Compared with the problems in 2020, the national three-volume mathematics in 20021is much more difficult, because in the national three-volume mathematics, everyone thinks that many problems are very rare. There are many parabolas, ellipses and hyperbolas in this set of papers. As we all know, the ellipse is almost a plate that will be abandoned when studying, and in these years, few exercises will take the ellipse. Besides, the knowledge contained in ellipsis is very difficult. Therefore, if you want to learn ellipsis well, you still need to work hard. So when considering these special curves, most people will let go of ellipses.

Special curve But in this year's national three-volume math problems, there was such a special curve, so everyone felt clueless during the exam. However, for some candidates, this kind of exercise is relatively simple, because if the conversion can be carried out through the known conditions of some curves, then the students' computing ability and problem-solving ability will be tested. If students have a strong ability to solve equations, then most students can solve these questions.

In fact, the reform content of college entrance examination has been implemented in the full volume of college entrance examination mathematics in 20021,and the core literacy is emphasized in the examination process, and the guidance of mathematics to talent selection is also reflected as much as possible. In this exam, most of the topics highlight the essence of mathematics, and always attach importance to rational thinking, so mathematics is implementing the development policy of education.

Although this year's three-volume mathematics seems particularly difficult, it will be much easier to solve problems if we can grasp the Soviet Union, and the three-volume mathematics is actually more in line with the requirements of today's society, so it can better reflect the application value of mathematics. Although many college entrance examination candidates complain that the national three-volume mathematics is too difficult, this kind of mathematics paper is a greater test for students. If it can be completed, it will also be of great help to the future development.
