A scalar, series or table. |
A scalar, series, or table.
csch(-10..0.01..10);gridhv;griddot;sety(-10, 10)
displays the hyperbolic cosecant from –10 to 10.
csch(pi)
returns 0.086589538.
csch(-2..0.1..2)
returns a 41 point series.
The hyperbolic cosecant is defined as:
for all complex z.
SETDEGREE and SETRADIAN have no effect on this function because it always operates in radians.
At 0, this function returns ∞. Near 0, it returns a very large real number.
