2. Unit 1 Unit Circle and Trig Functions http://www.youtube.com/watch?v=JspQF0JeTAY Visit the link above for a great review of how to find trig values using the unit circle! However, in order to do this, you must remember how to find sin, cos, and tan using the sides of a triangle. The values are: sin = opp/hyp cos = adj/hyp tan = opp/adj Also use the mnemonic SOH CAH TOA to help keep these straight!
3. Unit 2 Graphs of Trig Functions http://www.youtube.com/watch?v=gj1yf01IatQ Good review of trig transformations on a cos graph
4. Unit 3 Simplify Equations by Using Trig Identities! . http://www.youtube.com/watch?v=9uoKutwuCio Follow the link above to watch a review of how to use Trig identities in solving equations!
5. Unit 4 Solving Trig Equations Use your trig identities and the unit circle to solve equations!
6. Unit 5 Applications of Trig with right and oblique triangles http://www.youtube.com/watch?v=-6GthfFMMWE - review of angles of depression and elevation Use Heron’s Formula to find the area of a SSS triangle: S=1/2 (a + b + c) A= sqrt[s(s-a)(s-b)(s-c)] Use the Law of Cosines and the Law of Sines to solve all other oblique triangles. Finally, be sure to check all answers with your calculator!
