Advanced Trigonometry (Dover Books on Mathema 1.4tics)

Originally published in 1930, this undergraduate text focuses on methods rather than actual results. For example, it emphasizes remainders and limits in its examination of the procedure for expanding functions in series, and it stresses the establishment of possible forms in its discussion of methods for factoring functions. Contents include properties of the triangle and quadrangle; equations, sub-multiples, and inverse functions; hyperbolic, logarithmic, and exponential functions; and expansions in power-series.
