This document discusses key concepts related to the unit circle and circular functions including the initial and terminal arms/sides of an angle, standard position, reference angles, and coterminal angles. Specifically, it defines an angle's initial and terminal arms, notes that the initial arm should lay on the x-axis in standard position, gives examples of reference and coterminal angles, and asks to determine coterminal angles within a given range.

- 1. Unit Circle / Circular Functions terminal arm/ side initial arm/ side Standard Position of Initial arm lays on the x-axis the origin
- 2. e) = 2 f) = -3.5
- 3. Acute angle formed between the terminal arm of an angle and the nearest x-axis. Reference Angle
- 4. Coterminal Angles angles which share the same terminal side/ arm ex. Give two coterminal angles for 30 There are infinitely many coterminal angles. ex. Determine the measures of angles that are coterminal with 85o for -400o≤ ≤400o
