In these videos I show you how to derive the modulus – argument of complex numbers from an Argand Diagram. We progress from plotting complex numbers on an Argand Diagram to converting between the x + iy and modulus – argument.
Future lessons go on to performing calculations with complex numbers in modulus-argument form and proving De’ Moivres theorem.
