Time passed day by day, and the high math 2 exam arrived as scheduled.

"Please turn off your mobile phones and put your student ID and ID cards in the upper left corner of your desk. Once again, I emphasize the discipline of the examination room, once someone is found to be cheating, I will not tolerate it and send it to the Academic Affairs Office for processing. The students are about to enter their sophomore year, and I hope that this kind of principled question will not be raised at this juncture. At this time of year there are one or two unbelievers who want you to help them be disciplined. ”

The old professor he didn't know stood on the podium and looked down twice, and then raised his chin to the graduate student next to him, "Xiao Wang, you start from the right." ”

"Okay." The man, Xiao Wang, nodded, and began to check the student's documents from the right.

The old professor placed the thermos flask on the lectern and checked it from the left.

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

It's finally the day!

After exam week, there's plenty of time to do your own business.

Returning to his place and sitting down, Lu Zhou showed his ID card and student ID card to the graduate student, and then sat in a daze, waiting for the roll to be issued.

After all, it is a 985 school, and the examination style and discipline of Jinda are still quite strict.

Don't look at the old man wearing reading glasses and 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 can find it out for you at a glance.

There were a few classmates who had already done a good job of cheat sheets, and they sat there restlessly with pale faces, wanting to copy but not daring to do it.

Lu Zhou sighed in his heart, mourned silently for these unlucky children, and then wrote hard.

I heard that the paper was written by Lao Tang, but no matter who the question is, it is impossible for the knowledge points examined in this final exam to be beyond the scope of the syllabus. At least in Lu Zhou's opinion, the above topic is easy.

The first category is to fill in the blanks, the first problem is to find the general solution of differential equations, just calculate it directly according to the routine, although the formula is a little complicated, but it can be changed from its origin, in Lu Zhou's view, it is a sub-problem.

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

The third question is for derivation, and the fourth question is for the integration of curves, and points are given.

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

emmm……

It's a little bit more difficult.

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

This problem seems to be a bit complicated, especially when examining the knowledge points related to Fourier sine series, and jointly examining the equation to find the product, the partial equation is not very simple. However, once you figure out the method, the seemingly complicated calculation process is actually not that difficult, and it is all a matter of pushing the boat along the water.

At least for Lu Zhou, who has already thoroughly eaten two textbooks.

Immediately after, he looked at the multiple-choice questions, which were also some points, and he ticked the answers by brushing.

Then there's the big question, and it's time to get to the real thing!

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

It's not that it's too hard.

It's because ......

emmmm……

Is that the degree?

Lu Zhou secretly glanced to the side, and saw that the buddy next door was biting the pen cover with a sad face.

Looking further back, the more creative one actually folded a dice with scratch paper, and actually used the metaphysical method to solve the problem.

At this time, a buddy stood up, walked to the podium, put down the volume, and went out in style.

Lu Zhou was in awe.

Heroes see the same thing!

Sure enough, I am not the only one who thinks this test paper is too simple!

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

Picked up the test paper and looked at it to make sure that there was no omission, Lu Zhou then looked at the scratch paper that had not yet been written a quarter, packed up his things, stood up, and went up to hand in the paper.

The old professor sitting at the lectern was drinking tea and didn't pay any attention to Lu Zhou, who came up to hand in the papers.

But the moment he saw the scroll with his peripheral vision, his eyes suddenly narrowed.

Yo.

It's all over?

It's only been half an hour?!

With a soft sigh, he reached out and picked up the paper, pushed the glasses on the bridge of his nose, and stared at the answers at the back of the question to review them line by line.

The first question is correct.

Question 2 is correct.

Question 3......

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, he saw the serious expression on the old professor's face, and finally dispelled the idea of getting over. Silently stepped off the podium and patrolled to the back of the classroom.

Time passed minute by minute, and when he saw the last line of the last question, Lu Fangping's frowning brows instantly stretched out, and he nodded slightly approvingly.

Interesting.

It's so interesting.

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

For the two students who left the room early, the other students in the examination room didn't move, at most they just sighed in their hearts, and comforted themselves: These are already two people who have 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 had filled the entire volume.

Although I didn't see what Lu Zhou wrote on the paper, the neat format of the answer obviously didn't look like it was written out of order......

…… Probably?

Looking at his paper, he was still racking his brains on the last question of the fill-in-the-blank question, and he couldn't think of a clue at all.

It stands to reason that if you can't think of this kind of question, you should give up and wait until you finish writing the question you know how to do. But when he thought that even Lu Zhou could do it, Liu Rui's heart couldn't swallow this breath.

Jealousy separates my walls.

Jealousy factored me.

Ahh......hhh

The mentality exploded!

Liu Rui grabbed his hair, only feeling that the whole person was not good.

……

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

The office was very quiet, except for Professor Tang standing by the window and smoking, only the two seniors were busy with the project at hand in front of the computer, so much so that Lu Zhou didn't even raise his eyelids when he came in, as if he hadn't noticed it at all.

Noticing Lu Zhou standing at the door, Professor Tang motioned for him to come in with his eyes, and when he saw the USB flash drive in his hand, he smiled and said, "Yo, your thesis was done so quickly?" ”

Lu Zhou smiled politely and said, "Well, it's finally finished, the Chinese version and the English version are in it, can you please help me take a look?" ”

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

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

"How's the exam?"

"Okay...... I don't think the topic is difficult. ”

"Heh, the tone is not small, I will change your roll myself."

"Teacher's mercy!"

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

Tang Zhiwei smiled and opened the paper. If someone told him to intercede like this, he would only feel disgusted. But when Lu Zhou said this to him, he didn't feel anything wrong at all, he just laughed.

He knew what level the students he taught, and it was indeed a bit condescending to let Lu Zhou, a kid, do the kind of papers that were made according to the syllabus.

This kind of student's stage is destined not to be in the final exam of the university, but in the "Challenge Cup" college students' extracurricular academic science and technology work competition, or the national competition of college students' mathematical modeling competition.

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

In fact, to be honest, when Lu Zhou walked into his office with an essay, his heart was full of surprise.

Doing scholarship is like carrying a wooden barrel and carrying water from the sea to a reservoir.

Along the way, there were bumps, trembling, and conscientiousness...... After crossing the mountains and mountains, flowing through the wind and sun, and finally walking in front of the big academic reservoir, you can pour a drop of water into the reservoir from the turned over wooden barrel, then this road is not a wasted journey.

If you want to become an academic, you must first have a pious heart. People who are anxious for quick success are doomed to fail.

An undergraduate, no matter how talented he is in mathematics, can he hold a bucket of water?

Not to mention arriving at the big reservoir of academics, I am afraid that I will not be able to walk even half a mile, and that little bit of water will be steamed dry on the road.

Therefore, Professor Tang Zhiwei's mood is very calm, and when he reads the paper, he is not a mathematician's mentality, but an educator's mentality, caring for a flower that has just emerged from the soil.

Even before he started reading 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 to prevent him from becoming depressed and losing confidence and interest......

However, at this moment, Professor Tang was suddenly stunned, and then his brows furrowed, and he fell into thought.

This......

Is this really a paper written by an undergraduate?

It can't be copied from some reference book, right?

Thinking of this, Professor Tang took a random screenshot with the intention of doubting the letter, and pasted it on the whiteness to search.

There is no match.

Don't believe in evil, this old gentleman has posted another paper plagiarism check website, and this time the entire paper has been uploaded......

Looking at the search results, his eyes widened.

How can it be!?
