|
|
* Calculate the inverse cosecant of a value, defined as `acsc(x) = asin(1/x)`.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.acsc(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.acsc(0.5) // returns number 0.5235987755982989
|
|
* math.acsc(math.csc(1.5)) // returns number ~1.5
|
|
*
|
|
* math.acsc(2) // returns Complex 1.5707963267948966 -1.3169578969248166 i
