Do you think Xueba is really happy?
Yes, you can’t even imagine the happiness of Xueba!
—Excerpt from
On the seventh day of National Day, college students returned to school one after another. The fastest update┏Ⅹ④③⑨⑨┛
The vitality and vitality of the past has been restored on the Tsinghua campus.
Cheng Nuo continued to carry a stack of books and came to the original location of the Celadon Internet Cafe early to start his day's work.
Tired is a little bit tired, and suffering is a bit bitter.
However, the feeling of being forced is really cool!
Yesterday, Cheng Nuo has constructed the discrete one-dimensional Helmholtz equation in ccd format.
Next is the more complicated and difficult stage of deriving from one dimension to two dimensions.
Cheng Nuo sat in front of the computer, frowning, while turning his pen, he kept searching for the steps to solve in his mind.
The huge data stream constantly converges and collides in my mind.
After sitting for more than half an hour
"Yes!"
Cheng Nuo straightened up immediately, tapped the keyboard with ten fingers, and wrote down his inspiration.
"From one-dimensional to two-dimensional, that is, to convert a single x-axis coordinate into x, y plane coordinates. Then, after constructing the two-dimensional helmholtz equation of the dirichlet boundary condition, divide the domain into equidistant networks, Get n^2 grid points"
Xi, yi)=((i-1h, (j-1)h),"
In my mind, thoughts are flying.
This question is like a woman who is embarrassed and ready to fuck, as long as she untie her first button, the rest will happen automatically!
Pop pop
Cheng Nuo tried to conquer her with both hands.
The forehead was covered with sweat at some point. But Cheng Nuo didn't mean to stop, he was still
Happiness!
This is the sound of fingers hitting the keyboard.
at dusk.
Cheng Nuo spent another whole day in the Internet cafe before dragging his tired body back to the bedroom.
For academic things, neither Ouhuang nor Krypton Gold will work.
Only if you burst your liver is the kingly way!
I don't know so many academic experts at home and abroad, all of whom have white hair early.
After exploding the liver for two consecutive days, the body of Cheng Nuo, an ordinary person, almost couldn't hold it.
After returning to the dormitory to drink a bottle of Shenbao, Cheng Nuo climbed into bed, closed his eyes, and cultivated himself.
Classes are about to resume tomorrow. Cheng Nuo must adjust his state and devote himself to learning this great and arduous career with full enthusiasm.
As for the subject
Cheng Nuo will also take time to continue studying.
After two days of exploding liver, Cheng Nuo has completed about 50% of the content of the first part of the subject.
The rest is estimated to be done in more than a week.
The next day, Cheng Nuo sat in the classroom, boringly stopping the content of a middle-aged professor on the podium.
Advanced mathematics can be regarded as one of several public courses taken by the Department of Finance in the freshman semester.
And this course is not the simplest among all the mathematics courses in the university, but it is the most basic course.
Almost all engineering majors must study this course.
As I said before, this course has been circulated in the world for a long time. Everyone has heard of it.
But for Cheng Nuo
soeasy!
Cheng Nuo, who has already listened to the professional courses in the Department of Mathematics, is really not interested in pediatrics such as advanced mathematics.
It seems that we should discuss with the instructor whether he can not attend the advanced math courses.
Anyway, he can learn all the knowledge.
Advanced mathematics includes: limit theory, univariate differentiation and integration, arc differentiation, multivariate differentiation and integration, elementary ordinary differential equations, series, spatial analytic geometry, vector algebra, etc.
Mathematical analysis includes: real number theory, limit theory, univariate differentiation and integration, multivariate differentiation and integration, series, etc.
The content is similar.
However, one is to focus on calculations and the other is to focus on theoretical proofs. And the depth of mathematical analysis is even deeper.
Cheng Nuo, who was really bored, yawned, put on headphones, and while listening to music, continued to fill in the calculation formulas and steps on the subject on the draft paper.
The high math teacher who was lecturing on the podium naturally took Cheng Nuo's actions into his eyes.
He stepped off the stage, moved to Cheng Nuo's side, and tapped lightly on his table.
咚咚!
Cheng Nuo turned his head and was jumped off by the Gaoshu teacher standing next to him. He took off his earphones shivering.
"What's your name?"
"Cheng Cheng Nuo."
"Okay, Cheng Nuo, right? In view of your behavior of not listening carefully in class, I will give you thirty seconds to finish the question on the podium."
Cheng Nuo looked up at the blackboard.
Sure enough, at the top of the blackboard was written a title:
"Suppose the polar coordinate equation of curve c is r=a^3, find the full length of curve c?"
Cheng Nuo frowned slightly.
Teacher, are you asking this question, the purpose, is to insult your IQ?
Teacher Gao Ma saw Cheng Nuo frowning, thinking that Cheng Nuo was afraid, and continued to speak, "I don't make it difficult for you. I just want the result and don't count the steps. Now time it and open."
"3/2aπ."
High number teacher: "???"
The word "beginning" of Teacher Gaoshu was not even uttered, and Cheng Nuo was abruptly choked.
Such a fast speed!
To be honest, Cheng Nuo's answering speed was unexpected by the high school teacher.
Although the topic is simple, it takes at least three seconds to let him do it himself.
But Cheng Nuo, this man, only took less than a second!
Horrible!
Teacher Gao Ma had to look at Cheng Nuo with admiration.
"Ring Ling Ling"
The bell rings after class.
Cheng Nuo was packing his schoolbags while looking at the class schedule of the math department this afternoon.
There is a high generation in the Fifth and Sixth Festival, and there is a solution in the Seventh and Eighth Festival.
Hey, the tragedy is like me, another day is full of lessons.
While Cheng Nuo was pitying himself, a graceful figure appeared in front of Cheng Nuo.
"Student Cheng Nuo, can you discuss something with you?"
It was Yan Yunqing who spoke.
Oh, yes, it is currently the monitor of Cheng Nuo's class. The top spot of the class committee!
"Yes, please speak."
Chatting with beautiful women, Cheng Nuo was very happy.
Yan Yunqing had a capable expression, "That's it. Mid-Autumn Festival is coming soon. Our college is going to hold a Mid-Autumn Festival party. The requirement is that each class must register for two programs."
"I can sign up for a show here, but there is still one short. Student Cheng Nuo, I heard you sing well. Why don't you sign up for a show too?"
Mid-Autumn Party?
Cheng Nuo really didn't know the news of the Mid-Autumn Festival party.
"Me?" Cheng Nuo pointed to himself~EbookFREE.me~Yes! "Yan Yunqing smiled and nodded, "Cheng Nuo, as a class member, you should play an exemplary role. Only in this way will your image among classmates grow taller. "
"Besides, there are rewards for participating in this party?" Yan Yunqing smiled mysteriously.
Cheng Nuo's eyes lit up, "Reward? Is it credit?"
Yan Yunqing smiled and shook his head, raising a finger, "No, it's a bag of moon cakes."
Cheng Nuo: ""
In the end, under Yan Yunqing's every possible persuasion, Cheng Nuo finally agreed to perform on stage. However, there are conditions.
"However, I need an instrument to play with me on stage. Make the performance perfect. If you can borrow it for me, I promise to play."
Yan Yunqing said, "No problem, let's talk about it, what kind of musical instrument it is, I will go to the senior and senior sister to borrow it."
Cheng Nuo spit out two words lightly: "Erhu."
