How to learn mathematics;
Analysis method:
The symmetry of "comprehensive method" decomposes complex economic phenomena into many simple components and studies them separately. Its essence is to find out the internal contradictions of things through investigation and study, and to conduct in-depth research on all aspects of contradictions.
Comprehensive method: it is the symmetry of "analysis method". The way to understand and grasp economic phenomena as a whole is to link all parts, aspects and factors of economic phenomena.
Reduction to absurdity:
Also known as "disproof", it is one of the methods of indirect argument, and it is an argument method to establish the authenticity of the topic by judging the falsity of the judgment that contradicts the topic (that is, the antithesis).
Induction:
From a certain point of view about individual things to a larger point of view, the general principle and the explanation method of the principle are deduced from special concrete examples.
Exhaustive method:
Determine the approximate range of answers according to some conditions of the topic, and verify all possible situations one by one within this range until all situations are verified.
Exclusion method:
It refers to the method of transforming several elements in many relationships a limited number of times to eliminate some of them, thus solving the problem.
Alternative method:
An unknown number is represented by one equation and another unknown number in a binary linear equation group, and then it is substituted into another equation to realize elimination, and the solution of this binary linear equation group is obtained.
Image method:
Using images, a special and vivid mathematical language tool, to express the process and laws of various phenomena is called image method.
Scaling method:
Means that inequality a
Matching method:
It refers to transforming a formula (including rational formula and transcendental formula) or a part of a formula into a completely flat way or the sum of several completely flat ways through continuous deformation. This method is often used in identity deformation, and it is one of the powerful means to solve the problem by discovering the hidden conditions in the topic.
