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 ...

THE Paralogistes pseudomathematicus has become so rare, or possibly so shy, that it is a real pleasure to find that the species is not extinct. Alack! that De Morgan is not with us, to do justice to ...
