Degrees - Radians - Sine - Cosine - Tangent
SOH CAH TOA
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Two Special Right Triangles
45-45-90
30-60-90
The 45-45-90 Triangle
1 - 1 - sqrt(2) triangle for the lengths of the sides
sin(45) = sqrt(2) / 2 = cos(45) [both the same]
tan(45) = 1
If theta < 45, then tan(theta) < 1
If theta > 45, then tan(theta) > 1
