2. Introduction
• SOH or Sine =
opposite / hypotenuse
• CAH or Cosine =
adjacent/hypotenuse
• TOA or Tangent =
opposite/adjacent

3. Sin
sinA=a/c
sin30=a/15
15sin30=a
7.5=a

4. Cos
cosA = b/c
cos30 = b/15
15cos30=b
13.9 = b

5. Tan
tanA = a/b
tanA = 2.73/3.41
tanA-.8006
A = tan-1(.8006)
A = 38.7

6. Summary
• SOH, CAH, TOA is the three primary
trigonometry functions.
