Secant Function: sec (θ) = Hypotenuse / Adjacent. Cotangent Function: cot (θ) = Adjacent / Opposite. sin (θ) = 2/4, and csc (θ) = 4/2. Because of all that we can say: And the other way around: And we also have: Heaps more Trigonometric Identities for you! For the next trigonometric identities we start with Pythagoras' Theorem:

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).

Since csc sec cot are the reciprocals of sin, cos, tan, respectively, they are also called the reciprocal trigonometric functions. In this article, we will explore the concept of csc sec cot and discuss their domain and range, formulas and plot the graphs.

2025年2月24日 · There are six trigonometric functions, of which sine, cosine, and tangent functions are basic functions, while secant (sec), cosecant (cosec or csc), and cotangent (cot) are derived from the three basic functions.

2017年5月29日 · Cot and Cosec The diagrams above show three triangles relating trigonometrical functions. The first one should be familiar to you from the definition of sine and cosine.

2023年4月19日 · A: The formula for sec is: sec(x) = hypotenuse/adjacent, where x is the angle adjacent to the side whose length is the “adjacent” and the hypotenuse is the longest side of the right-angled triangle.

2021年1月26日 · Summary Secant (sec) is the reciprocal of cosine (cos): Cosecant (cosec) is the reciprocal of sin: Cotangent (cot) is the reciprocal of tan: Recall, in case of a right angle triangle if we are given one length and one angle and we have to find a missing length or if we need to find a ...
