Who told me the limit (high number)

The limit and continuity of advanced mathematics are the contents of the previous chapters, which is an important part of the introductory part for students who have just entered colleges and universities. It is the primary stage from "elementary mathematics" to "advanced mathematics". First, the concept of limit conceptually, we must first master the idea of approximation. The so-called limit means that when the variables of a function have a certain trend (this trend is unique), then the dependent variables of the function also have a trend, which is corresponding to the changes of the independent variables. Generally speaking, the function value is infinitely close to a certain value because of the change of the function variable. We call this definite value the limit of the function when the variable produces this change! Mathematically speaking, approximation refers to the change of function, which is expressed as. I won't repeat this question. You can refer to the introduction in the textbook. In my class, in order to let students refer to my conclusion, I praised such a Haikou. I said that as long as you remember these contents carefully, the limit content required by the high number part can basically be solved. Now that I think about it, this is not a harbor. No matter how difficult mathematics is, it is also the basic content. The key to the basic method is skill. I remember I did a limit problem in my blog. At that time, some netizens exclaimed that it was too flattering! In fact, it is not flattering, but there are rules to follow! I hope what I wrote today can help you with your study! When we see a math problem, the first thing to do is to examine the problem and do the limit problem. The first is to look at its basic form, what form it belongs to and what method it uses. This can basically be applied directly. 1, the limit of continuous function. I won't elaborate on this. In two sentences, first look at whether it is a continuous function and directly bring in the independent variable. /clam catfish/blog/item/EAA7563E3410cdcb7d1e71da.html.
