Study Notes
Trigonometric Ratios
-
Sine (sin θ) = Opposite / Hypotenuse
-
Cosine (cos θ) = Adjacent / Hypotenuse
-
Tangent (tan θ) = Opposite / Adjacent
-
SOH CAH TOA is a helpful mnemonic device to remember these ratios. (Sine = Opposite over Hypotenuse, Cosine = Adjacent over Hypotenuse, Tangent = Opposite over Adjacent)
