The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

The mathematical study of triangles has just got a whole lot simpler, according to a researcher who says his new theory of trigonometry is easier to use and more accurate. Associate Professor Norman ...

Trigonometry allows one to systematically convert between measurements of angles and measurements of length, a topic that has interested mathematical astronomers from antiquity. Ancient Greeks also ...
