Chapter 270: Higher-Order Homogeneous Differential Equation Solutions and the Growth of Their Small Functions (Part 4)

After the opening ceremony in the morning, there was another session of heat and a session of mechanics in the afternoon.

In a science subject like physics, in the stage of theoretical learning, it is often necessary to consolidate knowledge by doing questions.

Therefore, after a few classes during this time, the students are almost either doing the questions or on the way to brush the questions.

Everyone is on the same starting line, and everyone doesn't want to be left behind.

The students who can come to this class have more or less experienced the leader advantage.

Good grades, get rewarded and praised, then increase interest, and finally form a positive feedback loop. So, most of the students did their best.

Except for Su Mu.

Because Su Mu's homework has already been completed.

Many parts of physics and mathematics are interconnected, and Su Mu had brushed a lot of advanced questions about college physics in the physics competition before, so the course at this stage does not have any pressure on him, and it can even be said to be a little simple.

The basic topics in these textbooks are not comparable to the homogeneous differential equations he is currently studying.

Just one "class of high-order homogeneous differential equation solutions and the growth of their small functions", the time it takes Su Mu to understand can be worth half of the physics textbook.

Su Mu's recent achievement is to figure out that "when there is a dominant role in the sense that a certain coefficient has a faster growth than other coefficients, the solution of a homogeneous linear differential equation can be obtained, and the convergence index and the second-order convergence index of the point of the small function can be obtained".

Among them, the "convergence index and secondary convergence index" are very troublesome, but Su Mu has also overcome them today.

Therefore, Su Mu now usually goes to the library alone at seven or eight o'clock in the evening to continue studying mathematics.

Only when bottlenecks are encountered.

Or when you're bored and relaxed.

Only then will I take out the professional teaching materials and take a look at them, relax and relax.

......

".... This Gu Tunan is too much. ”

On Thursday night, Su Mu finished his day's study, took a shower and was about to lie on the bed to code the word update, when he heard Zhuge Chuixue shouting into the dormitory.

Shen Tianhao was not in the dormitory.

Lin Shaojun was writing his homework, and he was also attracted by Zhuge Blowing Snow's words.

"What's wrong?"

Su Mu put down his phone and asked, "Why did he offend you again?" ”

may be because Gu Tunan always approaches Zhen Qiqi without a match, and Zhuge Blowing Snow's attitude towards him has never been very good, but this is the first time Su Mu has heard Zhuge Blowing Snow say the word "damn".

"That Gu Tunan sent a canvassing message to many boys in our class, asking them to vote for him as class president when the class meeting is held tomorrow." Zhuge Blowing Snow said with some resentment.

"Huh?" Su Mu was slightly stunned. I didn't expect Zhuge Chuixue to say something about the squad leader.

He has been concentrating on number theory for the past two days, and he has forgotten about running for class president.

"This should be normal, if you want to run for class president, canvassing is for sure." Su Mu shrugged his shoulders and replied.

"And, how do you know he's canvassing? It's not like you're trying to do something like that. ”

Su Mu was a little curious, because since Zhuge Chuixue was going to nominate Su Mu as the squad leader that day, he had been preparing something.

If Su Mu guessed correctly, Zhuge Chuixue should also be ready to help him canvass for votes.

"I...."

Sure enough, Zhuge Chuixue was asked by Su Mu, and immediately stammered a little.

His previous idea was indeed to help Su Mu canvass for votes, but he was just going to visit every dormitory.

Unexpectedly, Gu Tunan did more than him, and he sent a message to every classmate.

"That's different, Gu Tunan is not only canvassing for votes, but also promised to invite his classmates to dinner if he succeeds in becoming a class leader."

"That's pretty good, but the most infuriating thing is that he didn't even send a message to our dorm, just separated us."

Zhuge Chuixue still had a sense of resentment on his face.

“......”

Su Mu was stunned, he didn't expect that it was just a small squad leader election, and Gu Tunan could actually make it so magnificent.

"He... He messaged me. ”

Lin Shaojun on the side hesitated, rarely made his own voice, and said a little shyly:

"But what he probably didn't know was that we were in the same dormitory.

Lin Shaojun usually has very few words and a low sense of existence, but at this time he still provided his own information.

"Didn't send it to me anyway."

Zhuge Fuxue pouted.

"Faun, he's giving us a war letter."

"Well, there's no need, it's just a squad leader."

Su Mu couldn't laugh or cry a little, Zhuge Chuixue's expression on his face.

It's like going out to war.

"If he wants to be a squad leader, let him be a squad leader, there are a lot of things to do as a squad leader, I just want to study hard now."

"If there is any conflict in the class because of something like this, it will not be good."

Su Mu opened his mouth to persuade.

To be honest, Su Mu was also a little speechless.

At first, he just thought it was a small campaign speech, but he didn't expect that now it has been a part of canvassing, and if it goes up a little further, wouldn't it be like a campaign speech from the United States?

It's just about thirty people, and it's really unnecessary.

If he had this time to accompany Gu Tu Nan to play this kind of child's trick, he might as well accompany Yan Xiaoke more.

"Alas, Faun, you're just too good-tempered."

Zhuge Fuxue sighed.

However, the turn of his head was a little more determined.

"It's okay, you study hard, I'll fight him in this matter! The Eye of the Evil King cannot be subdued! ”

"The Evil King's Eye?? Do you want to fall in love with the second disease? ”

Su Mu's eyes widened, he originally thought that Zhuge Chuixue was just a secondary two, but he didn't expect that he was really a fan of Liuhua.

The second disease also has to fall in love, which is a very popular anime a few years ago. The hero and heroine in it are deep middle two patients, but I didn't expect Zhuge Chuixue to inherit such a character perfectly.

“....”

Zhuge Blowing Snow's voice stopped abruptly, and he realized that he had slipped his mouth.

"Faun, you have also seen the second illness and want to fall in love?"

Zhuge Fuxue asked a little excitedly.

"Hmm."

Su Mu nodded:

"It's pretty good."

"Forget it, you can go ahead."

Su Mu decided not to disturb Zhuge Blowing Snow's nature.

This kind of child, when he grows up, sooner or later will find the shame he has now.

Thinking like this, Zhuge Chuixue has always called himself the god of faun, but it looks so natural.

"Although Gu Tunan has sent a lot of messages on the boys' side, everyone's response is not very big, and the main people who support him are the people who have participated in the Olympiad training team together before."

"Gu Tunan's popularity on the girl's side seems to be very high, I'm not too embarrassed to talk to the girl, so I can only learn that he also sent a few messages." Zhuge Fuxue explained.

"But don't worry, Faun, we still have a chance! I have already asked others, Gu Tunan has a big disadvantage, that is, he is not a resident student of our school, it seems that he rents a house in the teacher's apartment in the back after applying, which will give us a greater advantage. ”

"I'm trying to win over some more people tonight, we can't lose momentum no matter what we say, I don't need you to go out, I can do it alone."

Zhuge Chuixue seemed to think of something in his eyes, and after chatting with Su Mu for a few words, he ran out again, leaving Su Mu with a messy face.
