RATIONAL TRIGONOMETRY:COMPUTATIONAL VIEWPOINT

摘要

Main idea behind rational trigonometry. Traditional trigonome-try uses non-algebraic functions such as sin(x) or cos(x) to "solve"triangles, i.e., to use the values of some of its parameters (sides al,a2, a3, angles A1, A2, A3) for finding the values of others parame-ters. The use of non-algebraic functions complicates mathematicalanalysis, makes computations more difficult, and makes trigonome-try more difficult to learn.
