- 1. Sine, Cosine,
& Tangent
By Katie Kaelin - 2. Why you use Sine, Cosine, and Tangent
Sine, Cosine, and Tangent are functions of angles.
These angles are represented as waves on a graph.
Often times these angles are found using geometry (finding the angle of x)
Knowing how to find sine, cosine, and tangent using geometry is necessary throughout mathematics. - 3. SIMPLE TRICKS
A simple trick of how to use sine, cosine, and tangent is by using SOH-CAH-TOA
The trick for sin is SOH Sine=Opposite/Hypotenuse
The trick for cosine is CAH Cosine=Adjacent/Hypotenuse
The trick for tangent is TOA Tangent=Opposite/Adjacent
