We have started our unit on Trigonometric Identities in precalculus. Every year is going to be THE YEAR where it all comes together nicely, and the sun comes out and the birdies chirp and the kids embrace their Identities. Yes. It will happen. Chirp. Chirp.
I took some extra time at the start of the unit this year for them to explore instead of me walking them through things and them nodding their heads pretending to understand.
This took most of a block period (2 pages), and it was a nice refresher of a few things:
* proof rules from geometry
* fraction rules for adding/dividing
* exponent rules
Hopefully, the extra time we spent will be worth it in the end as we skip and hop through solving/simplifying various equations/expressions involving trig.
