+   * 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
