Chapter 18: Everything can reach Lópida?

"Your English teacher is still focusing on grading, this class will be changed to physics."

The words of physics teacher Wang Jianjun stunned Lin Xun and Wang Zihao.

Yes

The slap in the face will have to wait.

The two of them sat listlessly in their seats.

At this moment, they were not looking forward to Qing Yun’s face.

It feels a bit boring.

Who are you slapping in the face?

Tang Qianying was a little sleepy.

She had two classes in a row, and there was also the most brain-burning math class. There was no break between classes, and her brain was on strike.

Using the books stacked high on the desk to cover her body, she stretched and said, "I'm so sleepy today."

A standard stretching exercise to let the body in front of her Her curves are on full display.

Qin Manman rolled his eyes when he saw this, leaned sideways on the table, and echoed, "I'm a little sleepy too."

Qing Yun's sight was blocked by the back of her head. He sighed inwardly and began to carry the creature on his back.

Let’s see what happened

Your position as a doctor will not be lost.

This woman is good at everything, but she is a bit stingy

Tang Qianying took out a bottle of Fengyou essence and poured it on her, "I have to wake up quickly, it's a physics class."

She had planned to relax during this English class.

English is her strong point, and her score has never been lower than 145 since she entered high school.

Qin Manman asked her to drop some Fengyou essence on the toilet paper and put it aside. “It’s just right to study some simple subjects when you’re not awake.”

The one in the front row Guan Xiaohe turned her head angrily, "Manman, I think your skin is itchy today." What about competition

Only mothers with high IQs can give birth to children with high IQs, don’t you think so, Qing Yun?”

Qin Manman’s hair suddenly exploded, with a pair of long legs underneath. Kicking the chairs of two unscrupulous besties.

When Tang Qianying heard this, her expression became condensed. She looked at Qin Manman who was making a fuss and was filled with surprise and uncertainty.

She saw it

She saw it

A pair of comic eyes narrowed.

Good Qin Manman

I didn’t say I wanted to rob you, so I just left it here to play dirty tricks on my sister, right?

Believe it or not

p>

Tang Qianying's shoulders suddenly slumped again.

Forget it.

If we get along with each other in different positions, I would be able to defend myself.

My best friend.

The reason why best friends become best friends is because, as the saying goes, "birds of a feather flock together, and people flock together."

Best friends have similar interests, appreciation levels, and looks, as well as temperament, personality, and behavior, otherwise they would not become best friends.

What do you like when both parties are similar to each other in all aspects?Maybe that's what she likes.

The converse is also true, so it is easy for men to fall in love with their girlfriend’s best friend.

Tang Qianying sighed inwardly and lowered his head with a complicated expression.

Okay, Manman, I admit, you didn’t make a mistake.

I do like him.

But, Qin Manman

Can you really stay with him for a long time?

We are best friends, and you don’t care about me. Don’t you understand?

“Students, the second-diagnosis test paper is still being marked. You must have done all the after-school questions assigned last time.”

Wang Jianjun stood on the podium and began to turn the pages in his hands. of papers.

"I forgot about it"

Tang Qianying immediately woke up and did not touch a word of the homework assigned before the second diagnosis exam.

"Sister Ying, I have good news and bad news. The good news is that I didn't do anything either." Zhou Li, who was diagonally in front of her, turned her head and smiled at her.

"What about the bad news?" Tang Qianying felt a little calmer after hearing that none of the study committee members had done anything.

Zhou Li smiled and said, "The bad news is, I can finish it in 3 minutes."

Tang Qianying was speechless.

These best friends are ganging up to bully me today, right?

"Qin Manman, please talk about this question."

Wang Jianjun meets the back row There was some commotion, so I simply named Qin Manman, the center of the commotion.

Qin Manman quickly retracted his legs and stood up with the question sheet, "As shown in the picture, a long enough horizontal conveyor belt always moves to the left at a speed of v=3s"

Qin Manman looked at the questions, "Mr. Wang, because class has just started, I think the students I needed some time to focus on the class, so I read it with the questions." Wang Jianjun smiled and nodded, worthy of being the first in the grade.

This is how he does things. Thoughtful

That kid Qing Yun is really cheap.

Don’t mention it, the two of them look quite good together.

Qing Yun is his favorite disciple, so naturally he will be pleasing to his eyes.

However, it’s a bit weird.

Why does this stupid boy look at his own wife like this?

At this moment, Qing Yun was stunned when she looked at the blank question sheet in Qin Manman's hand next to her.

My mother-in-law doesn’t seem to be that honest.

The reason for reading the questions is because she needs time to do mental calculations.

“The first question is the common speed of the ball and the wooden box at the moment they meet. We assume that the speed of the first ball and the wooden box moving together is v1 at the moment after the first ball and the wooden box meet. According to the law of conservation of momentum, After substituting the data, the answer is 3s.

The second question actually examines displacement. Let’s assume that the distance between the point where the first ball meets the wooden box and the left end of the conveyor belt is s”

Wang Jianjun applauded, "This question isThe ideas and answers are both correct. Qin Manman explained it very well. "

Just as Qin Manman was about to sit down with a reserved smile, Wang Jianjun added, "Just remember to do your homework next time. "

The classroom suddenly burst into laughter, and Qin Manman blushed, feeling embarrassed sitting there.

"In the first half of today's class, we did Jiangsu rolls. The final question, the review in the second half of the class. ”

After Wang Jianjun asked everyone to start doing the questions, he, like Li Fangping, told Qing Yun to do other subjects.

This kind of treatment made Qin Manman a little envious.

In physics, she couldn't get a perfect score, so she had to do the questions honestly.

Wang Jianjun also left the classroom. He had just finished reading the paper and hadn't gone to the bathroom yet.

Qing Yun in the classroom felt helpless.

After doing the liberal arts questions for almost two hours, his mind was a little numb.

Qin Manman also knew this. Let him rest.

After quickly answering the first short question, Tang Qianying started to stare blankly at the last two questions.

She was sure. , this is a topic she cannot afford.

Yang Yuejing’s remarks just came to her mind again.

She snorted coldly. Okay

It seems that her anxious behavior for Qing Yun in math class was considered a success in the eyes of caring people.

She glared at Qing Yun angrily. Unexpectedly, their eyes met across Qin Manman's back.

Qing Yun grinned at her, "Give me a look at your math paper, I'm about to fall asleep." "

Tang Qianying didn't want to pay attention to him at first.

But when she thought of the word "female competition", she felt a fire in her heart, and she handed over the paper by mistake, "Why is it my paper?" "

Qing Yun took the paper and said sincerely, "I really like studying your ideas for solving problems. ”

Tang Qianying, Qin Manman in the middle, and the few people listening eavesdropping, all looked confused.

What ideas can Tang Qianying have for solving problems in mathematics

p>

“Your idea makes me feel like my eyes are shining brightly, it is a way to solve the problem that I could not have imagined. ”

Tang Qianying

Qin Manman

Chen Yue

The faces of the people eating melons were collectively filled with question marks.

“Every time I will solve the problem according to your problem-solving ideas, but I can’t solve it every time. ”

Qing Yun’s words made everyone unable to hold back their laughter.

Fortunately, it was a classroom, and although the teacher was not in the classroom, they did not dare to be too presumptuous.

Tang Qianying was so angry that her head was about to smoke, and she stared at the hateful little brother in front of her.

Qing Yun shook her head and concluded solemnly, "Sister Ying, I have to say. , sometimes you are really a genius, why can you always come up with these ideas that cannot solve the problem?"

Tang Qianying was immediately furious., Qin Manman went to scratch him.

Guan Xiaohe chuckled and said, "Youngest, you and Manman are really made for each other. Even if you look at Qianying, your tone is exactly the same."

Qin Manman looked helpless. She reached out and hugged Tang Qianying, turned around and scolded Qing Yun, "Say less."

However, a smile appeared at the corner of her mouth.

This stinky man is quite wise.

Tang Qianying bared his teeth and claws for a while, and then stopped when Qin Manman stuffed him with another lollipop.

But what no one noticed was that under her long bangs, the corners of her eyes were curled up with a smile.

She found that although such a fuss made her very embarrassed, the secret targeting of her by several best friends was eliminated.

The comic blinked twice, feeling a little confused again.

This bratty brother couldn’t have done this on purpose, right?

She glanced at Qing Yun suspiciously, only to see him burying his head and touching his chin, looking at his test paper carefully.

Tang Qianying murmured in her heart, what's so good about this?

Suddenly, an idea flashed in her mind.

Isn’t this guy trying to help her improve her math score?

Tang Qianying turned her head and bit her lip quietly, feeling excited and disappointed at the same time.

The exciting thing is that as we all know, Qing Yun not only has good mathematical skills, but also has the reputation of a gold medal coach. Maybe he really has a way with his own mathematics.

What’s disappointing is that, damn, he’s just a stinky younger brother

The most hateful thing is to tease people unintentionally

Scumbag

But

If you are careless, what's the use of improving my math?

"Sister Tangying, I have already written down the solution ideas for you for the two big questions you got wrong. By the way, I also asked a few similar questions to consolidate, so I won’t go wrong next time I encounter this kind of question.” Under Qin Manman’s attention, he originally wanted to call Tang Qianying Tangtang according to his past habit. Qingyun was forced to change his words.

Tang Qianying thanked him and took the draft paper he handed over, sitting on his seat and looking at it with interest.

Qing Yun’s solution is very clever, but she has no interest in mathematics at all.

Otherwise, we would not have been in such a shaky state.

Whether she works hard or not at this time will not make any difference to the result.

She did not want to leave Xishu, where she was born and raised, to study in a different place.

As for the two local 985 universities, Shu University and Chengdu Electrical Engineering, their scores in Western Shu are not high.

Especially Shu University, at this time, it only has about 30 points on the key line.

This is a level she can never fall below.

"Take a look at these three theorems." Qing Yun handed over a few more pieces of paper.

Tang Qianying took it with a numb expression.

"Cauchy's Mean Value Theorem"

"Lópida's Law"

"Taylor's Formula"

Tang Qianying looked at the draft paper in her hand in confusion, "This is the content of advanced mathematics."

Qing Yun snorted, "Remember one sentence, advanced mathematics Looking at it, there is no secret. ”

A pair of comic eyes suddenly narrowed, “What do you mean, you are standing in the clouds looking down at all living beings”

Qing Yun almost choked to death from her.

Although he also wants to look down at her, now is definitely not the time.

Qin Manman is still there in the classroom.

There will be many opportunities to not only look down at her. Twin ponytails, and a mirror next to it

He swallowed and explained helplessly, "To put it simply, if you use advanced mathematics to view the world, there will be no secrets in the world. ”

Qin Manman curled his lips and said, “If you use advanced mathematics to do college entrance examination mathematics questions, even if you get it right, half of the points will be deducted from the examination paper in Xishu Province. ”

“Why don’t you explain why you don’t give points and the teacher can’t do it?”

Qin Manman’s voice seemed to have been practiced and was very penetrating.

Wu Jun, the gold medal winner in the national mathematics competition, raised a question. >

Qin Manman knew that this guy was also a recommended student and had not gone through the review mode switch, so it was normal not to know about it.

But she didn’t want to explain it.

She didn’t want to explain it. The other men explained.

Qing Yun patted the footprints on his pants and said helplessly, "Lao Wu, let's use your favorite Law of Luo Bida as an example.

Middle school mathematics does not talk about the definition of limit. ”

Wu Jun was dissatisfied, “Why didn’t you mention it in the derivative? It’s already used.”

I’m using it all the time, why don’t you tell me that you didn’t mention it

p>

Yang Yue was also confused, "Isn't the process of approaching the limit something that is written in our textbooks? "

As soon as these words came out, Wu Jun patted his head and said, "I understand. "

"What do you understand?" Yang Yue was confused.

I was really agreeing with your point of view, but then you said this

Co-authored I look stupid

Wu Jun smiled at Qing Yun, turned around and explained, "Limit is a concept in advanced mathematics differential calculus courses, and in our high school textbooks, "approach" is considered to be the limit. Yes, this is essentially correct.

But high schools generally believe that approaching means equaling. "

Guan Xiaohe on one side was stunned, "Isn't it?"

The classroom started to chatter.

They are all good children who love to learn. When they meet new people, Knowledge points, instinctively began to pay attention,

Wu Jun scratched his hair, "Young man, why don't you explain it to me, I'm worried that it will confuse them. ”

He is very self-aware of himself. He can solve problems, but he cannot explain them.

This is originally super-outline knowledge, and he can explain it to his classmates.Confused, he cannot bear this responsibility.

Qing Yun patted his trouser legs again and walked to the podium, "Let me tell you, our high school books have some knowledge of calculus.

But they were all originally going to college. The most basic part of advanced mathematics that Li Cai learned.

This part of knowledge is very awesome if you dig deeper. It is also the reason why advanced mathematics is called advanced mathematics. < /p>

However, here, I will only talk about the limits we just discussed, and please note that it is only suitable for students who have the ability to learn."

"Then you still let me learn. " Tang Qianying spoke angrily. Please remember to collect it. The website is the latest and fastest without anti-theft. To find books and add books for free, you can join the qq group 952868558
