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 Hypotenuse Opposite x Adjacent
4. LETS PUT THIS TO WORK! 14 5 x 10 Sine (x)= Opposite/Hypotenuse or 5/14 Cosine (x)= Adjacent/Hypotenuse or 10/14 Tangent (x)= Opposite/Adjacent or 5/10
