Trigonometry For Dummies / by Mary Jane Sterling.

Summary:

A plain-English guide to the basics of trig Trigonometry deals with the relationship between the sides and angles of triangles ... mostly right triangles. In practical use, trigonometry is a friend to astronomers who use triangulation to measure the distance between stars. Trig also has applications in fields as broad as financial analysis, music theory, biology, medical imaging, cryptology, game development, and seismology. From sines and cosines to logarithms, conic sections, and polynomials, this friendly guide takes the torture out of trigonometry, explaining basic concepts i.
