Yue Pingting's body was trembling.
His voice was also trembling, and he could not even speak clearly.
"Mom, you, you, you said…"
"I mean, your Aunt Zhou said that you were very serious in your studies with Xu Heng this morning. Are you planning to slack off?"
Yue Pingting was dumbfounded. No, Mom, what do you mean? Mom…I…You…"
"What are you waiting for? Go! Seriously, he only thought of slacking off every day! Go find Xu Heng!"
Yue Pingting was kicked out of the house.
He watched Yue Pingting walk over.
Her mother smiled and sent a message to Zhou Xiu'e."I went! I'm going!"
Zhou Xiu'e said," Yes! Yes!"
To be honest, Yue Pingting's mother liked Xu Heng very much!
In the past, Xu Heng's grades were not good, but he was very sensible and obedient, so he was doted on.
Now that her results were at the top, she liked it even more!
More importantly, the two families were very close to each other.
No one wanted their daughter to marry far away!
Therefore, she was 120% satisfied with Xu Heng!
Xu Heng and Yue Pingting were a couple, so she naturally wouldn't say anything. The only problem was that they weren't very old.
But these two parents were very open-minded.
17 years old!
Who hadn't done it when they were young?
Therefore, they didn't mind. The only thing they cared about was not to cause an accident so early.
But Yue Pingting didn't know.
She was back.
With a bitter face.
" What's wrong?" Xu Heng asked.
Yue Pingting said," My parents are a little too much. Sob, sob, sob. I wanted to sleep for a while, but they didn't let me sleep. They rushed me here to learn from you."”
Xu Heng said," Damn, it's not a big deal. Go to my room and sleep."”
Yue Pingting shrunk her neck." I don't want to. I'm not going. I'll go next door."”
Xu Heng said," My mom cleaned up the room next door. There's no sleeping mat or anything else. There's nothing but a plank bed. Are you going?"”
"I…"
Xu Heng said," Don't worry."
"Then call me in an hour."
"Alright!"
Yue Pingting went there right under Zhou Xiu'e's nose.
Yue Pingting went to Xu Heng's room for lunch, and Zhou Xiu'e went to the study.
"Brat, you only know how to play games! Rest for a while! Give the computer a break! Go for lunch break!"
"Get lost!"
Zhou Xiu'e chased him away!
He didn't want Xu Heng to stay any longer.
Xu Heng: "???"
"Mom, what are you doing? Why are you so surprised today?"
Xu Heng went to the living room and laid down on the sofa.
"Get up, I'm going to clean up!"
Xu Heng: "???"
"Go back to your room!"
Xu Heng finally understood that this was the reason for their relationship!
"You guys still said that you wouldn't let me do anything. Now, you actually want me to go?”
Zhou Xiu'e rolled her eyes." Stop talking nonsense! Hurry up! Hurry up and go!"
Women understood women the most.
"Do well!"
Xu Heng was pushed in.
Yue Pingting blinked her big eyes, her face full of doubt.
Zhou Xiu'e slipped away." I'm sorry, Little Yuezi. You can sleep on your own. You guys can sleep on your own…"
What did he say!
You guys?
Xu Heng was speechless.
"You saw it too. My mom is crazy. Sigh…"
Yue Pingting pouted.
She shifted her seat to make room for Xu Heng.
"Here you go."
Xu Heng lay down, and Yue Pingting put his hand under her neck.
"Xu Heng, can I ask you a question?”
Xu Heng turned around." Wait a minute."
Yue Pingting was speechless.
Wait a minute?
Wait for what?
"Woo…"
There was no need to think, she already knew.
This sudden kiss.
After that.
Xu Heng smiled evilly." Ask away!"
Yue Pingting punched Xu Heng's chest." I'm serious. I'm asking you a math question!"”
Xu Heng replied," Yes."
"The inner angle of the triangle ABC is sinA square root 2sinB=2sinC, then what is the minimum cosC?”
Xu Heng's first reaction was," Is it very difficult?”
Yue Pingting said," This was the last question of the college entrance examination!”
"Phew…"
"Now that I have you, I'm so arrogant that I'm going to look for college entrance examination questions to study!”
Xu Heng was speechless.
"So, how do we solve this question?"
Xu Heng said bluntly," What I'm investigating is the combination of trigonometric-functions and basic inequations. According to the theorem of sines, we can get A square root 2B 2C!”
"Adding the law of cosines, cosC=(A squared B-C squared)/2AB…"
"Combining the two, using the basic inequation and calculating, it will do.”
"So the answer is (Square Root 6-Square Root 2)/4.”
"There are similar questions for this question.”
"If sinA=2sinBsinC, then what is the minimum value of tanAtanBtanC?”
"You can do this after you wake up.”
Yue Pingting replied," Alright…"
Her long eyelashes were already overwhelmed.
She was too sleepy.
She didn't sleep well last night and woke up so early in the morning." I'm so sleepy…ha…"
Yawning, she curled up in Xu Heng's arms like a cat.
She was asleep.
Very obedient.
Xu Heng took a deep breath and fell asleep.
When he woke up, Yue Pingting was already doing some calculations on the bed.
"See if it's like this! Did I do the right thing?"
Xu Heng took a look and gave him a thumbs up." Not bad! Awesome!"
Yue Pingting smiled and took a bite of Xu Heng." You're the best! You taught me!"
"But don't be happy too early. I still have a college entrance examination question to ask you.”
"Stop!" You're only in your second year of high school. Can you stop looking at the college entrance examination questions and take it step by step!”
Yue Pingting said," I'm not stupid. I won't do questions that I haven't learned before! What I did was what I learned."
Xu Heng rolled his eyes." Then you still don't know how to?”
Yue Pingting was speechless." I, I…I…"
Xu Heng scratched her nose." Let me see the questions."”
The question entered his eyes.
Whoosh!
So many words.
Our country has a long history of stone and stone culture. The seal is one of the representatives of the stone and stone culture. The seal is mostly in the shape of a cuboid, cube, or cylinder. However, the seal of Guanyun Duguxin in the long period of the north and south is in the shape of a semi-regular polyhedron (Figure 1).
A semiregular polyhedron was a polyhedron that was surrounded by two or more regular hexagons.
The semiregular polyhedron embodied the beauty of mathematics.
Figure 2 is a semiregular polyhedron with 48 edges. All its vertexes are on the surface of the same cube, and the length of the cube is 1.
How many faces does the semiregular polyhedron have and how long are its edges?
Xu Heng looked at the map.
Yue Pingting was standing at the side, blinking her big eyes.
"So many words! There's even such a diagram. What Dugu Xin? In order to test us in the college entrance examination, he even brought out history.”
"Looking at this picture, it should be a cultural relic, right?”
Xu Heng rolled his eyes at Yue Pingting.”
Yue Pingting shook her head.
Xu Heng said," He's an incredible figure in history, and he's also the most awesome father-in-law in history!”
Yue Pingting: " How awesome can it be?"
Xu Heng said," His four daughters are all empresses. He was an important general in the Northern Zhou Dynasty. It was said that his seal was found by a student on his way home from school. At first, he thought it was a strange stone, but he never expected it to be a priceless treasure.”
"It's still on display in the museum.”
Yue Pingting's eyes lit up and she began to be interested.
" Knowledge points increased again!"
"Speaking of which, Xu Heng, do you always let your imagination run wild when you do the questions?”
Xu Heng rolled his eyes." Am I imagining things? I'm doing this for you! To give you some general knowledge."
Yue Pingting was speechless.
Xu Heng said," Alright, let's not be long-winded. Let's look at the question. The first part is all nonsense. The part at the back is the main topic. It's related to mathematics. It's about how a three-dimensional object understands a polyhedron.”
"If you know about the Eulerian formula, this question will be very simple!”
Yue Pingting lay beside Xu Heng and listened carefully.
Xu Heng was lying down." According to the Eulerian formula, v f-e=2!”
Yue Pingting said," Wait, what?”
Xu Heng said," V represents the apex, f represents its face, and e represents the number of edges.”
"Let me ask you, the number of edges is 48, so what is the top?”
"Ah?" How much? Let me see…let me see…1, 2, 3, 4…"
Xu Heng asked," What are you doing?"
Yue Pingting pouted." Let me count!”
Xu Heng said," Stop counting. It's 24. Since you already know the number of edges, this noodle should be out, right? There were a total of 26 sides.”
"Do you understand?"
Yue Pingting was dumbfounded." You tell me your story first. I'll digest it later. What's next?"”
Xu Heng said," This question is about the length of the ridge. We have to look at Figure 2 and do a main view of it.”
Xu Heng began to draw.
Yue Pingting could barely keep up.
"Yes, yes! Continue."
Xu Heng said," It's a simple calculation, so the final answer is the square root 2-1! You digest it first, ha…I'll go back to sleep.”
Yue Pingting looked at the question and blinked her big eyes.
She looked at the question and then at Xu Heng.
"Pow ~~~!"
She couldn't help but give him a bite.
"You're awesome!"
Xu Heng smiled without opening his eyes.
Yue Pingting continued to look at the questions, and she stayed by Xu Heng's side.
He looked like a cat.
When Xu Heng opened his eyes again, Yue Pingting looked at him in a daze.
"Don't say it. Take a closer look. You're quite handsome!”
Wasn't this nonsense!
"But I've never seen it up close! The more I look at him, the more handsome he becomes."
Alright then!
Xu Heng smiled. Please continue with your bullsh * t.
When they woke up, it was almost four in the afternoon.
He Junfei came knocking.
"Xu Heng…"
He was holding a test paper in his hand.
A college entrance examination paper.
Ever since he found out about Xu Heng's results, He Junfei became anxious.
He desperately wanted to improve.
At the same time, he also wanted to test Xu Heng's true strength.
All this while, he hadn't really probed Xu Heng's strength.
He knew that Xu Heng was definitely stronger than him!
However, no one knew how powerful he was.
"Xu Heng! Are you free? I want to ask you a few questions."
"College entrance exam questions, okay?"
Yue Pingting was surprised." You've been doing college entrance exam questions recently?”
Have you been doing it recently?
Also?
He Junfei said," Uh…You mean Xu Heng is the same?”
Yue Pingting smiled and quickly waved her hand." No, no, no, Xu Heng wouldn't do it. If it were me, I would look at the college entrance examination questions that I have learned so far and find some that I don't know. Let Xu Heng explain it to me."”
He Junfei's heart skipped a beat.
What happened to the students of Yunshan High School?
Yue Pingting, you're only in your second year of high school, and you're already reading the math questions for the college entrance exam?!
Am I falling behind again?
？？？
"Even the ordinary second-year students in your school are starting to solve the college entrance examination questions?”
He Junfei was dumbfounded.
He still thought that he was very outstanding!
However, he never expected that even the ordinary students would start.
He felt that he had suffered a great humiliation.
For a moment, He Junfei stared at Xu Heng and felt that the gap between them was even greater!
It was no longer something that could be measured by a college entrance examination paper!
" You have a question for me?" Xu Heng asked. Come on, hurry up and ask. Let's go. We're still waiting for dinner.”
One of He Junfei's motives for asking the questions was finally dispelled.
But his other goal was to know the answer!
He handed the test paper to Xu Heng." This question.”
Xu Heng glanced around.
Title:
In ancient China, the Book of Changes used hexagrams to describe the changes of all things.
Each " double hexagram " was composed of six lines arranged from bottom to top. The lines were divided into the Yang line "--" and the Yin line " one by one ". As shown in the picture, it was a double hexagram. If one was chosen from all the double hexagrams, then what was the probability of the double hexagram having three Yang lines?
He Junfei said," I don't know much about the Book of Changes…"
Yue Pingting covered her mouth and laughed.
Xu Heng raised his eyebrows." This is a math question, not the Book of Changes."”
"Um…"
He Junfei sweated.
Xu Heng said," This question has nothing to do with the Book of Changes. You just need to convert the text into mathematical language.”
"Six items, divided into two groups, so let's first calculate how many there are.”
"How much is it?"
He Junfei knew how to do this." One is two types. If there are six, it's two to the power of six, which is the total number.”
"I understand…I understand!"
He Junfei suddenly understood the question.
He smiled at Xu Heng.
However, Xu Heng said," You're only in your second year of high school. This paper isn't very suitable for you.”
He Junfei asked," Why do you say that?”
"I think it's because I haven't been exposed to the college entrance examination questions that I'm stumped by the surface words on this question.”
"Besides, I know everything my teacher taught me. Besides, I've already learned the goose beyond the outline, so isn't it good to put some effort into these questions?”
"Even Yue Pingting said it, aren't you the same?”
Xu Heng said," But Yue Pingting knows her place. The questions she does are all what we have learned before or are learning now, but you are different!”
He Junfei pursed his lips and awkwardly adjusted his glasses." So…?"”
Xu Heng said," Look at the fill-in-the-blank questions in front of you. There are mistakes and also multiple choice questions.”
"Stop pretending to be fat!”
He Junfei's scalp went numb." You, how do you know that I did something wrong? You just took the test paper. Have you done this test paper before?”
Xu Heng shook his head." When I was looking at your question just now, I noticed it after a few glances.”
F * ck!
I beg for all support! Kneel and thank him!
