Anonymous users2024-02-12The topics that high school students can do well in mathematical modeling include optimization problems, ** problems, and evaluation problems.
Mathematical modeling is to establish a mathematical model according to the actual problem, solve the mathematical model, and then solve the practical problem according to the results.
When it is necessary to analyze and study a practical problem from a quantitative point of view, people should use mathematical symbols and language to establish a mathematical model on the basis of in-depth investigation and research, understanding the object information, making simplified hypotheses, and analyzing the internal laws.
Mathematical model concepts
1. Mathematical model (mathematical model) is a kind of simulation, which is an abstract and concise description of the essential attributes of the actual subject with mathematical symbols, mathematical formulas, programs, graphics, etc., which can explain some objective phenomena, or can lead to the future development law, or can provide the optimal strategy or better strategy in a certain sense for controlling the development of a certain phenomenon.
2. Mathematical models are generally not a direct copy of real problems, and their establishment often requires people to observe and analyze real problems in depth and subtlely, and also requires people to flexibly and skillfully use various mathematical knowledge.

This book is not expensive, a waste of money, you can't be superstitious about it or something, a top student said, you only need to do a book thoroughly, and then follow up with some questions assigned by the teacher.

Anonymous users2024-02-09There are thousands of ways to solve problems in high schools, but the most commonly used are the following.
Isolation method, integral method, equivalence method, symmetry method, assumption method, inverse method, conservation method, special case method, substitution method, estimation method, proportion method, algebraic method, trigonometry method, geometric method, microelement method. Hope to adopt.

You haven't learned at all? Is this true for every one? Do you have a good foundation in junior high school? >>>More
When we use the commutation method, we should follow the principle of being conducive to operation and standardization, and we should pay attention to the selection of the range of new variables after the commutation, and we must make the range of new variables correspond to the value range of the original variables, and cannot be narrowed or expanded. As in the above examples, t>0 and [0,. >>>More
I've heard a champion of a simple learning network learn mathematics like this, he said that you must not ask the sea of questions, nor can you blindly learn high school mathematics is like the sea, there are too many knowledge points, each knowledge point can be extended, endless, if you have to understand all of them, it is unrealistic >>>More
1. Recall the basic knowledge of mathematics in the past 3 years in high school, not only rote memorization, but also understanding, understanding is to do problems, you can do some typical exercises, not only do difficult problems, but also do some basic problems. >>>More
To follow the teacher's way of thinking, do not understand must ask, homework and exercises must be completed independently even if the completion is very slow, selectively look at the answers, especially some off-topic strange questions must not remember the answers, each question must understand its connotation, that is to say, the problem solving ideas and methods of this question are the key, do not record the main topic when taking notes, that is, the teacher's class examples, easy to use when reviewing, and to establish a wrong question book, do not write the process, only remember the answers, as soon as you have time, look through to find ideas, Before the exam, don't just look at the knowledge points and wrong questions, but also do one or two questions to practice your hands.
