Notes - Trigonometry *I can solve right triangles in real world situations using sine, cosine and tangent. *I can solve right triangles in real world situations using inverse sine,cosine and tangent.

2
Understanding Opp, Adj, & Hyp In order to understand how to use the trigonometric functions of sine, cosine, and tangent you must understand opp, adj, and hyp

3
A C B Opposite Side Adjacent Side Hypotenuse (hyp) (opp) (adj)

4
A C B Opposite Side Adjacent Side Hypotenuse (hyp) (opp) (adj)

5
Three basic trig functions: Sine, Cosine and Tangent

6
SOHCAHTOA

7
SOH Sin A = Opposite Hypotenuse

8
A C B This is what a problem using sine would look like. X 12 m 42 You would set the problem up like this: Sin A = Sin 42 = opp hyp x 12

9
SOHCAHTOA CAH Cos A = Hypotenuse Adjacent

10
A C B This is what a problem using cosine would look like. X 9 m 38 You would set the problem up like this: cos A = cos 38 = adj hyp x 9

11
SOHCAHTOA TOA Tan A = Opposite Adjacent

12
A C B This is what a problem using cosine would look like. X 11 m 52 You would set the problem up like this: tan A = tan 52 = opp adj 11 x
