After just two days of relaxation, Zhang Yu gathered his good mood and devoted himself wholeheartedly to studying.
After having children, Zhang Yu must study harder in order to support his children.
In addition to normal classes, Zhang Yu basically spends time in the library. The seat by the window directly becomes a VIP seat, exclusive to Zhang Yu.
The two deans also changed their teaching ideas. Unless there is a problem that Zhang Yu cannot solve, they will not easily help Zhang Yu explain the question types.
This is also a kind of training for Zhang Yu. I hope Zhang Yu will develop the habit of self-study.
For Zhang Yu, in fact, not much has changed. The time he spent studying with the two teachers was not long. Most of the time Zhang Yu studied by himself in the library.
However, Dean Zhao told Zhang Yu not to forget his main job. As a student of the Department of Mechanical Engineering, his learning progress and level must be on par with or higher than that of mathematics.
Yes, mathematics is indeed of great help to machinery, but the essence of learning mathematics is to serve machinery manufacturing and cannot put the cart before the horse.
Whether it is mathematics, physics, or materials, they are all the basis of mechanical manufacturing. In other words, mechanical manufacturing turns the theories of the three subjects into reality.
Zhang Yu also felt that what Teacher Zhao said was correct. Zhang Yu temporarily sealed the mathematics book and found the 60th edition of "Mechanical Parts" from the library bookshelf.
Compared with mathematics, Zhang Yu's accumulation of mechanical knowledge is much deeper than mathematics.
Coupled with the usual class attendance and the guidance of professional teachers, the mechanical skill bar directly exceeded level three.
Zhang Yu also read the book "Mechanical Parts" in his previous life, but it was not the 60th edition, but the 06th edition.
Compared with the 2006 version of "Mechanical Parts", the 60 version is too barren, and Zhang Yu has not seen many knowledge points.
But even so, Zhang Yu is very satisfied, and some studies are good.
I only remember the name of the book from what I read in my previous life. As for the content, I have forgotten about 70% of it.
Time passes day by day, and knowledge is accumulated rapidly.
Occasionally there will be questions that I can't solve, so I'll check in with two teachers. Most of the remaining time will be given to the library and the other half to normal classes.
The classmates in the class also gradually became alienated from Zhang Yu. This was not because the students were deliberately alienated, but because of time issues, Zhang Yu had very little interaction with his classmates.
The classmates in the class only know that there is Zhang Yu in the class. Apart from knowing that Zhang Yu loves to study, they know nothing else.
As for Gao Minglin and others, their attitude towards Zhang Yu gradually changed from uneasy to calm.
The four-person dormitory formed two distinct small groups, Zhang Yu and his three roommates.
……
"Students, time flies so fast. Congratulations to everyone on your first mock exam."
"It's a mule or a horse, let's pull it out and run around, okay!"
"Ah~!"
Li Ziqiang never mentioned this exam at all. The students were caught off guard by this sudden attack.
"Bang bang bang!"
"Hey, hey, hey! What are you doing? What are you doing!"
"What's the sound like? What's going on? Are you having a hard time taking the exam?"
"More than half of this semester has passed. Don't tell me that you haven't studied hard. Let me tell you, the exam is a summary of your study during this period. I want to see if you have done it. So settle down and study hard." p>
The instructor Li Ziqiang gave a simple speech and gave up the classroom to mathematics professor Lu Pingfang.
Lu Pingfang did not say much and directly asked his graduate students to distribute the papers to the students.
When the students saw that the first subject was mathematics, they had one head and two heads, but now they can only bite the bullet.
Lu Pingfang looked at the students below and smiled softly.
This time, the mock test was set by Dean Wang himself. On the way here, Lu Pingfang had read these test questions.
At this level of difficulty, it is a difficult ordeal for students in the Department of Mathematics.
Not to mention these students from the Department of Mechanical Engineering, I can only pray that they will be blessed!
Of course, for Zhang Yu, these questions can only be said to be okay.
Browse the test questions generally, pick up the pen and start writing and drawing on the test paper.
The first category is to fill in the blanks. The first question is to find the general solution of the differential equation. Just follow the formula. Although the formula is a bit complicated, it can still be changed. In Lu Zhou's opinion, it is a sub-question.<
/p>
The second question is to find the equation of a straight line parallel to a certain straight line through space coordinate points. There is nothing much to say, and it is also a sub-question.
The third question is to find the derivation, and the fourth question is to find the curve integral. Points will be awarded.
The fifth question is very interesting. Through the known f(x)=... equation, and the Fourier sine series expansion of f(x) with a period of 3/2π and the function is S(x), find S
The value of (-5/2π).133
emmm…….
This is a bit difficult.
He tapped the pen on the draft paper three times, but Zhang Yu quickly figured out the answer.
This question seems a bit complicated, especially when it examines the relevant knowledge points of Fourier sine series and jointly examines the quadrature of equations. The partial equation is not very simple. But once you figure out the solution, it seems complicated.
The calculation process is actually not that difficult, it’s all a matter of smooth sailing.
At least that's the case for Zhang Yu, who spends all day in the library.
Then, he looked at the multiple-choice questions, which were all for free points, and he ticked off the answers.
The next step is the big question, and it’s time to get down to business!
Zhang Yu was gearing up, finished warming up, and was about to start work. However, when he saw the question, he was dumbfounded...
It’s not because it’s too difficult.
But because...
emmmm…….
Is that the extent?
Zhang Yu secretly glanced to the side and saw the three clever Lin brothers next door, biting the cap of their pens with sad faces.
At this time, a buddy stood up, walked to the podium, put down his papers, and walked out the door gracefully.
Zhang Yu stood in awe.
The heroes see the same thing!
Sure enough, I'm not the only one who thinks this test paper is too easy!
Thinking of this, Zhang Yu no longer hesitated, started writing, and solved the questions on the paper. Except for the last question, which took five minutes, the other questions were basically solved within two minutes.
Picking up the test paper and looking at it to make sure there was nothing missing, Zhang Yu then looked at the draft paper that was not even a quarter of the way down, packed up his things, 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 Zhang Yu who came up to hand in the paper.
Lu Pingfang thought Zhang Yu was stumped or didn't know how to do it, so he handed in the paper in advance.
When my peripheral vision caught sight of the scroll, I immediately paused.
Yo!
It seems that I can’t do it, the whole paper is full!
Lu Pingfang took Zhang Yu's test paper in his hand and stared at it carefully.
The first question is correct.
The second question is correct.
The third question is correct.
The fourth way…….
The more Lu Pingfang read, the more frightened and serious he became. Until he read the answer to the last question, Lu Pingfang let out a long sigh of relief.
All right!
"Awesome! Why does such a good math talent stay in the Department of Mechanical Engineering and do nothing?"
Lu Pingfang planned to have a good chat with Dean Wang after the exam was over.
