The classical definition of the cosecant function for real arguments is: "the cosecant of an angle Oct 27, 2026 · The cosecant cscz is the function defined by cscz = 1/(sinz) (1) = (2i)/(e^(iz)-e^(-iz)), (2) where sinz is the sine and sinz!=0. It was widely used by L. Each of these six trigonometric functions has a corresponding inverse function and has an analog among the hyperbolic functions. Jul 23, 2025 · Cosecant is one of the six basic trigonometric ratios and its formula is cosecant (θ) = hypotenuse/opposite, it is also represented as, csc (θ). von Lauchen Rheticus (1596) and E. Find out the relationship between cosecant and sine, and see solved examples and FAQs on cosecant. They are essential for solving a wide range of problems in mathematics, physics, engineering, and other fields. Some of the most important trigonometric formulas are: Introduction to the Cosecant Function Defining the cosecant function The cosecant function is an old mathematical function. Since it is the reciprocal of sine, we can write the cosecant formula as cosec x = 1 / sin x. Note that the cosecant does not appear to be in consistent widespread use in Europe . The cosecant formula is given by the length of the hypotenuse divided by the length of the opposite side in a right triangle. It is abbreviated as csc x or cosec x, where x is the angle. 222; Gradshteyn and Ryzhik 2000, p. xxix). The cosecant function is the reciprocal of the trigonometric function sine. Olivier, Wait, and Jones (1881). Cosecant is one of the six trigonometric ratios which is also denoted as cosec or csc. Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less commonly used. In a right-angled triangle, the cosecant is the ratio of the hypotenuse to the perpendicular. It was mentioned in the works of G. Learn how to calculate cosecant ratio using the formula cosec A = hypotenuse / opposite side. The trigonometric functions most commonly used in modern mathematics are the sine, the cosine, and the tangent functions. It is the inverse (reciprocal) ratio of the sine function and is the ratio of the Hypotenus and Opposite sides in a right-angle triangle. Gunter (around 1620). Learn how to define and calculate the cosecant of an angle using a right triangle and the reciprocal function of the sine. Find out how to use Csc [z] in the Wolfram Language and explore its values, graphs, and identities. J. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. 1989, p. Cosine formulas are derived from various trigonometric formulas. Trigonometry is a branch of mathematics that studies Feb 10, 2026 · Trigonometry formulas are equations that relate the various trigonometric ratios to each other. 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 cosecant function is a trigonometric function and is the reciprocal of the sine function. The oldest definitions of Cosecant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, iscsc A = length of hypotenuse length of side opposite angle A . The cosecant is implemented in the Wolfram Language as Csc[z]. Euler (1748) and T. Find the values of the cosecant for common special angles and practice with exercises. Cosecant is also The cosine formulas are formulas about the cosine function in trigonometry. (The other five trigonometric functions are sine [sin], cosine [cos], tangent [tan], secant [sec], and cotangent [cot]. The notation cosecz is sometimes also used (Gellert et al. Understand the cosine formulas with derivation, examples, and FAQs. (The other five trigonometric functions are sine [sin], cosine [cos], tangent [tan], secant [sec], and cotangent [cot].
