Since the imaginary and real parts of a complex number are entered and stored separately, you can easily work with or alter either part by itself. y1 Z1 Complex function x1 y2 Z2 x2 (displayed) y imaginary part (displayed) x real part Complex input z or z1and z2 Complex result, z Always enter the imaginary part (the y-part) of a number first. The real portion of the result (zx) is displayed on the second line; the imaginary portion (zy) is displayed on the first line. (For two-number operations, the first complex number, z1, is replicated in the stack's Z and T registers.) Complex Operations Use the complex operations as you do real operations, but precede the operator with { G. To do an operation with one complex number: 1. Enter the complex number z, composed of x + i y, by keying in y x. 2. Select the complex function. 9-2 Operations with Complex Numbers
