Chapter 12 Jealousy Separates My Walls

Time passed day by day, and the high number 2 exam came as scheduled.

"Please turn off your mobile phones, and put your student ID card and ID card in the upper left corner of the desk. I re-emphasize the discipline of the exam room. Once someone is found cheating, they will not tolerate it and send it to the Academic Affairs Office. The students will be promoted soon. I’m a sophomore in my sophomore year, I hope you don’t have this kind of principled problem at this juncture. There are one or two people who don’t believe in evil at this time of year. I hope you can help me to abide by the discipline.”

The old professor who did not know stood on the podium and glanced down, then raised his chin at the graduate student next to him, "Xiao Wang, you start from the right."

"Okay." The man named Xiao Wang nodded and started to check the students' documents from the right.

The old professor put the thermos on the lecture table and started to check from the left.

Lu Zhou stretched his waist, turned off the phone, stuffed it into his backpack, and put the reference books and electronic devices on the desk in the first row like everyone else.

Finally the day has come!

After the exam week, there is a lot of time to do your own business.

After returning to his seat and sitting down, Lu Zhou showed his ID card and student ID card to the graduate student, then sat in a daze, waiting for his hair to curl.

After all, it is a famous 985 school, and Jinda's examination style and discipline are still quite strict.

Don't look at the old man wearing reading glasses with a kind smile on his face. But if you dare to flip down the note or look at your phone, no matter how well you hide it, he will be able to find it out for you at a glance.

A few classmates who had already prepared cheat sheets, sat there fidgeting with pale faces, wanting to copy but not daring to do it.

Lu Zhou sighed in his heart, and mourned for these unfortunate children, and then wrote quickly.

I heard that the paper was written by Lao Tang, but no matter who the person who wrote the test is, the knowledge points examined in this final exam cannot exceed the scope of the syllabus. At least from Lu Zhou's point of view, the above question is easy.

The first category is to fill in the blanks. The first problem is to find the general solution of the differential equation. It is enough to calculate it directly according to the routine. Although the formula is a bit complicated, it can never be changed.

The second question is to find the equation of a straight line parallel to a certain line through the space coordinate point. There is nothing to say, and it is also a sub-question.

The third question is for derivation, and the fourth question is for curve integral, and points are given.

The fifth question is very interesting. Through the known f(x)=... equation, and the Fourier sine series expansion and function of f(x) with 3/2π as the period is S(x), find S(x) (-5/2π) value.

emmm...

Slightly difficult.

The pen he was holding lightly tapped three times on the scratch paper, but Lu Zhou quickly solved the answer.

This question seems to be a bit complicated, especially when examining the relevant knowledge points of Fourier sine series, and jointly examining the product of equations, the partial equation is not very simple. However, once you figure out how to understand the method, the seemingly complicated calculation process is actually not that difficult, and it is a matter of smooth sailing.

At least for Lu Zhou, who has already read through two textbooks.

Immediately afterwards, he looked at the multiple-choice questions, all of which were bonus points, and he tickled the answer.

The next step is the big topic, and it's time to start the real thing!

Lu Zhou was gearing up, warmed up, and was about to start work. However, when I saw the title, I was dumbfounded...

Not because it's too difficult.

but because of...

hmmmm...

To this extent?

Lu Zhou glanced to the side secretly, only to see the buddy next door biting the cap with a frown.

Looking back, the more creative one even folded a dice with scratch paper, and even used a metaphysical problem-solving method.

At this time, a buddy stood up, walked to the podium, put down the papers, and went out the door in a dashing manner.

Lu Zhou was in awe.

Heroes see the same thing!

Sure enough, I'm not the only one who thinks this test paper is too easy!

Thinking of this, Lu Zhou no longer hesitated, began to write, and solved the problems on the paper. Except for the last question, which took five minutes, the remaining questions were basically completed within two minutes.

Picking up the test paper and looking at it, making sure there was nothing missing, Lu Zhou then glanced at the draft paper that was not even a quarter of the time, packed up, stood up, and went up to hand in the paper.

The old professor sitting next to the lecture table was drinking tea and paid no attention to Lu Zhou who came up to hand in the papers.

But the moment he saw the paper from the corner of his eye, his eyes suddenly narrowed.

Yo.

Is it full?

It's only been half an hour? !

With a light sigh, he reached out and picked up the paper, pushed the glasses on the bridge of his nose, and stared at the answers behind the questions and reviewed them line by line.

The first question is correct.

The second question is correct.

Question three...

The more he looked down, the more solemn and serious his expression became.

Although the graduate student standing next to him was curious about what was written on the paper, but seeing the serious expression on the old professor's face, he finally gave up the idea of ​​leaning over. He silently walked off the podium and patrolled the back row of the classroom.

Time passed by, and when he saw the last line of the last question, Lu Fangping's frown instantly relaxed, and he nodded approvingly.

interesting.

So interesting.

"It seems that Lao Tang has taught a good seedling..." With a sigh in his heart, Professor Lu Fangping unscrewed the teacup and took a sip, but the expression on his face was expressionless.

As for the two students who left early, the other students in the examination room didn't make any movement. At most, they only sighed in their hearts and comforted themselves: These two have already given up treatment, and I am not the only one who finds it difficult...

Except for Liu Rui, who was sitting behind Lu Zhou.

He saw with his own eyes that Lu Zhou filled the entire paper.

Although I didn't see exactly what Lu Zhou wrote on the paper, the neat answer format didn't seem like it was written randomly...

……perhaps?

Looking at my paper, I was still racking my brains on the last question of the fill-in-the-blank question, but couldn't come up with a clue.

It stands to reason that this kind of question that cannot be thought of should be given up, and it is only after writing the question that can be done that you can come back to write it. But when he thought that even Lu Zhou could do it, Liu Rui couldn't hold his breath.

Jealousy separates my walls.

Jealousy makes me factor.

ah ah ah...

Mind exploded!

Liu Rui grabbed his hair, only to feel that the whole person was not well.

...

After coming out of the examination room, Lu Zhou didn't hang out outside. He first went back to the dormitory, copied the paper into a USB flash drive, and then went to the laboratory building to find Professor Tang's office.

The office was very quiet. Apart from Professor Tang smoking by the window, there were only two seniors who were focused on the project in front of the computer, so that Lu Zhou didn't even lift his eyelids when he came in, as if he didn't even lift his eyelids. I did not notice.

Noticing Lu Zhou standing at the door, Professor Tang motioned him to come in with his eyes, saw the USB flash drive in his hand, and said with a smile, "Yo, your paper is ready so soon?"

Lu Zhou smiled politely and said, "Well, it's finally finished. Both the Chinese and English versions are in it. Can you help me read it?"

"Bring it here, isn't that what you're here for?"

Taking the USB flash drive from Lu Zhou, Professor Tang walked to the desk, opened the laptop, plugged it in, and read the paper.

"How was the exam?"

"It's alright...I don't think the problem is difficult."

"Oh, the tone is not small, I will change your paper myself."

"Teacher show mercy!"

"Don't even think about it, kid."

Tang Zhiwei smiled and opened the paper. He would only feel disgusted if someone told him this kind of plea. But when Lu Zhou said this to him, he didn't feel that something was wrong at all, he just thought it was a joke.

He knew the level of the students he taught, and asking this kid Lu Zhou to do the kind of papers that follow the syllabus is indeed a bit of a condescending talent.

The stage of this kind of student is destined not to be in the final exam of the university, but in the "Challenge Cup" college students' extracurricular academic scientific and technological works competition, or national competitions such as the National College Students Mathematical Contest in Modeling.

Focusing on the paper, Tang Zhiwei put on his glasses and looked down along the abstract of the paper.

To be honest, when Lu Zhou walked into his office with the composition, his heart was full of surprise.

For learning, it is like carrying a wooden barrel and transporting water from the sea to the reservoir.

Along the way, bumpy, trembling, conscientious... Over the mountains and mountains, through the wind and the sun, and finally came to the front of the large academic reservoir, I can pour a drop of water into the reservoir from the overturned wooden barrel, Then this journey is not a waste of time.

Those who want to become academics must first have a pious heart. Those who are eager for quick success are doomed to fail.

An undergraduate student, even if he is talented in mathematics, how much water can he carry in a bucket?

Not to mention reaching the big academic reservoir, I'm afraid I can't even get out half a mile, and that little water will evaporate on the way.

Therefore, Professor Tang Zhiwei's mood is very calm. When reading the paper, it is not the mentality of a mathematician, but the mentality of an educator, caring for a flower that has just emerged from the soil.

Even before he started to read it, he was already thinking about how to get Lu Zhou to take this paper back and redo it in a relatively gentle way. It not only taught him not to be too ambitious in his studies, but also prevented him from becoming depressed and losing confidence and interest...

However, at this moment, Professor Tang was suddenly stunned, then frowned and fell into thought.

This……

Is this really a dissertation written by an undergraduate student?

Wasn't it copied from a reference book?

Thinking of this, Professor Tang, with suspicion, took a random paragraph and posted it on Baidu to search.

No match.

If you don't believe in evil, this old gentleman has posted another paper review website, and this time he has uploaded the entire paper...

Looking at the search results, his eyes stared at the boss.

how is this possible! ?
