This document outlines the goals, essential questions, enduring understandings, and products for a trigonometry course. The goals are to explore trigonometry's history, solve real-world problems using trig functions, and simplify functions using identities. Key questions address the functions, history, and use of identities. Students will demonstrate understanding through a review test, timeline, unit circle diagram, and resource wiki. Reflections note rediscovering forgotten concepts and complexity, with a need to further explore applications.
