Unit 3, Day 14

Agenda

1. Number talk: Graph Talks — one wave, four descriptions
2. Random groups — predict then check: $2\sin x$, $\sin (2x)$, $\sin (x-30^{\circ })$, $\sin x+3$
3. Consolidate: the same $a$, $k$, $d$, $c$ — and why a larger $k$ makes a SHORTER period
4. Check your understanding: Sinusoidal Functions Practice

Things to do before our next class

• Finish the practice set.
