# Day 66: Oh What We Can Do With Trig Functions!

Today in Precalculus, I had my students explore what happens when they encounter things like f(x) = |sin x|, g(x) = 2x + 3 cos 6x, and h(x) = (2x + 3)cos 6x.

Their job today was to work with various situations, make conjectures, test them and eventually make a generalization about what they are seeing. Eventually I would like them to connect the equation and what is actually happening graphically.
