Lessons for F.TF.A.4
Graphing sine and cosinePlotting the height of the terminal point against the angle to see where the wave shape comes from.Lesson
Periodicity and the periodicity identitiesAdding a full turn returns to the same point, so every trig value repeats after one revolution.Lesson
Unit circle symmetry and even-odd identitiesReflecting a terminal point across an axis or the origin changes only the signs of its coordinates.Lesson
