tan:正切 cos:余弦 应用场景:这三个词是三角函数的基本组成部分,在数学、物理、工程学等多个领域中都有广泛应用。它们用于描述直角三角形中边长的关系,以及在周期性现象(如波动、振动)中的分析。 造句例句: 中文:在直角三角形中,正弦、余弦和正切是三种基本的三角函数。 英文:In a rig...
(In a right triangle, cos A is equal to the length of the adjacent side divided by the hypotenuse.) 3. tan(正切) - 英文表达:tangent - 发音:英['tændʒənt],美['tændʒənt] - 释义:正切是直角三角形中对边与邻边的比例,即tan A 等于对边长度除以邻边长度。 - 例句:在直角...
