Complex Number Arithmetic

Use the application below to investigate the behaviour of Complex Numbers. Try to consider - a) How to the real and imaginary parts of arithmetic interact; i.e. FOIL is used to multiply brackets b) How do the modulus (length) and argument (angle) of complex numbers get combined Use the mode slider to change the operations:
  • Addition
  • Subtraction
  • Modulus and Argument
  • Multiplication
  • Conjugate
  • Division (May be simpler to consider how you remove SURDS from denominators
  • Square roots of complex numbers
