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 is a branch of mathematics that studies relationships between the sides and angles of triangles. Trigonometry is found all throughout geometry, as every straight-sided shape may be broken ...

The angles are labelled with capital letters. The opposite sides are labelled with lower case letters. Notice that an angle and its opposite side are the same letter. The sine rule is: \(\frac{a}{\sin ...

It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The shape ABCDEFGH is a cuboid. Length AB is 6 cm, length BG is 3 cm and length FG ...

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 ...
