Trigonometry
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles, especially rightangle triangles. A set of functions, called trigonometric functions, represents these relationships in mathematical terms. Listed below are videos of trigonometry lessons to help kids learn about trigonometry and related concepts.
