IN this volume the authors “have tried to recapture the spirit of some of the writers of a few generations ago who looked on Trigonometry as a branch of applied rather than of pure mathematics”.

It covers elementary trigonometry to the logarithmic solution of triangles, and makes a good beginning by defining the functions of angles of any magnitude with the aid of co-ordinates.

The original video can be viewed here. For many high school students returning to class this month, it may seem like geometry and trigonometry were created by the Greeks as a form of torture.

Finding a Rare Use for Trigonometry After High School Though it may not seem to apply much to adult life, trig can be an important bridge between different kinds of measurement—and different ...

Most trigonometry students look at triangles on a flat surface. However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used ...

Discovered in the 5 th century B.C. by none other than Pythagoras himself, the Pythagorean Theorem (a 2 + b 2 = c 2) lies at the very foundations of trigonometry.That’s why it was particularly ...

That bonus question asked students to create a new proof for the Pythagorean Theorem, a fundamental principle of geometry, using trigonometry. The teachers weren't necessarily expecting anyone to ...
