Do you think the top student is really happy?

Yes, you can't imagine the happiness of a top student!

———Excerpt from "Quotes of Cheng Nuo"

…………

On the seventh day of National Day, college students returned to school one after another.

On the Tsinghua campus, the vitality and vitality of the past have been restored.

Cheng Nuo continued to carry a stack of books and came to Qingyao Internet Cafe early to start his day's work.

I am tired, and I am bitter.

But, the feeling of being pretentious is really... so good!

Yesterday, Cheng Nuo had constructed the discrete one-dimensional Helmholtz equation in the ccd format.

Next, the more complex and difficult stage of deriving two-dimensional from one dimension.

Cheng Nuo sat in front of the computer, frowned, and turned his pen while constantly searching for the steps that the person solved in his mind.

Huge data flows are constantly intersecting and colliding in my mind.

After sitting for more than half an hour...

"Have it!"

Cheng Nuo immediately straightened his body, typing on the keyboard with his ten fingers, and noting down his inspiration.

"From one-dimensional to two-dimensional, a single x-axis coordinate is converted into x and y-plane coordinates. Then, after constructing the two-dimensional helmholtz equation of the dirichlet boundary condition, the definition domain is divided into an equidistant network, and n^2 grid points are obtained..."

“(xi,yi)=((i-1h,(j-1)h),……………”

In my mind, my thoughts were flying.

This question is like a shy woman waiting to be fucked. As long as she unbuttons her first button, the rest will come naturally!

Smack sex~~

Cheng Nuo tried hard to conquer her with both hands.

My forehead was covered with sweat at some point, but Cheng Nuo did not want to stop, and he was still...

Slap sex!

This is the sound of finger tapping on the keyboard.

…………

In the evening.

Cheng Nuo had a heartache in the Internet cafe for a whole day before dragging his tired body back to the dormitory.

Academic things, both European emperors and krypton gold cannot work.

Only the liver is the king!

I can’t see so many academic giants from ancient times, China and abroad, all of whom have turned gray early.

After two consecutive days of liver failure, Cheng Nuo, an ordinary person, was almost unable to hold on.

After returning to the dormitory to drink a bottle of kidney treasure, Cheng Nuo climbed onto the bed, closed his eyes, and cultivated himself.

Class will resume tomorrow, and Cheng Nuo must adjust his condition and devote himself to learning this great and arduous cause with full enthusiasm.

As for the topic...

Cheng Nuo will also take time to continue his research.

After two days of experiencing pain, Cheng Nuo has completed about 50% of the content of the first part of the project.

The rest is probably going to be done in more than a week.

…………

The next day, Cheng Nuo sat in the classroom, and a middle-aged professor on the podium was bored and talked about the content of "Advanced Mathematics".

Advanced mathematics is one of several public courses taken by their finance department in the first semester.

Although this course is not the simplest among all mathematics courses in universities, it is the most basic course.

Almost all engineering majors need to study this course.

As mentioned before, this course has been rumored in the world for a long time. Everyone's eyes changed.

But for Cheng Nuo...

so easy!

Cheng Nuo, who has already listened to the mathematics department's major course, really can't be interested in pediatrics such as advanced mathematics.

It seems that we should discuss with the instructor whether he can avoid taking advanced mathematics courses in the future.

Anyway, he can learn all the knowledge of "Advanced Mathematics" in "Mathematical Analysis".

Advanced mathematics includes: limit theory (but does not contain basic proof), monovariate differential and integral, arc differential, multivariate differential and integral, elementary ordinary differential equations, series, spatial analytical geometry, vector algebra, etc.

Mathematical analysis includes: real number theory, (from three perspectives, Dedekin segmentation, interval set, and sequence explains how rational numbers expand to real numbers), limit theory, (including basic proofs, such as the proof of Cauchy's convergence theorem), univariate differential and integral, multiple differential and integral, series, etc.

The content is similar.

However, one focuses on calculations and the other focuses on theoretical proofs. Moreover, the depth of mathematical analysis is even deeper.

Cheng Nuo, who was really bored, yawned, put on his headphones, and while listening to the music, he continued to fill in the calculation formulas and steps of the topic on the draft paper.

The senior mathematics teacher who was teaching exercises on the podium naturally took Cheng Nuo's actions into his eyes.

He walked off the podium, moved to Cheng Nuo, and gently tapped on his table.

Dongdong!

Cheng Nuo turned his head and was jumped by the senior mathematics teacher standing beside him. He trembled and took off his headphones.

"May I have your name?"

"Cheng...Chengnuo."

"Okay, Cheng Nuo, right? Given your behavior of not listening carefully in class, I will give you thirty seconds to limit you to the question on the podium."

Cheng Nuo looked up at the blackboard.

Sure enough, there was a question written on the top of the blackboard:

"Suppose the polar coordinate equation of curve c is r=a(sinθ/3)^3, find the full length of curve c?"

Cheng Nuo frowned slightly.

Teacher, is your purpose in posing this question to insult IQ?

Seeing Cheng Nuo's frowning look, the senior mathematics teacher thought it was Cheng Nuo who was afraid, so he continued to speak, "I don't make things difficult for you. I just want the result and don't calculate the steps. The time is below, and it starts..."

“3/2aπ.”

Senior mathematics teacher: "???"

Before the word "star" was expressed by the senior mathematics teacher, Cheng Nuo was forced to touch his mouth.

Such a fast speed!

To be honest, Cheng Nuo's answering speed was unexpected by the advanced mathematics teacher.

Although the question is simple, it will take at least three seconds to let him do it himself.

But Cheng Nuo, a man, only took less than a second!

It's so scary!

The senior mathematics teacher had to look at Cheng Nuo with admiration.

...

"Lingling..."

The bell rang.

Cheng Nuo packed his schoolbag while looking at the math department’s class schedule this afternoon.

There is a high-generation section in the five and sixth sections, and there is a few sections in the seven and eighth sections.

Alas, the tragedy is like me, and it is another full class of the day.

Just as Cheng Nuo was feeling sorry for himself, a graceful figure appeared in front of Cheng Nuo.

"Student Cheng Nuo, can you discuss something with you?"

Yan Yunqing is the one who speaks.

Oh, by the way, it is the number one seat of the class monitor and class committee member of Cheng Nuo and his class!

"Yes, please speak."

Chatting with the beautiful girl, Cheng Nuo was so happy.
