Bookmark or Share- Sec, Cosec and Cot – Mathematics A-Level RevisionSecant, 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 written as arccos x).
- Csc Sec Cot - Formula, Table, Domain, Graph, Examples - CuemathIt is defined as the ratio of the hypotenuse and opposite side of the angle in a right-angled triangle. Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. Secant Function
- Cosecant - Formula, Graph, Domain, Range | Cosecant Function - CuemathCosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.
- 2.2: Graphs of the Secant and Cosecant FunctionsGraphing Variations of \(y = \sec x\) and \(y= \csc x\) For shifted, compressed, and/or stretched versions of the secant and cosecant functions, we locate the vertical asymptotes and also evaluate the functions for a few points (specifically the local extrema).
- 4. Graphs of tan, cot, sec and csc - Interactive MathematicsWe learn why graphs of tan, cot, sec and cosec have a periodic gap in them (also known as a discontinuity). We learn how to sketch the graphs.
