Chapter 72 The First Month Quiz

Full marks.

This was the real math question in the National Central University's self-enrollment exam last year, and Yu Hua actually got a perfect score.

No one knew better than Lin Wan the weight of this full-mark test paper. The math test paper at the end of last semester was only about [-]% as difficult as the real test paper.

"It turns out that you've been hiding yourself. It's kind of interesting. I don't know what your grades will be in the first month's quiz..." Lin Wan looked at the neat and beautiful exam paper, whispered to herself, and took a deep breath. , cheered up, picked up the real test paper and returned to his seat, put the prepared English test paper aside, and gave priority to learning the essence of knowledge contained in this test paper.

As a top scholar, she is very aware of the true value of this full-mark test paper, and she needs to learn the problem-solving ideas in it, so as to improve the deficiencies in the field of arithmetic.

In Peiping No. [-] Middle School, Zhao Anyuan scored first in math, and Lin Wan scored second in math. However, from today on, Yu Hua is the real No. [-] math in Peking No. [-] Middle School in Lin Wan's heart.

Tomorrow is the first month's quiz at No. [-] Middle School. Lin Wan is very curious about what level Yu Hua's grades will be.

The reading room on the second floor gradually became silent.

……

"I have read all the domestic and foreign mathematics textbooks for high school, and now I have thoroughly mastered all the elementary mathematics knowledge points such as functions, derivatives, trigonometric functions and number sequences. According to the current mathematics level and foundation, it is time to learn advanced mathematics. For self-learning advanced mathematics, L'Hubida's Law and Lagrange's Mean Value Theorem are good starting points, and then transition from derivatives and definite integrals to calculus, which is the foundation of advanced mathematics and must be mastered well."

After changing into casual clothes, Yu Hua left the school and walked on the way to Huangchenggen Bookstore. He was already perfect in elementary mathematics. He silently pondered the problem of the learning path in his mind, and studied the entry point of self-learning advanced mathematics.

It is Yu Hua's long-standing habit of doing things after planning.

Advanced mathematics is based on calculus, with deep-level algebra and geometry as the extension framework. The three intersect with each other to form the whole of advanced mathematics knowledge. It belongs to the foundation of mathematical research. The main content involves calculus, spatial analytic geometry and linearity. Algebra, series, ordinary differential equations.

This is the definition of advanced university mathematics in later generations. In this era, the concept of advanced mathematics has not yet been formed in a real sense. The mathematical knowledge that engineering universities need to learn is mainly based on calculus, deep-level algebra and geometry. Not too involved.

As we all know, all engineering students in later generations have experienced whole-body massage of high mathematics, especially the intimate greetings of calculus.

If you want to do mathematical research, advanced numbers are the foundation, and the foundation of advanced numbers is well-deserved calculus.

For Yu Hua, who wants to study in-depth in the field of mathematics, calculus is the first and most important difficulty on the road of self-learning advanced mathematics.

Going through the calculus, so far, the high number avenue has been smooth all the way.

If you can't get past the calculus, the high number road is bumpy step by step, and there are obstacles everywhere.

The entry point for self-learning advanced mathematics has been thought out, but Yu Hua still has to face a more embarrassing problem, that is, the lack of advanced mathematics teaching materials.

Well, it's still a textbook issue.

Yu Hua needs an advanced mathematics textbook as a reference. Although the omnipotent station B has a lot of content about advanced mathematics learning, but in his previous life, he has always liked to read the video materials of various female teachers, plus the rooted alliance and the ghost animal area. I haven't seen any serious academic information videos.

And the per capita 985 Zhihu, Yu Hua after the college entrance examination, has been addicted to 'Thank you, I am in the United States, just got off the plane. In the opening chapter of 'I can't extricate myself, where do I still have the mind to study high numbers.

As for the bar...

Is Tieba a place to learn advanced mathematics?

The old buddies are very nice, and Yu Hua's favorite shopping is Guevara.

After the college entrance examination, he completely let himself go, which made Yu Hua very embarrassed now. It is difficult for a clever woman to cook without rice. There is no advanced mathematics textbook containing systematic knowledge, so he taught himself a fart.

The advanced mathematics textbooks that can be bought in any Taobao store in later generations are absolutely scarce and precious books in this era. Mathematical readings and textbooks for advanced mathematics.

It's amazing.

Also very...real.

In this era, are there any advanced mathematics textbooks?
Have.

However, the situation is rather special.

According to my memory, in the field of teaching materials, the Chinese education field in this period has been in a very backward and closed state, especially arithmetic, that is, there is no standard Chinese-English version of advanced mathematics textbooks, and there is no national unified mathematics textbook. There are also some high-quality textbooks in Chinese-English versions at the level to temper students' mathematics level, so the mathematics textbooks at the university level are very embarrassing.

None of the domestic university mathematics textbooks are in Chinese, all of them are foreign originals, using American university textbooks.

Like the widely circulated Tongji Advanced Mathematics, Tao Zhexuan's real analysis, and Mr. Hua Luogeng's introduction to advanced mathematics, there are none.

Regardless of the sadness and far-reaching influence of the original foreign editions of Chung Hwa University textbooks, those things are too far away from Yu Hua. In the current situation, the original Western editions often mean scarcity and expensiveness, and there are not many theoretical acquisition channels, as Yu Hua can think of. There are probably three channels. First, buy textbooks through college students, second, go to the black market to find old books, and third, pirated books.

"First go to Huangchenggen Bookstore and ask, then look for it yourself, or you can rely on relationships to find books. If you really don't have it, then wait until the end of the quiz and go to Mr. Hua Luogeng." Yu Hua rubbed the slightly bloated On the forehead, I regretted the time when I had been researching teacher materials at station B after the college entrance examination. If I had flipped over a brand that explained Tongji Advanced Mathematics, why would I have to worry about the advanced mathematics textbooks now.

However, the headache returned to the headache, which only caused a little trouble to Yu Hua, and Yu Hua did not panic.

Can't buy textbooks, can't find old books, it's no big deal, Hua Luogeng who just came back from abroad must have.

By the end of the quiz at the end of the month, Yu Hua would have the confidence to take the math report card and go to Tsinghua Western Academy to find Hua Luogeng. All problems will be solved by then.

In terms of mathematics, in this era, no one can compare to Hua Luogeng.

As for when the quiz at the end of the month will come, um...it will be tomorrow.

In February 1937, there were only 2 days, today is the last day, tomorrow is March.

By convention, Peking No. [-] Middle School holds a school-wide quiz on the first day of every month to check students' learning level.

After thinking about the field of study, Yu Hua stopped thinking about it and concentrated on his journey.

The whole person shuttled through the narrow alley in the north of the city, and finally reached the destination after half an hour.
