instead.) In polar form, the magnitude and phase angle are separated

by a comma and angle sign (¿). (The angle is based on the current

angle mode: Degrees, Radians, or Grads.) Regardless of how complex

numbers are displayed, the HP 48 stores them internally in rectangular

form.

Entering Complex Numbers

You can enter complex numbers using either rectangular coordinates

or polar coordinates.

To enter a complex number:

■ To enter rectangular coordinates, press S)0> enter the

coordinates separated by fSPC) or

S)0,

and press (ENTER).

■ To enter polar coordinates, press S)0> enter the coordinates

The internal rectangular representation of all complex numbers has

the following effects op polar numbers:

■ 0 is normalized to the range ±180° (±7r radians, ±200 grads).

■ If you key in a negative r, the value is made positive, and 0 is

increased by 180° and normalized.

■ If you key in an r of 0, 6 is also reduced to 0.
