Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

Alex Tabarrok points to a new paper this morning that should thrill data nerds and chart enthusiasts everywhere. Steven Piantadosi of the University of Rochester has produced a simple equation with ...

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 ...

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 ...
