1. Hurray Trigonometry!! By: Nate Webber January 9, 2011

2. Unit 1 The Unit Circle! Trig functions! There is no better way to understanding the trig values of special angles then by knowing the whole Unit Circle!

4. Domain: all real numbers

5. Range: [-1 , 1]

6. Period = 2pi

7. x intercepts: x = k pi , where k is an integer.

8. y intercepts: y = 0

9. maximum points: (pi/2 + 2 k pi , 1) , where k is an integer.

10. minimum points: (3pi/2 + 2 k pi , -1) , where k is an integer.

11. symmetry: since sin(-x) = - sin (x) then sin (x) is an odd function and its graph is symmetric with respect to the origon (0 , 0).

13. Domain: all real numbers

14. Range: [-1 , 1]

15. Period = 2pi

16. x intercepts: x = pi/2 + k pi , where k is an integer.

17. y intercepts: y = 1

18. maximum points: (2 k pi , 1) , where k is an integer.

19. minimum points: (pi + 2 k pi , -1) , where k is an integer.

20. symmetry: since cos(-x) = cos (x) then cos (x) is an even function and its graph is symmetric with respect to the y axis.

22. Domain: all real numbers except pi/2 + k pi, k is an integer.

23. Range: all real numbers

24. Period = pi

25. x intercepts: x = k pi , where k is an integer.

26. y intercepts: y = 0

27. symmetry: since tan(-x) = - tan(x) then tan (x) is an odd function and its graph is symmetric with respect the origin.

28. intervals of increase/decrease: over one period and from -pi/2 to pi/2, tan (x) is increasing.

30. Unit 4 Solving Trig Equations! Here are a few examples: Everything that was learned in the last 4 Units were put into this chapter to basically sum everything up 

31. Unit 5 Applications of Trig-Right Angles Oblique Angles! This Unit was a relaxing unit. There were only a few formulas to understand and the problems were that bad. The fun part about this unit was being able to put it into real life scenarios! Such as finding how tall a building is Law of Consine! Law of Sine!

32. Unit 5 (continued) So how do you know when to use which?
