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.
Law of Sines & Cosines Word Problems. Name _____________________________________________ sin. = sin = 2 = 2 + 2 − 2 ∙ cos. Also recall the formula formula for area of a triangle: = ∙ sin. For each item, draw a diagram, write and equation, and solve.
Law of Sines and Cosines Worksheet (This sheet is a summative worksheet that focuses on deciding when to use the law of sines or cosines as well as on using both formulas to solve for a single triangle's side or angle)
1 Sine and Cosine Rules. In the triangle ABC, the side opposite angle A has length a, the side opposite angle B has length b and the side opposite angle C has length c. The sine rule states. A. sin A sin B sin C. = = b c. C. a.
The LAW OF SINES is a powerful triangle tool which is used to find missing sides or angles of ANY triangle. By matching up angles with their opposite sides , the equation is:
