1, Introduction to Examination Time and Test Paper Scores of Mathematics Competition
In 2023, the national high school mathematics competition league is mainly written, and candidates need to take one test and two tests. The test time of the first test is 80 minutes, the time of the second test is 170 minutes, and the test ends at 12: 30 in the morning. Try to fill in the blanks with 8 questions; 8 points for each question. Answer 3 questions, 16, 20, 20. ? Try two and answer four questions: 40 points for the first two questions; The last two questions are 50 points each.
Step 2 score
For most students, the league is the most important game. The league will select the well-known provincial first, second and third prizes. Among them, the provinces are responsible for judging the first prize, and then send the examination papers of the first prize to the organizer, who will re-evaluate them, and finally the competent unit (China Association for Science and Technology) will be responsible for the final evaluation and announcement. The second prize and the third prize are decided by the provinces.
The ranking of the results of the semi-finals determines the provincial awards, that is, the provincial awards, that is, the first, second and third prizes of the national high school mathematics competition (provincial division), referred to as "province one", "province two" and "province three". According to the ranking, each provincial division will select the students who won the first prize and form a provincial team to participate in the China Mathematical Olympics (CMO).
Examination scope:
1, give it a try
The outline of the preliminary test competition of the national senior high school mathematics league matches the teaching requirements and contents stipulated in the full-time middle school mathematics syllabus, that is, the knowledge scope and methods stipulated in the college entrance examination are slightly improved, and the preliminary test of probability and calculus is not taken.
Step 2 try again
(1) plane geometry
Basic requirements: master all the contents of junior high school mathematics syllabus. Supplementary requirements: area method. Several important theorems: Menelius Theorem, Seva Theorem, Ptolemy Theorem and siemsen Theorem.
Several important extreme values: the point with the smallest sum of the distances to the three vertices of a triangle-fermat point. The center of gravity is the point where the sum of squares of the distances to the three vertices of a triangle is the smallest. The center of gravity of the point with the largest distance product from a triangle to three sides.
(2) Algebra
On the basis of the first test outline, other contents are needed: periodic functions and images of periodic functions with absolute values. Triple angle formula, some simple identities of triangle, triangle inequality. The second mathematical induction method: recursion, first-order and second-order recursion, and characteristic equation method. Function iteration, finding n iterations, simple function equation.
The above data comes from the National Education Examination Network.
