I Am the President of the University

Latest website: In math class.

The teacher on the podium was particularly energetic when giving lectures, perhaps because he had received his salary recently, and his tone of voice rose a bit.

Zheng Tianyu and others in the dormitory were still sitting together as usual. Perhaps inspired by Zheng Tianyu and Zhang Lei's recent hard study, the other four people gradually began to take class seriously.

It is easy to learn a bad style of study and only takes a few days; it is difficult to learn a good style and it may take several weeks.

"Ouch~" Shi Ze couldn't help yawning. The advanced mathematics class was too difficult for him.

"Aze, why don't you go to bed when you feel sleepy? You keep yawning and making me want to sleep too!" Roommate Chen Chu looked at Shi Ze with a look of resentment. This guy stayed up for half the class and kept yawning!

Shi Ze looked sleepy and said, "How can such a sacred place as the classroom be used for sleeping?"

Zhang Lei looked at Shi Ze with a look that said, "Rotten wood cannot be carved." He said jokingly: "I believe it. How long do you think A Ze can last? I guess 3 minutes!"

"Five minutes! After all, Aze is a five-point man!"

"Two minutes, no more."

"1 minute!"

As soon as the words came out of the mouth of the friends, Shi Ze lay on the table.

Tao Yalun, who guessed for five minutes, exclaimed:

"I was careless, I actually believed in Aze's integrity!"

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

Shi Ze muttered and replied: "I'm not sleeping. I'm here to improve my study efficiency and strategically replenish supplies. Call me after class later..."

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

Skipping Shi Ze, Tao Yalun showed concern on his face and asked: "Old Zheng, how is your digital simulation team getting along?"

After all, apart from attending classes recently, the two of them have been busy receiving training in Class 606 of the teaching building in their spare time. They leave early and come back late every day. If Tao Yalun and others had not known what Zheng Tianyu and Zhang Lei were busy with, they would have doubted whether they were doing it. What illegal thing happened.

However...even if they knew they were busy working on the digital analog competition, the four friends in the dormitory were shocked.

80% of people would accept their fate if they were admitted to a second-tier private university.

Maybe you will listen carefully during class, but don’t think about studying it on your own after class.

Besides the month leading up to final exams, when does the library need to compete for space?

Just kidding, the library is where couples go to fall in love and date...

"The running-in is pretty good. The classmate in charge of modeling is very good." Zheng Tianyu replied seriously.

Lu Zhou's strength is obvious, coupled with his programming skills, if he ignores Zhang Lei, who is in charge of the paper, it will make Zheng Tianyu full of confidence!

It's a pity that two gods lead to a trap.

Let’s open it 50-50!

Zhang Lei interjected dissatisfiedly and said: "What does it mean to be good at modeling? My paper writing is not bad, right?"

"just you?"

Zheng Tianyu almost laughed like a pig when he said this, "A few days ago, you didn't even know what a paper review was, and you told me that your writing was not bad?"

"Well, it's a good thing you know CNKI."

When Zhang Lei heard this, he felt that he was being despised and said without controlling his voice: "Old thief Zheng, today I will have a showdown with you... a showdown!"

"Who does this classmate want to compete with? Come on, come up and compete with this question first."

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

Because the emotion was too loud just now, the teacher heard it.

"Ha ha ha ha!"

The classroom that was originally quiet suddenly burst into laughter.

"Come on, come to the podium and solve the problems, otherwise the teacher will have to remember your name." The math teacher looked at Zhang Lei with a smile.

And all the classmates in the room were also looking at me.

But Zhang Lei, whose eyes were focused, was embarrassed.

If there was a crack in the ground, he would definitely get in!

"Lao Zhang, come up quickly! The teacher is watching you, otherwise be careful to wear small shoes for you!" Zheng Tianyu shouted excitedly from the side.

"That's right, come on stage and show your strength."

"If you can't solve the problem, don't say you went out of our dormitory, otherwise you'll be embarrassed!"

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

What are friends for? It’s just for sale!

Several roommates were fanning the flames, especially the last one, who directly irritated Zhang Lei.

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

There are only a few female classmates in the class, and any one who is a little bit good-looking is a treasure!

Zhang Lei, who was single, stood up suddenly and walked to the podium, muttering in a low voice as he walked.

"Look at it! It's time to show off your true skills!"

Just as he walked up, in front of the teacher, Zhang Lei looked embarrassed, 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 distract yourself from chatting in class, you must know it well, right?"

"It's not bad." Zhang Lei found the topic and walked over, only pouting secretly when his back was turned to the teacher.

He immediately picked up the chalk on the blackboard and looked at the question carefully.

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

"It doesn't seem to be difficult."

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

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

And this question... happened to not be a problem for him.

Keeping your eyes on the topic, your brain starts running at high speed.

The chalk moved, and as dust flew in the air, the formula was slowly perfected...

[lim(x-\u003e0)[√(1+x)-√(1-x)]/x molecule rationalization

=lim(x-\u003e0)[(1+x)-(1-x)]/{x[√(1+x)+√(1-x)]}

=lim(x-\u003e0)2/[√(1+x)+√(1-x)]

=2/[1+1]

=1

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

"Bah bang bang!"

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

Throwing away the chalk on the handle, following a perfect parabola, the chalk flew past the place where the chalk was placed on the blackboard and fell to the ground.

The math teacher raised his eyebrows and asked casually: "Isn't it difficult?"

Zhang Lei just stepped off the podium and subconsciously replied without thinking: "Fortunately, it's really not difficult."

Then……

The math teacher's words made him almost fall over.

"I thought I heard your roommate calling you Zhang Lei just now?"

"Well... you can solve math problems without even attending a lot of lectures. It's really impressive. I will ask you to answer questions in every class from now on so that the classmates can get to know you better."

Zhang Lei had 10,000 grass and mud horses running overhead.

What bastard called my name! !

When I returned to my seat, I felt the lewd laughter coming from several roommates and classmates before and after me.

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 was just solving a problem, chalk shards got into my eyes! It's okay, I'll just slow down and it'll be fine! Don't pay attention to me!"

ps: Please give me recommendations and monthly votes!

Woohoo, if I hadn’t worked on the last chapter for so long, I would have coded out all three chapters.

The takeaway hasn’t arrived yet, so I’m so hungry. . . If I had known better, I would have stopped ordering takeout and ate it on the road. Today was such an unlucky day. . .
