Abbreviations: acsc, arccsc

 Figure 1: Arccosecant

An arccosecant is an angle whose cosecant is a particular value. Arccosecant is often abbreviated as csc-1. The arccosecant is a trigonometric function. The arccosecant is the functional inverse of the cosecant. If hypotenuse/opposite = csc(θ) then csc-1(hypotenuse/opposite) = θ. Arccosecant is written arccsc or csc-1.

Definition: y = csc-1 x if and only if x = csc y.
