A complex number has real and imaginary components that identify a point
in the complex plane. These components are measured along the real and
imaginary axes, which are similar to the x and y axes in the real plane.
The point can be expressed in
rectangular form or in either of
two polar forms.
The

As shown below, the form that you can enter depends on the current Angle
mode.
You can use the form: When the Angle mode setting is:
