+   * Calculate the secant of a value, defined as `sec(x) = 1/cos(x)`.

+   * To avoid confusion with the matrix secant, this function does not

+   * Syntax:
+   *
+   *    math.sec(x)
+   *
+   * Examples:
+   *
+   *    math.sec(2)      // returns number -2.4029979617223822
+   *    1 / math.cos(2)  // returns number -2.4029979617223822
