极限是微积分的基本工具,在现代数学中有广泛的运用.但在高中仅涉及其描述性定义,那么,极限思想与中学所学的其他数学知识又有什么关联呢?一般而言,我们在解中学数学题目时都是有较为明确的思路的,解方程有解方程的方法,求矩阵的特征值和特征向量也有一定的步骤,所以通常情况下数学解题是有规律可循的.但是一张卷子上总会有几道解题思路不明确的数学问题,这样的题目往往有较大的区分度,且往往无规律 Limit is the basic tool of calculus, and it is widely used in modern mathematics, but in high school only involves its descriptive definition, then what is the relationship between limit idea and other maths learned in high school? Generally speaking, we Solving the problem of middle school mathematics are more clear ideas, solving equation method of solving equations, the matrix eigenvalues ​​and eigenvectors also have certain steps, so under normal circumstances the mathematical problem-solving is a rule-based. However, there will always be a few pieces of paper to solve the problem of thinking is not clear mathematical problems, such topics tend to have a greater degree of distinction, and often irregular
