8.4- Sine, Cosine, and Tangent
SohCahToa
Sine Cosine Tangent
Opposite Leg Adjacent Leg Opposite Leg
Hypotenuse Hypotenuse Adjacent Leg
Sin(A)=a/c Sin(B)=b/c
Cos(A)=b/c Cos(B)=a/c
Tan(A)=a/b Tan(B)=b/a
Properties
Sin(A)=Cos(B)
Cos(A)=Sin(A)
Tan(A) is reciprocal Tan(B)
8.5- Angles of Elevation and Depression
Properties
-Angle of Elevation = Angle of Depression
-Diagonal acts as a transversal, cutting through the top and bottom of the Z chart
-Angles of elevation and depression are formed by this transversal
-Top and bottom of the Z chart are parallel lines
