Qin Chao's eyes slowly opened, and a trace of emotion appeared on his face: "Over the years, my main focus has not been on natural science, but there are still some people who occasionally take the time to study, these questions are very good, very classic, very good, and very difficult." ”

"Qin Gongzi, these questions are naturally difficult for others, but for Qin Gongzi, he must disdain them. Zu Shengcai said loudly, "Qin Gongzi, I think you really want to do it, you can give the answer with a wave of your hand!"

Waving his hand to give the answer, everyone had a calm face, and the ancestor was obviously roasting Qin Xian Ao on the fire.

Mr. Zu Shengcai laughed, Mr. Han said very well before, we are all human beings, not gods, even if God comes, it is impossible to give answers to these questions with a wave of his hand. Qin Chao smiled and said, "That's it, a year later, today, I will give you all the answers." ”

"A year from now?"

Zu Shengcai looked up to the sky and laughed like thunder.

"It turns out that this is the so-called No. 1 wise man in the world, I have seen it, I have seen it, Shanlan, Akid, friends of the Heavenly Domain Gate, we are wrong, we are indeed wrong, we are too confident in Qin Gongzi, I can't think of it, I can't think of it! I just don't know how Duan Gongzi is!" Zu Shengcai's yin and yang strange voice sounded, and some people from the Heavenly Domain Gate also connected their mouths, saying all kinds of sarcastic words.

"Giggle!" a string of laughter rang out like silver bells.

"Qin Niangzi?"

One by one, they looked at Qin Ning who was smiling and trembling, and Qin Dynasty also looked at Qin Ning suspiciously, this kind of banquet is not allowed for women like Qin Ning to be at the table in this era, but Qin Ning has to come, and the Qin Dynasty naturally has no choice, and in his bones, the Qin Dynasty does not recognize that women cannot go to the table, so Qin Ning said that he wanted to come, and the Qin Dynasty did not object. I just brought her with me.

Everyone has the impression that Qin Xianao is anti-Confucian, anti-Confucius, and even anti-Zhuzi Baijia's 'devil', how can he take vulgar etiquette in his eyes, so Qin Xianao brought his daughter, and no one dared to say it. Or people like Cheng Yi and Sima Guang know that it is useless to say it, so it is better not to say it at all, so as not to be unhappy.

"Qin Niangzi, why are you laughing?" Su Shi asked in a loud voice.

"It's nothing, it's just laughing at some people who don't know the sky. Qin Ning said crisply, "My husband's ability is well known to the world, even after millions of years, no one can erase it." Some people have made some inconsistencies and laughed at them here, but they have become clowns, how can I not laugh?"

Zu Shengcai's face sank: "Qin Niangzi, I didn't deny Qin Gongzi's talent and merits, but I admired it so much that I thought that these questions couldn't help Qin Gongzi, but Qin Gongzi actually ...... It's so disappointing. What's so funny about that?"

"Hmph, do you really think that these questions can be difficult for my husband?" Qin Ning said crisply.

"I also think it's hard to stop Qin Gongzi. But the fact is that Qin Gongzi said that he would not be able to give an answer until next year. Zu Shengcai said with a smile.

"My husband said that he will give the answer next year, which is to save face for you and all the adults here. Qin Ning said triumphantly.

Zu Shengcai couldn't cry or laugh, and he couldn't cry or laugh one by one.

"What?" Qin Ning's face sank, "You don't believe it?"

"Letter, haha. Nature is faithful. Zu Shengcai laughed, and no one could hear the irony. Cheng Yi, Sima Guang, Wang Anshi and others also shook their heads secretly, what kind of concubine did this Qin Xianao bring, and he didn't know the height of the sky at all.

Su Shi raised his eyebrows.

"Qin Niangzi, are your previous words true?" Su Shi knew that the knowledge of the Qin Dynasty was unfathomable. What is taken out is always only a part, others don't believe Qin Ning, but he believes it somewhat.

"There can still be fakes!" Qin Ning snorted.

A table in the distance Gongsun Dapeng's heart moved at this time, as Qin Ning's master, he naturally knew that Qin Ning was by no means pretty, and his mind was full of straw vases.

"Ning'er, could it be that Gongzi Qin really gave an answer easily?" Gongsun Dapeng asked in a loud voice.

Qin Ning looked at Qin Chao: "Xianggong, you can open everyone's eyes and solve these children's questions." ”

"Ning'er. Qin Chao turned a tiger face, "For a moment, where will I do it." ”

"You won't?" Qin Ning chuckled, laughing like a fox who had to calculate, "Hmph, don't think I don't understand, what you wrote in the study, I peeked at every word, although there are too many that I can't understand, but the solution to these questions, I really see the solution from your manuscript paper, if you push back and block, it's better for me to solve it." ”

Quiet!

There was silence all around.

Wang Anshi looked at the Qin Dynasty: "Young Master Qin, what ****** said is it true?"

"This ......" Qin Dynasty glared at Qin Ning fiercely, and the women liked to pass on the draft paper of the Qin Dynasty, especially Xian Yuting, Bai Run'er, Pian Miaoyu, Jun Yueru, Qin Ning, Guo Yuanyuan is the most, the Qin Dynasty doesn't know, but he doesn't care, and the draft is a draft after all, which is convenient for the Qin Dynasty to use for its own calculations, so what is written on the draft is always fragmented and scattered, what is obtained in the brain, there are no three out of ten on the paper, the Qin Dynasty is not afraid that everyone will see the secret, and what if they see it, the Qin Dynasty does not have much to hide in front of the family, it is nothing more than exposing some strength in advance.

It's just that Qin Chao couldn't imagine that some of the mathematical drafts he wrote in later generations would actually be understood by Qin Ning, and they were studied quite well.

"Pen, ink, paper, inkstone, four treasures of the study. Qin Chao spoke loudly. As soon as these words came out, many people became excited.

"Quick, go to the study and get pen, ink, paper, and inkstone. Zu Riheng shouted to the servant, Qin Chao's words undoubtedly admitted everything Qin Ning said, although Zu Riheng was very suspicious in his heart, these problems Qin Xianao can really solve, but at this time, what else can he do except take pen and paper to let Qin Dynasty solve it. "Yes!" said the servant, striding toward the study.

"Qin Gongzi really has the answer a long time ago?"

"Who knows, but if he doesn't do it, his wife will do it himself, and he is now chasing ducks to the shelves, and he has to solve it. ”

"But his wife will never harm him, these questions are difficult for us to climb to the sky, but Qin Gongzi may really be a children's question. ”

"Of course, his wife will not harm him for no reason, but such a difficult question, do you really think he can easily solve it?" There was a buzz all around, and soon the servant brought the empty table and prepared the pen, ink, paper, and inkstone. "Mr. Qin, I'll polish the ink for you. Zu Riheng stepped forward and quickly sharpened the ink, and the Qin Dynasty lifted the pen and dipped the ink, and the pen moved like flying.

Everyone stepped forward to watch, only to see the Qin Dynasty pen falling, one by one the brush words appeared, the words have a fairy spirit, the pen is like a swimming dragon, especially the Qin Dynasty pen is like the wind, slightly drunk to write in the grass, when the pen is really like the wind, the words are like alive, to turn around and fly off the paper.

One by one, their eyes lit up, and then they looked at the solution on the paper, but it was:

"There is a curve f(x,y)=0, and if you want to find the tangent at the point P above it, consider a 'arbitrarily small arc' PQ, which is caused by the increment QR=e, and PQR we can imagine as ......"

It is not difficult for those who will know, but it will not be difficult for those who are difficult, once a knowledge point is really solved, sometimes it is very simple, I saw Qin Chao stroke down, put the pen down in an instant, and said lightly: "This is the answer to the first question." ”

"Is this the answer to the first question?" glared one by one, and then even thought about it.

No one noticed that Zu Riheng's eyes were like copper bells at this time, and then a blush of excitement flashed on his face.

Under the porch of the west side sat three tables, all of which were the bigwigs of the Tianyu Gate.

"Boss, Qin Gongzi said that he solved the first problem. ”

"It's not so easy, these questions are all difficult, you still really believe the words of that Qin Niangzi. Zu Shengcai said lightly, his brows furrowed slightly, and he stood up and walked to the place surrounded by everyone.

"Let me see the answer. Zu Shengcai shouted, some people even got out of the way, Zu Shengcai walked to the table and just swept three breaths of his eyes on the Qin Dynasty paper, and then his body trembled, as many people guessed, these questions, Tianyu Gate does have some answers, even if there are no answers, there are some ideas.

"Okay, good!" Zu Riheng suddenly shouted, "Young Master Qin, this question is well solved, yes, I think this is the answer." ”

Qin Chao smiled slightly, this problem Qin Dynasty naturally did not use normal methods to solve this problem, but used the 'differential triangle' method of later generations of Barrow. Barrow was the first 'Lucas Professor of Mathematics' at Cambridge University, who taught courses in elementary mathematics, geometry and optics, and was later named one of the best deans of Trinity College during the Restoration, but he is most famous for being Newton's teacher and the one who discovered Newton's genius.

Barrow's method of calculating the tangent of a curve is also one of his outstanding achievements, which is of great significance for the birth of calculus.

Now that Jing Shuo agrees with this answer, let's move on to the second question. The Qin Dynasty brush licked the ink slightly, and then put the pen on the paper. "This method is a virtual equation method, which divides the line segment b into two segments x and b-x......" This problem was still not written in the formal way of later generations, but used the famous solution of the great mathematician Fermat in the 17th century.

Soon Qin Chao stopped writing and glanced at Zu Riheng and Zu Shengcai.

"Wonderful, wonderful!" Zu Riheng's eyes flashed, and he muttered to himself excitedly, Zu Shengcai contemplated with his eyebrows, and after a while, his body trembled, and his face was a little ugly.

"This third question is indeed a bit difficult. Qin Chao licked the ink with a smile on the tip of his pen, and wrote quickly on the paper again, and Qin Chao put away his pen in an instant, "This is the answer to the third question." After finishing speaking, he dipped the ink again, and after a while, "This is how the fourth question is solved, but the fifth question is not difficult!" Qin Chao said that the difficulty was not small, but the pen moved like the wind, and the pen stopped in an instant.

"Okay, that's the answer to question 5!

But who can advise at this time, the first question that the Qin Dynasty solved, one by one, is still thinking about why and whether there are mistakes.

Of course, Qin Chao knew this, and he licked the brush slightly: "This sixth question is a good question, very representative, and the most difficult, I'll try!" put down the pen again, and it was also a moment, "I'm sorry, it seems that I have solved it too." Qin Chao smiled and put the pen on the pen rest, and then stood up directly and walked to the previous banquet, and drank slowly. (To be continued.) )
