Warm up involved finding all possible missing sides and/or angles in 2 right triangles, one involving sin/cos/tan trigonometry and the other requiring some inverse trigonometry. Briefly touched on the "trig stack" hw and checked answers of those who attempted it, then did two more 3 act math tasks relating to trigonometry in applied contexts. Then looked at a few more in-depth trig questions really decoding the meaning of sine, cosine, and tangent. Passed out practice assessments.
