三角学这一数学分支,各个概念之间充满了对立统一的辩证关系。本文仅从几个方一、锐角三角函数和任意角三角函数之间的对立统一关系锐角三角函数是在直角三角形中研究的,是用直角三角形中边与边之间的比来定义的。它研究的对象是边和角的关系,其中角度和0°到90°之间,即这一特定区域里函
This branch of mathematics in trigonometry is full of the dialectical relationship between opposites. In this paper, we only consider the relationship between the opposites of the triangle, the acute angle trigonometric function and the arbitrary angle trigonometric function. The acute angle trigonometric function is studied in the right angle triangle and is defined by the ratio between the sides and the sides of the right triangle. Its object of study is the relationship between edges and angles, where the angle is between 0° and 90°, that is, the letter in this specific area.
