I Am the President of the University

Latest website: Mathematics class.

The teacher on the podium may have been paid recently, and he was very energetic when he started the class, and his tone of voice was raised a little bit.

The people in the dormitory of Zheng Tianyu still sat together as usual, perhaps inspired by the recent hard work of Zheng Tianyu and Zhang Lei, and the other four people gradually began to take classes seriously.

The style of study is easy to learn, and it only takes a few days; to learn well, it may take a few weeks.

"Woo~" Shi Ze couldn't help but yawned. The math class was too difficult for him.

"Aze, if you want to sleep, go to sleep? I want to sleep because I keep yawning!" Roommate Chen Chu looked at Shi Ze with a grimace. This guy has been yawning without going to bed for half of the class!

Shi Ze looked sleepy and insisted: "How can such a sacred place in the classroom be used for sleeping!"

Zhang Lei looked at Shi Ze with a look of "rotten wood can't be carved", and said jokingly: "I believe it, you guess how long Aze can last? I guess 3 minutes!"

"Five minutes! Aze is a five-pointer after all!"

"2 minutes, no more."

"1 minute!"

Shi Ze lay on the table as soon as a few friends spoke.

Tao Yalun who guessed for five minutes exclaimed:

"I'm careless, I actually believed Aze's morals!"

Tao Yalun asked in a low voice, "Aze, didn't you just say that the classroom is not for sleeping?"

Shi Ze grumbled and replied: "I am not sleeping, I am here to submit learning efficiency, strategic supplementary supplies, and call me when get out of class is over..."

Zhang Lei and others have been immune to Shi Ze’s "righteous words" every time...

Jumping over Shi Ze, Tao Yalun showed concern on his face and asked: "Old Zheng, how is your model team running together?"

After all, the two of them recently went to classroom 606 of the teaching building to receive training in their spare time, except for classes. If Tao Yalun and others knew what Zheng Tianyu and Zhang Lei were doing, they would all wonder if they were doing it. What illegal things have gone.

But... even knowing that he was busy in the digital simulation contest, still stunned the four friends in the dormitory.

After taking a second private university, 80% of people accepted their fate.

Maybe you will listen carefully during class, but don't think about self-study after class.

Except for the month approaching the final exam, when does the library need to grab a spot?

Just kidding, the library is a place for couples to talk and date...

"The running-in is not bad, the classmate in charge of modeling is very good." Zheng Tianyu replied seriously.

Lu Zhou's strength is on the bright side, coupled with his programming level, if you ignore Zhang Lei, who is in charge of the thesis, then Zheng Tianyu is full of confidence!

It is a pity that the two gods bring a pit.

Let's start at fifty-five!

Zhang Lei interjected dissatisfiedly and said: "What does it mean to be responsible for modeling, and my paper is not bad, okay?"

"just you?"

Zheng Tianyu said that he almost laughed and screamed, "A few days ago, you didn't even know what the review of the paper was. Did you tell me the writing was not bad?"

"Well, it's fortunate that you know HowNet."

When Zhang Lei heard this, he only felt that he was underestimated, and his voice was uncontrollable and said: "Old thief Zheng, today I am going to a showdown with you... a showdown!"

"Who is this classmate going to fight against? Come, come up and compare with this topic first."

Zhang Lei didn't wait for Zheng Tianyu's reply, but instead waited for the teacher's voice.

The emotion was too loud just now, so the teacher heard it all.

"Ha ha ha ha!"

At that moment, the classroom was still quiet and laughed.

"Come, come, come to the podium to solve the problem, otherwise the teacher must remember your name." The math teacher looked at Zhang Lei with a slight smile.

And all the classmates also watched themselves.

Zhang Lei, who was at the center of his eyes, was embarrassed.

If there is a crack in the ground, he will definitely get in!

"Lao Zhang, hurry up! The teacher is looking at you, otherwise you will be careful to put on your shoes!" Zheng Tianyu roared excitedly from the side.

"That is, come on stage and show off your strength."

"If you can't solve the problem, don't say that our dormitory went out, otherwise it will be ashamed!"

"Zhang Lei, there are only a few girls in the class, but they are all staring at you, it's time to show off their prowess."

What do friends do? It's for selling!

Several roommates were fanning the flames, especially the last one, which directly stimulated Zhang Lei.

As a computer major, there are still girls in the class, much better than mechanics and civil engineering, at least 8:2.

The only female classmates in the class, as long as they are slightly better-looking, they are all treasures!

The single Zhang Lei stood up abruptly and walked to the podium, whispering at the corner of his mouth as he walked.

"Look down! It's time to show real technology!"

Just as soon as he walked up, in front of Teacher Laidao, Zhang Lei hung an embarrassed face, scratched his head, and said, "Teacher, which question?"

The math teacher pointed to the right side of the blackboard and turned on the theater mode, "The question on the right, since you can be distracted to chat in class, it must be all right?"

"It's okay." Zhang Lei found the problem and walked over, only poking his lips secretly when turning his back to the teacher.

Immediately picked up the chalk on the blackboard and looked at the topic carefully.

[Why when x→0, 1+x-under the radical sign 1-x and x are equivalent to infinitesimal quantities? 】

"It doesn't seem to be difficult."

Zhang Lei recalled the training these few days in his mind, because it was a training camp, all three of them had to participate.

Even if he is a writer who is only responsible for thesis writing and defense, he has to learn mathematical modeling and programming.

And this question... just not a problem for him.

Focusing on the subject, the brain turns on at high speed.

The chalk moves, and as the dust flies in the air, the formula is gradually perfected...

[Lim(x->0)[√(1+x)-√(1-x)]/x is rationalized

=lim(x->0)[(1+x)-(1-x)]/{x[√(1+x)+√(1-x)]}

=lim(x->0)2/[√(1+x)+√(1-x)]

=2/[1+1]

=1

So √(1+x)-√(1-x) and x are equivalent to infinitesimal]

"Fuck!"

Zhang Lei clapped his hands and turned to the math teacher to show a smile that he thought was very nice, "Teacher, I'm done writing."

Throwing the chalk on the hand, following a perfect parabola, the chalk skimmed over the place where the chalk was placed on the blackboard and fell to the ground.

The math teacher raised his eyebrows and asked casually: "It's not difficult, isn't it?"

As soon as Zhang Lei stepped off the stage, he subconsciously replied without thinking: "Fortunately, it is not difficult."

Then……

A word from the math teacher almost made him somersault.

"I just heard your roommate call you Zhang Lei?"

"Um... you can solve problems without much listening to mathematics. It's really amazing. I will call you up to answer the questions in every class in the future, so that my classmates will know you more."

Zhang Lei has ten thousand grass and mud horses running over his head~www.readwn.com~ which **** called my name! !

When I returned to my seat again, I felt the wretched laughter from several roommates and classmates before and after.

Zhang Lei looked up to the sky at an angle of 45°.

"Zhang Lei, why are the corners of your eyes wet!"

Zhang Lei shook his head and denied:

"When I just solved the problem, the chalk shavings got into my eyes! It's okay, I just slow down! Leave me alone!"

ps: Ask for a recommendation ticket, ask for a monthly pass!

Oh, if it weren’t for the last chapter for so long, I would have coded all three chapters.

The takeaway hasn't arrived yet, so hungry. . . I knew I wouldn't order takeaway and I ate it on the road. It's too unlucky today. . .
