New handheld technologies such as arbitrary relation graphers and dynamic geometry allow for great opportunities to explore unit circle trigonometry. Attendees will experience a new handheld device in the context of four mini-lessons: wrapping functions; when inverses misbehave; the cosine addition formula; and DeMoivre's theorem.
