/**
* Calculate the inverse secant of a value. Defined as `asec(x) = acos(1/x)`.
*
* To avoid confusion with the matrix arcsecant, this function does not
* apply to matrices.
*
* Syntax:
*
* math.asec(x)
*
* Examples:
*
* math.asec(2) // returns 1.0471975511965979
* math.asec(math.sec(1.5)) // returns 1.5
*
* math.asec(0.5) // returns Complex 0 + 1.3169578969248166i
*
* See also:
*
* acos, acot, acsc
*
* @param {number | BigNumber | Complex} x Function input
* @return {number | BigNumber | Complex} The arc secant of x
