1. Title: Trigonometric Functions LEQ: What are the trigonometric functions and how are they used to solve right triangles?

2. The Trigonometric Functions SINE COSINE TANGENT

3. Trigonometry: SINCOSTAN or SOHCAHTOA These functions are ONLY used with RIGHT Triangles!!!

4. First identify the sides of the triangle The longest side is called the… Hypotenuse. The side opposite to the angle is called the… Opposite. The remaining side is the… Adjacent OPP ADJ HYP x SOHCAHTOA

5. SINE Prounounced “sign”

6. Prounounced “co-sign” COSINE

7. Prounounced “tan-gent” TANGENT

8. Prounounced “theta” Greek Letter  Represents an unknown angle

9. opposite hypotenuse adjacent hypotenuse opposite adjacent

10. 6 8 10 SOHCAHTOA

11. Find the sine, the cosine, and the tangent of angle A. Give a fraction and decimal answer (round to 4 places). 9 6 10.8 A

12. We need a way to remember all of these ratios…
