  1. Cosine 3rd TypeTrigonometry Project Based Geometry Paul Streff Revised: 1-27-13

  2. 3rd type Trig formula 2nd Cos Side Adjacent/Hypotenuse = Adjacent Angle Hyp. Adj Angle

  3. Example 1 2nd Cos 1.3/3.0 = Adjacent Angle 64.3207 degrees = Adjacent Angle 3.0 1.3 Angle

  4. Example 2 2nd Cos 1.8/6.2 = Adjacent Angle 73.123 degrees = Adjacent Angle 6.2 Angle 1.8

  5. Example 3 2nd Cos 0.9/2.3 = Adjacent Angle 66.964 degrees = Adjacent Angle 2.3 Angle 0.9

  6. So to Find the Angle: • We Just have to Push the 2nd button & divide?? • Bring it ON…

  7. This is uncomfortable..
