Romancing the Graph: A Valentine's Date With Polar Functions

When: Tuesday, Feb. 6, 2024 | 7 p.m. Central time
Technology: TI-84 Plus family, TI‑Nspire™ CX technology
Presenters: Rachael Gorsuch, Steve Phelps

Get ready to fall in love with mathematics!

We'll delve into the heart of polar coordinates and show how love isn't just in the air, but also in the math. We'll explore the transformation of equations from rectangular to polar form, a key skill in the AP® Precalculus curriculum. Plus, we'll use the TI-84 Plus CE and TI‑Nspire™ CX II graphing calculators to graph heart-shaped polar functions, demonstrating the symmetry and periodicity of these lovely curves.

Presenters will focus on using the TI-84 Plus CE graphing calculator and will also highlight concepts using TI-Nspire™ CX II technology.
