Objective #1: Understand the vocabulary "reference angle" and "co-terminal angle" and evaluate sine, cosine, and tangent of 30°, 60°, and 45° angles. Examples: 1. Are 125° and -595° co-terminal angles? Why? Can you explain the process for finding coterminal angles? 2. Evaluate cos(45°) Videos and Practice: Objective #2: Evaluate sine, cosine, and tangent of multiples of 30°, 60°, and 45° angles. Examples: 1. Evaluate sin(120°) Videos and Practice: Objective #3: Convert between radian and degree measure. Examples: 1. Write 120° in radians. 2. How many degrees is 3π radians? Videos and Practice: |
