|
|
* Calculate the cotangent of a value. Defined as `cot(x) = 1 / tan(x)`.
|
||
|
|
*
|
||
|
|
* For matrices, the function is evaluated element wise.
|
||
|
|
*
|
||
|
|
* Syntax:
|
||
|
|
*
|
||
|
|
* math.cot(x)
|
||
|
|
*
|
||
|
|
* Examples:
|
||
|
|
*
|
||
|
|
* math.cot(2) // returns number -0.45765755436028577
|
||
|
|
* 1 / math.tan(2) // returns number -0.45765755436028577
