1. Trigonometry Review Game

2. Do not use a calculator on any of these questions until specified otherwise.

3. Sin(45) = ? (1 min)

4. Answer: Sin(45) = sqrt(2)/2

5. cos(45) = ? (15 secs)

6. Answer cos(45) = sqrt(2)/2 Sin(45) = cos(45) since they are cofunctions.

7. cos(60) = ? (1 min)

8. answer cos(60) = 1/2

9. tan(60) = ? (1 min)

10. answer tan(60) = sqrt(3)

11. tan(90) = ? (1 min)

12. answer tan(90) = undefined

13. sin(0) = ? (1 min)

14. answer sin(0) = 0

15. Find the exact value: sin 2 60 + cos 60 =

16. answer sin 2 60 + cos 60 = 5/4

17. csc 2 (30) = ?

18. answer csc 2 (30) = 4

19. Describe the co function theorem and give an example.

20. Answer: Answers will vary. Anything to the likes of “If two angles are cofunctions, then the trig function of one angle will equal the cofunction of its complement. Ex: sin30 = cos60” would do.

21. Ok, now you can use a calculator.

22. Cot(64.8) = ?

23. answer Cot(64.8) =.4706

24. Find the cofunction for the following. Keep your answer in degrees and minutes. Csc(63 o 14’) = ?

25. answer Find the cofunction for the following. Keep your answer in degrees and minutes. Csc(63 o 14’) = sec(26 o 46’)

26. 81 o 9’ – 43 o 47’ = ?

27. answer 81 o 9’ – 43 o 47’ = 37 o 22’

28. Find x Csc(x) = 1. 6734

29. answer X = 36.7 o

30. The rest of the test are right triangle problems.
