Reshaping life starting from the Junior Class of HKUST

Chapter 57
"Azhe, how about you saying that I want to create an automatic stock analysis and trading system?" Wang Chao touched his chin and said.

"Heh, are you short of money?" Wu Zhe didn't expect that the automatic stock analysis system that Wang Chao worked out in his previous life would have signs of it now.

"Hey, if you don't lack money, you can't think about making money? I have no enmity with money." Wang Chao looked at the three of them triumphantly.

"I like you!" Wu Zhe came over with a smile and patted Wang Chao's shoulder.

"I like you!" Huang Minghai also came up and patted Wang Chao.

"I like you!" When Shen Zhiwen finished speaking, the three of them looked at him at the same time. This must be fake Shen Zhiwen!

Shen Zhiwen looked at the three of them, but he paused in the air before he caught Wang Chao's hand.Then he retracted calmly and said, "Be gregarious."

Wu Zhe and Huang Minghai looked "hahaha" straight and happy.

Wang Chao said that MMP doesn't know whether to scold him, so there is no good person.

But the idea of ​​getting a stock software was buried in Wang Chao's heart.

------

The time came to Wednesday, and the class this morning was calculus, and the lecturer was Professor Yuan Shuwen from the School of Mathematics, University of Science and Technology of China.The venue is the public lecture hall on the East Campus.Because it is a compulsory course for all freshmen.Therefore, several classes are taught together.

Today is the School of Physics, and several classes from the School of Chemistry and the School of Chemistry are together for the first time in calculus.

The four of Wu Zhe took their backpacks and left the dormitory together.

"Wu Zhe, where are you going? I have class in East Room 201 today. You are going in the wrong direction." Huang Minghai hurriedly shouted seeing Wu Zhe in front of him going in the wrong direction.

"I know, I'm not going to go, I'm going to Xiabei Campus." Wu Zhe stopped, turned to Huang Minghai and said three people.

The three of them were stunned for a moment when they heard Wu Zhe's answer, what was going on?
"It's not good to skip class for the first time in Professor Yuan's class, right? Where are you going? I'll accompany you if it's fun." Wang Chao asked Wu Zhe.

"Well, I just checked. The Archeology Department of the North Campus is a class of Academician Qiu Gongjie of the Academy of Social Sciences today. You also know that there is only one archeology in our school's liberal arts. Usually, it focuses on testing and analysis. It is rare to have a literature and history class. The experts are here. I am interested in the content." Wu Zhe explained.

"Hehe, pretend I didn't say it." Wang Chao said with a haha.

The people in the dormitory knew that Wu Zhe liked ancient Chinese, and they often saw him reading those weird things.

It's just that Huang Minghai was still a little worried and said, "Azhe, don't you know how to call names?"

"It's okay, there are so many people, just call the roll call for me. Anyway, we have all learned calculus, so it doesn't matter if you listen or not."

After Wu Zhe finished speaking, he replied: "If you don't skip classes in college, is it still called college? Okay, I'll go first, and I have to catch a car to go to the North Campus."

Seeing Wu Zhe walking away, the three of them also went to the class place.Along the way, I met many classmates in the class, and asked Wang Chao why they didn't see Wu Zhe.A few people also casually blurted the past.

Entering the lecture hall, Professor Yuan Wenshu was already standing on the podium.Wang Chao raised his hand and looked at his watch and said softly to the two people around him: "It's not time for class yet! Are you so serious and responsible?"

Huang Minghai and Shen Zhiwen ignored Wang Chao, and the three found a corner to sit down.

Professor Yuan ignored the students who came in in twos and threes, and looked down at the handouts.Originally, this kind of basic course was taught by teaching assistants or lecturers, probably for a good start.The school arranged for him, the professor, to come to the first class.

He can only familiarize himself with the lecture notes first, after all, he hasn't taught the basics for a long time.

As soon as the bell rang, Professor Yuan also closed the lecture notes.He looked up at the students who were sitting full.

He patted the microphone on the podium and said in a loud voice: "Students, class is on. I believe that you will not miss the first class! The roll call will not be held today. I am Yuan Wenshu from our school's School of Mathematics. If you have any questions about calculus, you can go directly to the 302 teaching office of the number institute to find me."

The three of Huang Minghai were also relieved after hearing Professor Yuan's lecture. They are all good students, and they haven't skipped classes yet?Hearing no name-calling, they all subconsciously relaxed.

"What is calculus? Many students have asked this question. I can tell you that it is a tool, a mathematical tool. It was a mathematical tool invented by Newton to solve problems in mechanics. Let me talk about how Newton used calculus. Points are used to find the limit..."

Although the three of Huang Minghai had studied calculus, they still admired Professor Yuan's lectures. He put each formula into each celebrity story, which was particularly impressive.

And as the explanation gradually deepened, from the creation of Newton's calculus at the beginning, Cauchy used calculus to push irrational numbers.Let's talk about the Riemann integral.It contains limit derivation, Lagrangian mean value theorem, Cauchy mean value, Taylor formula and so on.

The knowledge that was originally boring was vividly explained by him.Huang Minghai and the three listened with gusto. They had already mastered all this knowledge. Although Professor Yuan spoke vividly and easily, the knowledge points basically included all the knowledge points of calculus (1).You didn't learn it in advance, you just listened to the story, and you didn't understand the knowledge points in it.

Professor Yuan looked at the time, then stopped and continued the lecture: "Let's talk so much on the first day of today! I will come up with a problem later, and let the students come up and solve it on the spot. Let's see how you master it?"

After finishing speaking, he turned around and started writing questions on the blackboard:
"Assuming that f is continuous on the interval [-1, 1], there are two points a and b on the interval, if f is a polynomial less than or equal to 3, the integral of f(a)+f(b)=f(x), the integral Superscript 1, subscript -1, what can you get from a and b?"

After finishing writing, he turned around and said to the students below, "Who will try?"

Everyone looked at the topic above, frowned and thought, Huang Minghai and Shen Zhiwen looked at Wang Chao and said, "How about it, are you sure? Ah Zhe is not here, I guess you are the strongest."

Wang Chao stared at the test question and said: "It's not that simple. This question looks simple but is actually very difficult. I might think about it for a while."

"Not only do we need to use the previous knowledge, but we also need to use Gaussian integrals and so on. This professor is too bad, this is not something that can be done at the freshman level. Whoever can solve this problem has the level of a graduate student in mathematics. .” Wang Chao pouted after thinking for a while.

"No one has come to try it yet! Then I'll call someone directly! The squad leader of Class [-] of the Junior Court will come up and try it."

As soon as the words fell, Huang Minghai and the three of them thumped in their hearts: "It's broken."

Seeing that no one responded, Professor Yuan said again: "Why, the junior courtyard is full of geniuses. The monitor of class 1 doesn't even have the courage to come up." Turning around, he looked for the roster, and on it was the position of monitor of class 1 written " Wu Zhe".

"Wu Zhe, who is Wu Zhe? Come on, come up and do it, it doesn't matter if you make a mistake." Professor Yuan said with a smile, he just came to show his authority, the more afraid he is, the happier he is.

"Who is Wu Zhe, stand up and let me see." Professor Yuan continued.

There was no other way, the three of them gritted their teeth and stood up at the same time.Then the three of them were stunned at the same time, and their eyes exchanged with each other.

"Why didn't you bother at first?" This was Huang Minghai.

"What should we do now?" Wang Chao asked.

"It's cool." This is Shen Zhiwen.

The point is that not only the three of them pretended to be Wu Zhe and stood up.

A total of more than 20 people stood up on the side of the juvenile courtyard.

There was also a woman among them, Qi Ming, secretary of the Communist Youth League.

Professor Yuan was a little dumbfounded seeing this situation.

The students around me were also stunned. Is the first calculus class so exciting?
