Originally, after Liao Zhixing learned that Cheng Nuo was snatched by their Tsinghua University, he very much hoped that Cheng Nuo would apply for their mathematics college.

After all, people who can still get full marks in the college entrance examination mathematics test paper issued by Uncle Ge must have an unusual talent in mathematics.

However, the sky was not as expected, Cheng Nuo did not apply for the mathematics department of Tsinghua University as Liao Zhixing expected, but went to the finance department, which made him regretful.

But Liao's trip can't force Cheng Nuo to come to their mathematics department, since Cheng Nuo's college entrance examination score is enough, it is his freedom to choose what major to choose.

Gradually, as time passed, Liao Zhixing left the name Cheng Nuo behind. I thought that I would never give this genius boy a chance to give a lecture in the future.

But he never expected that on the first day of his high school substitute class, he would meet Cheng Nuo.

Moreover, if it is not a coincidence that the book is not written, Cheng Nuo was called up and went to the podium to solve the problem.

This thing......

Liao Zhixing looked at Cheng Nuo with extremely puzzled eyes, and said in a strange tone, "Cheng Nuo, you seem to be a student of the Department of Finance, right?"

Cheng Nuo nodded with a wry smile, "Yes, that's right, my name is Cheng Nuo, and I'm from the Department of Finance." ”

Wow~~!

As soon as Cheng Nuo spoke, there was an instant uproar under the podium.

It's him!

That's him!

The pretending criminal, who pretends to be like the wind and often accompanies him-Cheng Nuo!

They are now almost certain that the person on the podium is that Cheng Nuo from the Department of Finance!

Although, all the people they are doing have not seen Cheng Nuo's true face. But on the rivers and lakes, the legend of Cheng Nuo has always been circulated.

The one who topped the science list with his strength, and Cheng Nuo, who had no defeat in the strongest brain!

Dumbfounded!

The students in the mathematics department looked at each other, and they immediately reacted to a fact.

If you say, Cheng Nuo on the podium is the Cheng Nuo of the Department of Finance.

So, it means that the people who just gave more than 30 new students in the mathematics department were not their classmates in the mathematics department.

Rather, it's a ...... Finance Students!

MMP!

Everyone in the mathematics department who realized it later, at this time, there was only one sentence in their hearts that they wanted to blurt out.

A group of people from the mathematics department asked a finance student who had nothing to do with their major to teach them math problems for half a day.

And they barely kept up with the pace of the talks.

This picture ......

Hiss –

It's very joyful to think about!

Everyone in the mathematics department twitched the corners of their mouths and looked at Cheng Nuo with an innocent face on the podium, not knowing what to say!

Liao Zhixing, who was standing on the podium, had a wonderful expression on his face at the moment.

I thought that Cheng Nuo was a good seedling in their mathematics department, and I planned to focus on cultivating it.

However, in the end, it was discovered. Cheng Nuo is a good seedling but not bad, but he is not from his own field. If you want to water and fertilize yourself, you can't go to other people's fields.

There are no more ups and downs in life than this.

"Then you came to this classroom, right?" Liao Zhixing asked slowly.

"Oh, that's right. Cheng Nuo pondered and forcibly explained.

I saw him say in a sincere tone, "Teacher, it's actually like this. Although I applied for the finance department of our school, I have always been obsessed with mathematics. I think I have a bit of talent in mathematics. ”

What Cheng Nuo said in this sentence is really ...... The whole class couldn't argue with it.

The only perfect score in mathematics in the college entrance examination, in terms of mathematical talent, must be much higher than ordinary people.

"Since I am fortunate to be admitted to Tsinghua University, I have the opportunity to receive the top higher education in China. Well, I certainly won't let my talent in mathematics go to waste. Mathematics and finance are both majors that I am passionate about. But why can't you have both? So, in my mind, the idea of skipping classes came to mind. ”

"By chance, I heard about you, Mr. Liao, and knew that you were one of the top gold medal lecturers in the mathematics college. So, with a kind of pilgrimage. I came to this classroom to listen to your lecture. ”

It is impossible to go to the wrong classroom if you go to the wrong classroom, and it is impossible to admit that you have gone to the wrong classroom in this life. You can only rely on forcibly explaining a wave to mix up this way.

Sure enough, after listening to Cheng Nuo's explanation, Liao Zhixing's face was full of red light, and he did not show the slightest intention to blame Cheng Nuo.

Some people like their own courses, and some people are willing to come to the class, which is undoubtedly the greatest affirmation of a teacher.

Liao Zhixing picked up the thermos cup and said with a smile, "Cheng Nuo, yes, very good." Although you are not a student of our School of Mathematics, this attitude of learning is very worthy of learning for our students in the School of Mathematics. ”

"Well, I'll talk to the other teachers in the math school, not only my senior substitute class, but even if it's other teachers' class, you can go to it casually. I'll ask them to add you to the class roster, roll call, ask questions, and assign homework, and they won't forget you!"

The corners of Cheng Nuo's mouth twitched violently, "Teacher, don't bother you." If you want to take a math class in the future, just sneak in, don't have to be so troublesome!"

"Hey, no, no. Liao Zhixing waved his hand, "It's rare to see Cheng Nuo, you like the students of our mathematics department so much, what is the trouble for our teacher." As long as you can learn and know, no matter how much trouble it is, it is worth the trouble! I know that some of the courses in your finance department and the courses in the mathematics department have conflicting schedules, but it doesn't matter, I will arrange classes for you according to your non-class schedule. ”

Cheng Nuo: "I ......"

Seeing that Cheng Nuo was still about to speak, Liao Zhixing raised his hand and stopped Cheng Nuo, "Don't refuse the teacher's kindness, if you want to thank me, study hard and strive to solve a world problem for me." ”

Cheng Nuo: "......"

With a smile on his lips and an MMP in his heart!

is talking about Cheng Nuo's mood at this time.

It can really be said to be a disaster without reason!

Inexplicably, a professional course was added, if Cheng Nuo was willing in his heart, it would definitely be fake!

But......

Even if I am not happy in my heart, I can't refuse now.

Ay~~

Cheng Nuo let out a long sigh.

I thought that after I went to university, I would not have to sit in the classroom every day to study like I did in high school.

However, now it seems that Cheng Nuo still has to continue his hard life!

............

was so made by Liao Zhixing, Cheng Nuo couldn't sneak away after the first advanced algebra class according to the original plan.

After sitting in the classroom and listening to two classes of high substitute classes, Cheng Nuo was relieved.

But......

Cheng Nuo knew that this was only the beginning of the suffering.

Two professional courses!

knew earlier that Cheng Nuo might as well confess honestly.

In the high math class of the Department of Finance, according to the messages sent by several roommates, the teacher did not name them in class, which made Cheng Nuo breathe a sigh of relief.

In the morning three or four sessions, there are no classes in the Department of Finance. In the afternoon, there is a lesson on management principles.

However, on the mathematics department's side, there is still a math class.

Although he was extremely reluctant, Cheng Nuo still obediently and skillfully went to the class.

Since he didn't know where the classroom was, Cheng Nuo could only follow behind his classmates in the mathematics department.

Suddenly, Zhao Yang, who was walking in front of the mathematics department, turned his head and saw Cheng Nuo behind him, and couldn't help but stop, waiting for Cheng Nuo to follow.

"Cheng Nuo, do you really plan to follow our mathematics department to take a math class?" Zhao Yang said.

Cheng Nuo shrugged, "What can I do, I'm also desperate, okay?"

"Then how did you come to our high substitute classroom in the last class?" Zhao Yang then asked.

"What if I say...... I accidentally walked into the wrong classroom, would you believe it?"

"......" Zhao Yang was speechless for a moment, "So, you didn't come here to skip the courses of our mathematics department?"

"Of course. If I like mathematics, I will apply to the mathematics department early when I fill in the college entrance examination. ”

"So, ...... question from Teacher Liao, a substitute teacher in the last section?"

"Oh, I just thought it was too boring to sit there, so I listened to the lecture for a while. As for the problem, I was idle and tried to solve it, but I didn't expect it to be quite simple. By the way, Zhao Yang, you should also think that question is very simple, right?"

Zhao Yang: "......"

Simple, simple yarn!

If it were simple, when the teacher asked people to come on stage to explain, he raised his hand.

If you pretend to be forced like this, you really won't be afraid of being caught at the police station!

Nothing to say all the way.

Indeed, plus the time he hit the target, Zhao Yang didn't know how many times he was choked by Cheng Nuo.

In the future, unless necessary, you must talk to Cheng Nuo less. Remember, remember!

The classroom for the Mathematics class is on the third floor of Building 13.

Cheng Nuo sat in the first row, and Zhao Yang was sitting next to him.

Zhao Yang glanced at Cheng Nuo next to him, and pushed the textbook on the table to Cheng Nuo's side.

"You don't have a textbook yet, so let's read one first. Zhao Yang said kindly.

Cheng Nuo: "Oh, no need. I'm different from you, I don't need a textbook, I can understand. ”

Zhao Yang: "......"

I'm really cheap!

Zhao Yang couldn't wait to slap himself with a big mouth.

said that he didn't talk to Cheng Nuo, but he still took the initiative to speak, and he deserved to be choked!

Five minutes before class, the teacher walked into the classroom.

A male teacher, the grade looks much younger than Liao Zhixing, only in his thirties.

Qi Ziyuan, this is the name of the teacher of Shufen, and he is still an associate professor. And Liao Zhixing, who taught Gao Dai, has the title of full professor.

However, there is no surprise that in Tsinghua University, teachers who are basically forty years old and above can be rated as professors. Those who can become academicians in their forties can be regarded as real demons!

The class bell rings, and the class begins!

Mathematical Analysis, like Advanced Algebra, is the most basic course in the Department of Mathematics.

Mathematical analysis and advanced algebra are the necessary foundations for other subsequent mathematics courses such as differential geometry, differential equations, complex functions, real functions and functional analysis, computational methods, probability theory and mathematical statistics.

Therefore, there is no room for slacking off in the mathematics department.

According to the routine, Mr. Qi first spent five or six minutes briefly introducing the course of mathematical analysis and the examination method. Then, let's get down to business.

It is different from Liao Zhixing's teaching method.

Liao Zhixing finished the first chapter in less than one class. Then I used to do the question, do the question!

Qi Ziyuan, on the other hand, spent two full classes analyzing the content of the book from beginning to end.

Then, Mr. Qi stood on the podium, held up the book with a light yellow cover of the number of points, and said with a smile, "Do you think that mathematical analysis is a book that mixes boring mathematical formulas and theorems, and talks about all kinds of differentiation, limits, and integrals?"

Everyone nodded in unison.

That's true. Not only mathematical analysis, but all mathematics professional books can be said to be boring and boring.

However, since the mathematics department has been chosen, everyone is naturally prepared to endure this boredom and tedium.

Teacher Qi smiled mysteriously and shook his fingers gently, "Actually, it's not what you think. ”

"Mathematical analysis is not only about mathematics, but also about ...... A full life!"

Hearing this, everyone in the audience was slightly suspicious.

Teacher Qi smiled slightly, turned around, drew a discontinuous function on the blackboard, and pointed to this discontinuous function and said.

"The pain of life is in pursuing the wrong things. The so-called pursuit of the wrong thing is when you approach it infinitely, and you suddenly realize that you are not continuous with it. ”

Teacher Qi drew a number line on the blackboard again.

"Man is not alone, just as there are infinite number of rational points on the number line, and you can find your partner in any small neighborhood of yours. But people are lonely, just like after marking the unreasonable points of the entire number line, no one can see it. ”

Mr. Qi drew two functional curves of F(x)=x and F(x)=x^2 on a coordinate axis.

"The relationship between man and fate is like the relationship between F(x)=x and G(x)=x^2. At first, you think that fate is your infinitesimal quantity. As you get older, you realize that you can't keep up with your fate, even with all your might. At this time, if you either go down in a humble manner, you will end your life. ”

After talking about these three life philosophies hidden in the number of points, Qi Ziyuan looked at the podium with a smile, and thought deeply about everyone.

"The philosophy of life in the number of points is definitely more than that. Who's going to come up and say another one?"

"Come on, just that chubby classmate!"

The chubby Li Xiurui stood up again with a confused face. "Teacher, I won't. ”

"Then you sit down first. Qi Ziyuan motioned for Li Xiurui to sit down, his eyes looked around the classroom, and finally landed on Cheng Nuo in the first row. "You are Cheng Nuo from the Department of Finance mentioned by Professor Liao, right?"

Sure enough, Mr. Liao's efficiency is really fast!

It is estimated that it will not be long before he becomes a well-known figure among the teachers of the mathematics college.

At that time, it will be the beginning of his tragic life.

Cheng Nuo, whose face was not very good-looking, nodded, "Well, teacher, it's me." ”
