Fang Chao, who has enough talent in mathematics, lost his bias in measuring Chinese and mathematical relationships, which made him almost on the verge of collapse.

After finally comforting them, Fang Chao was sweating profusely.

It took more than half an hour to put Fang Chao back into work.

【Based on the ideal state… let f(x)f(y)…】

【When the domain is (-∞,0), then…】

【And when the domain is in the interval (-1,0), then…】

...

Fang Chao was writing while scratching his ears and his head, on the verge of collapse.

Writing articles and writing mathematics are completely different things. It will take at least a long time for Fang Chao to get such an article, which is undoubtedly a torture for Fang Chao.

But the road to academic masters is itself difficult, and Fang Chao has realized something.

The progress of the article was completed by 23%, which took Fang Chao a full day.

Lao Zheng hadn't seen Fang Chao for several days, and he couldn't help but feel a little worried. After all, it's been almost ten days, so he took the initiative to call to inquire.

"Fang Chao, you have been taking leave for several days, are you okay?"

"It's okay, teacher, I should have to take another four or five days off. When I get this matter done, I will return to school immediately."

"Hey, although I don't know what you are doing, it should be a remarkable thing. Come on."

"Thank you, teacher."

"By the way, the school sports meet is about to start in ten days. You have signed up for the 8,000-meter long-distance race, and you have not trained recently. Will there be problems with the school sports meet? If there is any problem, the main focus is on participating. Just run two thousand meters and the rest will be said to be out of strength. Anyway, the school cannot force students to actually run the 8,000 meters."

Lao Zheng is still very concerned about Fang Chao's physical condition, after all, this is not an ordinary student.

Fang Chao felt a hint of warmth in his heart, "Teacher, I'm fine. Eight thousand meters is not under much pressure for me. What really makes me a headache is that I have to write an article now... It took me a day to write one-fifth of the progress. If I have to finish writing, it will take five days to guarantee it... I am full of fanaticism about knowledge, and mathematics is like a fatal temptation to me. However, when I was editing the language about this, I was in trouble. Teacher, can you help me? It's too difficult for me."

Fang Chao really wanted to ask for help, and wanted to express his unhappiness. This was the first time since he kept getting results.

Teacher Zheng couldn't help but feel a little funny, "Fang Chao, you said this as if you were teasing me. What else can stump you? Based on your current grades, even if you don't take the college entrance examination, you can easily enter Tsinghua University and Peking University. You told me that it's too difficult, so what do you think of the students in the class?"

"Teacher, this is really a stumbling block on my way forward... But if I don't get it done, I will definitely be trapped in this place."

Teacher Zheng couldn't help but say curiously, "I'm a little curious about this. Then tell me, what are you doing?"

Fang Chao said, "Teacher, it is not a thing. It is about finding function values ​​in the band definition domain, referred to as waveguide functions for short. My senior brother said that there is no problem with my argument, but it is best to publish it in the mathematics journal. This will have certain benefits for me to enter Princeton in the future. I said that it will be published in the Mathematics Annual Edition·A, and then it will be more likely to publish it in the SCI. So I thought about getting this matter done. I said, Teacher, can you help me? Or give me some advice?"

Teacher Zheng said, "Well, then that's it. I'll give you a few more days of vacation. I remember to come back to the school sports meeting to add some fuel to the classmates. After all, you are still the class monitor of Class 5 and you can't not see you at critical moments."

Fang Chao said, "Don't worry, teacher, I can definitely go back to school during the school sports meeting."

Teacher Zheng, "Then let's do it first. I have something to do here, so let's have a break first."

Doudou~!

This is how Lao Zheng does things. He is always decisive and considerate. Fang Chao is not disturbed when he gives him a holiday, but Fang Chao always feels a little weird. Lao Zheng doesn't seem to say he wants to help him...

never mind.

After all, I have to deal with my own affairs.

What is curious is that Fu Lingyan also sent a WeChat message to care about herself.

Fu Lingyan's question was very simple: "I said to you, squad leader, if you are fine, you have to make a squeak, right? You can't see you. After you become a class monitor, you will become a hand-off manager. Will your school sports meeting still appear?"

When Fang Chao saw this, he couldn't help but smile bitterly. As expected, he was the class monitor. Since he became the class monitor, he has been in the class for almost a few times.

So after thinking about it, Fang Chao went back to the word.

【squeak!】

Zhang Ling also looked for Fang Chao, and the way she asked was simple: "Senior, I haven't seen you appear on the playground for a long time. Can we still run together in the future? (ps: Senior Fang Chao, I know your true identity)"

Real identity?

My true identity?

What is my true identity...

Fang Chao was a little confused, but he quickly realized that three black lines appeared on his forehead. Zhang Ling, you never knew my identity as a top student? Did you know recently?

No wonder I always ask if I am from the school team and try every means to get me to join the school team. So that's how it is...

"What she said is that she is afraid that I will not run with her in the future? What are you thinking about~"

Fang Chao was a little helpless. Running was a compulsory course for him every day. Even if he didn't meet Zhang Ling, he would not break the cells of his exercise. If he wanted to become a strong academic master, he had to have strong physical conditions as the foundation.

But Fang Chao was not disgusted with Zhang Ling's words, and even had a special emotion for her. This emotion was not love, but a difficult statement. It can be said that Fang Chao missed her a little, but this kind of thinking was because every time Zhang Ling was by her side, Fang Chao could find some inspiration, for example, this time the waveguide function was obtained from Zhang Ling.

So, if this is possible, Fang Chao is still willing to have an in-depth understanding with Zhang Ling and become a good friend. In this way, Fang Chao will not have to worry too much about his inspiration in mathematics in the future.

So Fang Chao replied, "No, I'm busy with math problems these days. It's better to wait for this period of time. I'll run together if I have the chance in the future. Don't I owe you a movie?"
Chapter completed!
