Chapter 4 Mathematics Competition Training Class

"Come on, haven't you all entered the National Mathematics League before? The school has opened a league training class specifically for you. If you are willing to try your best, we will give it to you every week in the next few weeks. Take four competition training sessions.”

After the three of them arrived in the office, the head teacher smiled and said to them that the head teacher's name was Wang Anyu and he taught them physics.

"Of course, it's voluntary. You are in your senior year after all. You don't have as much time as your sophomore year, so it's up to you to choose."

Before Lin Xiao could speak, a boy wearing glasses next to him said very confidently: "I'm participating. I've been preparing for the league for a long time. I should be sure to win the provincial first prize this time."

Lin Xiao raised his eyebrows.

This boy's name is Jiang Jie. He is a famous academic figure in his class. He is basically among the top five in the school. He occasionally ranks first in the grade. However, although his academic performance is very good, he has a bit of a nerd. Because he is usually either studying or on the way to study.

In addition, because he usually has a sense of pride when talking, he basically has no close friends.

According to him, Newton is his idol, and Newton is the unruly kind. Even his signature is "Only cattle and sheep flock in groups, and ferocious beasts only walk alone."

Of course, Lin Xiao would not comment on this. After all, there will always be people with strange psychology.

When Jiang Jie said this, Teacher Wang smiled and encouraged: "Okay, teacher believes in you."

Then Teacher Wang looked at Lin Xiao and another boy and asked, "What about you?"

Another boy named Xu Lin shook his head and said: "I will not participate in this cram school. I feel that the tasks in the senior year of high school are still relatively heavy, but I will also participate in the competition by then."

"Well, that's okay. You might be able to win a prize by participating in the competition. Anyway, it's at least useful." Teacher Wang said.

"Lin Xiao, where are you?"

"I...I won't participate either," Lin Xiao said, "But like Xu Lin, I will also go on the day of the competition."

"good."

Teacher Wang nodded with satisfaction. In fact, in his opinion, this was the best result. Lin Xiao and the second boy were ranked in the top 30, so they should focus on the college entrance examination. After all, according to their Based on the school's past results, the probability of winning the provincial second prize in the mathematics league is relatively small. As for the provincial first prize, it is even less likely. It is better to spend more time on the college entrance examination. As for the third prize, for their current Grades are completely useless.

Jiang Jie's grades are very good, so it's just right to take some time to study this stuff now.

Moreover, Jiang Jie just said that he had a chance to win the provincial first prize, maybe it will happen?

In this case, when Jiang Jie participates in Qingbei's independent enrollment, the provincial first prize will give him a lot of extra points. If he participates in an autumn camp or something, it will be more stable.

"That's it, Jiang Jie, you go to the 303 multimedia classroom on the third floor of the laboratory building now, and then you will train with the other students in the second and third grade classes."

"Lin Xiao, Xu Lin, then you should review your own first. If the training class distributes some special papers, I will help you get a copy. When the competition starts, the school will arrange a bus to deliver the papers. You go to Xijing to participate in the competition."

"Jiang Jie, you have learned some things in the training class. Please share them with Lin Xiao and Xu Lin when the time comes. You can also discuss some questions together."

Listening to the teacher's arrangement, the three boys all said, "Okay, teacher."

"Well, then it's nothing, let's go."

Afterwards, the three students left the office.

After going out, Jiang Jie suddenly said to Lin Xiao and Xu Lin: "You don't need me to teach you, right? Since you don't even go to the training class, there's no need, and I don't have that much time."

Lin Xiao and Xu Lin looked at each other, and the former said: "No, I won't waste your time."

"That's fine, I'll leave first."

After saying that, Jiang Jie left quickly.

Xu Lin looked at Jiang Jie's back and complained: "Who wants him to teach me? I want to see if he can win the first prize."

Lin Xiao spread his hands: "That will have to wait a month. Let's learn from ourselves."

"Hmph, maybe we can win third prize, second prize or something without participating in the training class? I've searched online before, and no one in our school has ever won first prize. I still don't believe he can win it. "

Lin Xiao smiled and said, "We can just win the first prize. If we work harder, we can enter the winter camp."

At this point, Xu Lin was speechless and said calmly: "Forget it then. If I can pass the college entrance examination, I will be happy."

Lin Xiao shrugged and said no more: "Let's go here first and go back early for dinner."

Xu Lin nodded and separated from Lin Xiao.

Lin Xiao returned to the classroom, packed his schoolbag, and put all the five-three and other things into the schoolbag, especially the mathematics ones, he put them all in one go.

He will definitely participate in the league, and he will also take the exam well, and strive to get a place to go to the CMO winter camp.

Although the system gave him the mission of searching for the truth of the universe, getting some sufficiently commendable honors also meets his current needs.

As for why I refused to participate in the training, it was pointless.

With the truth aid, he can acquire knowledge significantly faster through self-study. Going to lectures is a waste of time.

…

In the next few days, Lin Xiao continued his studies.

Needless to say more about mathematics, he mainly reviewed in more detail some of the league's test syllabus.

At the same time, the class teacher did help him get some things handed out in the training class, including analysis of the league outline, various knowledge points, simulation papers, real test papers, etc., and also recommended a special book You have to buy the textbooks and exercise sets that explain the competition knowledge. Of course, Lin Xiao also bought the textbooks and exercise sets.

Through this kind of systematic learning, he can clearly feel that his mathematical knowledge is constantly improving.

At the same time, he also consciously studied advanced mathematics in his spare time.

He just bought the Tongji edition of Advanced Mathematics, a volume that all students majoring in science and engineering study, and it was also the book that caused countless college students to fail.

If high school mathematics is only a shallow water area, then Lin Xiao, who suddenly entered advanced mathematics, has undoubtedly entered a transitional area from shallow water to deep water.

And the kind of thinking ability that is used to kill people and kill Buddhas in high school mathematics has also become slightly slower because it began to accept new knowledge.

For example, in advanced mathematics, the expression form of derivatives becomes dy/dx, a notation passed down by Leibniz. As for f`(x) used in high schools, it is the Lagrangian method.

In addition, there are also some new theorems or formulas that he needs to be familiar with, such as Taylor's expansion, Lagrange's mean value theorem, Cauchy's mean value theorem, etc. These are all things that need to be learned after entering the first few classes of advanced mathematics in college. , at the same time, it also stumped countless college students.

Of course, this does not stump Lin Xiao.

For him, it is just a process of acceptance. With the help of the system, he can understand these new knowledge very quickly. After all, these things have not really entered the deep water area of ​​mathematics, and he is a college student.

In this way, time passed quickly and came to August 24th.

This week, the school officially started, and the first and second grade students have officially ushered in the new semester.

Today is Friday, and the senior year of high school also has a mock exam.

For senior high school students, one test a week and one test every two weeks are basically a normal rhythm. Through such frequent tests, students will not be nervous when they take the college entrance examination.

As for why there were no exams for more than half a month, it was because it was still the summer cram school period, so the school did not prepare them for the exam.

Therefore, this exam can be regarded as the first exam faced by this senior year of high school.

For Lin Xiao, this is also a test to test his learning results with the help of the system in the past half month.
