Xueba's life simulator

Chapter 22 The Blushing Shen Qingqiu
Zhou Ming took the mathematics postgraduate entrance examination book from Liu Xiao as usual, and looked at the question he asked.

"I didn't understand the answer. I always thought that Brother Zhou's method was much more reliable than that answer." Liu Xiao flattered her.

[Assume Р is the moving point on the ellipsoidal surface S: x+y+z-yz=l, if the tangent plane of S at point Р is perpendicular to the x0y plane, find the trajectory C of point P, and calculate the surface integral ( x + √3)ly-2zl/√(4+y+z-4yz) ds, where ∑ is the part of the ellipsoid S above the curve C. 】

"This question is actually quite simple. You see, in most cases like this kind of question, first set an F(x, y, z) to represent the function containing x, y, z, and then use the known Conditions to set up several equations of equality, if there are unknown constants, first calculate the unknown constants according to the listed equations. Then use the equation to replace the three unknowns with two unknowns, generally using x and y to replace z.

Here you just move the 1 on the right to the left.

In this way, according to F(x, y, z) = 0 to find...

Find an equation through the normal vector, and then use the condition that P is on the surface S to get this equation...

......"

After Zhou Ming finished reading the topic, he soon began to explain the disintegration process to Liu Xiao.

In the process of listening to Zhou Ming's explanation, Liu Xiao's puzzled again. During the process of this lecture, he asked Zhou Ming for a long time about the origin of some of the steps that Zhou Ming omitted, and finally he understood.

"Actually, the problem-solving ideas for this kind of questions are not bad. You do more questions, and you will become familiar with them after doing more."

After Zhou Ming finished talking about this question, he was about to go to bed while he was talking, but he heard Liu Xiao say again, "Wait a minute, wait a minute, look at this question and this question again, I didn't understand these two questions. There is no detailed explanation on the answers to the two questions, and a bare result is directly given."

Looking at the problems pointed out by Liu Xiao again, Zhou Ming explained them to him in detail.

"Liu Xiao, Zhou Ming is helping you so much, you have to treat him to dinner."

"It's okay if you don't invite someone to dinner. You can be his boyfriend or girlfriend, haha."

"Why, you want him to grab a man with our school bully?"

As soon as Zhou Ming helped Liu Xiao solve the math problem, Liu Tianlu and Zhao Letian were booing beside him.

But they were right about one thing.Because of Zhou Ming's help, Liu Xiao often invited Zhou Ming to dinner when he was in the last semester.

Although Liu Xiao invited meals from the canteen, which were not expensive, it was still his wish. Zhou Ming also tried to refuse, but Liu Xiao insisted and Zhou Ming allowed him to invite him.
"Zhao Letian, did you not enjoy father's love during the winter vacation, and you can't wait to experience father's love?" Zhou Ming got out of bed as he said that.

"Don't, don't, I'm wrong, can't I be wrong, brother, brother Ming." Zhao Letian still hoped to copy Zhou Ming's homework, seeing that Zhou Ming was going to come down to mess with him, he hurriedly begged for mercy.

"How are you reading the civil servant exam? Can you pass the exam? Learn more from Liu Xiao." Zhou Ming didn't plan to go down at all, and it was just a show just now, it was just a daily play in their dormitory.

"I watched it, but it gave me a headache. I really don't understand. Why do you need to know everything to take the civil service exam? I just want you to know astronomy and geography." Zhao Letian complained.

"That's for sure. Do you think civil servants are so easy to take the exam? Don't you look at how many civil servants take the exam every year, millions of them."

……

In the next few days, Zhou Ming's life was not much different from before. It was just that the number of questions asked by teachers during class increased significantly. Most teachers would ask Zhou Ming from time to time during class. They were probably also surprised by what he had learned last semester. I wanted to see Zhou Ming's final exam results to see if he really had the real stuff.

Less than a week after school started, Zhou Ming received a message asking him to become a tutor.

It was Mr. Hu who contacted Zhou Ming, the one Zhou Ming went to when he was a tutor for the first time last year, but this time he contacted Zhou Ming not to ask Zhou Ming to be a tutor for his son, but to recommend someone to Zhou Ming.

It turned out that after Mr. Hu's child received Zhou Ming's one-semester tutoring, his academic performance improved a lot.

Later, during dinner at the company's annual meeting, colleagues gathered around and talked about their children, and Mr. Hu also told about his own children.

The boss of their company heard that he hired a tutor, and his children's grades improved a lot, so he also wanted to contact Zhou Ming, and asked Zhou Ming to teach his children to see if he could help his children improve too. Take a look at your academic performance.

"Mr. Hu, I have a lot of classes this semester, and I'm usually busy on weekends and weekends. I'm afraid I don't have much free time." Zhou Ming's reply was a tactful rejection of the request to be a tutor.

"Mr. Zhou, don't rush to refuse. Our boss's salary is definitely better than mine. If you are not satisfied with the salary, you can discuss it with him. I have given your contact information to our boss, and I will I will give you his WeChat account, and he will add you within two days, so it is not too late for you to chat with him before deciding not to go." This Mr. Hu advised Zhou Ming.

"That's all right, I'll talk to your boss first." Zhou Ming heard that the salary might increase, and he thought about it, so he didn't say anything.

"Well, our boss's surname is Shi, and this is his WeChat." After Mr. Hu sent this message, he recommended his boss's WeChat to Zhou Ming.

Sure enough, as Mr. Hu said, their boss added Zhou Ming's WeChat on the second day after Mr. Hu contacted Zhou Ming.

Boss Shi briefly talked about his situation first, and then offered Zhou Ming a price, asking if Zhou Ming would like to teach his daughter.

Boss Shi offered Zhou Ming 300 yuan per hour, two days a week, Saturday and Sunday, two hours a day.

This price surprised Zhou Ming, 300 yuan an hour, two hours a day, and two days a week. In this way, Zhou Ming could get 1000 or [-] yuan in just four hours a week.

"These bosses are really rich. They hired a tutor to pay such a high price casually." Zhou Ming was happy and surprised at first, but he soon felt that things might not be that simple. It's too reliable, but he doesn't have any evidence to prove what's not reliable.

Just when Zhou Ming was still struggling, Boss Shi over there sent another message.

"However, because of me, my daughter has a bad temper recently. I hope you will be more considerate and considerate. Tomorrow, Sunday, do you have time? If I have time, I can make time. I will be on XX Road at two o'clock tomorrow afternoon. Meet and discuss in detail at the Blue Harbor Cafe."

"I have time tomorrow afternoon and can go." Zhou Ming replied with his head lowered in the library.

Shen Qingqiu at the side saw that Zhou Ming had been typing with his head down for a while, and he didn't know whether he was curious or worried, so he also stretched his neck over, wanting to see who Zhou Ming was chatting with.

Seeing Shen Qingqiu like this, Zhou Ming realized why she didn't want to fall in love with him before the postgraduate entrance examination.

Because Shen Qingqiu is a person who, once he has someone in his heart, will pay attention to him from time to time.

If too much attention is put on Zhou Ming, Shen Qingqiu will naturally be distracted from reading, and if he is distracted from taking the postgraduate entrance examination, he will easily fail to go ashore.

"This is a boss who asked me to be a tutor, Nuo, look." When Shen Qingqiu's small head approached, Zhou Ming also moved closer to her ear, and whispered in her ear.

While talking, Zhou Ming stretched out his hand in front of Shen Qingqiu, and showed her his chat records one by one.

While Shen Qingqiu felt a warm current blowing into her ears and brushing her cheeks when Zhou Ming was speaking, she suddenly felt an electric current running through her whole body from top to bottom, and her face, ears and neck also turned red all of a sudden.

Shen Qingqiu hastily retracted his neck, and didn't even bother to look at Zhou Ming's cell phone.

"Pfft!"

Seeing Shen Qingqiu's appearance, although Zhou Ming tried his best not to disturb the students studying around the library, he still couldn't hold back his laughter in the end.

Hearing Zhou Ming's chuckle, Shen Qingqiu felt even more embarrassed and could only bury his face deeply into the clothes on his chest.
