Xueba's Sea of ​​Stars

Chapter 35 Mathematics the Boss
When leaving the cafeteria, Bi Wanqing smiled and said to Wu Bin: "I really want to arrest you now so that you can study the physics of the competition, but do you still remember our agreement?

"Well, I got high marks in all subjects."

"Haha, you can set the high score yourself, but I think it's fine if it's you. Your kid's head will shine."

'Fortunately it's not reflective...'

Wu Bin, who was habitually complaining in his heart, quickly shook his head, "No, no, no, disrespect, disrespect." '

"Don't shake your head, you are indeed smart and hardworking enough, come on, I'm waiting for you to come to me in the office."

After Bi Wanqing finished speaking, he turned and left, but before taking two steps, he suddenly turned around and said, "Oh, by the way, if you want to eat with me, you are still welcome, and the dishes given by your auntie in the cafeteria will be more."

"Hahaha, yes, Teacher Bi." Wu Bin smiled happily.

When Bi Wanqing walked away, Wu Bin was also about to go back to the classroom, but before he took two steps, someone patted his shoulder suddenly.

The frightened Wu Bin suddenly took two steps forward before turning around, and found that the person who patted him turned out to be Su Yun.

"Huh... Teacher Su, don't scare me like this." Wu Bin said with a long breath, patting his chest.

"Sorry, I didn't expect you to be so timid."

"What does this have to do with timidity!? Teacher, this reaction is self-protection in the process of human evolution, okay? It's because the adrenal hormone rises faster, so it will cause..."

"Okay, okay, it's still a set, it's the first time I've heard such a high-sounding novel about guts." Su Yun covered her mouth and smiled.

"Even if you are a teacher, I have to emphasize that this is not timidity, it is adrenaline..."

"Okay, okay, the teacher made a mistake, okay?"

Seeing that Su Yun was willing to admit his mistakes, Wu Bin nodded in satisfaction.

Seeing Wu Bin's complacent look, Su Yun couldn't help saying with emotion: "It's the first time I've met a student like you who can talk to the teacher with eloquence. No wonder so many teachers surrounded you just now, and you were still talking and laughing." , big heart."

"Eh? Teacher, you were there just now." Wu Bin asked in surprise, he really didn't notice the teacher.

"Yeah, I'm sitting at the table behind you. I thought I would have something to say to you after you chatted with those teachers, so I waited for a while. I didn't expect you to talk for so long."

"Ah? Teacher, are you looking for me?" Wu Bin was stunned after hearing this, and then immediately waved his hand and said: "Teacher, I promise, I really didn't tell anything about what happened that day in the infirmary."

When Wu Bin spoke, the two aunties who had just walked out of the cafeteria happened to hear them, and immediately showed expressions of "Ying Chuangsting" and "a rowing boat" at the same time.

Su Yun hurriedly said after seeing it: "Who told you this!"

"Then what else is there?"

Su Yun was going to die of anger at the moment. Looking at the fast pace of the two cafeteria aunts, she was obviously very interested in the follow-up development.

"I want to talk to you about the learning problems of the senior three students you mentioned last time."

"Oh...is it useful?"

"Well, some students really like the simple and rude key points you mentioned, and some are even willing to come to me."

"That's good."

"So I have some new questions for you."

"That... teacher, you are the teacher, right?"

It was really the first time for Wu Bin to meet such a teacher who was "not ashamed to ask".

Su Yun blushed after hearing this, "But I teach students like you." Su Yun said with a sigh: "Actually, I have also tried to talk to those students in our class, but they are always too nervous. I also rarely express my own opinions, which is not like you, old fritters."

"Hey, teacher, it's not good for you to ask me for help and hurt me a few words."

"I'm praising you. Would you like to help the teacher again?"

"The teacher makes a request, and the students dare not refuse."

For a teacher like Su Yun who is willing to "ask without shame" to improve her teaching level, Wu Bin really can't think of any reason to reject her.

"Then thank you first, teacher."

After Su Yun finished speaking, she glanced at the back and found that the two cafeteria ladies had gone far away, so in order to prevent Wu Bin from "speaking surprisingly" again, she said to him: "Then you go with the teacher, don't worry, there will be no delay." You have too much time."

After nodding to follow Su Yun, Wu Bin originally thought she would take him to her office, but unexpectedly, he came to the chemistry laboratory. It was lunch break, so there was no one there.

But Wu Bin figured it out after a little thought. If other teachers saw Su Yun asking a senior high school student about teaching methods in the teacher's office, the style of painting might be a bit weird.

"Then I'll ask directly. Last time you told me that you suddenly worked hard to study because you discovered the joy of learning. Can you give an example? What kind of fun suddenly attracted you?"

'It seems that this teacher still hasn't given up on the idea of ​​bringing poor students up. '

After thinking about it, Wu Bin tried his best to recall his views on knowledge since he dealt with it for more than a month.

"Teacher, have you ever played games?"

After thinking for a while, Wu Bin asked.

"Game? Super Mario?" Su Yun replied.

"Yeah... forget it." Wu Bin nodded reluctantly and continued: "The game is one level after another, and the same is true for learning. Take the calculus that I just came into contact with. It makes me a little bit tired. Understand why I studied high school mathematics."

Su Yun was listening quietly, not intending to interrupt Wu Bin.

"I personally think that the core idea of ​​calculus is to divide an irregular shape into countless infinitesimal microelements, and then add these microelements to get the total amount, which is very useful for solving various formulas."

Su Yun listened and nodded, expressing her approval.

"Then my point of fun is this. Set calculus as a big boss. If you want to defeat it, you must have equipment, skills, and..."

Seeing Su Yun's bewildered expression, Wu Bin stopped, thought for a while, and continued: "Then let's put it another way, it's a tree of knowledge, I have to light up every branch of it, Only in this way can I have enough ability to defeat the BOSS, can you understand?"

"Well, I understand, you can continue." Su Yun nodded.

"Anyway, most of the students must understand." Wu Bin is still very sure of this point. Although he is not interested in games now, the students who are interested still account for the majority. This example must be the easiest for them to accept.

"Okay, so the first level, starting from the set, why do you need to learn the set? It is because the domain and value range are required to accurately express a function, so after passing the first level of the set, I lit up this skill , and mastered it, right?"

Su Yun couldn't help but nodded after listening, and praised: "It's interesting, let's go on."

"Mastering sets is to challenge functions, and many limit properties of functions are obtained through sequence, so in order to challenge functions, I have to pass the level of sequence.

Wu Bin gestured with his left and right hands as he said, "After I have mastered the two skills of sequence and set, I will have the ability to challenge the little boss of function. After defeating function, I will be able to pass the level of derivative. And the derivative is differentiation, which is the premise of learning calculus."

"Now, I have the ability to challenge the big boss of calculus, but for some higher-level calculus, these abilities alone are not enough. For example, the weakness of some calculus bosses is Euler's formula, and in order to learn Euler's formula , you have to pass the level of imaginary numbers first.”

Hearing this, Su Yun could only nod her head.

"Actually, I've said so much just to prove one thing. High school is by no means an exam-oriented education. Every level of study is a loop, one level after another. If you don't defeat the boss of this level, go to it by force." Challenging the next level, this is the same concept as a level 10 trumpet in white equipment who insists on fighting a level 30 dungeon boss."

Seeing that Su Yun was in a dazed state again, Wu Bin had no choice but to stop and explain: "In short, you and the students must understand what you said, or you can choose to go home and check the equipment, dungeon, boss and other keywords online. .”

"Okay, I'll check it out." Su Yun nodded seriously, and then said: "It's really amazing that you can sum up this theory. With new concepts, many students in our class do not have a solid grasp of some basic parts, so they always focus on big problems."

"Hey~ This is called head iron, a leapfrog challenge, and then being beaten by the boss without any confidence left. In fact, the style of play is not correct. Some geniuses can indeed pass through with fancy operations, but ordinary people can't. , well, I know teacher, you don’t understand again, why don’t you go home and look up the words used in various games, and we will discuss it next time?”

"Okay, then it's settled, and I'll come to you after I understand this." Su Yun nodded several times after finishing speaking, "Thank you for your answer, it's very helpful to me, I'll come to you next time I will treat you to dinner in return, then I will go back to the office first, goodbye."

"Okay, goodbye, teacher."

The teacher and the student waved goodbye, and Wu Bin stretched and walked towards his classroom.

His next goal is to defeat the boss of chemistry.

When they returned to the classroom, everyone in the class who saw him greeted him one after another. They didn't ask much about the competition, after all, it was another world for them.

"How did you do in the exam? I see that bastard Zhang Qiu came back looking unlovable, isn't it difficult?"

When Wu Bin returned to his seat, Gu Fan leaned over and asked in a low voice.

After hearing this, Wu Bin nodded solemnly, then leaned closer to Gu Fan and whispered, "It's quite difficult, and I can probably get a perfect score in the exam."

After hearing this, Gu Fan was taken aback for a moment, then immediately reacted and shouted: "Fake it, keep pretending!"

"Whatever you want~"

Wu Bin shrugged and took out his chemistry book from the second year of high school.

But after a while, Gu Fan leaned over again and asked, "Can you really get full marks in the test?"

"Shh, let me study for a while first."

Wu Bin pressed his index finger on his lips and said softly to Gu Fan.
