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.

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”.

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.

I didn’t have a protractor handy, unlike when I was in high school and carried one at all times. But then I realized it was a rare chance to apply some trigonometry.

Trigonometry Formulas: There are very few topics in mathematics that trouble students more than trigonometry and calculus. In fact, it is the base of many advanced math concepts and is also ...

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 ...

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 ...
