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 ...

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 ...

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 ...

Birds can do trigonometry. That's just one of many theorems in "The Math Instinct: Why You're a Mathematical Genius (Along With Lobsters, Birds, Cats and Dogs)" by Keith Devlin, 58. That unwieldy ...

I remember very little about high school trigonometry, other than the teacher was tough enough she could have played Dorothy’s bicycle-riding, wicked-witch Trig was a “solid” in those days; courses ...
