In the end, reason still prevailed over greed, and Lu Zhou dispelled this unrealistic idea.

A freshman student publishes sci itself is nothing, anyway, the phenomenon of irrigation of those math sci journals in China is quite serious, as long as your English skills are OK, and the irrigation is like that, maybe you will pass.

This phenomenon of indiscriminate filling is so that a certain good deed has made a list of several well-known irrigation journals in China. At the top of the list, Applied-Mathematics & Computation (AMC), is well known in the field of irrigation.

Speaking of Shanghai University alone, in just four years, hundreds of mathematics papers have been published on AMC, and some irrigators fill more than 20 papers a year, which is not a problem at all!

In order to ensure the academic quality of the papers, those established journals with discipline often strictly control the number of papers published in a year to less than 100. However, this "Big Mac journal" is very skinny, publishing more than 1,000 papers a year, coupled with cross-citations and other phenomena, the impact factor is jumping up! Even due to the existence of a large number of pseudo-reviewers, a certain editorial board member posted more than 100 articles on it!

Lu Zhou may not be confident in other SCI journals, but AMC's words ......

It's okay to say he's confident, it's okay to say he's inflated.

In short, Lu Zhou felt that it was not a big problem.

However, if the proof of Zhou's conjecture is published in a SCI journal, then it will be a big problem. It's not a question of whether he can pass or not, it's definitely okay to pass, but the key is whether he can hold it after he passes.

In the end, although Lu Zhou still chose the third task, he was not going to use Zhou's conjecture proof, but wrote a random irrigation paper to pass the task.

With his current understanding of advanced mathematics and mathematical analysis, he is no less than a graduate student. Coupled with the fourth-level English, the difference between writing an English paper and writing an English paper is only some professional terms, and these can be solved by looking up a dictionary.

On the other hand, looking at the other two tasks, the first one is that he doesn't have that connection, and he doesn't think he has such a high emotional intelligence.

The second one, I haven't opened the big things course in my freshman year, but I'm afraid that the system brushes out all the high school physics exercises, and the ghost knows how many points the difficulty coefficient is determined. And the physics level is not so attractive to him, and the name is only used in the late stage when he hears it, and it is not too late to practice when he needs to.

After choosing the task, Lu Zhou patted his ass. The grass clippings on the strands stood up and walked in the direction of the dormitory humming a song.

After delaying outside for so long, if you don't go back, I'm afraid that Liu Rui will go insane.

This kid is very weird, although he is usually very generous, but only in terms of learning, he is so careful that people are speechless. A glance at a note can chase you two streets, and a question can throw you a dozen rolls of the eyes, which is probably the kind of person you are talking about. In his eyes, it seems that the whole world is full of his competitors, and what he is chasing is probably not an academic height, but just the first place in the eyes of teachers or classmates, or the status of "academic tyrant".

Is this kind of person considered a top student?

Lu Zhou doesn't think so.

In the eyes of Zhenxueba, all mortals are scum, what if I showed you my notes? Did Zhou guess you would? You can't figure it out in front of you!

In Lu Zhou's cognition, there seems to be only one person who meets the conditions of a scholar.

Well, that's right.

There is no doubt that he is talking about himself.

……

Push open the door to the dormitory, no more, no less, exactly ten o'clock.

Liu Rui was holding the exercise book and brushing the questions, and the other two people were not in the dormitory, probably playing cards next door. Shi Shang is a person who usually listens to lectures and doesn't take much time to review at the end of the term. As for Huang Guangming, he is probably the legendary god of learning, who usually doesn't listen to lectures, hugging Buddha's feet before the exam, but the kind with high scores is not like words.

Throwing the backpack on the table, Lu Zhou reached into the drawer to find his bath card.

At this time, Liu Rui put down the exercise book in his hand and glanced at the direction of Lu Zhou and asked.

"Elbow, so hard?"

"I have to work hard, I haven't touched a book for almost half a semester, and if I don't work hard, it's too late." Throwing the bath towel over his shoulder, Lu Zhou stood up from his chair.

Seeing that Lu Zhou was going to take a bath, Liu Rui suddenly said, "I can't do the problem here, can you help me take a look?" ”

Yo, it's weird.

And the questions you can't get over?

"Let's take a look."

Lu Zhou stretched out his hand, Liu Rui pushed his glasses, handed over the workbook in his hand, pointed to the topic that was circled and said, "This is it." ”

"Points problem? This thing shouldn't be difficult, right......" The question swept twice, and unexpectedly the type of question that he had never seen, Lu Zhou was interested, and he was not in a hurry to take a bath, so he sat back on the chair with the exercise book, picked up the pen and began to write and draw on the scratch paper.

If he could stump Liu Rui's question before, he would definitely not be able to solve it. I don't know why, but at this moment, he doesn't have the slightest idea of "impossible" in his heart.

Watching Lu Zhou take the pen and calculate for a while, Liu Rui breathed a sigh of relief in his heart, and secretly despised the sentence in his heart, he was really a scumbag, no matter how he pretended to be, he was a scumbag.

Regarding this question, it is true that he can't solve it, but in fact, there is a reference answer, and there is a detailed solution to the answer. The reason why I asked Lu Zhou this question was not because he was humbly seeking advice, but just because he wanted to "spy on the enemy's situation".

Take 10,000 steps back, even if he wants to ask a math problem, he won't look for Lu Zhou, a scumbag.

Thinking so, Liu Rui said: "Why don't you copy the question down and do it?" I'm going to figure out the next question first? ”

The subconscious implication is that you can't write anyway, so I won't waste your time.

However, Lu Zhou's reaction was beyond Liu Rui's expectations.

“…… No, unraveled. ”

Solution, solution?!

Liu Rui's eyes widened, and his eyes were about to bulge out in surprise.

"Well, you heard it right." Turning the ballpoint pen in his hand, Lu Zhou explained to the formula on the scratch paper, "A typical double integration problem, the first step is to convert the Cartesian coordinates into polar coordinates and start the operation, due to the symmetry of the intervals, this part of the formula can be reduced to cotx² after calculation......"

"Finally, it will be converted into CSCx² points! Then substitute the original function! Liu Rui's pupils contracted slightly, and he keenly saw through the core idea of this solution, and the next steps were like pushing a boat down the river, just keep counting down, without any difficulty.

Damn, I didn't think of that......

"Bingo! That's right. Lu Zhou smiled and nodded, and said in his heart that the children could be taught.

"Thank you...... The scratch paper was borrowed from me, and I took it to study it. ”

"Take it, you're welcome!" Lu Zhou waved his hand generously, stood up, and walked towards the bathroom.

Taking Lu Zhou's scratch paper back to his seat, Liu Rui pushed his glasses and stared at the topic, his brows furrowed slightly, and he fell into deep thought.

Although the solution is novel, the solution process is clearly written, and the knowledge points involved are not beyond the outline, even if there is no explanation from Lu Zhou, he can easily understand it.

It's just that he can't figure it out, how did that guy Lu Zhou come up with it?

And in such a short period of time......

Have you done this kind of question before?

Liu Rui thought about it, and it seemed that there was only this possibility. Otherwise, he really couldn't imagine that this scumbag, who was busy working part-time all day long, would crush him, a recognized class of scholars, in solving problems.

Flipping to the back of the exercise book, Liu Rui looked at the solution of the answer, and the whole person was stunned for a moment and muttered to himself.

"Impossible......"

The answer is exactly right...... But that's not the point.

The point is that Lu Zhou's solution is even simpler than the solution of the standard answer! The answer does not take into account the solution of converting Cartesian coordinates to polar coordinates, but directly applies the formula to the quadratic splitting of the integrals, which makes the computation seem unusually large.

And this is one of the solutions he has considered......

How is this possible!

Liu Rui bit his lip.

Suddenly I felt a little suspicious of life.
