Chapter Eighty-Eight: Definite Integrals

"Report to the instructor!" After Jiang Changshun and the others had planted the mines, they stood in the middle of the minefield and shouted to the instructors: "Our mines have been laid!" ”

The instructor walked near the minefield and observed for a moment, then nodded and said, "Not bad! It's not easy to be buried like this for the first time, but there are some areas that need to be improved, such as that one, and the footprints on the mines are a bit more drawn. It's too shallow, so that people can know that there is fraud at a glance. On the whole, it is not bad, and it is left to the comrades of the other group."

"Yes!" Jiang Changshun and the others responded, but their faces were full of mourning. Although they were praised by the instructors, they failed to "blow him up".

"It's your turn". Jiang Changshun and a few people walked out of the minefield in a huff, looking at me as if they were challenged, not believing that I had a way to "blow up" the instructor.

I smiled lightly, beckoned to Li Pinghe, and used a shovel to light a row of 'holes' at the edge of the minefield: "This, this, and this, all of them are planted with mines!" ”

"How can there be such a mine?" Lin Xue couldn't help but feel a little strange when she looked at it: "The mines are all scattered and buried, aren't they?" Comrade Cui, you bury it so regularly

"We'll know then!" I smiled, and Lin Xue, Jiang Changshun and others waved their shovels with suspicious eyes.

Although Li Pinghe didn't know what kind of 'medicine' I was selling in my gourd, he also knew that I had always had a lot of ideas, so he also started to do it.

After planting two mines, I realized that the instructor was really good. This kind of mine that relies on pressure explosion is actually very simple, and it is actually very easy to get it out if you don't step on it directly. It takes nine kilograms of pressure to explode, which means that you just need to find its location and dig it up from the side.

After burying a row of mines, and then covering the surface with camouflage, I cautiously walked a few steps inside, and found a mine in the minefield that Jiang Changshun had planted just now, and deliberately 'made' the camouflage on it, vaguely 'exposed' a little mine pressure plate, and even circled the surrounding soil a little, and it looked like there was a mine here at a glance.

Then he walked away a few steps, and in the suspicious eyes of everyone, he shouted at the instructor: "Report to the instructor!" Our mines have also been laid".

The instructor stepped forward a few steps and saw the mine I had tamed with, and couldn't help but point at the mine and scold: "Cui Wei, what the hell are you doing!" Has anyone 'made' the mines look like this? Are you on your first day in the army or,"

The voice stopped abruptly, and the instructor was stunned on the spot as if he had been immobilized, and then looked at his feet, and his face turned red.

It turned out that when he was pointing at the mine and cursing, he unconsciously took a few steps closer to the mine, and I dug a whole row of mines at the edge of the minefield, so that he could not step on it.

"Poof!" With a bang, I heard Lin Xue's unshruly laughter. But she quickly closed her mouth, not to mention the strange look of bitterness on her face. The other fighters were similar, even Jiang Changshun and his party were no exception.

"Instructor! Don't move, I'll help you! "At this moment, another soldier ran out, 'drawn' the dagger and was about to 'stick' it into the instructor's shoes.

"Go, go, go," the instructor pushed him and said angrily, "It's this foot."

With a coax, the students couldn't help laughing anymore.

Originally, I always thought that the classes I took in the military school should be all guns, cannons, or something, but in the afternoon, I realized that I was wrong. Because I found that the instructor wrote the words "definite integral" on the blackboard.

I read that right! I 'rubbed' my eyes, thinking that my eyes were 'dazzled', but it was true, it was indeed a definite integral,,

What is the use of the learned points of being a soldier?

Is it necessary to use it to calculate ballistics? Could it be that if you learn this thing, you will be able to shoot more accurately?

I turned my head to look around, and the students were all listening intently, and everyone except me seemed to think that this was normal. Except, of course, for the sad-faced country soldiers. But I think they're frowning because they don't understand what the instructor is saying, not because they want to know why they're learning this. But Jiang Changshun and the others listened to it with relish at this time.

Looking at me, I can't help but understand why the city soldiers look down on the country soldiers, it turns out that this is not only the reason for military quality, but also the reason for these cultural classes.

"Cui Wei, Cui Wei

"Here!" It took me a long time to realize that the instructor was calling me, so I hurriedly stood up and hurriedly scanned the blackboard, but I didn't know when the instructor had written a large list of symbols and numbers.

I can't help it, it's my hobby to get distracted in class!

"Cui Wei, where are your notes? The instructor pointed to the notebook on my desk that had not yet been opened, and said: "When you explained the mines last time, you said that the mines are buried in the ground so you can't see them, but this time you are talking about definite integrals, what other explanation do you have?" ”

"Poof!" With a sound, Lin Xue couldn't help laughing out loud.

Li Pinghe shook his head at me helplessly, while Jiang Changshun looked at me with some schadenfreude.

"Report to the instructor!" I scratched my head and replied, "The reason why I didn't take notes this time is because I thought it was too simple and there was nothing to remember."

There was a commotion, and the classroom suddenly 'chaotic'. Some people have disbelief in their eyes, others they have ridicule in their eyes.

"Hmm! Good! "Neither are the faculty; product, a powder rod on the blackboard to write the score number and a fraction. Asked... It's useless, solve this problem! It's good for the students to take a look! ”

"Report to the instructor!" I didn't even have to type a draft, and replied loudly: "The original formula is equal to 100 million coffee from one to one" is equal to a quarter of the mouth minus the negative quarter of the mouth, and the final answer is half of the mouth! ”

As soon as I said that, the whole classroom fell silent.

The original disbelief in the eyes has now turned into surprise and excitement, and the original ridicule has turned into shock. Lin Xue stared at me in surprise with a pair of big eyes.

Alas! Fortunately, I didn't return all the things I learned in college to my teachers, and I couldn't help but be glad to see this. It's also ashamed to say that when I was in college, that is, when I was about to take the exam, I only crammed for a few days, and I can only say that I have a rough skin and 'hair' for high mathematics. However, the instructor's questions were so simple that anyone who had studied the definite integral would know how to solve them, so I had to disappoint those who were waiting to see my jokes.

"One more question!" The instructor waved his hand and wrote a definite integral on the blackboard.

Alas! Isn't this the square difference and then opening the root number! I remember that I took a similar exam in the final exam, so I opened my mouth and said: "Ling" should be timely". with a mouth of half,"

A lot of it, it's actually a simple commutation, trigonometric functions plus a little bit of definite integral knowledge, I said, the instructor wrote on the blackboard at the same time, and finally came up with the answer is a quarter of the mouth. I was relieved to see this answer, and with my years of experience in guessing the answer, such a simple answer is usually not wrong.

Sure enough, the instructor nodded at me with a look of shock in his eyes, and there was a round of applause in the classroom. Li Pinghe pushed his glasses, and a pair of glasses behind the lenses looked at me in a daze, as if they wanted to see me through. Lin Xue applauded excitedly as if she had won a battle.

"When did you kid learn to set integrals?" After class, Li Pinghe immediately asked me.

"This," I hesitated, thought for a moment, and then replied, "haven't you seen my file?" Forgot that I went to study in the USSR? ”

"Oh!" That's what I said. Li Pinghe immediately remembered that when he interrogated me, there was indeed a clause in my file about going to study in the Soviet Union. So there was no doubt, only a wry smile said: "You guy, you know a lot of things!" I don't even know how you learned it! ”

I couldn't help but sigh when I heard this!

Dude! You don't know that we modern people have been reading since the age of four. From kindergarten to college graduation, the whole nineteen years have been accompanied by textbooks, do you think we can learn much?

"That's right, Mr. Li!" Thinking of the doubts and 'confusion' about this class, I couldn't help but ask Li Pinghe: "We are soldiers, what is the use of learning this fixed integral?" ”

"You don't even know that?" When Li Pinghe was asked by me, he couldn't help but reply with a look of surprise: "When ***, there is also a time when you use anti-aircraft artillery to hit enemy planes" Isn't advanced mathematics all basic? ”

"Hmm!" Listening to Li Pinghe's words, I understood that the infantry in the military academy also had the knowledge of artillery. But it's no wonder that our army has only had infantry all along, and military schools have only "foot schools", and they can only study in infantry schools.

"Classmate Cui!" Then Li Pinghe asked again: "You don't know what advanced mathematics is used for, so how did you learn it?" ”

I couldn't help but smile wryly, to be honest, I really don't know what most of the things I learned in modern times. Former people! It is to learn what is actually needed, but our modern people are a miscellaneous 'messy' to learn, and when they really go into society, they find that most of them are not used. This may be a failure of modern education.

After half an hour of lunch, it's time for a lunch break. Having regular meal times and rest times is a luxury for me. Because on the battlefield, we live a tense, chaotic, and irregular life almost every day. When the enemy comes up, he will '' and shoot as soon as he picks up, and when he is busy, he will naturally forget that he is hungry.

This is also understandable, I think that when I was in the college entrance examination, I would be so nervous that I couldn't eat or sleep well for two days. Now I lose my life at every turn, and every moment there are enemies and comrades on the battlefield in front of me, and sometimes I really forget to eat. Even if I'm hungry sometimes, I just grab a few handfuls of fried noodles and stuff them in my mouth. Therefore, many of the soldiers who came down from the battlefield had 'faulty' problems in their stomachs. It's just that these 'faults' are so insignificant compared to the wounded fighters that no one takes them to heart at all.

It was precisely because I couldn't eat and sleep peacefully on the battlefield that I felt that military school life was too easy. This is not? There is a half-hour meal time for each meal, and a lunch break of more than an hour at noon in addition to eight hours of sleep in the evenings every day".

After this kind of life has developed a law, if these soldiers are sent to the battlefield in the future, how can they still fight!

But then again, the leaders of the military academy seem to recognize this shortcoming. As a result, when the students were eating and sleeping, an emergency assembly suddenly came, and then something was arranged. Other students may still complain about this, but for people like Li Pinghe and I who came down from the battlefield, it was a piece of complete cake.

No, the whistle sounded, and Li Pinghe and I jumped off the 'bed' like a conditional counter-shot

Yes? I didn't hold the gun for a long time, and after a while I realized that it was not on the battlefield, but at the military academy! Just now, I seemed to dream that I was on the battlefield again.

I hurriedly tied my 'legs' and ran out, but I was still a step slower. I really wanted to say out loud to the instructor: "Report, the purpose of training soldiers in military academies is to send high-quality officers to the battlefield. But the volunteers on the Korean battlefield are not allowed to tie their 'legs'! The volunteers on the Korean battlefield, most of them don't wash their faces! Even going down the mountain to fetch water to drink has to risk your life, how can you still wash your face and feet."

But I knew that saying this wouldn't do anything other than being a batch, so I just kept my mouth shut.

"Announce the mission now!" The instructor shouted at us hoarsely, "Work in pairs, reach the designated location on the map as fast as possible to retrieve the whisper!" ”

I have heard of this task, and Li Pinghe, who has a wealth of experience, because he was worried that I would have a "situation" in the future training, had already clearly explained to me the 1510 possible unexpected tasks in the military academy.

The trainees called this ding, and the task was "to find a point." The aim is to help students learn to read a map and quickly follow the markers on the map to find the designated location. The instructors will put a file on the designated map in advance, a small note, or something!

Not to mention, this skill is still very important to the students. After all, the cadets will all go out in the future to be petty officers in the army, and if they don't know how to look at the map, they won't "look for points." Or if you don't find a point quickly enough, it's likely that you will be able to pull a team all over the mountain and run around and not find the right attack, and in serious cases, it may affect the entire battle.

But "I never dared to let people know that I was road blind!" On the battlefield, you can also use the guide Wu is the soldiers who are familiar with the terrain to pass the level.

Looking at Li Pinghe standing beside me, I couldn't help but breathe a sigh of relief. Li Pinghe has long had the experience of studying at a military academy, and it is not a trivial matter to complete this task with him in a group. But who wants the instructor to send a map to Lin Xue on the other side of me, Lin Xue waved the map in his hand at me, and said excitedly: "Classmate Cui, let's be in a group, I'm relieved to be with you, we promise to take the first place!" ”

As he spoke, he grabbed me and ran. It just made me smile wryly. Looking back at Li Pinghe, Li Pinghe had no choice but to smile helplessly.

"Captain!"

"Didn't I tell you? Don't call Captain Cui, it's Classmate Cui! I reminded.

"There's no one else now, is there?" As soon as Lin Xue ran out of the military academy, she was like a bird in flight, talking and jumping all the way, and sometimes stretching out her hand to turn in circles. Where it looks like it's on a mission.

"Call it whatever you want!" I didn't bother to argue with her, so I picked up the map and looked at it while I was running on the road.

"Commander Cui, I heard my brother say that you are a famous sharpshooter in the army, right?" Lin Xue didn't seem to be in a hurry about her task at all, and kept talking like a machine gun while walking: "I know my brother's marksmanship, and he is also a sharpshooter." And it's very proud, usually no one is convinced, but when you talk about it, you admire it convincingly. When can I show me your marksmanship? And ah! I've heard you've also seized the one that can see things at night, night vision devices! Can that thing really see things at night? I want to see it too."

The curiosity of the 'girl' family! Listening to me, I couldn't help but hate in my heart. Lin Xue muttered in my ear, so that I couldn't find the direction of the location marked on the map. But then again, even if she wasn't talking next to me, I couldn't seem to find it. No, I took the map and flipped it upside down with the surrounding environment several times, and it didn't seem to be the same.

"Captain Cui". Although I didn't answer, Lin Xue still asked unrelentingly beside her: "I also heard my brother say that there is a North Korean 'female' soldier who is interesting to you and has been looking for you several times, is it true?" How did you meet? ”

"What?" Hearing this, I suddenly raised my head from the map, looked at Lin Xue and said, "What did you just say?" ”

I didn't say anything. Only then did Lin Xue realize that she had slipped her mouth, and ran away as soon as she pulled out her 'legs'.

But after running for a while, she realized that I was not chasing her, and she turned back to her in confusion and shouted, "Hey, do you want to complete the task!" The goal is "small" over here

Reluctantly, I walked up and asked, "Tell me what's going on, I heard it clearly just now!" Did Jin Qiulian come to the army to look for me? How did I not know? ”

Lin Xue pouted aggrievedly and said: "You don't know the discipline of the troops, we can't have anything to do with the North Korean 'women', my brother said that this is a matter of style,"

"So your brother told her I wasn't there, was he?" I can't help but be a little annoyed when I hear this, this is also a style problem! What age is this", but it seems that there is really a style problem in this era!

"If you're looking for it, look for it now! What's the big deal". Unexpectedly, Lin Xue also lost her temper, and ran towards the mountains and forests without looking back as soon as she turned around.

"Hey! How have I sinned against you?" I was a little inexplicable, and then I saw Lin Xue running towards the mountain road alone, worried that something would happen to her 'girl' family, so I followed closely behind.

In fact, "the real reason why I followed is a little difficult to say, I am afraid of 'getting lost'"
