根限是高中数学的重要概念之一,是进一步学习高等数学的工具.平时学习中多重视求极限和证明极限问题,对于作为一种重要的思想方法则缺少关注,特别在立体几何的学习中,通过观察动态过程中所处位置的极端状态(极限情况),即当一个变量无限地接近一个定量时,此时的变量可看作此定量,本文中的几何体求值问题尤其是这样,可以避开逻辑推理和复杂运算,得到简洁理想的解题效果.
Rooting is one of the important concepts of high school mathematics. It is a tool for further study of higher mathematics. In peacetime learning, more emphasis is placed on finding the limits and proving the limits. For lacking attention as an important method of thought, especially in the study of solid geometry By observing the extreme state (limit condition) of the position in the dynamic process, that is, when a variable is infinitely close to a quantification, the variable at this time can be regarded as this quantification. In particular, the geometry evaluation problem in this paper can be Avoid logical reasoning and complex operations to get a simple and ideal solution.
