Xueba starts with change

Chapter 120 The Exam Season is Coming

Naturally, Fang Jieming didn't believe Chen Zhou's words. He said directly: "It's not up to you to decide whether to be cheated or not. I don't want to put the result of the competition on the two of you."

After a pause, Fang Jieming continued: "I will be in charge of the theoretical calculation part, which is connected with the construction of the model."

Chen Zhou and Yang Yiyi looked at each other, he didn't want to fuss over this matter, so he said, "Yes, but I have one condition."

Fang Jieming asked, "What conditions?"

Chen Zhou replied: "I will also do the theoretical calculation part. In the end, we will compare and choose which one to use for programming."

Fang Jieming was taken aback for a moment, then nodded immediately.

Although it is not harmonious, it also divides the tasks.

The next step is to wait for the specific running-in training before making adjustments.

Chen Zhou thought for a while and said to Fang Jieming: "Senior, since we are already in the same team, I still hope that we will work together."

Glancing at Chen Zhou, Fang Jieming said, "Don't worry about that."

Chen Zhou smiled, and turned to Yang Yiyi and said, "Yiyi, let's go."

Yang Yiyi nodded, and the two wanted to leave.

Fang Jieming glanced at the two of them, and asked a question that seemed strange to him: "Why did you participate in this competition? It stands to reason that you are a freshman in the Department of Mathematics and have never participated in a competition, so she shouldn't ask you to be a teammate? "

Hearing this, Chen Zhou and Yang Yiyi looked at each other and smiled, Yang Yiyi answered the question: "He is my boyfriend."

"Oh. Ah?" Fang Jieming froze in place.

When Chen Zhou and Yang Yiyi left the classroom, Fang Jieming came to his senses, did he feel that he was being used as a light bulb?Getting cheated before the competition even started?
He directly took out his cell phone and dialed Shen Jing's number.

On the way back to the dormitory, Yang Yiyi looked at Chen Zhou and asked, "Why did you say that on purpose? Didn't we already discuss and reasonably allocate the work of the three people?"

Chen Zhou smiled softly and explained: "This senior's mentality is a bit too arrogant. No matter how reasonable the distribution is, he will feel that we will be hindered. Instead of doing this, it is better to treat him as a tool man and let him take the initiative. , it would be even better.”

"Well, it seems quite reasonable." Yang Yiyi was thoughtful.

Chen Zhou added: "In the following running-in training, let's adjust our respective positions."

Yang Yiyi nodded.

Chen Zhou rubbed Yang Yiyi's head with a smile: "You still said I did it on purpose, didn't you also do it on purpose?"

Yang Yiyi smiled narrowly, pouted and said, "I'm just telling the truth."

In the next two days, the competition trio did not meet again, and Fang Jieming did not actively contact Chen Zhou and the others.

Chen Zhou and Yang Yiyi are still enriching themselves according to their own rhythm.

Topics and topics, topics and brushing books, brushing books and competitions.

This is a cycle, and Chen Zhou is immersed in this cycle, enjoying himself.

After Wu Xiping thoroughly verified the problems of the subject, he reissued some materials.

Generally consistent with Chen Zhou's judgment, the subject lacks actual scenarios.

Although it was delayed for a few days because of this incident, the time limit for the subject set by Wu Xiping was not extended.

In other words, Chen Zhou and the others only have less than a week left.

Moreover, Chen Zhou is about to usher in his first midterm exam at Yanda University.

Then came the first run-in training of the weekend.

Time is not tense.

Fortunately, Chen Zhou did not completely slow down the progress of the project before.

When the overall idea is correct, it is only necessary to re-substitute the calculated data.

Friday, January 11th.

The School of Mathematical Sciences of Yenching University officially entered the midterm exam season.

This morning, it was the first exam for the students of the Department of Mathematics, Mathematical Analysis 1.

The examination room is the large classroom where Wu Xiping usually attends classes, and the invigilator is the counselor Huang Yemei.

Chen Zhou entered the examination room almost at the time when the examination started.

Because Li Li and the others came over early, no one reminded him.

And he, immersed in a problem of the subject, had a continuous train of thought, and accidentally overdid it.

It wasn't until he solved the problem that he glanced at his watch, and quickly ran over with a fountain pen.

Fortunately, the invigilator was Huang Yemei, so he wasn't counted as late.

Walking quickly to the seat and sitting down, Chen Zhou took a few deep breaths to calm down his breathing that was too fluctuating due to trotting.

When passing the papers, the students in the back row glanced at Chen Zhou, thinking that the master of the subject would also be nervous?
Of course, he automatically ignored the reason why Chen Zhou came so late.

There are 1 major questions in the mid-term exam with a score of 7, the full score is 101 points, and the exam time is 110 minutes.

Chen Zhou glanced at the test paper briefly, and found that this topic was much simpler than the topic of Wu Xiping's contention.

The first major question is to judge whether the following limits exist, a total of 30 points, divided into 3 small questions.

Chen Zhou thought for a while, saving the draft paper, and started to answer directly.

Very smooth thinking, did not take much time, all resolved.

The second major question, proving the continuity of functions, has a total of 36 points and 4 small questions.

Chen Zhou glanced at the question, but he didn't know who wrote the test paper. Is it necessary to turn one question upside down and make 4 questions?
In Chen Zhou's view, these 4 small questions only use one knowledge point, and they are all sub-questions.

However, in order to prevent myself from falling into some traps due to carelessness.

When Chen Zhou finished these 4 questions, he checked them carefully.

After confirming that it is correct, move on to the next question.

It is a question of proving the existence and evaluation of the limit of the sequence, worth 10 points.

Chen Zhou thought for a while, starting with the increase of the sequence {an}, and then proving that the sequence is bounded, then there must be a limit A.

In that way, the limit can be obtained by setting {bn}, and then the limit A can be obtained.

With a firm mind, the pen in his hand fell on the test paper, and the answer came out naturally.

The next question is also a 10-point question, and the next question is a 5-point question.

It's all proof questions, simple.

The last two questions are left, both of which are worth 5 points.

The score is not very high, but this is the real distinguishing question.

Chen Zhou looked at the questions and found that they were more difficult than the previous ones.

He looked up at the counselor Huang Yemei who was sitting on the podium.

Huang Yemei was also looking at him.

Chen Zhou smiled at Teacher Huang, bowed his head and began to solve the problem.

After solving the sixth question, there is still the final finale question.

The topic is very simple.

"Assume that f(x) is a continuous function defined on the real number axis R with the smallest positive period as the irrational number μ (μ>0), prove that when n→+∞, the limit of the sequence {f(n)} does not exist."

Although it is a test with a score of 1, the knowledge points that can be used in this question are obviously not the content of mathematical analysis.

Chen Zhou thought of a corollary of the so-called Dirichlet approximation theorem in number theory.
