From Chasing His Wife To the Top

  Chapter 15 How do you know everything? (Please ask for votes~)

  Li Hao did not expect someone to ask questions so soon.

  Wu Lin couldn’t help shook his head after hearing the general’s question of drinking horses: “This question is actually very simple, but it’s hard to understand.”

  "Why do you say that?" Du Tao didn't quite understand. As a Chinese teacher, he only knew a little about these mathematical terms.

   "There are too many typical models for the general drinking horse problem, and there are 16 common ones. If someone deliberately asks Li Hao, maybe let him analyze these dozen models." Wu Lin expressed his concern.

Unexpectedly, Li Hao just smiled, and then said: "In fact, the problem of generals drinking horses is the shortest path problem. The problem is mainly based on'between two points, the shortest line segment' and'all points on a straight line. Among the line segments, the vertical line segment is the shortest, and it can be solved by using knowledge such as the nature of axisymmetric and the flat expansion diagram."

  "In particular, it is necessary to use axisymmetric conversion and transform space problems into plane problems to solve the shortest path problem in junior high school mathematics."

   "Then I will draw some common models for everyone here. These topics are all trapped. Students, would you like to take notes?"

  While Li Hao picked up the chalk, he also looked at the male classmate who just asked the question.

  The boy was stunned, then opened the notebook on the table, ready to take notes.

Li Hao drew a simple model on the blackboard behind him, and then turned around and said: "Let me tell you. First, there are two situations in two points and one line. The first is that the two points are on opposite sides of a straight line. Point A, B is on both sides of the straight line n. Find a point P on n so that PA+PB is the smallest."

   "You have done this type of question many times, based on the shortest line segment between two points, so which model is our more difficult? That is the shortest path problem in the three-dimensional graphics expansion diagram."

  "Let’s draw a cylinder first, where ABCD is an axial section of it, AB=8/π, BC=3, and if an ant wants to crawl from point A to point C, how long is the nearest distance?"

  As soon as this question came out, the students off the field immediately started the discussion.

  Because in the cognition of junior high school students, generals drinking horses are generally flat dotted lines, and three-dimensional graphics are rarely involved, and they are still cylindrical.

  Long Jiayang saw that no one seemed to be able to tell the answer, so he immediately asked Ji Mingcheng in front of him: "Mingcheng, can you figure it out?"

   "It doesn't feel difficult, but I just can't turn my mind for a while." Ji Mingcheng frowned and drew on the paper.

  Long Jiayang heard that even the Xueba in the class was so difficult to do this problem, and he immediately became happy: "Hey, even the Xueba can't do it. It seems that there are few that can do it here."

  He even craned his neck and looked at Liu Xiuyuan on the front left, and found that her draft paper did not write a complete answer, so he was even more convinced that this was a problem.

  But only Teacher Wu Lin laughed.

   "What's wrong? It's difficult?" Du Tao asked anxiously.

  Wu Lin shook his head: "This kid thief, in fact, this question is not difficult. It just converts the plane into a solid cylinder, which makes it impossible for many students to start."

  Li Hao saw no answer from the classmates in the audience, and said, “In fact, we ask for the shortest distance that the ants can crawl. We only need to unfold the side of the cylinder and ‘shortest the line between two points’ to get the result.”

  "Expand the cylinder, connect A and C, AB=12·π·8/π=4, BC is equal to 3, AC is equal to the square of 4 under the root sign plus the square of 3, and the final result is equal to 5."

  After Li Hao finally wrote the answer on the blackboard, he looked back at the boy: "This variant question, do you understand it?"

  The boy seemed to blush, he finally nodded and sat down.

  In this way, in the next half an hour, the students in the audience asked Li Hao five or six questions one after another, and he was able to answer them likewise, and even set aside some time for them to explain the extension questions.

   His performance completely conquered the students below.

  At this age of junior high, as long as you have the level and talent, you will be admired and respected by many people.

   "Papa Papa!"

  The students even applauded Li Hao spontaneously.

  In fact, not only the students, but even the teachers standing at the back were surprised.

  Li Hao's condition and typhoon today are like a teacher who has been in education for many years, and even more experienced than some teachers who have just come to the school.

  The most important thing is that the rhythm of his lectures is just right, so that Du Tao couldn't help but sigh: "This kid, he will be a teacher when he comes out of school."

  "It is estimated that his ambition is not to be a teacher." Teacher Wu Lin narrowed his eyes and thought.

  But at this moment, a girl stood up, and Li Hao looked over and found that it was another student in Class 8.

  She bluntly said: "They were all asking questions about mathematics, physics and chemistry just now. Can I ask you questions about liberal arts?"

  Li Hao smiled bitterly in his heart: The head teacher of this class 8 is really unwilling to give up, and the ghost is still there.

   So he said: "Well, this"

   "Actually, I'm just a 46 student in grade, not every subject is strong, otherwise, I can get the first grade, right?"

  As soon as this sentence came out, everyone agreed. After all, boys' liberal arts are generally weak, which is also a tacit fact.

   "But well, I can do my best, you can ask."

  Li Hao turned the front of the conversation and faced him directly!

  The girl seemed to be prepared. She picked up the notebook and read: "Who is the emperor with the fewest concubines in the unified dynasty?"

   "Wow~~"

  Many classmates got booed when they heard this question.

  Because they all know that the emperor’s harem has three thousand beauties.

  If you ask the emperor with the least concubines, they really don’t know.

  Ke Class 16 students gradually realized something was wrong.

   "Hey, you said, why do students in Class 8 always ask these weird questions?"

   "Yes, even the emperor with the fewest concubines is asking questions like this. How could Brother Hao know!"

   "That's right, we don't test these in the book!"

   "Damn, beat them up later."

  Xu Zijun is very angry. In fact, as early as when the third student in Class 8 asked, he noticed something was wrong.

  Isn't this showing that you are bullying your brother?

  Long Jiayang was also angry and said, "Brother Jun, you will teach the two men later, and I will do the female one."

   After hearing this, Xu Zijun turned to look at Long Jiayang.

  Long Jiayang immediately changed his words: "I mean, I took the girl in our class to ask the girl for an explanation, to ask for an explanation."

  Li Hao was happy when he heard this question, and then said: "In fact, the answer to this question also appeared in the history books."

"Oh no?"

"real or fake?"

   "It's bragging."

  Li Hao immediately wrote the three words Zhu Youyun on the blackboard: "Ming Xiaozong Zhu Youyun!"

"He is the only monogamous emperor in history. He has only one queen, no concubines and beautiful women; Ming Xiaozong and Queen Zhang get along every day and night, like ordinary people; and he is also a good emperor, diligent Political affairs, attach importance to the judiciary, open a wide range of words, and work hard to reverse the corruption of the government!"

  As soon as this passage came out, everyone was confused.

  They thought, why did Li Hao even know how many wives the emperor had? !
