Algebra 2 + Trigonometry

Unit 9 – Trigonometric Applications

This unit finishes our coverage of trignometry in this e-text.  This unit develops the three main formulas, the area, the Law of Sines, and the Law of Cosines, in relationship to classic right triangle trigonometry.  The ambiguity of Sines is explored.  Application problems in the last lesson show the utility of each of these formulas.
