Chapter 225 "Mathematical Analysis", a book containing the philosophy of life
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 School of Mathematics.

After all, a person who can still get full marks in the mathematics test paper of the college entrance examination issued by Uncle Ge must have a talent that is different from ordinary people in the subject of mathematics.

But as one wished, Cheng Nuo did not apply for Tsinghua's Department of Mathematics as Liao Zhixing expected, but went to the Department of Finance, which made him very regretful.

But Liao Zhixing couldn't force Cheng Nuofei to come to their mathematics department. Since Cheng Nuo had enough college entrance examination scores, it was his freedom to choose a major.

Gradually, as time went by, Liao Zhixing forgot about the name Cheng Nuo.I thought I would never have the opportunity to give lectures to this talented young man again.

But he never expected that he would meet Cheng Nuo on the first day of his senior class.

Moreover, as a coincidence, 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, "Classmate 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 uproar under the podium.

It's him!

it's him!
That pretentious criminal who is always with him—Cheng Nuo!
They were almost certain now that the person on the podium was Cheng Nuo from the finance department!
Although, everyone they were doing didn't see Cheng Nuo's true face.But in the Jianghu, the legend of Cheng Nuo has been circulating.

That Cheng Nuo who topped the list of science subjects with his strength, and that Cheng Nuo who had no defeat in the strongest brain!
Dumbfounded!Completely dumbfounded!
The students in the Department of Mathematics looked at each other and immediately realized a fact.

If we say that Cheng Nuo on the podium is the Cheng Nuo from the finance department.

Then, it means that it was not their classmates who taught math problems to more than 30 freshmen from the math department.

It's...a student from the finance department!
MMP!

Everyone in the Department of Mathematics, who was belatedly aware, only wanted to blurt out a sentence in their hearts at this time.

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

And they almost couldn't keep up with the rhythm of the lectures.

This picture...

hiss--

It makes me happy just thinking about it!

Everyone in the Department of Mathematics looked at the innocent Cheng Nuo on the podium with their mouths twitching, not knowing what to say!
Liao Zhixing, who was standing on the podium, also had a wonderful expression on his face at the moment.

I thought Cheng Nuo was a good seed in their mathematics department, so I planned to focus on cultivating it.

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

The ups and downs of life are nothing more than this.

"Then you come to this classroom, are you?" Liao Zhixing asked slowly.

"Oh, that's right." Cheng Nuo mulled over and forcefully explained.

He said in a Chen Ken tone, "Teacher, it's actually like this. Although I applied for the finance department of our school, I have always been obsessed with the subject of mathematics. I think about it day and night, and I can't sleep day and night! I think, I'm still a bit talented in the subject of mathematics."

What Cheng Nuo said was really... The whole class couldn't refute it.

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

"Since I am lucky enough to enter Tsinghua University and have the opportunity to receive top higher education in China, then I will not let my talent in mathematics be lost in vain. Mathematics and finance are both majors I love. But why do the two Is it impossible to have both? So, in my mind, I came up with the idea of ​​taking classes."

"Once again by chance, I heard about you, Mr. Liao, and knew that you are one of the best gold medal lecturers in the School of Mathematics. So, with a feeling of worship. I came to this classroom and listened to your teacher. Lecture."

It is impossible to go to the wrong classroom, and it is impossible to admit that you have gone to the wrong classroom in this life.It can only be confused by a wave of forced explanations.

Sure enough, after listening to Cheng Nuo's explanation, Liao Zhixing's face was flushed, and he didn't show the slightest intention to blame Cheng Nuo.

Some people like your courses and some are willing to take classes. This is undoubtedly the greatest affirmation for a teacher.

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

"How about this, let me tell the other teachers in the School of Mathematics, not only my senior class, but also other teachers' classes, you can take whatever you want. I will let them add you to the roster of classes, and call the class , asking questions, assigning homework and so on, I won’t forget you!”

The corner of Cheng Nuo's mouth twitched violently, "Teacher, I don't need to bother you. If you want to take classes in the mathematics department in the future, you can just sneak in, and you don't need to be so troublesome!"

"Hey! No trouble, no trouble." Liao Zhixing waved his hand, "It's rare to see Cheng Nuo, you like our mathematics students so much, our teacher is so troublesome. As long as you can learn and know, no matter how troublesome it is, it's worth it Yes! I know that your Finance Department courses and Mathematics Department courses sometimes conflict with each other, but it doesn’t matter, I will arrange courses for you according to your no-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, just study hard and try to solve a world problem for me."

Cheng Nuo: "..."

Grinning on the mouth, MMP in the heart!

What he was talking about was Cheng Nuo's mood at the moment.

Unexpected disaster!It can really be said to be an indiscriminate disaster!
A professional course was added to the program inexplicably. If Cheng Nuo was happy with it, it would definitely be a lie!
but……

Even if I don't like it in my heart, I can't refuse now.

hey~~
Cheng Nuo let out a long sigh.

I thought that after I went to college, I wouldn't have to sit in the classroom to study every day like high school.

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

…………

Being called out by Liao Zhixing, Cheng Nuo couldn't follow the original plan and sneak away after the first advanced algebra class.

Cheng Nuo was relieved after sitting in the classroom with extremely painful balls and listening to two advanced classes.

but……

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

Two professional courses!

If he had known earlier, Cheng Nuo might as well have confessed honestly.

In the advanced mathematics class of the finance department, according to the news sent by several roommates, the teacher did not take roll call in the class, which made Cheng Nuo heave a sigh of relief.

In the third and fourth quarters in the morning, there are no courses in the Finance Department.In the afternoon, there is a section on principles of management.

However, in the Department of Mathematics, there is still a Mathematics class.

Although he was extremely reluctant, Cheng Nuo obediently went to the math class.

Since he didn't know where the mathematics classroom was, Cheng Nuo could only follow behind the students 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. He couldn't help but stop, waiting for Cheng Nuo to follow.

"Cheng Nuo, are you really planning to follow our mathematics department to take the math class?" Zhao Yang asked.

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

"Then how did you come to the classroom of our senior class last class?" Zhao Yang continued to ask.

"Would you believe me if I said... I accidentally walked into the wrong classroom?"

"..." Zhao Yang was speechless, "So, you didn't come here to take courses in our mathematics department?"

"Of course. If I liked mathematics, I would have applied to the Department of Mathematics when I filled out the volunteers for the college entrance examination."

"So, the question given by Mr. Liao in the last class...?"

"Oh, I just thought it was too boring to just sit, so I just listened to the class for a while. As for the problem, I just had nothing to do and tried to solve it. I didn't expect it to be quite simple. By the way, Zhao Yang, You should also think that question is easy, right?"

Zhao Yang: "..."

Simple, simple yarn!

If it was simple, when the teacher asked people to come to the stage to explain, he would have raised his hand.

If you pretend to be aggressive like this, you really won't be afraid of being caught by the police station!
Speechless all the way.

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

From now on, unless necessary, you must talk to Cheng Nuoshao.Remember, remember!

The classroom for counting classes 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 who was next to him, and pushed the score textbook on the table towards Cheng Nuo.

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

Cheng Nuo: "Oh, no need. I'm different from you. I can understand without a textbook."

Zhao Yang: "..."

Mouth cheap!I'm so cheap!

Zhao Yang wished he could slap himself in the face.

He agreed not to talk to Cheng Nuo, but he still took the initiative to speak up, he deserved to be choked up!

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

A male teacher, the grade looks much younger than Liao Zhixing, only in his 30s.

Qi Ziyuan, this is the name of the teacher of several minutes, and he is currently an associate professor.And Liao Zhixing, who teaches Gaodai, has the title of full professor.

However, there is no surprise. At Tsinghua University, almost all teachers aged 40 and above can be awarded the title of professor.Those who can become academicians in their 40s are truly evil!

The class bell rings, and the class begins!
The subject "Mathematical Analysis", like "Advanced Algebra", is the most basic course in the mathematics department.

Learning mathematical analysis and advanced algebra well is the necessary basis for learning other subsequent mathematics courses such as differential geometry, differential equations, complex variable functions, real variable functions and functional analysis, calculation methods, probability theory and mathematical statistics.

Therefore, there is no room for everyone in the mathematics department to slack off.

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

It is different from Liao Zhixing's teaching method.

Liao Zhixing finished Chapter 1 in less than one class.Then use it to do the questions, do the questions!

Qi Ziyuan, on the other hand, spent a full two classes time reading the content of the mathematical analysis book from beginning to end.

Then, Mr. Qi stood on the podium, held up the light yellow leather-covered Score I, and said with a smile, "Do you think that mathematical analysis is a book mixed with boring mathematical formulas and theorems?" , are you talking about various differentials, limits, and integrals?"

Everyone nodded in unison.

Indeed it is.Not just mathematical analysis, it can be said that all professional mathematics books are boring and boring.

However, since they chose the Department of Mathematics, everyone was naturally prepared to endure this kind of boring and boring.

Teacher Qi smiled mysteriously and shook his finger gently, "Actually, it's not what I thought."

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

Hearing this, everyone in the audience was suspicious.

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

"The pain in life lies in the pursuit of the wrong thing. The so-called pursuit of the wrong thing means that when you approach it infinitely, you suddenly discover that you and it are not continuous."

Teacher Qi drew another number line on the blackboard.

"People are not lonely, just as there are infinite rational points on the number axis, and you can find your partner in any small neighborhood of you. But people are lonely, just as after marking the irrational points on the entire number axis, I can’t see anyone.”

Teacher Qi draws two function curves of F(x)=x and F(x)=x^2 on one coordinate axis.

"The relationship between people and fate is like the relationship between F(x)=x and G(x)=x^2. At the beginning, you think that fate is your infinitesimal quantity. As you grow older, you find that you are exhausted. No effort can keep up with the pace of fate. At this time, if you don’t walk down with a humble attitude, you will end your own life.”

After talking about these three life philosophies hidden in the few minutes, Qi Ziyuan smiled and looked down the podium, thinking deeply about everyone.

"The philosophies of life in the score must be more than these. Who will come up and say another one?"

"Come on, just that fat classmate!"

The chubby Li Xiurui stood up again in a daze. "Teacher, I won't."

"Then sit down first." Qi Ziyuan motioned for Li Xiurui to sit down, looking around the classroom and finally landing on Cheng Nuo in the first row. "Are you the student Cheng Nuo from the Department of Finance whom Professor Liao mentioned?"

Sure enough, Teacher Liao's efficiency is really fast!
It is estimated that in a short time, I will become a well-known figure among the teachers of the Mathematics College.

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

Cheng Nuo nodded with an uneasy face, "Well, teacher, it's me."
