  4. (6-1) Identify the initial position of an angle within a unit circle

  5. (6-1) Know that positive angles rotate counter-clockwise within the unit circle

  6. (6-1) Know that negative angles rotate clockwise within the unit circle

  7. (6-1) Compute arc length (p.477)

  8. (6-1) Compute area of a sector of a circle (p.478)

  9. (6-2) Know the right triangle definitions of the six trig ratios (p.483)

  10. (6-2) Solve a right triangle for all three sides and all three angles, using the trig ratios and/or the Pythagorean Theorem\

  11. (6-2) Know the trig ratios for common angles as in Table-1 on p.485

  12. (6-2) Use the trig ratios for common angles to exact value of a trig expression (e.g., #23, 25, 27 in the homework)

  13. (6-2) Use trig ratios to measure an inaccessible distance (e.g., height of building, distance across river, etc.)

  14. (6-3) Identify the quadrant in which an angle terminates given the values of two trig functions of that angle

  15. (6-3) Determine the value of the other five trig functions given certain information like one trig value

  16. (6-3) Calculate the area of triangle using the formula on p.500

  18. (6-4) Use the Law of Sines to solve a triangle

  19. (6-4) Know when the Law of Sines leads to two possible solutions (the ambiguous case)

  20. (6-4) Calculate the two possible solutions of a triangle in the ambiguous case

  21. (6-4) Know when the Law of Sines leads to no possible solution (i.e., the triangle cannot exist)

  22. (6-4) Use the Law of Sines to solve applied surveying problems

  23. (6-5) Use the Law of Cosines to solve a triangle

  24. (6-5) Decide when to use the Law of Cosines over the Law of Sines, and vice versa, when solving a triangle

  25. (6-5) Use the Law of Cosines to solve an applied surveying or navigation problem
