AP® Precalculus Unit 4: Exploring Parameters, Vectors and Matrices

When: Tuesday, Dec. 5, 2023 | 7 p.m. Central time
Technology: TI-84 Plus family, TI‑Nspire™ CX technology
Presenters: Greg Foley, Steve Phelps

How do I graph parametric equations on TI technology? How do I work with vectors and matrices on TI technology?

In this webinar, the presenters will guide you through:

  • Setting up and graphing parametric equations.
  • Connecting parametric equations to particle motion in a plane.
  • Modeling a scenario using parametric equations.
  • Working with vectors.
  • Computing with matrices such as sums, products, inverses and linear transformations of vectors.
  • Showing transition states with matrices to reach a steady state or equilibrium.
Attend this live webinar, and you’ll be entered into a drawing for a free TI graphing calculator. (See drawing rules.)
