"Shen You'an, you can answer this question."

The girl lay on the table, as if in a coma.

On the podium, Chen Zhou's face was pale, and he smashed it towards Shen You'an in the corner with chalk in his hand.

The whole class turned their heads at the same time.

There is no shortage of gloating eyes.

Unexpectedly, Shen Youan was also caught by Teacher Chen when she deserted in class, and she was miserable now.

Chen Zhou, graduated from the Department of Mathematics of Qingdao University, studied under the famous mathematician Academician Jiang Han, chairman of the National Mathematical Association, and has a pivotal position in the domestic mathematics community.

One of his lessons is hard to find.

Someone dared to sleep in his class, and the fastidious Chen Zhou could imagine how angry he was.

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

"Student Shen, wake up."

The chalk head hit Shen You'an's 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 face was too pale and bloodless.

Yoo Yunxi, who turned his head, saw this scene, his eyes were slightly dark behind the lenses, and he turned back quietly.

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

Chen Zhou slapped the table and roared.

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

Gu Bichen looked at her worriedly: "Classmate Shen......." ”

Passing by Yoo Yun-hee's desk, Yoo Yun-hee lowered his voice and said a word.

Yan Lu glanced at her table mate in some surprise.

The two sat at the same table for two weeks, but this one didn't say a word to her, and it looked like he was about to become an immortal.

But he actually took the initiative to remind Shen You'an.

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

After a moment of contemplation, he picked up a piece of chalk on the podium and began to answer the questions.

Chen Zhou stood aside with his arms crossed, looking at him coldly.

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

The students in the class have basically pre-studied the content of the first volume of the first year of high school during the summer vacation, and even the gold medal tutor invited is already talking about the content of the second year of high school.

And his way of teaching is more casual, where he wants to speak, regardless of whether the students can understand it or not.

The so-called genius class must have the characteristics of genius, what is the meaning of step-by-step?

The abstract nature of mathematics requires students to exert sufficient imagination space and construct rigorous logical thinking in that vast space, which is a process that requires long-term training.

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

However, if a class is deserted, it is like dominoes, a vicious circle.

He would never allow this to happen to the students he taught, disrespecting him and disrespecting mathematics.

The derivative formula taught in this class has obviously exceeded the outline, involving college advanced mathematics calculus, and the upcoming mathematics joint entrance examination will usually involve this knowledge, so he will talk more.

Shen You'an is indeed a genius, but no matter how talented he is, it is impossible to learn the knowledge when he is sleeping.

He had to teach this student a lesson, otherwise the tragedy that hurt Zhongyong was likely to be repeated in her.

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

dared to sleep in Teacher Chen's class, thinking that he would not take everyone seriously after taking the first exam, and he didn't believe that Shen You'an was 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, and his eyes gradually became serious.

Writing down the last symbol, the chalk in Shen Youan's hand has also died.

Patting the end of the chalk on his hand, Shen Youan turned his head to look at Chen Zhou.

"Teacher, I'm done."

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

Shen Youan smiled slightly: "Then the following two conclusions can be drawn, if f"(X)0, then f(X) is its minimum." ”

Shen Youan pushed the glasses on the bridge of his nose and said very calmly: "There is a very important question for the construction of the concept of derivatives. ”

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

Someone replied, "Because the material is different." ”

"If you are given a hard drive, how do you maximize its capacity?"

This stumped everyone.

"The capacity of the hard disk depends on the track and the sector, the density of the track is related to the width of the track, and the effective track and width is the decisive factor of the capacity of a hard disk, so we can establish a limit model to judge the maximum value of the hard disk capacity, as the students just said, your focus is on the volume, some on the material, we often start 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, and see through the essence through the phenomenon, This is the basis of mathematical modeling. ”

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

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

He stepped off the podium and walked towards his seat.

The class fell silent for a moment.

Even Chen Zhou was silent for a while.

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

While the other students were still in the hazy stage, only Shen You'an grasped the key to the matter and used the key factors and their connections to build a mathematical model to complete the analysis and solution of the problem.

This is no longer supernatural knowledge, but a dimensionality reduction strike.

Shen You'an, is she really only fourteen years old? With such a depth of thought, he is still in the embryonic stage at the age of fourteen.

What a real genius.

Under the gaze of everyone, Shen Youan returned to his seat, supported his head with one hand, and after a little movement, he was sweating profusely.

"Oh my God, did Shen Youan even learn the high math of college in advance? A master of time management? ”

Qin Xiange listened to the exaggerated exclamations of his fellow tablemates, and his hand holding the pen tightened.

"Maybe she's forty-eight hours a day."

The tablemate muttered: "I think what she said is more simple and understandable than what Teacher Chen said, if I ask her for advice after class, she probably won't refuse me, right?" ”

Chen Zhou knocked on the podium: "Give me all your attention, let's continue to talk." ”

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

Before lunchtime, everything that happened to Shen You'an in math class spread throughout the first year of high school classes at a very fast speed.

Everyone unanimously sighed that this is a real boss.

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

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

Shen Youan lay on his stomach and didn't move.

Gao Yucao was extremely angry, turned around and walked away in a huff.

Shen slept peacefully again, and his spirit recovered a little.

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

Shen You'an looked around, it was lunchtime, and there were only a few people in the classroom.

Her gaze fell on the thin back in front of her.

Remembering the young man's low and gentle reminder, he subconsciously frowned.

She has never had a point in contact with this Liu Dashen, and this one has always been extremely indifferent, how can he meddle in reminding himself of the formula?

Shen Youan pursed his lips and his gaze fell on the sandwich.

She really has no appetite.

And she won't touch anything from an unknown source.

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

Shen Youan was not embarrassed at all by being caught, "Thank you for reminding me." ”

Liu Yunxi said lightly: "It's me who has done more." ”

Even without reminders, she was able to answer beautifully.

She's smart, isn't she?

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

"I brought the sandwich and fruit tea, I'm not hungry, you can eat it."

The words turned his head away, leaving Shen You'an with an indifferent back.

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

She wasn't hungry, but she did get a little thirsty.

Shen You'an picked up the cup of fruit tea, and the warmth of the tentacles made her stunned.

Insert the straw and take a sip.

Shen You'an's eyes moved slightly.

It is red candy tea.

She subconsciously raised her eyes and looked at the young man's back.

He wouldn't think he was coming.

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

The boy's back remained still.

Shen You'an didn't see the angle, the young man's hand holding the pen, the finger bones were white, and the cyan blood vessels on the back of the hand were bulging.

However, he never looked back.

~

It was almost noon, and Jiang Shengyao shook into the school gate.

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

Especially the eldest young master's obedient aura, who dares to go up and touch the moldy head.

"Jiang Shao, you are usually never late, to be honest, where did you go last night? Bring your brothers another day. ”

"Get out of here." Jiang Shengyao shouted angrily, full of mania.

Several people looked at each other and hurriedly ran away.

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

Jiang Shengyao shook 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?

Just as Jiang Shengyao was hesitating, the girl's gentle voice sounded behind him.

"Yao, are you here to find me?"

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

The students passing by in Class A peeked at the two of them with gossipy eyes.

In fact, these two are already a recognized pair at school.

Jiang Shengyao saw Qin Xiange's tearful face in his mind, and he was about to vomit out of his overnight meal.

"Li Yinyin is not worthy of being your friend, you don't have to worry about her affairs in the future."

Leaving this sentence, Jiang Shengyao was about to leave.

Qin Xiange was stunned and subconsciously grabbed his arm.

"A-Yao, what's wrong with you? Yin Yin is really pitiful, that is the ...... of her life. ”

Jiang Shengyao shook off her hand irritably, and said coldly: "She is pitiful? It's a joke, I'm the biggest fool in the world when I help her, I advise you to stay away from her in the future, of course, she doesn't have the face to come to school. ”

"A-Yao, what happened, why did you suddenly change so much?"

Qin Xiange was a little incomprehensible, obviously Jiang Shengyao had promised to help her a few days ago, why did he suddenly change his attitude.

Wouldn't Shen You'an be okay like this?

Jiang Shengyao didn't bother to say more to her, his stomach was full of anger, and he even became angry with Qin Xiange.

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

Putting down Qin Xiange, Jiang Shengyao strode away.

Qin Xiange was confused, took out his mobile phone and called Li Yinyin.

The phone is turned off.

I don't know why, Qin Xiange suddenly had an ominous premonition in his heart.

"Let's make it."

Accompanied by the girl's arrogant voice, Qin Xiange was suddenly bumped, her whole body staggered, and she was about to fall to the side, but a pair of arms appeared in time to encircle her, allowing her to survive.

"Be careful." A young man's gentle whisper sounded overhead.

Qin Xiange stared at the handsome and gentle face in front of him in a daze, "Gu ...... Gu classmates. ”

Gao Yucao rolled her eyes and snorted coldly: "The vulgar drama at home." ”

A big drama of grievances and hatred is about to begin
