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
