The daily life of the science master's book-wearing group

Chapter 439 Calculus

After an exam, when the candidates walked out of the tribute courtyard, most of them bowed their heads and remained silent.

The unexpected agronomy topic seemed to hit everyone's heart with a hammer.

Some people feel flustered, dazed, and even angry. They don't understand the significance of the examiner writing such questions.No one in this world has ever taught them these things. After exhausting the four books and five classics, or agricultural classics, it is difficult to find the answer.

This question is not about knowledge, but about heart.

A person who is determined to bring peace to everything will always have some ideas.

This cruel and utilitarian world needs idealists.

Song Qingyue stood on the fourth floor of Liuquanju holding Li Kun in her arms, watching the people coming and going downstairs with a slight smile on her lips.I thought to myself, if the father-in-law and Li Zhao knew, one day, the decadent system would not be able to bear the rapid development of productivity, the new trend of thought would overwhelm this dynasty, and the end of the royal family might be on the guillotine. I don’t know if they would regret it reform today.

But the road is still long, she kissed her son's cheek, and hooked the corners of her lips nonchalantly.

……

After all, they are all masters. Even if they face a problem and their minds go blank, they can still write a beautiful article.

The students went home with mixed feelings and anxiety to take a shower and rest, and there was the last math class the next day!

In addition to the candidates who took the exam this year, there are also the two hundred or so candidates who were sentenced to fail the math test last year!

These people worked hard and studied hard for a whole year.

There are a few candidates who didn't take the exam because of mathematics last year, regretting it so much that their intestines are green!
I knew that I only needed to make up a math test, and they took it for reference last year.

To save this year's exam, I have to take those agronomy questions again.

Those candidates who failed Enke Mathematics last year were even more fortunate!I thought I was unlucky that year, but I didn't expect this year to be even more unlucky.Last year's exam, although he failed in mathematics, he got a place to enter the Academy of Sciences, and he could study with the best math teacher in the whole week——His Royal Highness the First Prince.

Isn't it better than those who think about it at home?

Studying mathematics in Guozijian for a year, after all, you will achieve some success, right?
But soon, they stopped laughing.

When they got the test paper, they were shocked to find that the questions on the test paper were more than one level more difficult than last year.

This is like a classmate who is used to taking national exams on weekdays. When he suddenly found out that he took the Jiangsu exam during the college entrance examination, he felt like crying on the spot.

Song Qingyue didn't want to tire herself out, so she only participated in setting the questions, not in correcting them, so this time there were three more deputy chief examiners in mathematics, except for the two original Ph. Xiao Jinrong, and Jiang Yuanchao, who won the second prize in the mathematics competition.

However, they are not responsible for producing papers, only for correcting.

The answers were all prepared by Song Qingyue in advance. The last question of this year is still an integral question. I want to find out if there is a genius in this time and space to make it, so this question still has no answer.

The examiners turned to scratch their cheeks and bite their pens outside, and several examiners were also silently doing questions inside the curtain.

Li Zhao had already tried it before the wife left with her son, and now she is staring at the last integral question and thinking hard.

He repeatedly drew the line of the primary function on the paper, looked at the triangular area under the line, and knew in his heart how to ask for the area of ​​this area, but once it rose to the secondary, the area could not be calculated.

But from zero to one, and from one to two, there must be some kind of law and connection between them.

Dimly in my mind, I have actually found a little way, but it is covered with a layer of paper, and I don't know how to pierce it.

Everyone here was thinking about the last question on the second day.

But still until the end of the exam, the six of them still haven't figured out a solution.

Such a result was not unexpected. Several people looked at Li Zhao, and Li Zhao also helplessly spread his hands.He didn't want to ask Song Qingyue, and Song Qingyue could bear it, and never told him the method of calculus.

But at this moment, Li Zhao suddenly had a flash of inspiration: Derivative!

Will it be a derivative?

He waved his hand and immediately asked Lin Wanfu to bring more draft paper.

"Your Highness..."

Jiang Yuanchao wanted to remind Li Zhao that when the time came, he would announce that he would stop writing and closing the volume, but Li Zhao waved his hand without even raising his head, and asked Jiang Yuanchao to do it: "Don't make noise, I seem to have thought of it."

Jiang Yuanchao had no choice but to announce the end of the exam instead of Li Zhao.

Li Zhao scribbled hard on the draft paper, calculated the result with his own guess, and then used a very clumsy method to divide the area under the quadratic function to try to calculate an estimate. It was indeed very similar to the calculated result!

"Ha! Haha! It really is like this!" Li Zhao was so excited that he wished he could go home and show off to his wife right now.

But there is still a problem here, even if he knows the method, he hasn't deduced the process yet.

But mathematics is such a magical thing. In many cases, with a beginning and a result, the middle derivation process is easy to follow.

Li Zhao looked up at the result and laughed.

Xiao Jinrong asked itchingly from the side: "Your Highness, have you figured it out?"

Li Zhao raised his eyebrows tremblingly, looked at the five deputy examiners, and asked, "Do you think about it yourself, or can I talk to you sometime?"

The five of them were a little depressed, eager to know the answer, but unwilling.

Hesitation, contradiction, entanglement!
Never mind, let's change the test paper first!

The five people were very unified and no one said a word, and they all lowered their heads to correct the test papers.

Li Zhao walked slowly to his stack of test papers, and began to correct the test papers in a good mood.

Five days later, after ensuring that each paper was checked three times by different main examiners, the results finally came out.

Li Zhao quickly ran home to report the "great news" to his wife.

"Look, you just say it's bullshit!"

A certain person is frightened with his arms akimbo.

Seeing the derivation process, Song Qingyue raised her eyebrows high, then frowned and clicked her tongue, as if very dissatisfied.

"Why, is there a problem?" Li Zhao immediately became nervous, "Impossible! I have thought about it several times, and this derivation is definitely not a problem."

"It's no problem!" Song Qingyue pulled the agitated Gouzi to sit down, "I just think it's a pity."

"What a pity?" Li Zhao stared.

Song Qingyue sighed: "Why do you think our Dazhou has no other geniuses except you?"

Look, is this a human language?

This was supposed to be a day of great celebration, but my wife sighed because no one else solved this problem first!
Li Zhao was so angry that he almost vomited blood!

He picked up the slender beauty, put it on the table, and pressed it down.

Song Qingyue, you owe a lesson!

……

An hour later, Song Qingyue sat lazily in Li Zhao's arms, playing with Li Zhao's hair while laughing happily.

Li Zhao was still groaning in anger!This woman is so annoying!
-
The marking speed of the first three subjects is always slower than that of mathematics.

The answers to the three questions about agriculture do not have to be written in the stereotyped form, so there are any forms.

Some people are full of sage's words, and some are as gorgeous as dragons and phoenixes, but no matter how beautiful the article is, as long as there is nothing to say, the final score will be changed into a small black fork by the chief examiner, Mr. Lu Cifu.

The emperor attached great importance to this imperial examination. After the results of the examination were obtained, he asked to check the papers himself. It didn’t matter how he answered the previous questions. He just wanted to see how these eunuchs who had learned the principles of sages since childhood answered the three questions about agriculture. of.

So the examiners handed in about [-] test papers that were barely worthwhile, so as not to make Nine-Five Supreme Master angry.

……

Every time the rankings are released, there is always a lot of people outside the Gongyuan, which is extremely lively.

Li Zhao and Song Qingyue's carriage had to take a detour to avoid the crowd.

Both of them were called into the palace to read the test papers with the emperor. Song Qingyue lifted the curtain of the car and looked at the bustling street with a smile on her face.

"Shiro didn't participate this year. What does it have to do with you, so happy?"

Song Qingyue laughed loudly: "Seeing that I have so many talented people in the Zhou Dynasty, I am happy for my father and Your Highness... Ah! Why are you pinching my face?"

"Speak well!" Li Zhao pinched her cheek and stared.

"I just remembered the scene when the eldest brother and the second brother were on the list a few years ago, so please be happy." Song Qingyue grinned, "Aren't you still unhappy because of what happened a few days ago?"

Li Zhao clicked his tongue and let go of his hand a little depressed.

Song Qingyue immediately went up to him and kissed him: "Brother Ah Zhao is amazing, really, Yue'er admires you so much! Look at my sincere eyes, brother!"

Li Zhao rolled his eyes and pulled Song Qingyue's little head away in annoyance.

Song Qingyue leaned over to coax the awkward dog man again, leaned into his arms and said softly: "To be honest, I taught you the concept of derivatives before, and no one else can compare to you in this regard. You can do it There is also a reason for this, right? If I hadn't taught you the derivative before, would my husband still have the confidence to deduce it so quickly?"

Li Zhao was silent.

It seems that it is really difficult.

"The limit thinking here is similar to the method of cutting circles. Since you can figure out how to calculate pi, you should be able to slowly think of the derivation process of the calculus formula. I just want to see if there is a genius in Dazhou. "Song Qingyue said slowly, and sighed again: "There are still too few talents in science and engineering."

This time it was Li Zhao's turn to put his arms around Song Qingyue's shoulders to comfort her: "Don't worry, in another five years, the whole big week will be different."

　There's another one tonight
