Chapter 4: I've brushed the book when others answered the question

At 6:00 in the morning, I felt a slight vibration of the bedboard. Liu Rui narrowed his eyes before he woke up, looking around for the source of the earthquake. He saw the Lu Zhou sleeping on his other side holding the ladder and climbed down, he hummed and asked: "Elbow, get up so early?"
Afraid of making noise to the other two sleeping roommates, Lu Zhou whispered back.
"Ok."
瑞 Liu Rui refused to ask.
"Going to work part-time?"
Lu Zhou hesitated, and shook his head, "No more, rest these days."
"Where did you go so early?"
"Library."
瑞 Liu Rui is not sleepy in an instant.
After brushing his teeth in the sink, Lu Zhou turned to a toilet by the way. After coming out of the toilet, he saw Liu Rui crawling under the bed, and asked strangely, "Are you asleep?"
"Review." Liu Rui picked up the brushing cylinder, came to this trot and went to the balcony washbasin.
I looked at my roommate who was close to the enemy. Lu Zhou was crying and laughing. He shook his head and said nothing. After putting on his shoes and carrying a bag, he went out.
Jinling in June is like a stove, except at five or six in the morning.
The fragrance of Chaolu is mixed in the air, and the breeze that occasionally blows on the cheeks is not hot and refreshing. At six o'clock, the campus is like a quiet girl who walks from the mid-morning section, as if it were two worlds here in the evening.
I went to the cafeteria and bought two buns and a cup of soy milk. After the morning, Lu Zhou walked slowly to the library.
Jinling University is indeed a well-known institution of higher learning throughout the country. At this point, the library staff have not yet come to work, and many people are already standing in the morning in the open space.
I also took out the fourth-level word book and memorized it for a while. Although it was not as good as in the library, the effect was still acceptable under the influence of the surrounding learning atmosphere. Lu Zhou waited until 7:30 at the entrance of the library to see that the library staff was late and finally opened the door.
With the library door open, the postgraduate army poured in like tide, and soon the open space at the library door was cleared.
As the crowd rushed in, Lu Zhou didn't rush to start exploring the ocean of books. Instead, he went to the bookshelf and picked up this "Higher Algebra Tu Boyun Edition", then went to the corner of the library to find a quiet place to sit.
Lu Zhou estimated that in an immersive reading state, it takes about one hour to two hours to fully understand the knowledge points of a unit, which includes the knowledge point memory, brain calculations, and problem analysis.
Judging from the current number of pages remaining, this "New Lecture on Mathematical Analysis" can still last up to one morning. In the afternoon, he intends to take this opportunity to supplement his knowledge of advanced algebra.
He took a deep breath, and Lu Zhou turned the New Lecture on Mathematical Analysis to the position where the bookmark was jammed yesterday, and continued to focus on the book.
Soon, he entered the state of yesterday again, and the whole person forgot the foreign object, as if the only book in the world ...
The time passed by one minute and one second, and at 11.30 noon, Lu Zhou breathed a sigh of relief and put down the book in his hand.
This "New Lecture on Mathematical Analysis" has been completely read, and its value coefficient has also dropped to 5.
This also confirms Lu Zhou's guess. The system's evaluation of the book's value coefficient is not based on the academic world of this world, but on its own level of knowledge.
As for why it is 5 instead of 0, it may be that the book has hidden areas that he has not completely eaten. You may have to read it again if you want to eat it completely.
However, Lu Zhou obviously will not do this. In order to tap the 5 value coefficient and waste valuable deep reading time, it is a loss-making transaction.
It was just time for dinner, Lu Zhou put down his books and walked outside the library.
As he passed the main entrance of the library, he squinted at the holographic image at the door, and saw that the remaining time of the on-hook task had become 18 hours.
Lu Zhou suddenly felt that the task could not be completed so quickly. In these 6 hours, he felt that he had learned more than last year.
I thought of the "Advanced Algebra" that had not been opened on the table, and Lu Zhou walking on the way to the cafeteria touched his chin.
There is still a C language to be tested at the end of the period. Should you stop looking for a C language book?
Also English.
I just do n’t know if English books have a value coefficient. Anyway, those English newspapers placed in front of the library are not available. This black technology system seems to have a strange prejudice against liberal arts majors.
刷 Brushed the bowl set with a rice card, and Lu Zhou hurried back to the library after eating. First went to the counter to return the books I had read, and then went to the bookshelf. I took the fifth version of C Detailed Explanation from the bookshelf and clipped it under my arm.
The lunch break is over, and there are more people in the library.
With no hesitation in mind, the book "Advanced Algebra", Lu Zhou was about to enter the next point of knowledge, and suddenly felt something was poked in his arm. Looking sideways, I saw a pretty girl with round glasses and a single ponytail. She was holding a pen in her hand and looked at herself embarrassedly.
"Classmate, sorry to disturb you ... can I ask you a question?"
Lu Zhou nodded generously and said, "No problem, just ask."
Although he was interrupted by brushing, he was not angry at all.
I want to ask why.
I have to say that human beings are aesthetic animals. In the interaction between people, the value of face is really important.
Why didn't this girl look for others, but she just found me?
It's not because we look handsomer than others!
Lu Zhou likes to talk to such visionary and honest people.
If you don't plan anything, you just want it!
"Thank you." Whispered thank you, the girl gently lifted the chair, sat next to Lu Zhou, and handed over the pen and draft paper thoughtfully.
Lu Zhou was also welcome. After receiving the pen and paper, he narrowed his eyes.
让 "Let me see ... seek the limits, right?"
Try to find the positive numbers a and b so that the equation (X → 0) lim1 / (x-bsinx) ∫t2 / √ (a + t2) dt = 1 holds. (∫ The upper corner is labeled x and the lower corner is labeled 0)
I don't seem to have done this question, but when I read a book just now, I seem to have seen similar questions.
I just watched the high generation just now, and tested the strength of the system a little bit.
Habitually turned around, Lu Zhou thought for a while, and before a minute, he opened his mouth and said, "It's solved."
"Here, this solved it?" Chen Yushan looked at Lu Zhou in disbelief, and said to her that you hadn't done anything yet.
瞟 Lu Zhou gave the girl a glance and said that the milk volume was inversely proportional to IQ.
But to be honest, he was surprised by his own speed of solving the problem. Although he had never encountered such a problem before, he would never solve it so easily, so smoothly, he did n’t even have draft paper. Yes, the problem-solving process is clear.
Nor was hesitant, Lu Zhou said nothing about holding the pen, and wrote the understanding process on the draft paper in an open manner, and explained it as he wrote: "Typical 0/0 type infinitive formula, directly using Lopita's law Well, the first step is to disassemble the integral first, isn't it difficult? From (X → 0) lim (1-) = 0, we can get b = 1, and then bring it back to the original formula, which can solve a = 4, Look at the answer, see if I understand it. "
Chen Yushan stared blankly at the draft, only feeling that this guy was solving the question faster than he was listening.
Especially when the last two answers were written, her thinking was still in the step of solving the integral.
With a sense of doubt, she opened the answer, her eyes suddenly widened ~ EbookFREE.me ~ This is really the answer! ?
I noticed the expression on the girl's face, and a bit of a disappointed Lu Zhou smiled and turned to the pen and said, "It is very simple to apply the Lopita rule, and the calculation itself is not difficult. Speaking of which you are a freshman? What specialty?"
玉 Chen Yushan blushed and whispered, "I took the postgraduate ..."
As soon as she finished speaking, her face turned redder.
I am not shy, I am so angry!
I'm so angry!
I do n’t mean to solve the math problem, what is it? I haven't touched this knowledge of mathematics for so many years, what happened to the teacher? There is no such thing as a single dog! Deserve to be alone in the library!
I thought of this, and Chen Yushan was a little deflated.
As for her own library, she was ignored by her.
"Uh." Lu Zhou's expression was a little awkward. He had thought that he was in the same grade as himself.
I just wanted to say sorry, and coughed heavily from the row in front of the two.
I realized that the sound of the two speeches disturbed the others. Chen Yushan blushed, stuck her tongue out, and returned to her place holding the exercise book and draft paper.
I have no chance to apologize, let alone ask the name and WeChat ...
I sat there tangled for a while, then he shook his head and continued to pick up the unfinished "Advanced Algebra".
How can sister-in-law learn?
Interpersonal relationships?
Sorry, Zhen Xueba doesn't need that stuff.
Raising mathematics to LV1 is equivalent to owning the entire world!
After a short while, Lu Zhou entered the state and completely left the matter behind, just as an episode of brushing books in the library.
