I just want to be a quiet scholar

Chapter 9 Learning Makes People Happy
A game of basketball made Shen Qi and Xu Rui reconcile as before, and the two drank iced Coke outside the school shop, feeling comfortable.

After returning to the classroom, Xu Rui was no longer in high spirits, the honey juice domineering disappeared, replaced by listlessness.

Shen Qi did not forget the math problems that Zhang Wanbang left him, and there are still three problems left to solve. The difficulty of these three problems is further deepened, and the concept of Frobenius matrix rank, Laplace theorem, Klein Mom's Law, and the subsequent corollaries of Fourier and Poincaré, which relate to the theoretical system of matrices of infinite order.

Although Gao Dai is abstract, it is an introductory course for the Department of Mathematics after all. Even if you cannot fully understand those abstract concepts, you can barely follow the routines by memorizing them.

Shen Qi struggled to follow the routine until 10 o'clock in the evening, and finally completed the answer to the last three questions.

The next morning, Shen Qi came to Zhang Wanbang's office and handed the answer sheet to Zhang Wanbang.

"It seems that you have encountered some obstacles." Zhang Wanbang took the answer sheet and browsed quickly, and he was not expecting that Shen Qi encountered obstacles.

"Yes, Mr. Zhang, since the matrix is ​​derived from the determinant, what is the use of the quaternion? I thought about it all night and didn't understand it. In fact, I was blind to the last three questions."

"I learned applied mathematics first and then transferred to a normal school. I didn't understand this until my sophomore year. Shen Qi, please go back to the classroom first, and come back to me at noon. In addition, I must remind you not to put all your energy on it. In mathematics, you don't want to learn Chinese? You don't want English? I'm your math teacher and your class teacher. I can tell you responsibly that the college entrance examination will not only take mathematics as a course."

"Oh okay, I know."

Shen Qi returned to the classroom, took out "Advanced Algebra" and continued to study, but he didn't listen to the Chinese class.

"I'm addicted to mathematics, I can't extricate myself, how can I break it?"

After school at noon, Shen Qi came to Zhang Wanbang's office again.

Zhang Wanbang gave him two pieces of paper, one for the review of the five questions yesterday, and the other for writing new five questions on the blank paper.

Shen Qi finished his lunch and began to study these two topics.

Yesterday's five questions, Zhang Wanbang reviewed, and left a note in the blank of the answer sheet:
"Although mathematics may appear to be nothing more than a language or tool, most of its vivid concepts can provide keys to new areas of thought."

"Determinants and matrices are completely reforms in mathematical language. Shen Qi, you must deeply understand this before you can make a difference in algebra."

"The third question, you misunderstood the Frobenius characteristic equation. Remember, the smallest polynomial is the polynomial with the lowest degree satisfied by the matrix, and it is unique."

"The fourth question, f(λ)=(λ-λ1)^k1(λ-λ2)^k2...(λ-λi)^ki, I have not witnessed your problem-solving process, but I can be sure Say, you're rigging the standard model."

"But you can get the correct answer out of the box, proving that you have two strokes. At least you know how to fumble the routine, but this routine is not the easiest routine."

"The point of mathematics is to solve the most complex problems in the simplest and most efficient way."

"Now I'll tell you the most concise routine of Ruo Erdang standard type, make J=XXXX..."

……

Zhang Wanbang's annotations on the answer sheet are the essence of what he has learned throughout his life. He uses limited space to interpret the most core mathematical ideas and skills, and he is guiding Shen Qi.

These cannot be learned from textbooks, at least not as specific, focused, and targeted as Zhang Wanbang's annotations.

Shen Qi understood in seconds, and the bottleneck that had plagued him for more than a week broke through in an instant: "So it is, so it is! Teacher Zhang's writing is all the essence, and it has benefited a lot!"

A line of text flashed in the system: "The host has been instructed by experts in the field of mathematics, and has learned new professional skills. The score of the master is +100."

"100 points! It's so hot!" Shen Qi jumped up excitedly, Mr. Zhang, you are a master, you teach me knowledge, and help me to score points. Thousands of words can be summed up in four words: Teacher's kindness is like a mountain .

Shen Qi absorbed and digested yesterday's five questions, numbered this "secret volume" as "Internal Reference 1", and put it in his schoolbag.

Next, Shen Qi began to study "Internal Reference 2", that is, the 5 questions Zhang Wanbang asked today.

Unlike other natural sciences, mathematics cannot test theoretical hypotheses with experimental equipment.

Mathematical experiments mainly rely on brain supplementation. After fully understanding and understanding various theories and concepts, proficiency is improved through derivation, proof, and assumption.

For the next two weeks, Shen Qi's daily routine was to go to Zhang Wanbang's office every morning and noon to deliver the "internal reference".

For Shen Qi, Zhang Wanbang has two identities. In the classroom, Zhang Wanbang is an ordinary math teacher, and he explains high school math knowledge points.

Outside of the classroom, Zhang Wanbang is the "skilled man" who directs Shen Qi, and he spreads deeper mathematical knowledge.

"The host listens carefully to a physics class, and the Xueba points +1."

"The host didn't listen carefully to the Chinese class, and the Xueba points +0. But the host solves a math problem in the language class, and the Xueba points +5."

"The host has performed physical exercises such as running and playing for 1 hour, and the score of Xueba is +1."

"The host has been instructed by experts in the field of mathematics, and has comprehended new professional skills. The score of the master is +100."

"The host learns "Mathematical Analysis" by himself for 3 hours, and the score of the master is +10."

……

Shen Qi's schedule is very full, and he steadily earns 120-130 Xueba points every day.

Among them, the channel with the greatest contribution is "getting expert guidance in the field of mathematics", that is, the extracurricular interaction between Shen Qi and Zhang Wanbang.

Zhang Wanbang explained high school mathematics in class, but he could no longer provide Shen Qi with even 1 point for being a master student.

However, in the more professional field of mathematics, Zhang Wanbang provided Shen Qi with 100 points per day.

Driven by the "Master-Apprentice Model", Shen Qi's mathematical combat ability has been further improved. His "Internal Reference" series has been collected in "Internal Reference 15", and the research scope has been extended to indefinite integrals, Fourier series, double-leaf rotation double Surfaces, ellipsoids, and other fields cover several branches such as advanced generation, math scores, and solution. Shen Qi is now going to take the majors exams for the first and second year of the mathematics department, and he should not fail.

April was a month of rapid progress for Shen Qi.

By April 4th, Shen Qi had accumulated 20 Xueba points: "Finally, it's time to level up again."

Mathematics Level 2 upgrades to Mathematics Level 3, which requires 3000 Xueba points.

"System, I want to upgrade, and the math indicator will be upgraded to level 3."

"After deducting 3000 Xueba points, the host's math index will be upgraded to level 3."

Levels 2 and 3 are defined as advanced levels by the system, which can be understood as primary advancement and intermediate advancement.

Host, Shen Qi

age, 17
1. Mathematics Level 3 (0/5000)

2. Sports Level 1 (0/1000)

3. Chinese Level 0 (0/100)

3. English level 0 (0/100)

3. Physics Level 0 (0/100)

3. Chemistry 0 (0/100)

3. Creature level 0 (0/100)

3. History level 0 (0/100)

3. Geography Level 0 (0/100)

3. Political level 0 (0/100)

The balance of Xueba points: 1205
The system has carried out the subject rankings. Shen Qi's mathematics index is far ahead at level 3, sports index ranks second at level 1, and the remaining eight disciplines are tied for third in level 0.

A total of 3 Xueba points are required to upgrade mathematics from level 5 to level 1.

Shen Qi earns a steady income of 100+ academic points every day, and 1 academic points can be obtained within a foreseeable time.

After all, Shen Qi would be able to accumulate 4 Xueba points in four months at the latest, and he would definitely be the first to hit level 1 in mathematics before graduating from high school.
