Chapter 68 Dimensionality Reduction Strike (Part [-])
"Shen You'an, you come up to answer this question."

The girl was lying on the table, as if she had fallen into a coma.

On the podium, Chen Zhou's face was ashen, and with chalk in his hand, he threw it at Shen You'an in the corner.

The whole class turned their heads to look at the same time.

Many of them gloated in their misfortune.

Unexpectedly, Shen You'an was also caught by Teacher Chen when she deserted in class. This time she will be in a terrible situation.

Chen Zhou, graduated from the Mathematics Department of Tsinghua University, studied under the famous mathematician Academician Jiang Han, Chairman of the National Mathematical Association, and has a pivotal position in the domestic mathematics field. Lanya Group has paid a lot behind the scenes for being able to recruit him to teach Class A effort.

One of his lessons is hard to find.

How dare someone sleep in his class, the critical Chen Zhou can imagine how angry he is.

Gu Bichen coughed lightly, and lightly touched Shen Youan's arm.

"Student Shen, wake up quickly."

The chalk tip hit Shen Youan on the head, and Shen Youan finally woke up faintly, and raised his head.

There were a few red marks on the side of the face, but the rest of the skin on the face was too pale and bloodless.

Liu Runxi, who turned her head, saw this scene, her eyes darkened slightly behind the lens, and she turned back calmly.

"Shen You'an, come up to me, if you can't solve this problem, go home and sleep."

Chen Zhou slapped the table and roared angrily.

Shen Youan pushed his glasses on the bridge of his nose, got up in front of the whole class, left his seat calmly, and walked to the podium.

Gu Bichen looked at her worriedly: "Student Shen...."

Passing by Liu Runxi's desk, Liu Runxi lowered his voice and said a word.

Yan Lu glanced at her deskmate in surprise.

The two sat at the same table for two weeks, but this one didn't say a word to her, it seemed like he was going to be immortal.

But he actually took the initiative to remind Shen Youan.

Shen Youan walked to the podium and glanced at the guide questions on the blackboard.

After a little thought, I picked up a piece of chalk on the podium and began to answer questions.

Chen Zhou stood aside with folded arms, watching coldly.

The teaching method of Lanya High School is different from the basic education of other high schools. The teaching pace is very fast, and it will be very difficult if you can't keep up with it. What you are waiting for is to fall out of Class A.

The students in the class basically previewed the content of the first volume of the first year of high school during the summer vacation, and even the gold medal tutor hired was already teaching the content of the second year of high school. This class is like this.

And his way of teaching is also more casual, he talks about what he thinks of, regardless of whether the students understand or not.

The so-called genius class must have the characteristics of a genius. What's the point of going step by step?
The abstract nature of mathematics requires students to give full play to their imagination and construct rigorous logical thinking in that vast space. This is a process that requires long-term training.

After his careful observation, these students have received this kind of mathematics training since childhood, so as long as they are not unintentional, they can basically keep up with it.

However, if there is a gap in a class, it will be like dominoes, a vicious circle.

He will never allow this to happen to the students he teaches, disrespect him and mathematics.

The derivation formula taught in this class is obviously beyond the outline, and it involves the calculus of advanced mathematics in colleges. The upcoming mathematics entrance examination usually involves this knowledge, so he will talk more about it.

Shen You'an is indeed a genius, but no matter how talented he is, it is impossible for him to acquire knowledge while sleeping.

He had to teach this student a lesson, otherwise the tragedy of hurting Zhongyong might happen to her again.

Some of the other students were worried that Shen Youan wouldn't be able to make a fool of himself, while others obviously wanted to see a joke.

Dare to fall asleep in Teacher Chen's class, thinking that everyone will not be taken seriously by taking the first place in the exam, and I don't believe that Shen Youan is talented enough to learn high mathematics in college.

In the blink of an eye, Shen Youan wrote half of the blackboard, densely packed with derivative formulas.

Chen Zhou looked at it, his eyes gradually became serious.

After writing the last symbol, the chalk in Shen Youan's hand had also died.

After clapping the chalk powder on his hands, Shen Youan turned to look at Chen Zhou.

"Teacher, I'm done."

Chen Zhou pointed to one of the formulas: "If there is f"(X0), and f"(X)=0, then f"(X)≠0.... "

Shen Youan smiled slightly: "Then the following two conclusions can be drawn. If f"(X)<0, then f(X) is its maximum value; if f"(X)>0, then f(X) is its maximum value. minimum value."

Shen Youan pushed the glasses on the bridge of his nose, and said calmly: "For the construction of the concept of derivative, there is a very important question."

Shen Youan picked up a mobile hard disk on the podium and showed it to everyone: "Why do two hard disks with the same size have different capacities?"

Someone replied: "Because the materials are different."

"Given a hard disk, how to maximize its capacity?"

This stumps everyone.

"The capacity of a hard disk depends on the track and sector, the density of the track is related to the track width, and the effective track and width are the decisive factors of the hard disk capacity, so we can establish a limit model to judge the hard disk capacity. As the students said just now, some of your focus is on the volume, and some are on the material. Everyone often starts from the appearance, and if you can jump out of these appearances, you can gain insight into the capacity formation mechanism of the mobile hard disk. , see through the essence through the phenomenon, this is the basis of mathematical modeling."

"For the construction of the concept of derivatives, extreme values ​​are very important, and extreme values ​​themselves are closely related to mathematical modeling."

After Shen Youan finished speaking, he looked at Chen Zhou at the side and nodded slightly: "I'm done."

Hua Luo walked off the podium and walked towards his seat.

The whole class fell silent for an instant.

Even Chen Zhou fell silent for a moment.

The presence or absence of mathematical modeling awareness usually determines the level of problem solving, and also reflects a student's true mathematical literacy.

When the other students were still in the hazy stage, only Shen You'an grasped the key to the affairs and constructed a mathematical model based on the key factors and their connections to complete the analysis and solution of the problem.

This is no longer super-class knowledge, but a dimensionality reduction strike.

Shen Youan, is she really only 14 years old?Such a depth of thought is still in its infancy at the age of 14.

A true genius.

Under the eyes of everyone, Shen Youan returned to his seat, propped his head on one hand, and after a little movement, his body broke out in a cold sweat.

"Oh my god, did Shen Youan even learn advanced mathematics in college? Is he a master of time management?"

Qin Xiange heard the exaggerated exclamation of the tablemate, and tightened his hand holding the pen.

"Maybe her day is 48 hours."

The deskmate muttered: "I think what she said is easier to understand than what Teacher Chen said. If I ask her for advice after class, she shouldn't refuse me, right?"

Chen Zhou knocked on the podium: "All of you focus on me, let's continue talking."

Then Shen Youan went to bed again, and no one dared to gossip anymore.

Before lunch time, everything that happened to Shen Youan in math class spread to all classes in the first year of senior high school at an extremely fast speed.

Everyone sighed unanimously, this is a real boss.

"Hey, Shen You'an, what did you do last night, why do you always sleep today?"

At noon, Gao Yue knocked on Shen Youan's desk.

Shen Youan lay on her stomach without moving.

Gao Yue was so angry that she turned around and left angrily.

Shen Youan fell asleep and woke up, recovering a little.

When she looked up, there was a sandwich and a cup of fruit tea on the desk in front of her.

Shen Youan looked around, it was lunch time, and there were only a few people in twos and threes in the classroom.

Her eyes fell on the thin figure obliquely in front of her.

Recalling the young man's deep and gentle reminder in his ears, he frowned subconsciously.

She has never had any interaction with this Great God Liu, and this one has always been extremely indifferent, how could he meddle in his own business and remind himself of the formula?
Shen Youan pursed her lips, her eyes fell on the sandwich.

She really has no appetite.

And she won't touch things of unknown origin.

At this moment, the young man in front of him turned his head and glanced sideways at her.

Shen Youan was not at all ashamed of being caught, "Thank you for reminding me."

Liu Runxi said lightly: "It's my fault."

Even without a reminder, she can answer beautifully.

She was very smart, wasn't she?

Thinking of this, the corners of the young man's lips curved slightly, like a flash in the pan, the curvature disappeared quickly, and once again turned into an indifference that is thousands of miles away.

"I brought the sandwich and fruit tea. I'm not hungry. You can eat."

Hua Luo turned his head away, leaving Shen Youan with an indifferent back.

Shen Youan frowned, this guy's temper is really weird.

She wasn't hungry, but she was thirsty.

Shen Youan picked up the cup of fruit tea, she was stunned by the warmth of the tentacles.

Inserted the straw and took a sip.

Shen Youan's eyes moved slightly.

It's red candy tea.

She subconsciously raised her eyes to look at the boy's back.

He wouldn't think that he was here.

Thinking of this, Shen Youan coughed suddenly, and coughed violently.

The boy's back remained motionless.

From an angle that Shen Youan didn't see, the boy's hand holding the pen, his finger bones turned white, and blue blood vessels protruded from the back of his hand.

However, he never looked back.

At noon, Jiang Shengyao wandered into the school gate.

Of course the guard didn't dare to stop him, and sent him in with a compensatory smile.

Especially the surly aura of this eldest young master, who would dare to go up and make trouble.

"Jiang Shao, you are never late. To be honest, where did you go for fun last night? Bring your brothers another day."

"Get out of here." Jiang Shengyao yelled angrily, his whole body frantic.

Several people looked at each other and ran away quickly.

Just kidding, no one dares to mess with Young Master Jiang in manic mode.

Jiang Sheng walked to the door of Class A and glanced into the classroom.

In the corner, the girl was still sleeping on her stomach.

Jiang Shengyao snorted coldly.

Sleeping every day, how did you get the first test?

While Jiang Shengyao was hesitating, a girl's gentle voice sounded behind him.

"Ayao, are you here to look for me?"

Jiang Shengyao turned his head and met Qin Xiange's beautiful smiling eyes.

A passing student from Class A peeked at the two with gossipy eyes.

In fact, the two were already a recognized couple at school.

When Jiang Shengyao saw Qin Xiange, Li Yinyin's weeping face rang in his mind, and he almost vomited out the last night's meal.

"Li Yinyin is not worthy to be your friend, so don't worry about her affairs from now on."

After saying these words, Jiang Shengyao was about to leave.

Qin Xiange froze for a moment, and subconsciously grabbed his arm.

"Ayao, what's wrong with you? Yinyin is really pitiful, that's her whole life..."

Jiang Shengyao shook her hand away irritably, and said coldly: "She is pitiful? What a joke, I am the biggest fool in the world if I help her, I advise you to stay away from her in the future, of course she has no face to come to school gone."

"Ayao, what happened, why did you suddenly change so much?"

Qin Xiange didn't understand why Jiang Shengyao had sworn to help her a few days ago, so why did he suddenly change his attitude.

So Shen Youan is all right?

Jiang Shengyao didn't bother to talk to her, and was so angry that he even took it upon Qin Xiange.

"Forget it, it's better that you don't know, remember my words, I'll go first."

Leaving Qin Xiange behind, Jiang Shengyao strode away.

Qin Xiange was at a loss, took out his mobile phone and called Li Yinyin.

Phone off.

For some reason, Qin Xiange suddenly had an ominous premonition in his heart.

"Range."

Accompanied by the girl's arrogant voice, Qin Xiange was suddenly bumped by someone, she staggered, and was about to fall to the side, a pair of arms appeared in time to wrap her around her, saving her from death.

"Be careful." The boy's gentle whisper sounded from above his head.

Qin Xiange stared blankly at the handsome and gentle face in front of him, "Gu...Classmate Gu."

Gao Yue rolled her eyes, and snorted coldly: "It's a rotten drama."

　A drama of grievances and hatreds is about to begin
