I did nothing this week except mathematics and high school mathematics.

The difficulty of writing a "Guidelines for High School Mathematics Problem Solving Skills" is much higher than I thought.

The difficulty lies in how I improve their math grades in languages ​​they can understand. Perhaps this is the field that math teachers and auxiliary material writing experts are good at, not me.

I have studied the college entrance examination mathematics test papers for nearly ten years, but the reference value ten years ago was not very meaningful.

I got full marks in all of these ten college entrance examination math test papers in 30 minutes, but I am a loser because I have used a lot of math knowledge and skills outside the high school syllabus.

I tried to use functional analysis and divergent series to analyze these ten college entrance examination papers. This took me 13.5 hours, and I had no food or drink. I went to the toilet once in the middle and almost fainted on the toilet.

I assume that the college entrance examination paper is a special "function", which follows a certain rule I "imagined". I established their entire composition of the closed area, and used the oscillation series in the divergent series to approximate the "college examination paper function".

The result surprised me and was very curious. I refined a "universal method"... In fact, it should be considered a semi-finished product.

"General method" is just a logical framework. I need to use the most basic high school mathematics knowledge such as sets, trigonometric functions, stereoscopic geometry, plane analytical geometry, algorithm preliminary, sequence and other basic high school mathematics knowledge to enrich its flesh and blood.

This meticulous work may last for several months or even more than a year.

Fortunately, the Euler formula and closed surfaces, symmetry and group in Option 2-3, as well as the matrix and transformation in Option 4-1, helped me a lot.

I strive to complete the first draft within this year.

So be low-key and don’t brag. I can’t fulfill my promise within a week. What a painful realization.

This also made me more deeply realize the profoundness of mathematics. Even elementary school mathematics teachers are worthy of our respect for the rest of our lives.

And mathematics itself is worthy of our long reverence.

By the way, the paper I wrote, "Some Solutions for Linear Non-Horizontal Differential Equations of Second Order Constant Coefficients", has been submitted to the editorial department of "Mathematical Innovation Journal".

Originally, I wanted to contribute to a national core journal such as Journal of Mathematics, but at the suggestion of Teacher Zhang, I chose Journal of Mathematics Innovation as a trial village for beginners.

That’s all for today, my mom asked me to have a meal.

October 15, 20XX.

...

Shen Qi finished writing the latest academic master's diary and went for a meal.

The next day, Shen Qi came to the classroom of Class 2 of Senior High School (2). He told the students very sorry: "I promised your problem-solving guide. I encountered some technical problems during the writing process. I need some time. Please wait patiently."

Gu Xiaodan asked: "Big Boss, how long will it take? Can it be done within this month?"

Shen Qi shook his head: "No, it will be December at the earliest."

Gu Xiaodan collapsed: "No! It's December, I'm almost finished my senior year of high school!"

Chen Xiaoting was a little disappointed, but he could understand: "Shen Qi was kind to help us, but this was not an obligation he had to fulfill. Gu Xiaodan, do you think it's so easy to write a math guide? Shen Qi is a senior high school student like us, and he is not a writing expert who specializes in this."

Shen Qi glanced at Chen Xiaoting, and it was my deskmate who understood me, Gu Xiaodan was too utilitarian.

"No! Boss Shen Qi is different from us! I don't ask for a full score in math, I just want to get a score of 120 or above!" Gu Xiaodan beats his chest and stamps his feet.

"Gu Xiaodan, call me, and then call me or not, I will beat you to mentally retarded?" Xu Rui in the back row roared angrily, rolling up his sleeves and trying to make trouble.

"Beat, Xu Rui, you fight. Anyway, I'm not far from being mentally retarded. I can't even get 120 math. I can kill me." Gu Xiaodan looked like he was reluctant to live.

Xu Rui walked to Gu Xiaodan with murderous intent: "Damn, I got 37 points in math last time. What did I say? Do I blame others? According to you, I am also mentally retarded, and I have to die?"

"Xu Rui, you have sports expertise, which is different from us! And I have nothing, average grades, not handsome, and taller than 165. That thing is not as big as yours. I... I'm just a waste..." Gu Xiaodan said depressedly.

Some girls in the class laughed, such as Yan Beibei. Other girls were embarrassed and pretended not to hear anything, such as Chen Xiaoting.

"No, Gu Xiaodan, at least you have a sense of self-knowledge." Xu Rui was immediately dissatisfied. He liked others to praise him for being big, especially in front of girls.

Xu Rui not only calmed down, but also gave advice: "Gu Xiaodan, don't ask Shen Qi about math problems, you can't understand your solution, even me... Of course, I can't understand even more. Go and ask Teacher Zhang, he is our math teacher and has the responsibility to help us improve our math grades."

"Come on, every time I ask Teacher Zhang, he only has one sentence. I can't even have such a simple question? Have you listened to my lecture seriously? Get out, get out, brush up the 53rd again and come to me!" Gu Xiaodan vividly imitated Zhang Wanbang's expression and tone. As he learned, he was very sad and could no longer speak.

"This is how I don't know. I have never asked any teacher to ask questions." Xu Rui said indifferently.

"Stop, Xu Rui, come out with me." Shen Qi winked at Xu Rui and called Xu Rui to the corridor outside the classroom.

"What are you doing?" Xu Rui asked.

"In my third year of high school, people are talking about studying, but you just look careless. Don't be like this. Can you calm down and read for a few days?" Shen Qi said.

"Reading, reading is a bird for reading." Xu Rui's skin became darker and his body became stronger and stronger. He grew to 1.87 meters tall, 88 meters tall, and was almost 1.9 meters tall.

Shen Qi asked: "Then what are your plans in the future?"

"You are my dad? Why do you care about so much?"

"Okay, okay, I don't care about you, you do whatever you want. Anyway, you are so big that you can always make a fortune in the future."

"Shen Qi, you think it's amazing to study at Peking University, right? It's very awesome, right?"

"No, just let it go, let it go."

Xu Rui said contemptuously: "What's so great about Peking University? I want to study at Tsinghua University."

Shen Qi thought he had heard it wrong: "Which Tsinghua University?"

Xu Rui: "Don't pretend to be stupid. There are several Tsinghua University in China and the one next door to Peking University. You have been there and have stayed there for a few days."

"Damn, are you crazy? You can't get to Tsinghua University by paying money. Unless your family's background is super tough, you can't even pay the money. You have relatives in the capital? A high-ranking official?" Shen Qixin said, Xu Rui, you are hiding deeply, no wonder you are so careless.

"Shen Qi, what I hate most is that you are a bastard who is arrogant if you have good grades. If you weren't my brother, I would have beaten you." Xu Rui gave Shen Qi a blank look and said, "Will the whole world allow you to be recommended?"
