Secant -- from Wolfram MathWorld
where is the cosine.The secant is implemented in the Wolfram Language as Sec[z].. Note that the secant does not appear to be in consistent widespread use in Europe, although it does appear explicitly in various German and Russian handbooks (e.g., Gradshteyn and Ryzhik 2000, p. 43).

Cosecant, Secant, and Cotangent - SparkNotes
In addition to sine, cosine, and tangent, there are three other trigonometric functions you need to know for the Math IIC: cosecant, secant, and cotangent.
Definitions of Tangent, Secant, and Cosecant
Using the alternate definition of sine and cosine as ratios of sides of right triangles, we can give alternate definitions of tangent, secant, cosecant, and cotangent. Oscar Had A Heap Of Apples is a mnemonic to remember that , , and .
Trigonometric functions - Wikipedia
Trigonometric functions are commonly defined as ratios of two sides of a right triangle ... When the series for the tangent and secant functions are expressed in a form in which the denominators are the corresponding factorials, the numerators, called the "tangent numbers" and "secant numbers" respectively, have a combinatorial interpretation: they enumerate alternating permutations of finite ...

Secant - definition of secant by The Free Dictionary
secant - a straight line that intersects a curve at two or more points straight line - a line traced by a point traveling in a constant direction; a line of zero curvature; "the shortest distance between two points is a straight line"
Secant function (sec) - Trigonometry - Math Open Reference
(See also Secant of a circle). 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'. For every trigonometry function such as sec, there is an inverse function that works in reverse. These ...
