Trigonometry: Law of Sines, Law of Cosines, and Area of Triangles. Formulas, notes, examples, and practice test (with solutions) Topics include finding angles and sides, the “ambiguous case” of law of Sines, vectors, navigation, and more.
Trigonometry Word Problems Example: You fly a kite 4 feet offthe ground with 300 feet of string. There is a 40 mile per hour wind, and the kite forms a 29 angle from the ground. How high is the kite (from the ground)? Basic Steps: 1) Draw a picture 2) Label the parts 3) Isolate the triangle 4) Solve 5) Answer the question
The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)
