  • Method and apparatus for determining the exponential powers of "i"
    Patent number: 5717193
    Abstract: The present invention provides methods and apparatus for readily determining the value of the imaginary number "i" raised to different exponential powers. Calculations pertaining to the imaginary "i" are commonly encountered in engineering, mathematical and scientific calculations and analysis. In accordance with the present invention, the value of "i" raised to any magnitude of exponential power is readily determined based upon the values of the "ones" and "tens" place of the exponent, including whether the "tens" value is an even or odd integer. Different apparatus are provided for readily calculating the value of the imaginary number "i" for any natural number of exponential power.
