Using these numbers as exponents is defined in terms of a reciprocal.
The tangent function gives these numbers when its input is in the 2nd or 4th quadrant. Using these numbers as exponents is defined in terms of a reciprocal. The absolute value function changes them. Defining their square roots requires (*) imaginary numbers. Integers that are not natural numbers are either zero or one of these. For 10 points, name these numbers that are less than zero.
