•You can use the replay function in the CMPLX Mode.
Since complex numbers are stored in replay memory in
the CMPLX Mode, however, more memory than normal
is used up.

k Absolute Value and Argument
Calculation
Supposing the imaginary number expressed by the
rectangular form
z = a + bi is represented as a point in the
Gaussian plane, you can determine the absolute value (r)
and argument (
) of the complex number. The polar form
is
r⬔
.
• Example 1: To determine the absolute value (
r) and
argument (
) of 3+4i (Angle unit: Deg)
