3. Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers), and explain why the rectangular and polar forms of a given complex number represent the same number.

[MA2019] PRE-19 (9-12) 4 :
4. Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of this representation for computation.

Example: (-1+ √3i)3=8 because (-1+ √3i) has modulus 2 and argument 120o.
Subject: Mathematics (9 - 12)
Title: Precalculus and Advanced Topics Module 1, Topic B: Complex Number Operations as Transformations

Description:

In Topic B, students develop an understanding that when complex numbers are considered points in the Cartesian plane, complex number multiplication has the geometric effect of a rotation followed by dilations in the complex plane.
