Algebra and geometry of Complex Numbers using TI-Nspire

Summary

In this workshop we will explore how to plot complex numbers using the TI-Npise, and dynamically explore the geometry of addition/subtraction complex numbers, and multiplication/division of complex numbers, which includes multiplying by powers of i. Alongside this, the behaviour of the magnitude and argument of the complex numbers will be explore, which then sets up a geometric explanation for De Moivre’s theorem. If time permits, we will also explore how to plot subsets of the complex plane using TI-Nspire, and apply these techniques to past VCAA questions. TI-NSpire CAS handhelds will be available, or feel free to bring your own laptop or handheld.
