9–2 Operations with Complex Numbers
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.

Always enter the imaginary part (the y–part) of a number first. The real portion of
the result (z
x
) is displayed on the second line; the imaginary portion (z
y
) is
displayed on the first line. (For two–number operations, the first complex number,
z
1
, 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.
