What is Arccsc?
Arccsc (arc cosecant) is the inverse of the cosecant function: given a value x, it returns the angle θ such that csc(θ) = x. It is computed as arccsc(x) = arcsin(1/x).
The result is in the interval [−90°, 0°) ∪ (0°, 90°]. Examples: arccsc(1) = 90°, arccsc(2) = 30°, arccsc(−1) = −90°.
Domain: x ≤ −1 or x ≥ 1. Values between −1 and 1 (exclusive) have no real arccsc.
