trigonometric
Concerning triangle ratios
Trigonometric describes anything relating to trigonometry—the branch of mathematics dealing with relationships between angles and sides of triangles.
Trigonometric functions like sine, cosine, and tangent are fundamental to physics, engineering, and navigation.
A trigonometric identity is an equation true for all values of its variables: We had to memorize trigonometric identities for the exam.
