There really are no eternal holidays, only eternal exams.

Ye Gui, who returned to 97 a few days ago, didn't expect that his first exam back in high school would come so without warning, of course, this without warning was just for him, Jing Xiandong next to him began to prepare for this exam as early as the weekend, and when Liao Zhichen was dangling next to him in front, Jing Xiandong was desperately attacking mathematical formulas, striving not to be trained too badly by Old Lady Long after the exam.

As for the rest of the people, it was purely their own selective forgetfulness, Ye Gui looked at Liao Zhichen, who was sitting in front of him in front of him in front of him, scratching his ears and cheeks, and heard Jing Xiandong say that he had notified him of the test last week, and he hadn't mentioned a word about it in the past few days, and Ye Gui himself didn't know anything about it.

After a while, a man in his forties dressed in ordinary clothes walked in with a pile of rolls. The man entered the classroom and stood on the podium and placed the paper on the lectern.

"Put the book away.,I said it before this exam.,It's the last math test in the grade before the bottom exam.,It will be used as the basis for each class teacher to check and fill in the gaps for students in front of the mold.,Of course, the leaks are mainly for the key classes.,Just fill in the gaps for you.,Because some of the questions are more difficult this time.,I guess you can't do it.。

It was Ye Gui's math teacher Long Liyan who spoke, and Wei Suxin, Ye Gui's former homeroom teacher who was sick and resting before, and called them two of the four evil stars in the parallel class. Long Liyan is full of confidence in training people, and always stands at the height of morality and age, so he is called Mrs. Long by the people in Ye Gui's class. Thinking about it, Ye Gui's class is also unlucky, there are more than a dozen parallel classes, and their class occupies half of the four evil stars.

In the previous life, many people in Ye Gui's class were educated by Long Liyan and Wei Suxin, and goods like Liao Zhichen had long been numb, which can be seen from the fact that a kid looked at death as if he were going to take the test as soon as he heard about it. Liao Zhichen didn't forget about it, but he had to be scolded if he reviewed, and he had to be scolded if he didn't review, so why didn't he choose not to review, he still had dreams, in case he wasn't scolded.

Ye Gui sighed secretly, he was really drunk, why didn't he turn the old lady into a beautiful teacher

Old Lady Long looked at the silent students under the podium, and then said: "Of course, don't be afraid, my requirements for you will not be as high as the key class, and there are some big problems that cannot be done in the future, so I will not care about it this time." Saying that, Old Lady Long's tone changed, and her voice became heavier: "But! This time, if anyone can't do the basic questions in front of me or is full of mistakes, which makes me lose face in the teaching group, then don't blame me for turning his face and not recognizing people. Okay, now send out the papers, start the exam, and finish the two classes. ”

The classmates in the first row took the paper from the old lady Long's hand and then separated and passed it back in turn, and after a while, it was passed to the back, Ye Gui took the paper and looked at it, most of the first side was very familiar, only a few questions may seem a little complicated, but it is nothing more than a matter of calculation. Turning the test paper over, Ye Gui paused for a while, the difficulty of this set of papers from the back of the question began to mutate at the speed of a kind of biological mutation that has been irradiated, from the first answer question above is only slightly higher than the ordinary difficulty, to the last question of the second question There is already a lot of calculation, and the last three questions are more difficult than the other, and the last question is completely the difficulty of the Olympiad questions.

Ye Gui couldn't help but begin to sympathize with Liao Zhichen, this set of papers is the legendary "suppression paper", in order to avoid students from being complacent or lacking motivation when reviewing, the school will first arrange difficult test papers when reviewing in the third year of high school, and then the difficulty will slowly decrease, knowing that a simple set of test papers will be used to stabilize the confidence of students before the final college entrance examination.

This is also the most important reason why the first mock test, the first mock exam is the most difficult, and it can best detect the true level of students, so the first mock exam is also called the "one touch" exam, and the importance of this exam and the last two mock exams, especially the three modes, cannot be compared.

And the test paper in front of him is the simulated "suppression paper" before the formal "suppression paper", Ye Gui seems to have seen the key classes that are like hell after the results, different from the parallel classes that usually break the jar and break, for the students who score 120 or even 135 points or more in the college entrance examination mathematics goal, this is the last whip of the school's mathematics teaching and research team before the college entrance examination.

However, these questions don't seem to be difficult for Ye Gui.

As the only hidden boss present who had learned high numbers, Ye Gui smiled.

When I was in high school, I heard that there were fierce people in the key class who could use calculus to complete the analytic geometry problems in half an hour, and now I finally know, it turns out that this feeling is so cool.

Especially the last finale proof question, isn't this a comprehensive application of the differential median theorem and series convergence, Ge Jun Ge Ma Cheng doesn't deceive me!

Ye Gui put down the paper after reading it, calmed down for more than a minute, and saw that the classmates in the classroom had already begun to fight hard, put out the test papers and scratch paper, and began to answer the questions.

Brush Brush Brush ......

In later generations, Ye Gui was not like other students who were messing around in college, and he never let go of his undergraduate and graduate studies in mathematics. The environment is compelling, in fact, if you change people who are inseparable from mathematics for further education and research, then mathematics will definitely be as good as Ye Gui. The three courses of advanced mathematics, discrete mathematics, and probability and statistics are the most frequently used by Ye Gui, which is different from simply mastering theoretical knowledge, Ye Gui has already integrated the knowledge commonly used in these courses in that period of time.

At this time, Ye Gui's pen was like a divine help, and there were almost no jams in the multiple-choice questions and fill-in-the-blank questions in the paper, especially a few questions with a large amount of calculation, Ye Gui directly used the knowledge of high mathematics, just like having a God's perspective, and the answer was calculated in a few strokes.

Crash

Ye Gui flipped over the paper and began to do a big question, Jing Xiandong glanced at Ye Gui in surprise, and Liao Zhichen also subconsciously looked back at Ye Gui, but this kid naturally attracted the hatred of the teacher.

"Liao Zhichen, what are you doing, do your best." Long Liyan, who was sitting on the podium invigilating, called Liao Zhichen, and then looked at Ye Gui again.

Ye Gui ignored everything that was happening around him, he was completely immersed in this set of test questions, and the answers with aesthetic sense were written in Ye Gui's pen step by step.

If there is a mobile invigilator at this time, you will find that the entire third-year high school students have encountered different obstacles because of this set of questions, and Tian Baijun is frowning and calculating the last multiple-choice question; Cui Jianyu just turned around and made up for a multiple-choice question that he had skipped earlier, and then looked up to wipe his sweat, but saw that the cold girl sitting in front of him had already done half of the fill-in-the-blank question, so he hurriedly lowered his head and worked hard to write.

People are more popular than people, just now, Ye Gui, who has never heard of playing musical instruments like soy sauce, entered the door and abused Lu Haoming, one of the people who carried the handle in the music room, and met a person who was ready to go abroad without the college entrance examination but made such a difficult math paper, it is simply unreasonable, can't the world give a kind person like me a way to live?

And Liao Zhichen pursed his lips, secretly scolded Mrs. Long for being really sharp-eyed, and then looked at the fifth multiple-choice question bitterly, how can this question be calculated without an answer, alas, no matter, choose C.

The more Ye Gui wrote, the more fluent he became, the number series limit operation criterion, the equivalent infinitesimal substitution theorem, the zero point theorem, differential calculations, all kinds of knowledge that he had mastered kept emerging from his mind in the calculation, he was like a lonely rider galloping alone in the vast desert, the faster he was, the more excited he felt in his heart, and then ran more hard into the distance.

Ye Gui went all the way unimpeded, and Ku Ding solved the last question like a cow, the difficulty of this question was much more difficult than the test papers he had done before, but because of this, there was the easiest solution in the advanced skills.

If the function has a derivative up to the n+1 order in the open interval, then when the function is in this interval, it can be expanded into the sum of a polynomial and a remainder, which is the knowledge of the differential median value theorem.

The next step is to combine the principle of series convergence, Ye Gui wrote the McLaughlin remainder term in Taylor's formula, and then used the concept of series convergence to find the remainder term, and the answer appeared.

Drawing the last drawing in a chic manner, the whole set of rolls was sprinkled in less than an hour to answer, Ye Gui put down the pen and paper and looked out the window.

used to be a low hand, but now he also tastes the feeling of loneliness.
