In an extraordinary achievement that has stunned the global mathematics community, two high school students from Louisiana have developed a novel way to prove the Pythagorean theorem—and their ...

Trigonometric ratios are used to find the unknown side or angle of a right-angled triangle. There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each ...

However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine and Cosine rules can be applied to find any unknown side or angle ...
