A. Yes. The arithmetic operations on complex numbers can be easily managed using the Calculators.
These kinds of calculations, which are used often in physical and technical fields, are explained here as a supplement to the calculator manual.
The complex numbers can be represented in two different forms:
Rectangular or Cartesian form: z = x+iy (In some notation j may be used instead of i.)
Polar or Phasor form: z = r<θ or z = |z|e^θi. (In some notations φ may be used instead of θ.)
