## Take the SHORT CUT: Think: Quadrant? Reference Angle?

 Write each expression in terms of the same function of a first quadrant angle.    Connect the answer dots in order. 1. sin (350°) = -sin(10°) 2. sin (225°) = -sin(45°) 3. sec (-20°) = sec(20°) 4. tan (110°) = -tan(70°) 5. cot (150°) = -cot(30°) 6. csc (190°) = -csc(10°) 7. tan (-75°) = -tan(75°) 8. sec (250°) = -sec(70°) 9. tan (-5°10') = -tan5°10') 10.tan (370°) = tan(10°) 11. sin (400°) = -sin(40°) 12. csc (-55°) = -csc(55°) 13. sin (-400°) = -sin(40°) 14. cos (294°50') = cos(65°10') 15. cot (172°) = -cot(8°) 16. sin (-560°) = sin(20°) 17. tan (165°) = -tan(15°) 18. csc(300°) = -csc(60°) 19. sin (745°) = sin(25°) Start a new line. 20. cos (100°) = -cos(80°) 21. cot (-152°) = cot(28°) 22. csc (-300°) = csc(60°) 23. cot (-130°) = cot(50°) 24. sec (-62°) = sec(62°) 25. cos (-100°) = -cos(80°) Start a new line. 26. tan (-83°) = -tan(83°) 27. csc (216°) = -csc(36°) 28. csc (160°36') = csc(19°24') 29. tan (-185°) = -tan(5°) 30. cos (102°) = -cos(78°) 31. tan (97°) = -tan(83°) Start a new line. 32. sin (-320°) = sin(40°) 33. cot (-220°) = -cot(40°) 34. sin (315°) = -sin(45°) Circle this answer. 35. cos (-10°) = cos (10°)
