Many physics problems benefit from the power of complex numbers. To calculate the real part of the following complex expression z=`(1+i)/(1-i)`, Definitions and Formulas. Conic Sections: Parabola and Focus. Most loads in AC systems will have some resistive and some reactive component, so one number is not enough to describe power in these cases. The real and imaginary parts of the Fourier coefficients c k are written in this unusual way for convenience in defining the classic Fourier series. The division of complex numbers with this notation is almost the same: A / B = | z_1| * exp (i_1)/ | z^2| * exp (i)= | z_1/z^2| * exp (i(_1 ^2) ),Rewrite the result as: A / B = | z_1 / z^2| and arg (A / B) = _1 ^2. Hence, either portion could be 0. Discount calculator uses a product's original price and discount percentage to find the final price and the amount you save. Real part: x = Re z = -1.
