This vintage book contains a comprehensive guide to trigonometry.
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is
a branch of mathematics that studies relationships involving lengths and
angles of triangles. The field emerged in the Hellenistic world during
the third century BCE, from applications of geometry to astronomical
studies. This timeless guide is designed with the trigonometry novice in
mind, and contains a wealth of useful exercises and step-by-step
explanations. It is ideal for those looking to gain a good understanding
of trigonometry, and will also be of interest to collectors of
antiquarian literature of this ilk. Many vintage texts such as this are
increasingly scarce and expensive, and it is with this in mind that we
are republishing this volume now, in an affordable, high-quality, modern
edition. It comes complete with a specially commissioned biography of
the author.
