At 6 o'clock in the morning, feeling a slight vibration of the bed board, Liu Rui squinted his eyes that had not woken up yet, looked around for the source of the epicenter, and happened to see Lu Zhou, who was sleeping on the other end of him, holding a ladder and climbing down, so he hummed and asked: "Elbow, get up so early?" ”

Afraid of noisy the other two roommates who were still sleeping, Lu Zhou replied in a low voice.

"Hmm."

Liu Rui asked unrelentingly.

"Still going to work part-time?"

Lu Zhou hesitated, shook his head and said, "No, rest for the past few days." ”

"And where are you going so early?"

"Library."

Liu Rui was not sleepy in an instant.

After going to the washbasin to brush his teeth, Lu Zhou turned around and went to the toilet, and after coming out of the bathroom, he happened to see Liu Rui also crawling under the bed, so he asked strangely: "You don't sleep?" ”

"Review." Liu Rui picked up the toothbrush jar and trotted to the balcony washbasin.

Looking at his roommate, who was like a great enemy, Lu Zhou couldn't cry or laugh in his heart, shook his head and didn't say anything, put on his shoes and bag, and went out.

Jinling in June is like a furnace, with the exception of five or six o'clock in the morning.

The air is mixed with the fragrance of morning dew, and the breeze that occasionally blows on the cheeks is not hot, but all refreshing. The campus at six o'clock is like a quiet girl, coming from the middle of the morning and dusk, and it seems to be two worlds here in the evening.

I went to the cafeteria to buy two steamed buns and a cup of soy milk, and after breakfast, Lu Zhou walked slowly to the library.

Jinling University is a well-known institution of higher learning throughout the country, and the staff of the library at this point have not yet come to work, and many people are already standing in the open space outside to read in the morning.

I also took out the fourth-level vocabulary book and memorized it for a while, although it was not as good as being in the library, but under the influence of the surrounding learning atmosphere, the effect was okay. Lu Zhou waited at the door of the library until half past seven, only to see that the library staff had finally opened the door after a long time.

As the door of the library opened, the army of graduate students poured in, and soon the open space at the entrance of the library was cleared.

As the crowd poured in, Lu Zhou did not rush to start swimming in the sea of books, but went to the bookshelf and picked out a copy of "Advanced Algebra Tu Boyun Edition", and then went to the corner of the library to find a secluded place to sit down.

Lu Zhou estimated that in the state of immersive reading, it takes about an hour to two hours to understand the knowledge points of a unit, which includes various links such as knowledge point memory, brain calculus, and question type analysis.

Judging from the number of pages left so far, this book "New Lectures on Mathematical Analysis" in hand can last for a morning at most. In the afternoon, he plans to take this opportunity to supplement his knowledge of advanced algebra.

Taking a deep breath, Lu Zhou flipped "New Lectures on Mathematical Analysis" to the position where he stuffed the bookmark yesterday, and continued to focus on the book.

Soon, he entered the same state as yesterday again, and the whole person forgot about external objects, as if he were the only me in the world......

Time passed minute by minute, and at half past eleven o'clock in the afternoon, Lu Zhou let out a sigh of relief and put down the book in his hand.

This "New Lecture on Mathematical Analysis" can be regarded as a complete reading, and its value coefficient has been reduced to 5.

This also just confirms Lu Zhou's guess that the system's evaluation of the value coefficient of books is not based on the academic world of the world, but on his own knowledge level.

As for why it's 5 instead of 0, it may be that there are still things in this book that he hasn't fully understood, and he may have to read it again if he wants to fully understand it.

However, Lu Zhou obviously won't do this, wasting valuable in-depth reading time in order to dig out those 5 value coefficients, no matter how you look at it, it's a loss-making deal.

It was also time to eat, Lu Zhou put down the books in his hand and walked outside the library.

As he passed by the main entrance of the library, he glanced at the hologram at the door, and saw that the remaining time for the AFK task had become 18 hours.

Lu Zhou suddenly felt that it was okay not to complete the task so quickly, and in just these six hours, he felt that he had learned more than he had learned in the whole of last year.

Thinking of the book of "Advanced Algebra" that had not yet been opened on the table, Lu Zhou, who was walking on the way to the cafeteria, touched his chin.

At the end of the term, there is still a C language to be examined, do you want to look for a C language book?

And English.

I just don't know if English books have a value coefficient.,Anyway, those English newspapers at the door of the library don't have it.,This black technology system,There seems to be a strange prejudice against liberal arts majors.,It's not very good.。

Swiped the bowl set meal with the meal card, and after eating, Lu Zhou hurried back to the library. I went to the counter first to return the books I had read, then went to the bookshelf, took a copy of "C Language Explained in Detail Fifth Edition" from the shelf, sandwiched it under my arm, and returned to my seat.

After the lunch break, there were more people in the library again.

Nibbling on the book "Advanced Algebra" without distraction, Lu Zhou was about to enter the next knowledge point, when he suddenly felt something poke his arm. When I turned my face to the side, I saw a delicate girl wearing round-framed glasses and a single ponytail, holding a pen in her hand, looking at herself embarrassedly.

"Classmate, I'm 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 his book, he was not angry at all.

To ask why.

I have to say that human beings are aesthetic animals, and in the interaction between people, appearance is really important.

Why didn't this girl find someone else, but found me?

It's not because we're more handsome than others!

Lu Zhou likes to talk to this kind of discerning and honest person.

Don't want anything, just be happy!

"Thank you." whispered a word of thanks, and the girl gently lifted a chair, sat down next to Lu Zhou, and thoughtfully handed over a pen and scratch paper.

Lu Zhou was not polite, and after taking the pen and paper, he glanced at the topic.

"Let me see...... Limit it, 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. (∫ is marked with x in the upper corner and 0 in the lower corner)

I don't think I've ever done this question, but when I read the book just now, I seem to have seen a similar type of question.

It just happened that I was looking at the high generation, so I tested the strength of the system a little.

Habitually turning the pen, Lu Zhou thought for a while, and before a minute passed, he said, "It's solved." ”

"This, this is solved?" Chen Yushan looked at Lu Zhou in disbelief, and said in her heart You haven't even started writing yet, how can you solve it.

Lu Zhou glanced at the girl, and said in his heart that this amount of milk is really inversely proportional to IQ.

But to be honest, he himself was also taken aback by his own problem-solving speed, although he encountered this kind of problem in the past, although it was not impossible to solve, it would never be so easy to solve, so smooth, even scratch paper was useless, and the problem-solving process was clear.

is not hypocritical, Lu Zhou grabbed the pen without saying a word, and wrote down the process of solving the problem on the scratch paper with enthusiasm, and explained it while writing: "The typical 0/0 type infinitive, directly use the law of Lopida, the first step is to disassemble the integral, this is not difficult, right?" From (X→0)lim(1-bcosx)=0, you can get b=1, and then bring back the original formula, you can solve a=4, you look at the answer, see if I solved it correctly. ”

Chen Yushan stared at the draft book in a daze, only feeling that this guy's speed of solving the problem was faster than the speed of his own lectures.

Especially when the last two answers were written, her mind was still stuck in the step of solving the integral.

With a skeptical feeling, she opened the answer, and her eyes widened.

That's really the answer!?

Noticing the expression on the girl's face, Lu Zhou, who was a little carried away, smiled, turned his pen and said: "It's very simple to apply the law of Lopida, and the calculation itself is not difficult, speaking of which, you are a freshman?" What major? ”

Chen Yushan's face turned red and whispered: "My ...... for the graduate school entrance examination"

As soon as she said that, her face turned even redder.

It's not shy, it's angry!

It's infuriating!

Isn't it just solving a math problem, what does it stink? I haven't touched this high math knowledge for so many years, so what's wrong with returning it to the teacher? It's really no grace at all, and it deserves to be a single dog! You deserve to be in the library alone!

Thinking of this, Chen Yushan was a little relieved.

As for being a solo library, she selectively ignored it.

"Ugh." Lu Zhou's expression was a little embarrassed, he thought he was in the same grade as himself, but he didn't expect to pretend to be forced to pretend to be on the head of the senior sister.

Just as he was about to say sorry, a heavy cough came from the row in front of the two of them.

Realizing that the voices of her two speeches had disturbed the others, Chen Yushan blushed, stuck out her tongue, and returned to her place with the workbook and scratch paper.

Now Lu Zhou has no chance to apologize, let alone ask for his name and WeChat account......

After sitting there and struggling for a while, he shook his head and continued to pick up the unfinished "Advanced Algebra" and nibble.

How important is it for a girl to study?

Interpersonal relationship?

Sorry, the real school bully doesn't need that thing.

If you upgrade math to LV1, you have the whole world!

Soon, Lu Zhou entered the state and completely left this matter behind, just as a small episode of brushing books in the library.
