Can the math problem in the college entrance examination only be the first?
No, you can choose to do the math problems in the college entrance examination, and those two questions are selected as the corresponding math elective courses 4-4 and 4-5. At present, most schools only choose to teach one elective 4-4, which means they can only do one topic.

Since you have chosen a topic, you should choose one. Take the mathematics of Jiangsu college entrance examination as an example, science candidates have additional questions in mathematics, the first four questions are multiple-choice questions, and the last two questions are required questions. If you choose to do all the questions, the college entrance examination papers will only be graded according to the first two questions, and the last two questions will not be changed. Therefore, the consequence is that the college entrance examination time is wasted, and the following questions can't be finished.

The college entrance examination paper will also be mentioned in the title. If you choose to do all the questions, you will only score according to the first few questions. If you do it all, you are good yourself, because your teacher didn't teach you some knowledge you need to choose a topic. Because teachers must choose elective courses that can be easily graded, each school has its own emphasis on topic selection and can only say hello.

Extended data:

1, topic selection

The so-called topic selection is to choose one of the three questions that you are best at. Some schools may have learned all three questions, so you should choose according to your own specialties and the difficulty of the questions; And some schools may have only studied one of them, so you can only choose the one you have studied, because you are most familiar with it and only know it.

Step 2 check the problem

This is the basic step of doing the problem. You can draw the key data. If you choose the course of geometric proof, you'd better mark the angular relationship on the diagram.

Step 3 ask a question

4- 1 Selected Lecture on Geometric Proof: Pay attention to the steps, the application of the theorem must be accurate, and the application of the theorem must require no less conditions.

4-4 Coordinate System and Parameter Equation: Generally, the first question is very simple. As long as you remember the transformation relationship between variables in the polar coordinate equation, the parametric equations of several special equations can be scored.

The second problem can be solved by parametric equation (provided that you can use it very skillfully), which can save a lot of operations; You can also use the knowledge of conic curve to solve it, but it will be very troublesome.

Lectures on 4-5 Inequalities: Inequalities should be relatively simple. The content of the common test is absolute inequality and Cauchy inequality, but it can be done with other knowledge. Be careful when you do inequalities. If the piecewise function is discontinuous after the absolute inequality is removed, you are likely to make a mistake.
