This passerby is too calm

Chapter 151 149

"I feel that Bai Yitong's boyfriend must have participated in math competitions, even if it's not IMO, he must have participated in other similar competitions. Many of the questions behind this set are competition content. He can achieve such results, it is impossible for him not to have participated in the competition." How is it? Have you heard of or known him? I think he should be quite famous."

"It's true that he doesn't look like someone unknown in the competition circle. This kind of ability should be very popular in the circle, but why do I feel that I don't have any impression? Is it because I have participated in fewer 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..."

……

At this time, all the top scholars are full of doubts. They really feel that they don't have a deep impression on Chen Mo, but Chen Mo's behavior really doesn't look like they don't know him.

Among them, a boy with a more handsome face, when he looked at Chen Mo, his single eyelid narrowed slightly, and there was some inquiry and a look of incredulity in his eyes.

This person's name is Meng Ziyu, and unlike his low-key appearance, he is actually a contestant in the IMO national competition.He has always been relatively introverted and low-key, and he has never told everyone that he has ever entered the IMO national competition.When I participated in the pre-competition training in City A with the top players from various provinces...

He felt as if he had met Bai Yitong's boyfriend.

At this time, he looked at Chen Mo's back and it looked so familiar, which reminded him of the fear of being dominated by a certain pervert.

But how could the perverted guy who was amazed by even the teachers in the training camp be admitted to University A so calmly.If it was really that guy, it would be impossible for the school to be so calm and say nothing, and it is impossible for them not to get any news.

"How about God Meng, do you know him?"

"How should I put it, I can only say that I think he looks familiar..."

If the Chen Mo in the front row is really the boss of the competition with him, he really can't understand why this person would apply for the Academy of Fine Arts.

"look familiar?"

……

"Fang Quan scored 88..."

Hearing the grades reported by the teacher, Fang Quan tightened his grip on the paper slightly.

Maybe it seems that there is a very big gap, but he and all the top students in the class know that this short and very bad thing is Tianzhu... He asked the teacher about his own points, and the last question gave him three points , but because he didn't have time to check the previous question, he was deducted three points.

But Chen Mo's 98 points are not really 98 points...

The few people who surrounded Fang Quan and helped Fang Quan talk about Chen Mo at noon before had a bright expression on their faces, but they all subconsciously glanced at Fang Quan.

The one with the worst mentality should be Fang Quan.

Someone patted Fang Quan on the shoulder and asked cautiously:

"Fang Quan, are you okay..."

"……fine."

Fang Quan smiled at the brother beside him, but the gloom on his face still did not fade, and he gritted his teeth and said.

In fact, he really wanted to know that he asked the teacher to take a look at Chen Mo's test paper, because Chen Mo's grades were so unbelievable.

He was wondering if Chen Mo knew the answer in advance, so he just wrote it silently, didn't the teacher also say it?Chen Mo writes by skipping steps.

Maybe where did he get the answer?
Although it is very dirty to think so, although he also knows that with Professor Li's character, it is impossible for others to get the answer from him, what he hates the most is such a thing.But... maybe?

Fang Quan knew that it was not good for him to think like this, but there was still such a sliver of luck in his heart, and he really had no way to convince himself to change his mentality.

In fact, he is not the only one in the class who thinks so.

……

After reporting the grades, Mr. Lu supported the podium table with a smile, looked down and said.

"Okay, everyone knows the grades. I think the students are all mentally prepared. Come on, let's start talking about the topic now. Listen carefully. There are many knowledge points in it that you will use after class assignment. From this moment on, your university's high-level mathematics study career will officially begin. Listen to it!"

"Okay, let's start now. I'll just skip some of the previous questions. I didn't see a few mistakes when I was grading the test papers. It's over. Let's just turn to the seventh question..."

……

"Amo, I didn't understand that question just now." Bai Yitong said while tugging at the corner of 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/1+x2, the Taylor polynomial of degree 0 at x=3 is ax+bx2+cx3, from this we can know...or You can also draw a picture first..."

In this way, Teacher Lu Ming spoke on top, while Chen Mo whispered to Bai Yitong below.

Because the two were very close to Teacher Lu Ming, their voices to Chen Mo were very low, but as long as he listened carefully, he could still hear Chen Mo's low voice clearly.

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, looked at Chen Mo who was giving Bai Yitong a serious lecture, and then looked at the formulas and steps written by Chen Mo on the draft paper. Time mood is called a complex.

Isn't this quite complete?Can write several solutions!Why is it so patient to write such detailed questions for my girlfriend, and why is it so concise when I write them myself?

At this moment, the little doubt in his heart towards Chen Mo also disappeared. This kid really wrote it all by himself, but he was just too lazy to write the process.

"Student Chen Mo, come on, don't tell your girlfriend down here, go up and talk about it."

"Ok?"

Chen Mo, who was caught by Q again, raised his face in a daze, and blinked his eyes in the admiring expression of Teacher Lu Ming.

"You are almost running out of draft 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?"

……

“……所以当x→0时，ln[1+(cosnx1)]cosnx1n2x22ln[1+(cosnx-1)]cosnx-1-n2x22，代入易求解.这就是这道题的答案。”

In the end, Chen Mo was coaxed by his classmates to go to the podium, and he talked about the topic helplessly.But what Chen Mo didn't expect was that after this lecture, he never came down again.

"It's very good. I thought you wouldn't know how to write in detail if you didn't write the steps. Now, don't you see that everything is well written? Keep going..."

Chen Mo twitched the corners of his mouth, wanting to breathe out the chalk.

For some unknown reason, Chen Mo rubbed his hands on the class of the business school, and inexplicably got to the podium, where he lectured on mathematics for most of the class.

"Let xn+1=μxn(1-xn) be the nonlinear characteristic equation of FOG error measurement, for a system matrix x=(x1,...,xm)T∈GF(2n)m of appropriate dimension, FOG error Sparse matrix of measurements β=(β1,…,βm)T∈GF(2n)m, where, n=1, 2, 3,…, x∈[0], μ∈[1], fiber Gyroscope error distribution feature set A=(aij)m×m, aij∈GF(0n), adopt 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 down?"

Fang Quan raised his hand and stood up and asked, looking directly at Chen Mo, his eyes no longer had contempt and unwillingness to believe.Although it was a bit awkward, he had to admit that Chen Mo's performance before, and his fluent answers to the questions of many top students in the class, made him completely shatter all kinds of dirty guesses.

The fleeting guess that Chen Mo might know the answer before was completely buried by his embarrassment in seeing others.

After subconsciously agreeing with Chen Mo's ability, Fang Quan found that he didn't hate Chen Mo that much anymore.

Maybe he is a man of science and engineering, and he still prefers data and theory than women.

Hearing Chen Mo explain this, he still couldn't hold back the strong doubts in his heart. He was stuck here when he was doing this question before. But he still stood up and asked Chen Mo his own question.

But after asking, he suddenly came to his senses and regretted it, if Chen Mo ignored him, it would be really embarrassing...

Chen Mo glanced at Fangquan, didn't say anything, threw the chalk stub that was only the size of a fingernail into the groove under the blackboard, walked to the podium, picked up a piece of chalk, walked to the blackboard, and continued writing. , while explaining to him seriously, as if answering questions for other students before.

"So we have to set k1 and k2 now, and set k1 as the maximum conjugate gradient of the fiber optic gyroscope error; k2 is the continuous functional of the fiber optic gyroscope error distribution. Note that the constraint parameters of the fiber optic gyroscope error are... using boundary constraints, By analyzing the error of the fiber optic gyroscope, the inertial characteristic quantity of the error measurement can be obtained... In this way, is it understandable?"

While talking, Chen Mo quickly wrote down concise words and formulas on the blackboard.After giving a rough explanation, he turned his head to look 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, at noon they had such a heated argument that they almost started fighting, and he was still talking about him behind his back, so he must know...

In this way, he also...

For a moment, Fang Quan felt that he was a bit out of place.

Supporting the index finger and thumb on the table, he unconsciously rubbed them for a long time, looked at Chen Mo and opened his mouth for a while.

"I...understood, thank you."

"Well, okay, let's continue... If you have any questions, you can ask them."

"Then what, I still have a question...how to optimize the measurement of these errors and integrate the errors?"

Fang Quan was the one who asked the question. His brain is really good. He is a bit hard to explain in terms of EQ, but he has nothing to say about IQ.Because he was the only person in the class who had some contact with Teacher Li before, and he was also the only person in the class who could keep up with Chen Mo's thinking.

Compared with the top students in other classes, he has the most doubts, but he can ask every question to the point.He was able to spare his face and ask Chen Mo one by one.

Chen Mo raised his eyebrows, but he didn't refuse. Fang Quan asked a link, and he explained a link.Hold the chalk and write the corresponding formulas and results on the blackboard.

……

"Using orthogonal functions to solve... When the FOG error parameter fusion feature quantity is expressed in the form of 6)x (t)=Ax(t)+Bu(t) and uc(t)=Kxc(t), then Get the closed-loop system... Combined with the automatic optimization method of the orthogonal function to solve the error of the fiber optic gyroscope adaptively, and obtain the sufficient condition of output stability...Use the global asymptotic stability analysis method to analyze the error characteristics of the fiber optic gyroscope and improve the error of the fiber optic gyroscope measurement accuracy."

"Ang! Great idea, why didn't I think of it! Then can I measure the error of adaptive optimization next!"

Fang Quan raised his hand and patted it suddenly, as if the roots of his hair were standing on end, he was very excited and happy. He spent nearly four and 10 minutes in the exam and couldn't do it, which made his whole brain knotted. , It was smoothed out so suddenly, Fang Quan felt indescribably comfortable and excited at this moment.

The happiest thing in the world is nothing more than that.

"Yep."

Chen Mo nodded affirmatively.

Fang Quan happily showed a bright smile. If he was not really awkward and embarrassed to let him go, he would have rushed up and hugged Chen Mo regardless of anything. This buddy is too powerful.

Really awesome.

He followed his train of thought completely, only to feel that kind of natural but incredible shock.

"The next step is the finishing work. Everyone has guessed it. It is to draw an error distribution map, and then get the analytical formula: x=Ax+Bu, y=Cx+Du, and then get the set of models... the fiber optic gyroscope Error feature solution x=[φ, ψ, P, r, v, ye]T, output u=[δa, δr].

Based on the above analysis, the optimization of the mathematical model for the error measurement of the fiber optic gyroscope is realized.OK, this question is over. "

When Chen Mo finished speaking, he poked the white chalk on the blackboard for the last time, ending the explanation of the whole topic.

"Teacher, I can go down." It was really difficult for him to talk about this class.

Finally he spoke.

Except for Fang Quan who was showing his front teeth and giggling excitedly, everyone in the classroom was very quiet at this moment.

Quietly looking at the blackboard.

At this time, in the lecture theater, there are four large blackboards, which occupy almost the entire wall area and are filled with white chalk.It is full of dense words and formulas, which can 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 the chalk writing was beautiful.But when they couldn't keep up in the middle, or after listening to the whole question, they looked at the words on the blackboard, and suddenly realized that this guy's writing speed is really terrifying.

TM, is this guy's hand flying on the blackboard?You obviously don't look too anxious?How come the blackboard is filled with writing in a blink of an eye.

Everyone looked at the densely packed words and formulas on the blackboard, and suddenly understood how this guy finished writing the paper in such a short period of time and handed it in ahead of time.

"teacher?"

"...Oh, oh okay, is this finished?"

Lu Ming suddenly came back to his senses, answered, looked up at the writing on the blackboard, and asked with complicated eyes.

"No, I can't write on the blackboard. I have expanded on my test paper, but it's not complete yet."
