Chapter 156 Classmate, change your department! You are wasting your youth in the Mechanical Department
Zhang Yu returned to the dormitory and instantly felt an awkward atmosphere.
Especially Zhao Aiguo, who was lying on the bed minding his own business without saying hello to Zhang Yu, and seemed to be asleep.
Yang Ziqing neatly folded the clothes Zhang Yu lent him and placed them on Zhang Yu's bed.
"Brother Zhang, the clothes have returned to their original owners."
"Okay, I understand. Please tell me if you need anything later."
As for Dalin, he glanced at Zhao Aiguo next door.
"Brother Zhang, you're back."
"Well, I'm back."
The three brothers still had a lot of resentment towards Zhang Yu, especially after Zhang Yu left, when Yan Panpan burst into tears and accused Zhang Yu.
But the real owner was not here, so Yan Panpan vented his emotions on the three Dalin brothers.
For a time, the three brothers were unable to get off the stage and were boycotted by all the girls in the class.
In their opinion, people who can live in the same dormitory as Zhang Yu are not much better in character.
This made the three brothers, who were originally passionate, feel like there was a pouring rain above their heads, extinguishing the fire in their hearts.
Zhang Yu was definitely disappointed when he saw the attitude of the three people, but then he thought about it, what's the big deal?
A person will pass by many passers-by in his life. These three people are just a drop in the ocean. They are not close friends. They have only known each other for two days at most.
Zhang Yu didn’t go to college to make friends, but to strengthen himself. Learning is Zhang Yu’s foundation.
Zhang Yu put his clothes away in the cabinet, went to the bathroom to wash up, sat cross-legged on the bed, and looked at the second unit for a while before turning off the lights and going to sleep.
The next day, early morning.
Zhang Yu got up early, changed his clothes, ran three thousand meters on the playground and exercised a bit.
I returned to the dormitory, took a shower, went to the cafeteria to finish my meal, and then went directly to the classroom.
I went straight to the last row, opened Advanced Generation and continued studying.
Slowly, the students came to the classroom one after another. The first thing they saw was Zhang Yu in the back row, who had already begun to study with Zhen.
Suddenly, many students seemed to understand what Zhang Yu did yesterday, and even some female classmates had a change in their view of Zhang Yu unknowingly.
As time goes by, the whole morning is spent in fulfilling study.
Zhang Yu closed the book and went to the cafeteria. After quickly solving the battle, he quickly walked to the library.
Still the same position, the same rhythm.
When the teacher on duty saw Zhang Yu working hard, a happy smile appeared on his face, and he felt positive about this junior in his heart.
In the morning's study, the math skill bar entered level three. However, as the level gets higher, the understanding of mathematics will increase every time.
Similarly, the progress of the skill bar has also been slowed down a lot by Five Forms.
As your understanding ability improves, the speed of turning pages will naturally become faster and faster.
The teacher on duty noticed Zhang Yu's situation, put down the notebook in his hand, and came behind Zhang Yu.
"Classmate, if you understand this page, just turn it over."
The sudden sound made Zhang Yu tremble.
I quickly turned my head and took a look, and then I calmed down my anxious heart.
"Teacher, if you are scared, you will be scared to death. Thanks to me being young and having a good heart, if you have a heart disease, I can scare you away."
The teacher on duty blushed, but now is not the time to talk about this. The teacher on duty should listen to Zhang Yu explain why he turned the page so fast.
"Where does all this nonsense come from? I'm asking you, do you understand it all and just turn over it?"
"Well, I understand, otherwise I wouldn't be able to translate it like this!"
Why was the teacher on duty so unbelieving? He found paper and pen from the front desk, asked Zhang Yu a question, and handed it to Zhang Yu.
"Now, as long as you can figure it out, I believe you."
Zhang Yu glanced at the teacher, picked up the paper and read it carefully.
"Try to find the positive numbers a and b, so that the equation (X→0)lim1/(x-bsinx)∫t2/√(a t2)dt=1 is established. (∫The upper corner is marked as x, the lower corner is marked as 0)
."
Hey, this question is interesting. Hey, Zhang Yu has actually seen this type of question.
The correct solution to this question automatically comes to mind.
Just pick up the pen and start writing the explanation in the blank space.
"For a typical 0/0 type unfinished formula, just use L'Obitat's rule. The first step is to split the integral. Isn't this difficult? From (X→0)lim(1-bcosx)=0, we can get
b=1, then bring back the original formula, and you can solve a=4. Take a look at the answer to see if my solution is correct."
The teacher on duty was stunned and thought to herself, Wu Cao, are today’s students so awesome?
It didn’t take long before the solution was solved.
I picked up the paper and previewed it quickly.
Nothing wrong with it at all, absolutely right!
"Classmate, how old are you now? Are you a senior?"
The teacher on duty felt that if a senior student could solve it, he would be able to explain it.
"Ah! No! I am a freshman, and today is the third day of enrollment."
Okay! Now it’s become a fright, and the teacher on duty’s eyes almost popped out.
"So you are from the mathematics department?"
"How is it possible? Is it possible for me to reach a higher level in the mathematics department? Teacher, you think too highly of me."
"I am a freshman majoring in the Department of Mechanical Engineering."
The teacher on duty was completely speechless. Fortunately, the teacher didn’t know what Versailles was, otherwise he might have given Zhang Yu a competition.
In the opinion of the teacher on duty, Zhang Yu is completely self-destructive in his career in the Mechanical Department.
"Classmate, do you have any idea of changing your department?"
"Ah? Can I still change my style?"
"Who says it can't be done? I say it can be done. Just wait, I'll go find our dean. You must come to our Department of Mathematics. There will be no future if you follow those who play iron."
The teacher on duty took the paper and quickly left the library.
Zhang Yu is still in a state of confusion. According to the teacher on duty, he is from the mathematics department and he has to force himself to change his department.
How can this be done? I haven’t learned mechanics yet, so how can I change my system?
I quickly picked up my books and ran out of the library, trying to catch up with the teacher.
However, where is the teacher on duty after leaving the library?
Zhang Yu didn’t know where to find the teacher on duty, so he could only take one step at a time.
Just as it happened, it was almost time for class, so Zhang Yu had to go to the classroom first, and walked all the way to the last row to sit down, reading a book and waiting for the teacher.
The teacher on duty came all the way to the dean's office and knocked on the door.
"Please come in."
When I opened the door, I thought that the old man with gray temples was wearing reading glasses and studying mathematics.
This person is the teacher of the first math class of the school year, Mr. Wang.
Dean Wang has been studying mathematics for half his life, and later served as the dean of the Department of Mathematics after the founding of the People's Republic of China.
Dean Wang has two major hobbies, one is to study mathematics topics, and the other is to teach students.
I hope to discover some good ideas in mathematics.
Dean Wang raised his head slightly and saw the teacher on duty coming.
"Xiao He, what's the matter?"
"Dean, I have discovered a genius. Please take a look at this piece of paper first."
Oh?
Teacher Xiao He's words aroused Dean Wang's interest, and he took the paper and took a look.
"Oh! Applying the Law of Peter, the problem-solving ideas are completely correct, and the answer is completely correct."
"Is this done by a senior student in our department?"
The reason why Dean Wang asked this question is because the answer to this question was so perfect that it didn’t look like it was solved by a novice.
"How is it possible? I came to you just because I am not from our mathematics department."
"This child is just a freshman and is a student in the Department of Mechanical Engineering."
"I think he has such a good talent in mathematics. He should not waste time in the Mechanical Department. He should be recruited into the Mathematics Department. Only with your guidance can he better utilize his intelligence."
