This is designed as a second lesson on trig graphs, building on the excellent spaghetti lesson 7... this with the previous lesson gives an excellent foundational understanding of trig graphs, which makes all other lessons much easier. 27 slides.
This lesson goes into a lot of detail to explain different aspects, and so is content/ teacher heavy with 27 slides, but has lots of little activities and lots of custom animation.
This is part of a much larger bundle on trigonometry, which I highly recommend as the lessons are in sequence and do build on each other.
