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
¹ c
.
To do an operation with one complex number:
1. Enter the complex number z, composed of x + i y, by keying in y
Ï
x.
2. Select the complex function.
