Trigonometric Identities - Math is Fun
WEBThe three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent.
Trigonometric functions - Wikipedia
WEBConventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent.

Trigonometric Identities (List of Trigonometric Identities - BYJU'S
WEBAll the trigonometric identities are based on the six trigonometric ratios. They are sine, cosine, tangent, cosecant, secant, and cotangent. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side.
What does sec x equal in terms of sin, cos, and/or tan?
WEBSep 15, 2015 · sec alpha=1/cos alpha This comes straight from the definition. Secans is defined as inverse of cosine.
Secant in Trigonometry Explained Simply - Andrea Minini
WEBIn trigonometry, the secant is a function that associates an angle α with the reciprocal of the cosine. It is denoted as sec and is expressed as: secα = 1 cosα. Geometrically, the secant (OB) is the point where the line (r), which is tangent at point P on the unit circle, intersects the x-axis. The secant can also be seen as the line segment ...
Secant function (sec) - Trigonometry - Math Open Reference
WEBIn a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used.
Trigonometric Ratios (Definition, Formulas, Examples) - BYJU'S
WEBThe six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
Secant Formula - What is Secant Formula?, Examples - Cuemath
WEBWhen the length of the hypotenuse is divided by the length of the adjacent side, it gives the secant of the angle, of the right-angled triangle. Secant is denoted as 'sec'. Secant formula is derived out from the inverse cosine (cos) ratio.
