Sec, Cosec and Cot – Mathematics A-Level Revision

Secant (sec) - Trigonometry function (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'. Of the six

What is a second (s or sec)?

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

Secant (sec), cosecant (csc) and cotangent (cot) example

sec=1/cos. cot=1/tan=cos/sin. csc=cosecant, or 1/sin. cot=cotangent, or 1/tan. sec=secant, or 1/cos. Like sin, cos, and tangent, they help you find sides or angles of triangles.
