trigonometric
意味: Relating to trigonometry, the branch of mathematics that studies the relationships between the sides and angles of triangles, especially through functions such as sine, cosine, and tangent.
Trigonometric functions are essential across science and engineering, from modelling wave patterns and oscillations to calculating distances in navigation and surveying. The six standard trigonometric functions are sine, cosine, tangent, cotangent, secant, and cosecant. The adjective is almost exclusively used in technical and academic contexts. It collocates with 'function,' 'identity,' 'equation,' 'ratio,' and 'table.'
