DESCRIPTION:

Innovative, clear, well written trigonomety textbook I enjoyed this textbook, especially the way some subjects were so well explained. Not only does this text cover a good bit of material, but it also reveals the way in which the author thinks about this subject. I have noticed, both with this text and the previous two which I have commented on, that certain aspects of the subject become much more transparent or understandable when reexamined with a keener mathematical ability than, at least I possessed, when I was first exposed to these subjects in hi. Terrific! Finally - a trig book that doesn't talk down to students. Gelfand treats his readers as intellegent, curious, and competent. This goes far especially with kids.Most other trig books are written by educational consultants who view the subject as a odorous swamp that you have to slog through. They distract the reader with glitzy graphics and useless photos. No such chartjunk here. It's from someone who loves the subject, and places the mathematics first.I feel like an avuncular mathematician is showin. L. D. Rafey said Outstanding Math Text. I rarely compose reviews even if I happen to really appreciate a book. But THIS is one of those rare exceptions!Gelfand (who also happens to rank among the "Outstanding Math Text" according to L. D.

Throughout, the treatment stimulates the reader to think of mathematics as a unified subject." ** L'enseignement Mathématique**"As a teacher I enjoyed this book enormously and I will doubtless borrow many of the plums to spice up my lessons…. For that ideal student who is to be prepared to be challenged to think what the subject is really about, and has the patience to excavate the basic ideas for all they are worth before jumping on to the next chapter, it should prove to be a godsend." **The Mathematical Gazette**"The authors tried to explain the results of trigonometry as simply as possible…. "Covers all of the basic topics that a high school or beginning university student should be expected to

It is a very old subject. So trigonometry is a part of pre-calculus, and is related to other pre-calculus topics, such as exponential and logarithmic functions, and complex numbers.. Trigonometry is an important introduction to calculus, where one stud ies what mathematicians call analytic properties of functions. This way of thinking is useful not just in calculus, but in many mathematical situations. Many of the geometric results that we now state in trigonometric terms were given a purely geometric exposition by Euclid. It also has many applications to physics, astronomy, and other branches of science. It originates i
