- Ensure class understand the relationship between SIN, COS and TAN.
- Be able to use SIN, COS and TAN on a calculator to solve an equation.
- Know that sine and cosine are the same but with a shift in phase.

Plan

10:00 Settle class and outline learning objectives.

10:10 Introduce the functions.

10:20 Interactive demonstration of use of functions.

10:40 Set some example questions.

10:50 Review answers to questions.

10:55 Graph SIN, COS and TAN on computer and lead class in spotting the phase shift with SIN and COS.

- Class kept the pace up.
- Table 2 consistently had difficulty working out when to use SIN vs. COS.
- Would be nice to have an overlay for the last part that can be shifted on screen to show they match.
