Secant | Definition, Formulas, & Facts | Britannica
secant, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is sec A = length of hypotenuse / length of side adjacent angle A. (The other five trigonometric functions are sine [sin], cosine [cos], tangent [tan], cosecant [csc], and cotangent [cot].)
Secant - Wikipedia
Secant is a term in mathematics derived from the Latin secare ("to cut"). It may refer to: a secant line, in geometry; the secant variety, in algebraic geometry; secant (trigonometry) (Latin: secans), the multiplicative inverse (or reciprocal) trigonometric function of the cosine
Trigonometric functions - Wikipedia
Conventionally, 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.
Secant line - Wikipedia
In geometry, a secant is a line that intersects a curve at a minimum of two distinct points. [1] The word secant comes from the Latin word secare, meaning to cut. [2] In the case of a circle, a secant intersects the circle at exactly two points.
Secant function (sec) - Trigonometry - Math Open Reference
In 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.
Secant Function - Formula, Graph, Domain and Range ... - Cuemath
The secant function or sec function can be defined as the ratio of the length of the hypotenuse to that of the length of the base in a right-angled triangle. What is Secant in terms of Cos? Secant function in terms of cos is written as sec x = 1 / cos x. Where is the Secant Function Not Defined?
Secant Line -- from Wolfram MathWorld
A secant line, also simply called a secant, is a line passing through two points of a curve. As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line.
Secant of a Circle- Definition, Formula and Properties - BYJU'S
A secant is an extension of a chord in a circle which is a straight line segment of which the endpoints lie on the circle. If the same chord passes through the centre of the circle, then it is a diameter.
Secant Formula – Concept, Formulae, Solved Examples
Secant is one of the six basic trigonometric ratios and its formula is secant(θ) = hypotenuse/base, it is also represented as, sec(θ). It is the inverse(reciprocal) ratio of the cosine function and is the ratio of the Hypotenus and Base sides in a right-angle triangle.
Secant in Trigonometry Explained Simply - Andrea Minini
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 OC that starts at the origin O, passes through point P, and intersects the tangent at point C.
