* Calculate the inverse sine of a value.

* Examples:
*
* math.asin(0.5) // returns number 0.5235987755982989
* math.asin(math.sin(1.5)) // returns number ~1.5
*
* math.asin(2) // returns Complex 1.5707963267948966 -1.3169578969248166 i
*
* See also:
*
* sin, atan, acos
*
* @param {number | BigNumber | Complex | Array | Matrix} x Function input
* @return {number | BigNumber | Complex | Array | Matrix} The arc sine of x
