1, direct method

When multiple-choice questions are adapted from calculation questions, application questions, proof questions and judgment questions, they can be done directly according to calculation questions, application questions, proof questions and judgment questions. After determining the answer, you can find it in the options.

2. Screening method (exclusion method)

Get rid of the false and keep the true, screen out some conclusions that are easy to judge and irrelevant, narrow the selection range, and then get the correct answer from the remaining conclusions. If there is only one conclusion after screening out the problems, it is the option.

3. Special value method

According to the information provided in the answer, select some special cases for analysis, or calculate some special values, or replace the letter parameters with specific values, or take the proportional number as a specific number to bring people. In short, it is often very simple to change the general form into a special form before judging.

4. Verification method (alternative method)

Substitute each option into the stem one by one and verify it, or choose a special value for proper testing, or take other verification means to judge whether the choice is right or wrong.

5. Mirror image method

We can draw a sketch according to the meaning of the question first, and then draw a conclusion by referring to the practice, shape, position and nature of the characters and integrating the characteristics of the image.

6. Heuristic method

If you want to organize comprehensive and multi-object questions, you can establish geometric models and algebraic structures according to the meaning of the questions, and then try and choose by mistake, paying attention to the flexible use of the above methods.

7. Guess and answer (language sense method)

Multiple choice questions have the possibility of guessing points, which is called opportunity points.

Mathematics required questions in the college entrance examination:

1, functions and derivatives

This paper mainly examines the related concepts such as set operation, function definition domain, range, analytical formula, limit, function continuity, derivative and so on.

2. Plane vector and trigonometric function, trigonometric transformation and its application.

This part is the focus of the college entrance examination, but it is not difficult. It mainly contains some basic or intermediate problems.

3. Sequences and their applications

This part is the focus and difficulty of the college entrance examination, and some comprehensive questions should be done.

4. Inequality.

This paper mainly investigates the solution and proof of inequality, rarely alone, mainly through the size comparison in solving problems. Emphasis and difficulty of college entrance examination.

5. Probability and statistics

This part is related to our life and is an applied problem.

6. Qualitative and quantitative analysis of spatial relationship.

Mainly to prove parallelism or verticality, and to find the angle and distance. It is necessary to investigate the familiarity and application of the theorem.

7. Analytic geometry

This test is difficult, computationally intensive, and usually contains parameters.
