Chapter 210

After the sixth day of the Lunar New Year, some Yan University students have begun to return to school.

Ma Zhengxuan is one of them.

The reason for his return to school was simple: to train for the National Collegiate Mathematics Competition.

After returning to school, Ma Zhengxuan went to Gu Lu's office for the first time.

"Is it okay to have a good year?"

Gu Lu was working on the opening report of a new topic in the office at this time, and when he saw Ma Zhengxuan knocking on the door and coming in, he smiled and beckoned Ma Zhengxuan to sit down.

Ma Zhengxuan sat opposite Gu Lu stiffly, scratching his head, "It's okay." ”

"That's right. Ma Zhengxuan took out a stack of test papers from his schoolbag and handed them to Gu Lu, "I have completed these ten sets of mock questions you gave me during the winter vacation." ”

These ten sets of mock questions for the National College Student Mathematics League were handed over to Ma Zhengxuan by Gu Lu when he was leaving last semester.

The purpose is to test Ma Zhengxuan's self-study results. Therefore, among the ten sets of simulation problems, complex variable functions and ordinary differential equations are the most numerous.

Gu Lu took it, flipped through it roughly, and found that most of the answers were correct.

Gu Lu nodded with satisfaction, "I'll review it for you, and come over tomorrow to get it." ”

"Your competition coaching is going to start tomorrow?" Gu Lu then asked.

Regarding the National Collegiate Mathematics Competition, since the college did not assign any work related to Gu Lu, Gu Lu did not deliberately pay attention to it.

"Well, tomorrow morning, we will gather in the lecture hall on the first floor of the building of the Institute of Mathematics to carry out unified counseling. Ma Zhengxuan replied.

"That's ......" Gu Lu's fingers tapped lightly on the table irregularly, "The National College Student Mathematics Competition starts on March 12th, and you probably have more than a week to prepare." ”

"You're going to have to make the most of the week. Strengthen the strengths and make up for the weaknesses. Especially for the content of complex variable functions and ordinary differential equations, if you have any questions that you don't understand, feel free to ask your competition tutor, or come to me, I usually stay in the office from now until the start of school. ”

Ma Zhengxuan nodded gratefully, "Thank you, teacher!"

Gu Lu waved his hand, indicating that he didn't have to be so polite.

"One more thing. Gu Lu leaned forward and his eyes fell on Ma Zhengxuan, "Are you still doing that tutoring job?"

Ma Zhengxuan shook his head, "I'm not doing it, the grades of the senior high school student I worked as a tutor have already gone up, and I don't need my tutoring anymore, so I took the initiative to resign." ”

"I plan to find a new job as a tutor when school starts. ”

Ma Zhengxuan's 1510 answer.

The salary of tutoring is the main source of Ma Zhengxuan's living expenses, and he is now self-sufficient, and can even subsidize the family from time to time.

In Ma Zhengxuan's plan, he is going to be busy with the National University Student Mathematics Competition, and then find a tutor job.

Gu Lu rubbed his chin, pondered for a few seconds, and suddenly asked, "Zhengxuan, do you want to follow me?"

Ma Zhengxuan was stunned for a moment, his eyes were puzzled, and he didn't quite understand what Gu Lu meant, "Teacher, what do you mean?"

"That's right. Gu Lu smiled and said, "Recently, I was preparing to open a new topic, and there are a few people who are missing, Zhengxuan, do you have any intention of coming over to help me." ”

"Of course, the salary is there, even higher than your salary as a tutor, but it is estimated that it is much more tiring than your tutor. I'm here to ask for your opinion, whether to continue as a tutor or to come to me. Gu Lu stared at Ma Zhengxuan with burning eyes.

"I choose to follow the teacher!" Ma Zhengxuan stood up and replied without hesitation.

It's just that after answering, Ma Zhengxuan's whole person became uneasy, "Teacher, can I, can I really go over and follow you?"

He is only a first-year undergraduate, and the project that Mr. Gu is researching, without even thinking about it, must be quite difficult.

He was a little worried that he couldn't help Teacher Gu at all.

Gu Lu knew Ma Zhengxuan's worries, smiled slightly, got up and patted Ma Zhengxuan's shoulder, "You have to believe in yourself." Let me ask you, have you finished all the textbooks for your college math major?"

Ma Zhengxuan nodded, "I've finished previewing." ”

"That's enough. Don't overestimate yourself and don't look down on yourself. Your current level of math may not be lower than that of a senior student. Besides, I won't give you tasks beyond your level, and besides, it's not me, is it? ”

"Well, teacher, I remember!"

"The specific time and place, I will inform you on WeChat, but it should be a period of time after the start of school, don't worry, at this stage, you still have to prepare for the National Collegiate Mathematics League. ”

"Teacher, may I ask a question?"

"Just ask. ”

"What is the research topic of our group?"

"Proof of BAB's conjecture!" Gu Lu gently spit out these words.

…………

Let Ma Zhengxuan come over and give him a hand, Gu Lu had already thought about it.

Of course, in addition to Ma Zhengxuan, there is also Bi Qi, who is also included in the consideration of Gu Lu.

But in the end, Bi Qi couldn't get over, and he still had to consider Bi Qi's own opinion.

This matter is not clear on WeChat, so I can only wait for the start of school to talk to Bi Qi.

However, it is still necessary to give advance notice,

"When you get back to school, come to my office. Gu Lu is >

After more than half an hour, Bi Qi replied to Gu Lu's message, "OK." ”

"What are you doing?" Gu Lu asked idly and boredly.

Bi Qi sent a loveless emoji and replied to Gu Lu, "Tutoring my little cousin in his homework." Teacher, I feel like I'm about to have a cerebral hemorrhage because of my anger. ”

Haicheng, Bi Qi's home.

Bi Qi took the winter vacation homework done by the little cousin next to him, grinding his teeth, and looked like he was about to beat someone.

He was really going to be.

Ancient Chinese Translation: Isn't My Shot Perfect?

The correct translation should not be, "Isn't my archery skill masterful?"

But what about his little cousin's translator: "Isn't it Jingzi that I shot?"

!

Is this the answer that a man can come up with?

And this one.

[In class, Mr. Wang gave everyone such a problem, when x=-1, find the value of algebraic formula 2(x^2-1/2+2x)-4(x-x^2+1). Xiao Ming looked at it and said, "It's too complicated, what should I do?", can you help Xiao Ming solve this problem? Please write down the specific process. 】

Answer: Xiao Ming, you have to think independently. Can't rely on others!

Biqi: "¥#%*&%"

"Cousin, what's wrong with you?" the little cousin looked up and tugged at Bi Qi's clothes.

"Nothing. Bi Qi rubbed his eyebrows and took a deep breath, "Didn't your parents scold you at home for this homework you did?"

"I scolded before, but I don't scold recently. The little cousin replied innocently, "They just said that the number practice is useless." I want to delete the number and rehearse, I don't know what it means. ”
