After being teased by the girl, Han Du's face turned red even with his mentality. After chatting for a few words, Han Du said goodbye and left, not forgetting to bring the girl's answers with him.
As soon as he returned home, Han Du immediately ordered his maid to find Yu Qian.
Han Du hadn't finished his cup of tea when Yu Qian came.
"Teacher, are you looking for me?"
Han Du nodded and motioned for Yu Qian to sit down. After Yu Qian sat down, he put down the tea cup and held his hands in front of his stomach. He asked in a calm tone, "I asked you to announce the topic at the beginning, but I seem to remember not asking you to say that as long as someone can
Once you figure it out, you can just give the reward to the other party, right?"
Yu Qian thought that the teacher was blaming him, so he quickly explained with a smile, "The disciple did make a spur-of-the-moment decision without consulting the teacher in advance. It's my fault."
Han Du looked at him and sighed deeply, "If I just want you to admit your mistake, then why should I call you here?"
Yu Qian was stunned for a moment and quickly explained, "This disciple is indeed a little impulsive, but it shouldn't be a big problem, right?"
"Oh? Why do you think it's not a big problem?" Han Du asked with a faint smile.
Seeing this, Yu Qian thought that the teacher just scolded him casually, and said with a smile, "This question is very difficult, and it took the disciple a long time to solve it. It is impossible to solve it in just a few days."
things."
Han Du glanced at him and chuckled, "Do you really think no one can solve it? Then look at what this is."
After finishing speaking, Han Du took out Han Jingyun's answer and handed it to him.
Could anyone really solve it in such a short time? Yu Qian was a little confused and a little unconvinced.
I took the paper handed by the teacher and opened it. A look of confusion suddenly appeared on my face. There was no picture at all on it, let alone a regular heptagon. What did the teacher mean?
Seeing Yu Qian's confused eyes, Han Du pointed at the answer in his hand and said, "Look carefully."
Yu Qian lowered his head to look carefully again, and soon he found clues, and his face couldn't help but show a slightly surprised look. As he continued to look, the look on his face became more and more serious, until he finally let out a long sigh.
I admire you, I really admire you! Using algebraic methods to solve geometry problems is simply unheard of, unheard of!"
Before Han Du could speak, Yu Qian lowered his head again and read the solution to the problem from beginning to end. He felt a sense of relief all over his body and started to tremble with excitement.
"Awesome, really amazing." Yu Qian was shocked and shook his head repeatedly. "Algebra and geometry are two completely unrelated fields. How can they be connected? Doesn't that mean that algebra and geometry are also connected?
, but we didn’t know it before?”
"Now that we know that there are people outside the world, do you still dare to speak out?" Han Du decided to give Yu Qian a warning, hoping that he would think twice before doing anything in the future to avoid unnecessary trouble in the future.
Yu Qian had no intention of listening to Han Du's teachings. He suddenly raised his head and looked at the teacher and said, "Didn't the teacher find out? This problem-solving method has completely created a new knowledge!!!"
"Ah?" Now it was Han Du's turn to be surprised.
He suddenly grabbed the paper in Tai Qian's hand, lowered his head and looked at it carefully.
Yu Qian said quickly at the side, "Teacher, if geometry problems can really be solved by algebra, then the knowledge involved will be
too big"
Han Du looked at it again and raised his head after a while. He had to admit that Yu Qian's thinking was sharp. Although he had also seen the problem-solving process, he did not think about the connection between algebra and geometry at all.
Seeing that the teacher didn't speak, Yu Qian continued, "Teacher, the person who solved this problem should be the Queen Mother, right?"
Han Du did not hesitate and nodded directly, "Not bad."
Yu Qian sighed with admiration, "I was indeed rash and forgot about the Queen Mother."
How could Han Du bother to teach Yu Qian a lesson now? He was pacing back and forth anxiously, and suddenly stopped in front of Yu Qian, saying, "Now is not the time to talk about this, your thoughts are more important. Come, follow me into the palace to see the Queen Mother."
"
Yu Qian glanced at the teacher in surprise, but before he could react, he was forcibly grabbed by the arm and taken away.
In one day, he entered the palace twice in a row.
Even Han Jingyun was very surprised, "Brother, what's going on?"
Then he looked at Yu Qian and said with a smile, "Yu Qian, you are good at mathematics."
Being praised so much by the first person in mathematics, Yu Qian showed a look of shame on his face, and he quickly saluted and said, "The Empress Dowager is ridiculously complimenting me, and Yu Qian is too embarrassed to deserve it."
"You don't have to be self-effacing. Being able to solve the problem on your own is indeed very impressive." Han Jingyun said with a smile.
After hearing this, Yu Qian felt even more uncomfortable. He was able to draw a regular seventeen-sided polygon only by chance after more than a year of hard study.
In other words, Yu Qian's success comes with a little bit of luck.
But this problem fell into the hands of Han Jingyun, and she was able to solve it in just a few days. Moreover, she also used algebraic methods, which made Yu Qian feel like he was standing on a high mountain.
Han Du didn't have time to wait for the two of them to be humble to each other. He directly took out Han Jingyun's problem-solving method and asked, "Sister, how did you come up with the idea of using algebra to solve geometry problems?"
Han Jingyun looked at it and smiled and said, "Brother, you want to ask this? There is nothing to say. When I heard the title, I was just curious about whether I could solve this problem through calculation. I didn't expect that I tried it and it worked.
It really worked.”
Han Du's eyes widened in surprise and he looked at the girl up and down.
Being looked at so strangely by his eldest brother, Han Jingyun also became confused, "What's wrong?"
"Isn't the girl studying the connection between algebra and geometry?" Han Du asked.
"The connection between algebra and geometry." Han Jingyun frowned. The next moment he understood it instantly, his eyes lit up and he said with surprise, "Brother, what you mean is that there is some kind of connection between algebra and geometry? This is a new knowledge.
ah!"
"Brother is really amazing, he can even think of this."
Of course Han Jingyun knew that the eldest brother must have thought of this after seeing her solve the problem of drawing a regular heptagon with a ruler through algebra.
But even so, it is very powerful. At least, she, who uses this method, did not think of it.
"It's not me." Han Du shook his head with a smile, "If I could have thought of it, would I have waited until now? I would have thought of it the moment I saw your answer."
Of course Han Jingyun would not think that the eldest brother was being modest. In addition, the eldest brother was so eager to bring Yu Qian to see her. She immediately looked at Yu Qian and said, "Did you think of it?" The girl teased her, even if it was Han Du.
His face turned red because of his mentality. After chatting for a few words, Han Du said goodbye and left, not forgetting to bring the girl's answer with him.
