  /**
   * Calculate the inverse cotangent of a value, defined as `acot(x) = atan(1/x)`.
   *
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.acot(x)
   *
   * Examples:
   *
   *    math.acot(0.5)           // returns number 0.4636476090008061
   *    math.acot(math.cot(1.5)) // returns number 1.5
   *
   *    math.acot(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
   *
