#trigonometry

Trigonometry is the study of the relationships between the sides and angles of triangles. It's used to model and solve problems involving waves, orbits, and other cyclical phenomena. The documents here include a course outline that lists topics in algebra and trigonometry, such as trigonometric expansions and matrices. There are also exam questions that cover trigonometry alongside other precalculus topics. One document shows some maths equations and a contents page.
