Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

The line that has length $\tan \theta$ is tangent to the circle, whereas the line that has length $\sec \theta$ is secant to the circle. As far as I can tell, there is no relation whatsoever between, on the one hand, the functions $\tan$ and $\sec$, and on the other hand, tangent and secant lines to ...
WebDivide the equation by cos 2 x. ⇒ sin 2 x cos 2 x + cos 2 x cos 2 x = 1 cos 2 x. Since, sin x cos x = tan x, and 1 cos x = s e c x. ⇒ tan 2 x + 1 = s e c 2 x. rearranging the terms, ⇒ sec 2 x - 1 = tan 2 x. Hence, tan 2 x = sec 2 x - 1 is an identity. Suggest Corrections. Web3 Apr 2024 · trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
