Unit 3, Day 12

Agenda

1. Number talk: True or False — claims about $\sin x$
2. Random groups — unwrap the unit circle: plot the sine ratio for every angle from $0°$ to $360°$
3. Consolidate: Sinusoidal Functions — the wave finally gets a name
4. Check your understanding: Sinusoidal Functions Practice

Things to do before our next class

• Journal: why the Ferris wheel graph and today’s unwrapped circle drew the same shape.
