This passerby is too calm

Chapter 142
And there is more than one such person in their class.

"Morning monitor!"

"morning."

Chen Mo glanced over, and there were only a dozen or twenty people in their video communication class, and almost half of them came.

Under the lights, everyone was quietly doing their own things in their own positions.Or take a new oriental green leather level [-] memorizing vocabulary, and quietly recite the vocabulary.Or take an iPad pencil to fish and draw a manuscript on Procreact.Someone moved an easel from the corner of the wall, placed a group of small still lifes for himself on the small table, and tried to draw oil paintings with oil paints.Three or four people moved the table together and got together. There was a large piece of paper on the table, and there were various light-colored small scraps of paper on it. They seemed to be discussing about making a work.

It is not the homework assigned by the teacher, but the work that the students find for themselves.

The curtains were half opened, and the sunlight poured unobstructed on the entire class.Everyone is busy doing their own things, calm and serious.

Chen Mo looked at all this, and for some reason, the corners of his mouth slightly curled up.

very nice.

This is the University of A, and this is indeed the University of A.

No one who can come in is someone who has no demands on himself.

……

Chen Mo sent a message in the group and asked the rest of the students to come to the classroom, and then began to organize the students to clean up.

Find a few boys and go to Building 21 together, and move the plaster David statue and books of various subjects needed for tomorrow's modeling basic class to the studio.

Asking the students to prepare cash, Chen Mo began to collect and count the money.

While the students were running around collecting cash, Chen Mo, who had cleared his place, sat on the chair and calculated the students' money that had already been paid, and finally heaved a sigh of relief.

But I heard the three people with a bunch of small notes piled up in front of them chatting.

"I feel that the main purpose of this competition is patriotism. When I saw the name of the competition, the first image that popped up in my mind was the flood in Province Y. There are many points that can be made."

"That's what I thought too. But what do we do? Have you found a suitable reference image?"

"On the Internet, or Xiaohongshu, Tuchong... Look around to see if you can find it."

"There are too many things that can be done, and none of us are from Province Y, and the photos we found on the Internet are all other people's, so it's not good if there are too many references.

Some time ago, I saw a student team from a well-known university participate in this kind of similar competition. They used the works of other bloggers and big Vs. Basically, they used other people’s ideas and actions intact, but changed animals and made them on accessories. A little change, but it can be seen at a glance that it is a reference to plagiarizing the blogger's work.Later, it was announced because it won the first prize, and the big V found out that he had hung up the person.The school and students plagiarized and lost a lot of face.

Let's take it easy, if we can find some works that we have taken for reference, we will do so. "

"But where do we get pictures of the floods?"

"If it doesn't work, we can change it. How about taking some photos near us? How to travel and so on."

"No, it's too common."

Just when the discussion of several people reached a deadlock.Chen Mo turned his head and interjected in doubt.

"what match?"

"Ang, monitor, are you interested in joining us? Give us some advice, save the children."

"Let's talk about the game first."

"It's a competition we saw online called 'My Vision, My Country Z', a large-scale competition co-organized by People's Daily and Country Z Photography magazine.

It should be these two days, and the college should also send out a notice.I just heard from former seniors and sisters that competitions are rarely open to undergraduates, let alone freshmen.Because of the high gold content, many teachers will participate.It is very unlikely that we will win an award or even be selected, but it would be a pity not to participate in this kind of competition.We're going to join in the fun. "

"A group match?"

"Both groups and individuals can participate."

"Squad leader, do you want to give it a try? You are lucky enough to be selected. If nothing else, the comprehensive test score will definitely increase a lot."

"Okay, add me. Are you handing in photography? You guys are..."

Chen Mo thought of the pile of small scraps of paper in front of the three of them, and asked suspiciously.

"Hey, there is no requirement that it must be a photograph, it can be a painting, calligraphy, sculpture, composite material, or essay, as long as it fits the theme.

We originally wanted to make comprehensive materials, use paper to paste pictures, or make three-dimensional effects, thinking that if the subject matter is not attractive enough, the work may make up for it if the work is more eye-catching.

In the end, I didn't expect to think about how to do it, but I got stuck in choosing the subject matter.Originally, the three of us wanted to do a theme of the flood in Y province some time ago, but Zhang Yuan was very stubborn. He insisted that he couldn’t use the photos on the Internet, and wanted to shoot the materials himself. Where can we get him. "

Chen Mo laughed.

"If it's a photo of the flood in Province Y, I actually have it. I have a friend who happened to go to Province Y during the flood a while ago, and he took a lot of photos..."

……

A whole morning, several people spent discussing the entries.After urging the last few people to pay the textbook fee on WeChat, Chen Mo said goodbye to the few people who had collected all the money, reminded them to remember to take the student handbook, and rushed to the school financial office under Building 8 to pay. Book fees for the class.

A busy day, Chen Mo has been running around.Chen Mo only found out in the afternoon that many of the university's arrangements are actually based on the teacher's mood and can be adjusted.

For example, the class meeting was originally scheduled for [-] pm. Because some students reported that the class meeting conflicted with their homework time, the counselor and the class teacher communicated and decided to postpone the class meeting to noon tomorrow. After the class in the morning, let the students Leave it for half an hour, simply open it.

Very adaptable.

As a result, Chen Mo, who was so busy, was inexplicably free in the afternoon.

I did not choose to go to the Forbidden City and the Summer Palace to gather folk songs like other students.With a camera on his shoulder, Chen Mo walked around the campus of University A. A few days ago, he noticed that there are many old-style displays and buildings on the campus of University A.Because this is the place designated by the Summer Palace, there are many beautiful scenery and iconic buildings inside.

Time always flies by quickly.

"Woo woo┭┮﹏┭┮."

"what happened?"

While drawing sketches on the ancient house, Chen Mo answered the call from Bai Yitong.

"Momo, advanced mathematics is not something that humans learn at all! Huh, huh, huh... I haven't read mathematics for a whole summer vacation. How come it doesn't know me when I know it? It feels like the knowledge you gave me back then, I gave it all back to you."

"What's the matter, are you looking at high numbers?"

Chen Mo put the phone on his shoulder and clamped it between his head, took down the pencil in his mouth, continued to draw, and said with a smile.Hearing Bai Yitong's cowardly and angry tone, he couldn't help but think of Bai Yitong's angry expression [○｀Д○] with a puffed up face, his eyes were full of smiles.

"En." Bai Yitong nodded aggrievedly.

"Isn't school starting tomorrow?"

Bai Yitong wanted to cry even more when he heard it, and complained in a delicate tone:

"Tomorrow afternoon we are all taking advanced mathematics courses, and we still have four classes in a row."

"Well, it's a bit too much, too much." Chen Mo followed Bai Yitong's words.

"Right~"

"The teacher left homework, let us preview it in advance. I drew the range and said that there is a placement test. I saw that my classmates in the same dormitory were doing the questions, so I took out the book and looked at it..."

"In the end, you forgot everything?" Chen Mo smiled and helped his girlfriend finish the rest.

"En." Bai Yitong replied in a small voice.

"Huh?" Chen Mo raised his eyebrows amusedly.

"Actually, in fact... it's not all forgotten."

Bai Yitong was cowardly and extremely wronged.

After Chen Mo finished the last stroke of the dragon pattern on the eaves, he smiled and shook his head.

"Okay~ I see, I'll come to you after I've dealt with the matter here."

Chen Mo said dotingly.

"Really?"

"Well, I don't have much to do today, so I just need to draw a few pictures, just to help you read the next question."

"\(^o^)/Okay, with Ah Mo helping me, I will definitely pass the exam tomorrow! Ah Mo is the best! Ah Mo is the best!!"

Chen Mo could already imagine Bai Yitong's little expression waving the flag and shouting. If Bai Yitong was in front of him, he would definitely reach out and pinch her little nose vigorously.

Helplessly shook his head.

When Bai Yitong was in high school, he didn't like to take math classes, and the worst thing in all subjects was math.But what is rare is that she is good in physics and chemistry, but she is poor in mathematics.In the last few months of high school, she sat next to him and looked at him pitifully, but she just didn't dare to speak.

Originally, he was just waiting for this silly girl to speak up, but one day he saw Bai Yitong biting the signature pen and making himself cry when doing math problems, so he still gave up.He can't see people crying, but he is still the one he likes.

……

"Looking at these questions, my Xiaobai is pretty good. Generally speaking, you still remember the basic elementary functions, that is, compound functions, parametric functions, implicit functions, and piecewise functions. We are not familiar with it... Practice a few questions for this piece, and I will circle a few for you, and you can try it according to what I just told you."

"Good~"

Bai Yitong replied obediently.

After a while, Bai Yitong stopped the pen in his hand, tilted his head and looked at Chen Mo who was outlining the ancient architectural drawings in the sketchbook, and suddenly asked, thinking of something:
"Amo, doesn't your academy of fine arts have advanced mathematics courses?"

"No, generally this kind of courses are taught by science colleges. Art colleges don't need to study."

"Oh, that's such a pity~ It's too reckless, Amo's brain is simply born to learn advanced mathematics."

While talking, Bai Yitong quietly put down the pen, quietly moved his chin to the water glass, propped his head up and looked up at Chen Mo, and said with eyes full of admiration, his mouth was babbling, and Rainbow farts kept clapping.

"What kind of strange description do you mean?"

Chen Mo smiled helplessly, and tapped Bai Yitong's forehead lightly with a signature pen.

"Don't interrupt, read the question carefully."

"Ouch~"

Bai Yitong wrinkled his nose, pouted his small mouth, gently rubbed his forehead with his bangs, and continued to speak softly and innocently.

"That's right~ It's a pity that our Amo is so good and doesn't learn advanced mathematics! Actually, I have already discovered that you don't need to count many questions. I feel that sometimes you can get the approximate result at a glance. Understand it, deliberately reverse the process that I can understand, write it down, and then tell me.”

Chen Mo smiled helplessly, but did not deny it.

The little silly girl guessed right, he could indeed see the results of most of the questions at a glance. After playing the IMO (International Mathematical Olympiad) for so long, although at the last moment, there was an accident and he did not continue to play, but his sensitivity to numbers is actually much higher than that of ordinary students.

Countless competition topics are piled up.

The various logical thinking modes in the mind that are reflected instantly when seeing numbers have become instincts through countless trainings.In other words, in fact, many patterned questions and special numbers can be instantly grasped and related in his mind, and the results have been obtained before he can react.It's as logical as one plus one equals two, no need to think.

And the process he explained to Bai Yitong was to take the cognitive result that the brain that one plus one equals two took for granted before slowing down and deriving it again, and then explain it clearly to Bai Yitong.

He raised his hand and rubbed Bai Yitong's head.

"Look at the question, Xiaozui, don't interrupt and change the subject, it's useless. No matter what happens today, you have to pass the limit of the function and the one-dimensional calculus."

"Oh~, that's great."

"Ok?"

"Swear to the organization and promise to complete the task!"

Bai Yitong pursed his lips, responded aggrievedly, and obediently moved his head back.She cheered up and looked at the subject with piercing eyes, as if she was not looking at the subject but her class enemy.But looking at it twice, tears are about to come down.

This is not something that can be done when the spirit is up.

Chen Mo looked helpless and funny.

"Come on, open your mouth."

"what."

"Eat something and you'll feel better."

After Chen Mo fed a piece of bread, he kissed Bai Yitong's swollen cheek like a little hamster, and continued gently.

"Come on, dear~ This question is actually not difficult, limx→01cosxcos2x√cos3x√3x2. And there are quite a lot of solutions... Roughly speaking, there are at least eight solutions, as long as you write one correctly, I will write a few for you , which one is easier to understand.

The first one is to use L'Hopital's rule, equivalent infinitesimals and continuity theorem. When x→0, it is easy to find that the problem is a 0/0 type indeterminate limit. Using L'Hopital's rule, the original formula is equal to...Since x→ When 0, sinx～x, and use the continuity theorem to get limx→01cosxcos2x√cos3x√3x2=3.The second is the simplification of the identity transformation, and then use the equivalent infinitesimals and the continuity theorem..."

In the self-study room, Chen Mo whispered the topic to Bai Yitong.
