|
* Calculate the cosecant of a value, defined as `csc(x) = 1/sin(x)`.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.csc(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.csc(2) // returns number 1.099750170294617
|
|
* 1 / math.sin(2) // returns number 1.099750170294617
