数学公式对于数学来讲,就好比是子弹对于枪支,它在数学中的重要性不言而喻.例如,在三角函数中,三角公式在物理学、天文学、测量学以及其他各种应用技术学科中都有着极其广泛的应用.但是,学生在刚开始接触学习三角公式时,总是感到非常困难,有点力不从心的感觉.三角公式难以记忆的原因,主要有以下两个方面:一方面是公式繁多.笔者做了粗略的统计,常用的公式(包括三角函数定义,同角三角函数的基本关系式,诱导公式,两角和
Mathematical formulas for mathematics are like bullets versus guns, and its importance in mathematics is self-evident. For example, in trigonometric functions, trigonometric formulas are used in physics, astronomy, surveying, and various other applied technology disciplines Has a very wide range of applications.However, students at the beginning of contact learning triangle formula, always feel very difficult, a bit powerless feeling.The reasons for the triangular formula difficult to remember, mainly in the following two aspects: On the one hand is the formula The author made a rough statistics, commonly used formulas (including the definition of trigonometric functions, the basic relations with the trigonometric functions, the induction formula, the two angles and
