \) is the distance from O to M and is given by \( r = \sqrt{x^2+y^2} \).

The cosecant function (usually abbreviated as csc) is the reciprocal function of the sine function. As with the other trigonometric functions in modern use, the cosecant function was certainly known to Arab scholars, and tables of cosecant values are known to have been in existence by the tenth century CE.

Cosecant is one of the six trigonometric ratios which is also denoted as cosec or csc. The cosecant formula is given by the length of the hypotenuse divided by the length of the opposite side in a right triangle.

The trigonometric function cosecant abbreviated as csc, is among the less frequently discussed but equally significant trigonometric functions. The csc function is defined as the reciprocal of the sine function. In other words, csc(θ) = 1 / sin(θ), where θ …
