What about the choice of mathematics in the college entrance examination? This is the last question in the math test paper. Mathematics has two optional textbooks, and the last question will be given from each of the two textbooks. You don't need to write both topics. You just need to pick a topic that you are good at or are sure to get more points.

It is best to study both elective textbooks, so that you can choose a relatively simple one to take the exam.

Multiple-choice questions, like other questions, have criteria for scoring. Since you choose to do the problem, you must choose to do it. Don't waste the time of the college entrance examination. If you can't finish the problem in the future, that's too bad. 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. Each school has different emphasis on topic selection and problem solving. Teachers generally choose elective courses that are easy to grade. If they are all multiple-choice questions and questions, it can only show that the candidates are excellent and will not increase the test scores.

The coordinate system and parameter equation of the 22nd question (elective course 4-4) of the college entrance examination mathematics test 10 score, and the inequality of the 23rd question (elective course 4-5) 10 score, so choose one.

The main test points of coordinate system and parametric equation are the mutual transformation of parametric equation, polar coordinate equation and constant equation, linear parametric equation and its application, circular and elliptic parametric equation, polar coordinate equation and its application.

The main test points of inequality selection are absolute inequality, Cauchy inequality, inequality proof, constant establishment (tradable) and so on.
