/**
* Calculate the tangent of a value. `tan(x)` is equal to `sin(x) / cos(x)`.
*
* To avoid confusion with the matrix tangent, this function does not apply
* to matrices.
*
* Syntax:
*
* math.tan(x)
*
* Examples:
*
* math.tan(0.5) // returns number 0.5463024898437905
* math.sin(0.5) / math.cos(0.5) // returns number 0.5463024898437905
* math.tan(math.pi / 4) // returns number 1
* math.tan(math.unit(45, 'deg')) // returns number 1
*
* See also:
*
* atan, sin, cos
*
* @param {number | BigNumber | Complex | Unit} x Function input
* @return {number | BigNumber | Complex} Tangent of x
*/
