|
* Calculate the secant of a value, defined as `sec(x) = 1/cos(x)`.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.sec(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.sec(2) // returns number -2.4029979617223822
|
|
* 1 / math.cos(2) // returns number -2.4029979617223822
