  1. I want my trig made easy Objective:Fill in the unit circle using exact values of trig and radian measure

  2. DO NOW • Solve for p: Fill in the unit circle using exact values of trig and radian measure

  3. Trigonometry • 3 things you need to know • Evaluating common angles (the unit circle) • Radians • Solving for sides of triangles Fill in the unit circle using exact values of trig and radian measure

  4. Evaluating Common Angles Fill in the unit circle using exact values of trig and radian measure

  5. Quadrants • Positive or Negative? All Students Take Chemistry I II sin + cos + tan + sin + cos - tan - IV III sin - cos + tan - sin - cos - tan + Fill in the unit circle using exact values of trig and radian measure
