A great deal of the material on the law
of sines (including the proofs and problems) was taken from *Geometry
Revisited *by H.S.M Coxeter and S.L. Greitzer (1967, The Mathematical
Association of America, Inc., Washington , D.C., pp. 1-3). Special
thanks to Dr. Jimmy Woods of North Georgia College & State
University for introducing me to this excellent book.

The sample problems in the introductory
material on the law of sines and the summary of the ambiguous
case was taken from the textbook *Algebra and Trigonometry (3rd
edition) *by Roland E. Larson and Robert P. Hostetler (1993,
D.C. Heath and Company, Lexington, MA, pp. 551-554).
