Calculates the inverse cosecant of any expression.
ACSC(val)

A scalar, series or table. |
A scalar, series, or table.
acsc(-12..0.01..12);gridhv;griddot
displays the real part of the inverse cosecant from –12 to 12.
acsc(-1)
returns -1.57079633, or -π/2.
acsc(-2..0.1..2)
returns a 41 point complex series.
The inverse cosecant is defined as:
for all complex z. The function is multi-valued and this definition places the branch cut in the complex plane at
For |x| < 1, acsc(x) returns a complex result.
The function calculates in radians unless degrees are specified with the SETDEGREE function.
