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 ...

A 3,700-year-old Babylonian clay tablet reveals the oldest known trigonometric table, showing ancient scribes used precise triangle ratios.

The class Trigonometry: Sine, Cosine, and Tangent discusses the three basic ratios that are the basis for trigonometry. Trigonometry is based on the specific relationships between the sides and angles ...

Some exact trigonometric values are equivalent. For example, \( \frac{1}{√2}\) = \( \frac{√2}{2}\). The denominator has been rationalised. To be successful with exact trigonometric values, especially ...
