The word "trigonometric" refers to anything related to trigonometry, which is a branch of mathematics that deals with the relationships between the angles and sides of triangles. Trigonometric functions, such as sine, cosine, and tangent, are mathematical functions that relate the angles of a right triangle to the ratios of its sides. These functions are used in various fields such as physics, engineering, and navigation to solve problems involving angles and distances. Trigonometric identities and equations are also important tools in solving trigonometric problems and proving mathematical concepts. Overall, trigonometric concepts and functions are fundamental in understanding and solving problems involving angles and triangles.
