All-round mathematician

Chapter 116 Mathematical analysis without a clue

University life is definitely more leisurely than high school, and most of the learning depends on self-consciousness.The counselors also treat the students as adults, and if something happens, let them know in the class group, if it is really impossible, ask the class leader to speak up.

After two advanced classes, the morning class is over.There are not enough classrooms in the university, and you cannot be fixed as a class.

After class, Su Jun'an called Yang Fan, and the three returned to the dormitory.

"How about it, did Gao Dai gain anything from listening to the land?" Pan Zhe said.

There are two beds on each side of the dormitory against the wall. Originally, the two of them occupied one side, and the four desks in the middle were close together. One side was used for notebooks, and the other side was used for homework and sundries. It was just right.

Yang Fan's arrival disrupted their rhythm, but fortunately, both of them are good, so they cleared up the next chapter table for Yang Fan to use.

Pan Zhe sat down in his seat, opened the book, and prepared to review today's Gao Dai chapter.

"There are many stools, you can do whatever you want." Su Jun'an said the same.

Their hard work impresses Yang Fan, who thought they could play games and go out to fool around, but unexpectedly they did their homework.

That expression caught Pan Zhe's eyes, and he explained: "The entertainment activities are held at night, and you can't really eat and drink every day when you enter Shuimu. At least you have to get the certificate."

Mizuki's atmosphere is generally forward, and the two have to bite the bullet and keep up. Anyway, they were top students in high school, how can they be compared by others.

"I just asked you how Gao Dai is, and tell me about your experience." Pan Zhe turned to today's chapter in his book, and he just asked casually, after all, it was his first day of class.

"That's right, it's unfathomable." Yang Fan didn't tell the truth, and no one believed him when he said it, so he kept his clumsiness first. It can be said that he has no worse grasp of the line generation in Gao Dai than the two of them.

"You skipped the previous chapters, so I don't understand it a bit. In fact, the determinants of the previous things are very simple, and the rank of the matrix, linear equations, etc. will be considered as an introduction. I recently learned about vectors. It has a taste."

Su Jun'an tried to speak in a simple way, Gao Dai's subject, he and Pan Zhe both learned it well.

"Thank you two big brothers for reminding me, I will start from the beginning myself."

The dormitory was very quiet, Yang Fan read the book by himself, the other two did the questions, and sometimes exchanged a few words.

Yang Fan also understood that Gao Dai couldn't fail the two top students.At the same time, I am also happy for the atmosphere of Shuimu. This is the place for learning, mutual supervision and common progress.

At noon, after eating together, Yang Fan wandered around the campus alone, and returned to the dormitory at [-]:[-] pm.

At 1:[-], another professional course, mathematical analysis.It was the same teaching building, but with a different classroom.

A male professor with slightly white temples entered the professorship without any opening remarks. He said with a straight face: "Many students say that scores are difficult and cannot be applied in practice. They are purely formulas. Let me tell you, those who like it will not find it difficult, and those who don't like it Ask your classmates, is there no one in the class who understands it?"

"There are a few classmates who always want to go wrong. Before the end of the semester, they come to me to burn incense and complain. Your high school is all top-notch. Don't you want to be inferior to the classmates next to you?"

"Professor Tang, it's really difficult."

"The course is too fast, and the lecture is too deep, and everyone can't keep up."

"En..." The professor pondered for a while, and the students begged him in a roundabout way, so they must be comforted, and finally decided to give some hints, saying, "It's true that at the end of the semester, I will brush some of Jimedovich's question bank, understand?"

"Professor, everyone is too late for five thousand questions."

"That's right, you don't need to take other courses, just do the questions."

"In this case..." The professor was still young and easy to talk, and he held his chin and pondered for a while, "I think the second quarter of the second book is good. What do you think?"

For the final score exam, the professor in front of me will give the papers.

This reminder was very powerful, and the morale of the students in the audience was greatly boosted, saying: "Okay."

When it comes to the actual exam, the questions will not be set invariably, there will definitely be a turn in thinking, and some other questions will be added, just pass it on the surface.

Yang Fan was dumbfounded, no wonder others said that the university is a mess, so there are so many famous schools.Those who are easy to talk will pass with their eyes closed, and there will be burning incense in advance and so on.

"Okay, let's continue the lecture. In this section, let's learn about abnormal integrals. Abnormal integrals are also called generalized integrals. They are extensions of ordinary definite integrals. They refer to integrals with infinite upper and lower limits, or integrals with flaws. The former is called the infinite generalized integral, and the latter is called the flawed integral..."

Yang Fan immediately searched the table of contents, turned to that chapter, pricked up his ears, combined with the teaching materials, and tried not to miss any teaching.

After listening for a full 20 minutes, I was at a loss, and the system did not prompt.

Professional courses are taught in two consecutive sessions, with a 10-minute break in between.

"Because the generalized integral of an unbounded function on a finite interval is often confused with the normal integral, when calculating the integral, one should first judge that there are flawless points on the integral interval..."

Lectures are still going on, and sometimes the professor will call the students to answer questions as they did in high school.

In less than 2 hours, Yang Fan still had no clue.

"What's going on, can't you speed up by listening to the lecture? Why isn't the system responding?"

It was a slap in the face, which stunned Yang Fan.At the end of the course, he was still thinking on the way: "Is it because there is no foundation, so listening is useless? If you regard teaching as a kind of review, then it makes sense."

"It seems that you still need to improve your proficiency to a certain level first, and form a concept of this course, and then teaching can be considered as a help. Only when you are strong yourself can you be really strong."

Back at the dormitory, Pan Zhe saw that Yang Fan’s complexion was pale, and advised him, “Don’t worry, you should study by yourself for a while, at least you are one step ahead of us, and you have half a year’s advantage. You can still study in Shuimu next year.” Bully."

"Yeah Fan, your teacher is just to open your eyes. If you really want to learn, you won't jump in the queue. There is no foundation, and it is not step-by-step. Of course, it is very difficult."

Su Jun'an patted Yang Fan on the shoulder, pushed the latter to the seat, and said, "My computer is on, play some games and relax."

The two of them had good intentions, Yang Fan did not fail to understand, figured out what the problem was, and said, "All right, let me read the news."

The two of them spread out the books as they did in the morning, and counting points was very difficult for them.

"Old Tang is good, but if you really believe him, you will die. He can't bear too much criticism. I estimate that Jimedovich will score about 30 points in the final question, and we will have another [-] points. Take it yourself." Su Jun'an, who is rough and bold, has a bold mind, and he has been in the mathematics circle, and he is very sensitive.

"This is reasonable, so we still can't relax. Come according to the original plan."

Pan Zhe agreed, and the reminder belongs to the reminder. It is not a pheasant school, so how could it be possible to send points directly.

Pointing at the textbook in front of him, he cursed: "We are still using Chen Jixiu's version, and colleges and universities with a bit of brains have started to use Shi Jihuai's textbook. What do the heads of the math school think?"

"There's no way. After changing, some people will think that something is wrong. Most colleges still use East China Normal University and Chen Jixiu, so just let it go."

Su Junan is also full of anger, the textbooks are not good, and it is difficult to learn by himself, so ask the professor, do you think it is high school?People don't have time, unless they burn incense for a long time.
