First, elementary mathematics must be able to take the postgraduate entrance examination. Mathematics tests advanced mathematics, that is, calculus, linear algebra and probability theory, all of which belong to advanced mathematics. Advanced mathematics will not explain the knowledge points of elementary mathematics, but will be used directly.
Without the foundation of elementary mathematics, it is difficult to learn advanced mathematics well, such as finding area, derivative, factorization and formula, which need to be studied.
Second, being familiar with formula theorems does not require us to understand every formula theorem, but it requires us to be able to use it. Because the high number of the postgraduate entrance examination will not be so profound, it is nothing more than going around, and we need to remember the formula theorem.
If you can't remember it, you won't be able to do the problem at all. For example, a series of formulas for solving the original function, the formula for solving the integral of the surface integral curve, and Lagrange's mean value theorem must be memorized.
Third, we must brush enough basic questions. Since it is a basic skill, don't mention those particularly difficult questions. You must brush enough basic questions. Just because I didn't brush too many questions, I didn't do well in the math exam.
A basic problem is one with a solid foundation. This kind of topic must be done quickly and accurately. I think the basic questions of postgraduate entrance examination should stand at least 75%. As long as the basic questions are well brushed, the problems will become simple.
It is important to study math hard, but sometimes it depends on the method. If we grasp the method correctly, as long as we work hard enough, we will certainly get good grades in the exam. I think I know the method, but I don't work hard enough. I hope everyone has enough perseverance and perseverance!
