PURE MATHEMATICS SENIOR FIVE

In pure Mathematics Trigonometry, as the name might suggest, is all about triangles.

More specifically, trigonometry is about right-angled triangles, where one of the internal angles is 90°. Trigonometry is a system that helps us to work out missing sides or angles in a triangle.

In other words, Trigonometry is the branch of mathematics that deals with the properties of triangles and of the trigonometric functions. They were originally developed to describe certain properties of triangles but have applications in math and the sciences far beyond flat geometry. Trigonometry is found all throughout geometry, as every straight-sided shape may be broken into as a collection of triangles. Further still, trigonometry in Pure Mathematics  has astoundingly intricate relationships to other branches of mathematics, in particular complex numbers, infinite series, logarithms and calculus.
