Review of
A Brief Trigonometry,
by Robert R. Christian
Five out of five stars
Excellent synopsis of the field
Trigonometry is
one of the areas of mathematics that is fairly easy to understand. In the many years
that I taught college mathematics, there were many students that struggled with
the algebraic components but sailed through the trigonometry. The primary
reason that was cited was that it could be reduced to the visual, and “I am a
visual learner” was the common refrain.
This book is an
excellent synopsis of the field, there is no wasted text. Published in 1965,
there is also no technological component, all functional values used are
presented in tables. This eliminates the occasional student that has a
sophisticated calculator but does not know how to use it. Therefore, over fifty
years after it was published, it is a book that can still be used to effectively
teach the basics of trigonometry.
