In our first meeting, we explored what happened when the parameters of a standard-form quadratic function were varied. The effects of //a// and //c// are commonly known, but what happens when //b// changes is less known. Here is the document we used in our first meeting. Here is a clean version of the file in case you want to use it in your classroom.
 * Quadratic Exploration**

(Thanks to Lin McMullin for the idea in this lesson.) Here is the Smart Notebook file and a pdf version  of the unified approach to solving all triangles once a CAS is available. Because the Nspire CAS sometimes has difficulties solving these equations, I used the [|Wolfram Alpha site] for a more robust (and free!) online CAS.
 * The LoS & LoC are //obsolete//!**
