The imperial eunuch and the imperial edict came to the prince consort to ask questions.
The Prince Consort's abilities are truly incredible.
Qin Wenyao looked at it, his face full of joy and pride.
No matter how strong Qin Yu's ability is, he is still his son.
The man looked at Qin Yu, his eyes full of respect, and he bowed respectfully again, "Wu Youcai, who holds the humble position of Imperial Academy Supervisor, has met the Prince Consort."
In the past two days, Wu Youcai did nothing in the Imperial College except studying simple numbers and line charts.
For arithmetic calculations and research, the role of simple numbers and line charts is really huge.
Especially simple numbers can make calculations easier and more convenient.
Wu Youcai was originally a calculation fanatic.
Qin Yu completely conquered him with just these two things.
Qin Yu nodded and said thoughtfully: "Well, if you have any questions, just ask them directly."
Wu Youcai was just about to speak.
Emperor Wei walked in from outside the house.
Liu Shangwen and Wu Youcai hurriedly bowed and said: "I have met Your Majesty in this humble position."
Emperor Wei was stunned for a moment, then nodded, "What? You also came to the Ministry of Revenue to help?"
Liu Shangwen hurriedly said: "Back to Your Majesty, Wu Jiaoling has a few arithmetic questions that he would like to ask the Prince Consort for advice."
Hear this.
Emperor Wei was startled and couldn't help but look at Qin Yu, "My son-in-law is really promising. He even came to you to ask questions about the imperial edict?"
He knew that Qin Yu had something in arithmetic, but he didn't expect that he was so capable.
Emperor Wei stood aside and had no intention of leaving.
Wu Youcai was a little nervous and didn't speak.
Qin Yu looked at Emperor Wei and said thoughtfully: "Your Majesty, why don't you just do whatever you need to do?"
Liu Shangwen: "..."
Wu Youcai: "..."
In the Wei Dynasty, Qin Yu was probably the first person in the world who dared to openly attack the Emperor of Wei.
Emperor Wei waved his hand, "You should be busy with your business. I will just take a look and won't disturb you. In fact, I am also very interested in arithmetic."
Qin Yu: "..."
He finally understood why Xiao Nan's computing power was so strong.
It seems that Xiao Nan still inherited something from Emperor Wei.
Qin Yu nodded, then looked at Wu Youcai and asked: "Wu Jiaoling, if you have any questions, just ask."
Wu Youcai hurriedly said: "Prince-in-law, I have been studying arithmetic in my humble position for so many years. I have been studying the same thing for many years, but I still have no clue. I don't know if my prince-in-law can find a solution."
Qin Yu said lightly: "But it doesn't matter."
Emperor Wei stood aside and listened with curiosity.
Wu Youcai said: "I wonder if Prince Consort has a way to calculate the height of a mountain? For so many years, Beizhi has been working on the calculation of mountain heights, but there is still no progress. However, Beizhi believes that this is not an unachievable problem.
, I believe that everything can be calculated and the result can be obtained."
Hear this.
Liu Shangwen was stunned.
Emperor Wei felt shocked.
Calculate the height of a mountain?
Can the height of a mountain be calculated?
Unless it is a cliff, it is probably impossible to even measure it.
They think this is simply an impossible problem.
at the same time.
Qin Wenyao and Xiao Nan also came over.
They also wanted to hear what questions they wanted to ask him about according to the imperial edict.
When I learned that I needed to calculate the height of a mountain.
Xiao Nan, Qin Wenyao and Shen Binglan also felt that it was impossible.
Since ancient times, no one has been able to calculate the height of a mountain.
And there is simply no way to start with this.
Everyone thought it was impossible.
Wu Youcai looked at Qin Yu expectantly, feeling that Qin Yu must have a solution.
Qin Yu listened with a calm expression on his face, "Isn't it just about calculating the height of the mountain? It's not very difficult."
The words fell into place.
Emperor Wei looked shocked!
Xiao Nan looked shocked!
Qin Wenyao was even more shocked and couldn't open his mouth from ear to ear!
You can calculate the height of the mountain, and it's not difficult.
this......
What kind of tiger and wolf words is this!?
Wu Youcai had a look of excitement on his face. He knew that calculating the height of the mountain was achievable and Qin Yu must have the ability.
"Prince-in-law, how do you calculate it?"
Wu Youcai looked at Qin Yu with excitement.
Qin Yu said lightly: "Use shadow."
shadow!?
The faces of Xiao Nan, Wei Huang, and Qin Wenyao were full of shock.
Wu Youcai became even more excited and excited.
"Hahaha......"
Wu Youcai laughed excitedly, "Shadow! It's really a shadow! I knew it must be a shadow!!!"
Although Wu Youcai correctly guessed it was a shadow, he didn't know how to calculate it.
But this alone was enough to make him excited.
Emperor Wei and others were full of confusion.
They really didn't understand how Qin Yu could measure the height of the mountain through its shadow.
this......
This is simply appalling.
Emperor Wei looked at Qin Yu and raised his eyebrows, "Son-in-law, you...can you really measure the height of the mountain with your shadow?"
Qin Yu nodded, "Of course you can, it's not that difficult in the first place."
As he said that, he looked around, and then looked at the pagoda built in the palace, "Why don't we use the shadow of that pagoda to calculate it."
Wu Youcai looked in the direction of Qin Yu's finger, and then said: "Okay, just listen to the prince-in-law."
Afterwards, Qin Yu and Wu Youcai went straight to the pagoda.
Wei Huang, Xiao Nan and Qin Wenyao didn't hesitate and followed directly.
They also want to witness a miracle.
Qin Wenyao just walked to the gate, then came back and looked at the officials in the hall, "You guys check it carefully, I'll be back as soon as I can."
As soon as he finished speaking, Qin Wenyao hurriedly caught up, fearing that he would be left behind.
Not long after.
Everyone came to the pagoda.
At this time, everyone's eyes fell on Qin Yu. They wanted to see what kind of method Qin Yu could use to calculate the height of the pagoda using shadows.
Qin Yu looked around, then took a bamboo pole not far away and inserted it into the ground.
Afterwards, Qin Yu used a ruler to measure the height of the bamboo pole and the length of the bamboo pole's shadow.
At this time, the height of the bamboo pole is four feet, and the length of the shadow of the bamboo pole is six feet.
Everyone looked at Qin Yu's operation with confusion.
But at this time, Wu Youcai was already excited and trembling, because he had guessed Qin Yu's method.
This method is not that, but...but no one has thought of it since ancient times!
He truly deserves to be called the Prince Consort.
Immediately afterwards.
Qin Yu also measured the length of the pagoda's shadow to be forty-eight feet.
Then he wrote the vertical form.
4/6=?/48.
4*8/6*8=?/48,?=32.
Then Qin Yu looked at Emperor Wei and asked, "Your Majesty, is the pagoda 32 feet high?"
Emperor Wei's eyes widened, he nodded involuntarily, and exclaimed: "That's right! It is indeed three feet and two feet, thirty-two feet high!"
