Even if it's a fake daughter, you have to be brave

Qing Xiaoyu explained it very carefully, Zou Xuerong quickly learned it, and thanked her in a low voice.

But Shen Yue and Jiang Shiwen still opened their confused and clear eyes, and clearly slapped the four characters "I don't understand" on their faces.

Shen Yue was purely lazy and just wanted to enjoy the feeling of being paid attention to when Qing Xiaoyu gave her a lecture, while Jiang Shiwen tried his best to understand but really couldn't understand.

Qing Xiaoyu looked at the time and began to chase people away, "The class in the afternoon is about to start, are you still leaving?"

Zou Xuerong looked at the time and immediately panicked. Today is her first day of school, so she can't be late. Fortunately, her classroom is next to her.

"Then I'll go first, Yueyue, I'll come to you after school..." After finishing speaking, Zou Xuerong said softly to Qing Xiaoyu, "Thank you too."

Qing Xiaoyu replied politely, "You're welcome."

Jiang Shiwen was very mad, but he also followed Zou Xuerong.

On weekdays, his grades in class are not too bad, just below the middle level, and the teacher never talks about him, and he still feels good about himself.

But today, he was taught to do the questions by a child younger than him, and he still didn't understand it. This is really unbearable!

He doesn't need to learn, but he can't learn if he doesn't understand!

Jiang Shiwen secretly made up his mind to study hard from today, at least next time, he will be able to understand.

The first class in the afternoon was math class. As soon as Niu Kaihuai walked into the classroom, he saw Shen Yue who was sober, and raised his eyebrows in surprise.

Niu Kaihuai thought that he was never a person who would wrong him, he must know what he wanted to know, so he directly asked Shen Yue, "Why don't you sleep."

Shen Yue:?

Seeing that Shen Yue didn't answer, Niu Kaihuai thought she didn't hear clearly, so he asked again, "Why didn't you sleep today?"

Shen Yue was sure that this was asking herself, so she replied, "For a good night's sleep."

Hearing this answer, Niu Kaihuai thought it was reasonable, but not so reasonable.

Seeing Shen Yue's peaceful face, Niu Kaihuai directly wrote a question on the blackboard, and said to Shen Yue, "Shen Yue, come up and solve this question before class, if you can't solve it in this class, you will be fine." Stand up."

My old cow wants to see if you are really sober or fake sober today.

The title on the blackboard is very succinct, demonstrating that:

tan1 > 3/2.

This is a very routine proof question, but it is undoubtedly beyond the outline for ordinary junior high school students who have only learned some basic formulas.

Ye Yin only took one look and wondered if Shen Yue had offended the old Niutou, otherwise why would he ask her such a question.

If you use the conventional method to solve this problem, you need to make the tangent line of y=tanx at x=π/3.

Then use the f(x) assumption to derive the derivative, and prove that tan1>2/3 can only be proved to be monotonously decreasing in the domain of definition.

Now there are only 5 minutes before the class time. If you have not fully mastered the knowledge needed to solve this problem and are very familiar with this kind of problem, it is impossible to solve it within 5 minutes.

Ye Yin couldn't help but sweat for Shen Yue.

However, if Shen Yue doesn't know this question later, can he take the opportunity of speaking the question to talk to Shen Yue.

No, no, no, his thinking is wrong!How could he have such vicious thoughts!He actually cursed his classmates for not being able to solve the problem!

Although the scope of investigation of this question is true that only a few people in the whole class should be able to solve it, but he can't curse Shen Yue.

Really Namo Amitabha color is emptiness is form...

Ye Yin started to recite the scriptures, but Shen Yue looked at the problem in front of her, but only had that sentence in her mind, if she couldn't solve it, she would stand up in this lesson.

Just stand up.

on.

Standing for a class, too tired, no, absolutely not.

She was only 12 years old, and she was supposed to think about nothing, do nothing, and quietly accumulate strength for going to prison in the future, how could she waste time on things like standing up.

She is going to sit! !

At this moment, a fighting spirit suddenly surged in Shen Yue's heart, it was the determination that she absolutely did not want to stand for a class.

She came to the podium, picked up the chalk, looked at the topic twice, and began to search for relevant knowledge points in her brain.

Learn now and understand now.

Shen Yue held the chalk and paused for about a minute without any movement, Niu Kaihuai's heart gradually cooled down.

It's stupid, isn't this girl really unable to figure it out?If she was really punished to stand for a class, would Brother Shen stew himself? !

It's all because Brother Shen misled himself by saying that Shen Yue was a genius in mathematics, but if Brother Shen hadn't said such things that day, wouldn't he not have asked such super-elderly-conceived questions? !

It doesn't matter, even if Shen Yue can't solve it, he can say that he purposely used this question to refresh everyone's mind later, it doesn't get in the way.

While Niu Kaihuai comforted herself, Shen Yue finally started to write.

From the beginning of the first stroke to the end, it was done in one go, without any pause in the middle, and it took less than 1 minute to complete the answer to this question.

The answer is not right, it should be finished.

It was as if the answer was already in her heart, and she just wrote the answer in her heart.

When Shen Yue finished writing the answers, the class bell hadn't even rang.

Niu Kaihuai looked at the answer given by Shen Yue, and was surprised that Shen Yue did not use ordinary derivation to solve it, but used Taylor's formula to scale the inequality.

If this problem is solved by ordinary methods, it is necessary to write five or six lines of equations and convert continuously, but now, in Shen Yue's hands, only three equations are used to solve it.

Niu Kaihuai stared at Shen Yue's answer, checked again and again, and finally confirmed that her answer was correct.

Turning her head, she found that Shen Yue was looking at her obediently, but there was clearly a sentence written in her eyes, can I go back and sit down?

Niu Kaihuai always felt as if he had grasped something, but this feeling was fleeting, he couldn't grasp it, he could only wave his hand to make Shen Yue go back and sit down.

Shen Yue sat back on the stool and let out a long breath of relief.

Fortunately, there is no need to stand.

Qing Xiaoyu leaned over at this time, looked at Shen Yue with the same eyes that she didn't use in the morning, and said in amazement, "Shen Yue, you can actually use Taylor's formula. I only learned this formula from Ye Yin yesterday."

Shen Yue nodded, she also learned it yesterday.

When I was sleeping, I accidentally heard the neighbor talking about this formula, and I memorized it in my mind by the way. I just thought it might be useful, so I turned it out and went through my brain. I didn’t expect it to be solved.

However, even if this cannot be solved, there is another way to solve it, but it will be slower, and it is likely that she will not be able to finish writing before the class bell rings, so she still has to stand.

Fortunately, there is a Taylor formula in my mind.

Although I don't know who told her, but... I am grateful for the gift of nature.

Qing Xiaoyu saw Shen Yue's clasped hands at the side, and approached curiously, "What are you doing?"

Shen Yue's movements remained unchanged, "I am thanking nature for its gift."

Qing Xiaoyu:?

I don't understand it, but it's so cute.

Qing Xiaoyu poked the back of Shen Yue's hand, "Class is over, Lao Niu is watching you."

"I'm so tired, I need to rest."

Qing Xiaoyu and Shen Yue were sitting in the second row, they were plotting loudly, Niu Kaihuai's head hurt from hearing it, and finally he couldn't bear it anymore, "Shen Yue, why are you tired after solving one problem? Just play casually in this class, or listen to the class seriously!"

Niu Kaihuai asked a calculus question, full of confidence.

5 minutes later……

"You can play... Play low-key, don't tell your brother."

So Shen Yue took out a novel in a very high profile and started to read it.

"108 treasures per child, the CEO is very troubled".
