Find the other five function values. 17. sin ,11 19, tan = 5,111 18. see#2 ,1 20. cot =-4.1V 21. Find the six trigonometric function values for the following 17 Solve, finding all solutions: 22. tan z=v/3 23. 2cos2 ! 24. 2 sin2-5 sinz +2

Solution

1. 50 X  /180 = 5/18 radians

2. 120 X /180 = 2 / 3 radians

3. 375 X / 180 = 25 / 12 radians

4. -12 X / 180 = - / 15 radians

5.(-5 /6) X (180 / )= -150 degree

6. ( 35/12) X (180 /)= 525 degree

7. (7/8)X (180 /) = 157.5 degree

8. (-2/3) X (180/) = -120 degree

9.sin 5/3 = -sqrt (3)/2

10. tan /6= 1/ sqrt (3)

11. csc 11/4 = sqrt (2)

12.cos (-2/3) = - 1/2

13. sec 11 /6 = 2/ sqrt (3)

14. sin (-3/2) = 1

15. cot 5/4 = 1

16. cos 5/6 = - sqrt (3) /2
