"I feel that Bai Yitong's boyfriend must have participated in mathematics competitions. Even if it is not IMO, he must have participated in other similar competitions. Many of the questions behind this set are competition content. It is impossible for him to achieve such results without participating in competitions.
.How is it? Have you heard of or know him? I feel like he should be quite famous."
"It's true that I don't look like a nobody in the competition circle. This kind of ability should be quite popular in the circle, but why don't I feel that I have no impression? Is it because I have participated in less competitions?"
"I have no impression either."
"Me too. Anyway, I haven't seen him in our IMO provincial competition. Maybe he is not from our province..."
…
All the top students had doubts on their faces at this time. They did not feel that they had a deep impression of Chen Mo, but Chen Mo didn't act like they didn't know him.
A boy with a handsome face among the group looked at Chen Mo, his eyelids narrowed slightly, with a somewhat searching and unconvincing look in his eyes.
This man's name is Meng Ziyu. Different from his low-key appearance, he is actually a player in the IMO national competition. He has always been relatively reserved and low-key. He has never told anyone that he has entered the IMO national competition. At that time, he competed with various provinces
When the top players participated in the pre-match training in City A...
He felt as if he had met Bai Yitong's boyfriend.
At this moment, he looked at Chen Mo's back, which looked familiar, reminding him of his fear of being dominated by a pervert.
But how could that perverted guy who even the training teachers marveled at be admitted to University A so smoothly? If it was really that guy, the school couldn't have been so calm and didn't say anything. They
It's impossible not to get any news at all.
"How about Meng Shen? Do you know him?"
"How should I put it? I can only say that I think he looks a bit familiar..."
If the Chen Mo in the front row was really a big shot in the competition with him, he really couldn't understand why this person would apply for the Academy of Fine Arts.
"look familiar?"
…
"Fangquan scored 88 points..."
After hearing the results reported by the teacher, Fang Quan's hand holding the paper tightened slightly.
It might seem like a ten-point difference, but he and all the top students in the class knew that this short ten-point gap was a huge gap... He asked the teacher about his deduction points, and he was given three points for the last question.
, but he was deducted three points for the previous question because he did not have time to check it.
But Chen Mo's 98 points is not really 98 points...
The few people who had gathered around Fang Quan and helped him talk about Chen Mo at noon had interesting expressions on their faces at this time, but they all glanced at Fang Quan subconsciously.
The person with the most depressed mentality is probably Fang Quan.
Someone patted Fang Quan on the shoulder and asked carefully:
"Fang Quan, are you okay..."
"……fine."
Fang Quan smiled at the brother beside him, but the gloom on his face still did not fade away, and he gritted his teeth and said.
He actually wanted to ask the teacher to take a look at Chen Mo's test paper. Chen Mo's results were really incredible.
He was wondering whether Chen Mo knew the answer in advance, so he just wrote it down silently. Didn't the teacher also tell him? Chen Mo skipped steps in writing.
Maybe where did he get the answer?
Although it is disgusting to think this way, and although he also knows that Professor Li’s character makes it impossible for others to get the answer from him, what he hates most is this kind of thing. But... maybe?
Fang Quan knew that it was not good for him to think like this, but there was still a trace of luck in his heart. He really had no way to convince himself and change his mentality.
In fact, he was not the only one in the class who thought so.
…
After Teacher Lu reported the results, he supported the desk with a smile, looked down and said.
"Okay, everyone knows the results. I think the students are mentally prepared. Come on, let's start talking about the questions. Listen carefully. There are many knowledge points in it that you will use after you are divided into classes.
From this moment on, your college career in advanced mathematics has officially begun. Listen well!"
"Okay, let's start now. I just skipped the previous questions. I didn't see many mistakes when I judged the paper before. I passed it. Everyone just turned to the seventh question..."
…
"Ah Mo, I didn't understand the question just now." Bai Yitong said, pulling on Chen Mo's clothes.
"Okay, I'll say it again."
"It's actually not difficult, don't be nervous. Look, the function f(x)=sinx/1x2, the cubic Taylor polynomial at x=0 is axbx2cx3, from this we can know...or you can also draw one first
picture……"
Just like that, Teacher Lu Ming was talking from above, and Chen Mo was talking to Bai Yitong in a low voice below.
Because the two of them were very close to Teacher Lu Ming, Chen Mo's voice was very quiet to them, but he could still clearly hear Chen Mo's lowered voice as long as he listened carefully.
From time to time, Lu Ming lowered his eyes to look at the young couple after finishing the topic, twitching the corners of his mouth, looking at Chen Mo who was explaining the topic to Bai Yitong seriously, and then looking at the full formulas and steps written by Chen Mo on the draft paper, Lu Ming said
Time and mood are so complicated.
Isn’t this quite complete? You can even write down several solutions! Why can you be so patient and detailed when giving a topic to your girlfriend, and why can you be so concise when you write it yourself?
At this time, the little doubt in his heart about Chen Mo disappeared. This kid really wrote it all by himself, he just didn't bother to write the process at all.
"Classmate Chen Mo, come on, don't talk to your girlfriend down below. Come up and talk to your girlfriend."
"Um?"
Chen Mo, who was touched again, raised his face in confusion, and blinked his eyes in the admiration of Teacher Lu Ming.
"You are almost running out of scratch paper. Do you want to come up and try the blackboard? There are four blackboards, which are enough for you to write happily. Do you want to come up?"
…
"...So when x→0, ln[1(cosnx?1)]～cosnx?1～?n2x22ln[1(cosnx-1)]～cosnx-1～-n2x22, it is easy to solve by substituting it into
The answer to the question.”
In the end, Chen Mo was coaxed onto the podium by his classmates, and reluctantly started talking about the topic. But what Chen Mo didn't expect was that after this lecture, he never came down again.
"That's very good. I thought you couldn't write down the steps in detail before. Now you can't even read them and write them very well? Keep going..."
Chen Mo twitched the corner of his mouth, wanting to spit out the chalk.
I don’t know why, but Chen Mo was taking classes in the business school and somehow got to the podium and lectured on mathematics for most of the class.
"Let xn1=μxn(1-xn) be the nonlinear characteristic equation of fiber optic gyro error measurement. For the system matrix of appropriate dimension x=(x1,...,xm)T∈GF(2n)m, the fiber optic gyro error measurement
Distribution feature set A=(aij)m×m,aij∈GF(2n), using the fusion analysis method to obtain the statistical distribution set of fiber optic gyroscope errors..."
"Then how do you calculate the constraint parameters of the fiber optic gyroscope? There is still a theoretical stage and there is no way to calculate it further?"
Fang Quan raised his hands and stood up to ask. He looked directly at Chen Mo. At this time, there was no disdain and disbelief in his eyes. Although it was a little awkward, he had to admit that Chen Mo's previous performance had also impressed many of his classmates.
The top student in school responded fluently to his questions, allowing him to completely shatter all kinds of dirty speculations.
The fleeting suspicion that Chen Mo might know the answer was completely buried by his shyness to see others.
After truly subconsciously agreeing with Chen Mo's abilities and establishing this understanding, Fang Quan found that he didn't hate Chen Mo so much anymore.
Maybe he is a man in science and engineering, and he still prefers data and theory to women.
When he heard Chen Mo explain this, he still couldn't hold back the strong doubts in his heart. He had been stuck here when he was doing this question before. He suppressed the awkwardness and embarrassment, and the tips of his ears burned red.
But he still stood up and asked Chen Mo his questions.
But after asking, he suddenly realized that he regretted it. If Chen Mo ignored him, it would be really embarrassing...
Chen Mo glanced at Fang Quan and said nothing. He threw the piece of chalk that was only about the size of a fingernail into the groove under the blackboard. He walked to the podium and picked up another piece of chalk. He walked to the blackboard and continued writing.
, while explaining to him seriously as if answering questions for other students before.
"So now we have to set k1, k2, and k1 is the maximum conjugate gradient of the fiber optic gyro error; k2 is the continuous functional of the fiber optic gyro error distribution. The constraint parameters of the fiber optic gyro error are... Using boundary constraints,
By conducting fiber optic gyroscope error analysis, we can obtain the inertia characteristic quantity of the error measurement...is this understandable?"
As Chen Mo spoke, he quickly wrote down concise words and formulas on the blackboard. After giving a rough explanation, he turned his head and looked at Fang Quan and asked.
Fang Quan was stunned for a moment. He didn't expect that Chen Mo would actually answer him. After all, they were so tense at noon that they almost started fighting, and he was still talking about him behind his back. He must know...
In this way, he still...
Fang Quan felt for a moment that he was a bit of a loser.
He rubbed his index finger and thumb on the table unconsciously for a long time, then looked at Chen Mo and opened his mouth for a long time.
"Li...I understand, thank you."
"Well, okay, let's continue... If you have any questions, you can ask them."
"Then what, I still have questions...how to optimize the measurement of these errors and integrate the errors?"
The person who asked the question was still Fang Quan. He is indeed very smart. His emotional intelligence is a little hard to describe, but his IQ is nothing to say. Because he is the only person in the class who has had some contact with Teacher Li before, he is also the only one in the class who can
Someone who can keep up with Chen Mo's ideas.
Compared with the top students in other classes, he has the most doubts, but he can get an idea from every question. He can also be brave enough to ask Chen Mo one by one.
Chen Mo raised his eyebrows but did not refuse. Fang Quan asked about a link and he explained it. He took a piece of chalk and kept writing the corresponding formulas and results on the blackboard.
…
"Use orthogonal functions to solve... The fiber optic gyroscope error parameter fusion characteristic quantity is expressed in the form of 6)x (t)=Ax(t)Bu(t) and uc(t)=Kxc(t), so that
Closed-loop system... Combined with the automatic optimization method of orthogonal functions to adaptively solve the fiber optic gyroscope error, and obtain sufficient conditions for output stability... Use the global asymptotic stability analysis method to analyze the fiber optic gyroscope error characteristics to improve the accuracy of the fiber optic gyroscope error.
Measurement accuracy.”
"Ang!! What a great idea, why didn't I think of that! Then we can measure the error of adaptive optimization!"
Fang Quan raised his hand and patted it hard, as if the roots of his hair were standing on end. He was very excited and happy. It took him nearly forty minutes during the exam and he couldn't solve the question, which made his brain knotted.
, it suddenly became smooth, and Fang Quan felt indescribably comfortable and excited at this moment.
The happiest thing in the world is nothing more than this.
"Well, yes."
Chen Mo nodded affirmatively.
Fang Quan happily showed a bright smile. If he wanted to leave him alone, if he wasn't really awkward and embarrassed, he would have rushed up and picked up Chen Mo without caring about anything. This guy is so awesome.
Really awesome.
He followed the train of thought completely and then felt the unbelievable shock that was natural.
"The next step is the finishing work. Everyone has guessed it, which is to draw an error distribution diagram, and then get the analytical formula: x=AxBu, y=CxDu, and then get the set of models... fiber optic gyroscope error characteristic solution x
=[φ,ψ,P,r,v,ye]T, output u=[δa,δr].
To sum up the above analysis, we can optimize the mathematical model of fiber optic gyroscope error measurement. Okay, this question is over."
When Chen Mo finished speaking, he stabbed the white chalk hard on the blackboard, ending the explanation of the entire topic.
"Teacher, can I go down now?" He really couldn't finish the lesson.
In the end, it was up to him.
Except for Fang Quan, who was grinning excitedly with his front teeth exposed, everyone else in the classroom was very quiet at this time.
Look at the blackboard quietly.
At this time, in the lecture theater, the four large blackboards, occupying almost the entire wall, were covered with white chalk. They were all densely packed with words and formulas, and could only be described as shocking.
Following Chen Mo's train of thought, everyone didn't feel anything when they were listening to the class together. They just felt that a stroke of chalk was very beautiful. But when they couldn't follow in the middle, or when they finished listening to the entire question, they looked at the blackboard.
I suddenly realized that this guy could write characters incredibly fast.
TM: Are this guy's hands flying on the blackboard? He doesn't seem to be in any hurry at all. Why is it that the blackboard is filled with writing in the blink of an eye?
Everyone looked at the dense text and formulas on the blackboard, and suddenly understood how this guy could finish writing the paper in such a short time and hand it in early.
"teacher?"
"...Oh, ok, is it finished?"
Lu Ming suddenly came back to his senses, responded, looked up at the words on the blackboard, and asked with complicated eyes.
"No, I can't write it on the blackboard. I expanded it on the basis of my test paper, but it's not complete yet."
