The Favorite Demon Empress: Husband, come give birth to a baby

Chapter 101 Solving His Problem
After eating, Cang Yan thought hard, and didn't make things difficult for her anymore, and didn't know what he was thinking hard about.Unable to hold back her drowsiness, she leaned on the bench and fell asleep.

His eyes suddenly fell on her, and seeing her crooked sleeping posture, his impetuousness became less, and a happy mood emerged spontaneously.He walked over and straightened her neck so that she was leaning on the chair

Today, the envoy of Fanli brought the order of King Fanli, once Cang Yan could not solve their problems, he would stop paying tribute to Cang Yan from then on.They were well prepared this time, and even Cang Yan's group of think tanks couldn't solve it.

Although he was a little sarcastic, it was not easy to explode in front of envoys from other countries.What kind of think tank is it? It's just a bunch of wine bags and rice bags. Fan Li Guo wants to say that there is no one in Cangyan Kingdom in front of everyone, so there is nothing to worry about.

Leaning on the chair for a long time, her neck was a little sore, Jiang Taoyao woke up and thumped the back of her neck, noticing the paper in Cang Yan's hand.This is not the point, the point is that there is a striking formula written on the piece of paper in his hand, which frightened her so much that she couldn't stand up.

"Let's go! Pythagorean theorem? No dizziness?"

He suddenly raised his head, his eyes sparkling, "You know?" With anticipation, surprise, and uncertainty.

"Of course I know!" She took the paper to observe, and there was a question on it that proved the formula of the Pythagorean theorem.She picked up the writing brush on the table, and she became weak after writing the first character, and stopped there and couldn't write.

"I know you can't be trusted."

Cang Yan was about to snatch the paper, but she withdrew her hand and curled her lips in embarrassment: "I just want to say that my handwriting may be ugly."

He chuckled: "I've learned it." The note she left him last time, those crooked words, were much inferior to her literary talent, maybe they weren't called words at all.

Only after Jiang Taoyao’s questioning did she realize that this was a question brought by the envoy Fan Li. Without saying a word, she picked up the pen and worked hard on the paper. She frowned every time she wrote, blaming her for not practicing the brush well. Character.

She makes 8 congruent right-angled triangles on the paper, assuming that the lengths of their two right-angled sides are respectively a and b, and the length of the hypotenuse is c, and then make three squares whose sides are respectively a, b and c. They are assembled into two squares as shown in the figure above. As can be seen from the figure, the side lengths of these two squares are a+b, so the areas are equal. That is, a+b+4x1/2ab=c+4x1/2ab, so a+b=c.

Although the movements were not smooth and flowing, the moment the pen was written, Cang Yan was indeed startled.He picked up the paper, apparently unable to understand it, "Is it alright?"

"Take it, and keep them obedient. In addition, I can also use it practically to calculate the actual distance from this corner to that corner." Jiang Taoyao used this formula, and Cang Yan had to obey.

Going happy with the paper in his hand, he asked her what she wanted.Jiang Taoyao thought about it, and asked him to ask how the other party knew this formula when he came back.

Cang Yan successfully solved the problem of turning Li envoy, the other party was shocked but convinced.Pay tribute and taxes honestly and lawfully.To her disappointment, Mr. Fan Li accidentally saw this formula in a cave, which also recorded its proof method and usage.

Everyone retreated, and Cang Yan was lying on the couch, his movements were windy and flowing, and his posture was enchanting. He pushed the cup to ponder, the corners of his lips slightly tilted, "It seems that in the legendary battle that God blessed, she was indeed the planner, no wonder Gong Han Feng is so fond of her. Apart from her status, she also has wisdom that others don't have, she is a talent."
