•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.

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 (
