ACSCH _ _ _ _ _ _ _ _ _ _ _ _ operator
The acsch operator returns the hyperbolic arccosecant of its argument.
<expression> may be any scalar REDUCE expression, not an array, matrix or vector expression. <simple\_expression> must be a single identifier or begin with a prefix operator name.
acsch(ab); ACSCH(AB) acsch 15; ACSCH(15) df(acsch(x*y),x); 2 2 -SQRT(X *Y + 1) ---------------- 2 2 X*(X *Y + 1) on rounded; res := acsch(3); RES := 0.327450150237
An explicit numeric value is not given unless the switch round ed is on and the argument has an absolute numeric value less than or equal to 1.
