All-round mathematician

Chapter 157 The Explosion of Academic Olympiad Music

It was already 12:[-] noon when the first exam ended. The organizer had already prepared a buffet, the papers were collected, and the first day of the exam was over.

The eight people in Huaxia sat at a round table, and the food had already been placed in stainless steel trays.The two leading teachers were hesitant to speak several times, and the faces of the students were not good-looking.

Teacher Qian's heart sank. It took him three hours to solve the last question, and he finally solved it. The initial thinking was wrong, and he didn't expect it to be so complicated.

"This is analytic geometry. The simple application of algebraic geometry that students usually talk about can be done. If you are a freshman and sophomore, this question will not take an hour. If you use the knowledge points in high school, it is too difficult. "

Teacher Qian is not optimistic about the results of today's competition. The only thing he feels lucky is that students from other countries may not be able to do it, and everyone is still on the same starting line.

"Morale is low." Teacher Zhou also found out the problem. Since he didn't perform well on the first day, he had to be well prepared for the second day, otherwise the impact would be even greater.

He winked at Teacher Qian and asked the latter to say a few words of encouragement. Teacher Qian understood and coughed: "En..."

"Gu... Gu..." Yang Fan swallowed a few mouthfuls of soup, and cried out comfortably: "I'm thirsty."

For four hours without a drop of water, both physical and mental strength were competing.Yang Fan's appetite was greatly shaken by the good-tasting soup, and he began to gobble it up.

The sponsor was not short of funds, and the food in the buffet was quite rich. Yang Fan chose all the top-quality seafood and high-end meat.

Teacher Zhou frowned. What a weak student, don't you know that you can't eat?Everyone is worried about the grades, how can he eat it, and it is so greasy.

"But the mentality is really stable." Teacher Zhou was mixed.

Teacher Qian's eyes lit up, and he almost cried out with joy, how could he forget this one.After a few days of contact, it was Teacher Qian who really understood Yang Fan's background.

Not to mention artistic talent, mathematics seems to be one level higher than ordinary students, especially the conversion between music and mathematics requires quite profound mathematical knowledge.

Teacher Qian pretended to pick up a few shrimps from his own plate and put them in front of him, showing an amiable smile, and said, "Yang Fan, how are you doing with the three questions today?" After a pause, he pointed to the remaining students, Said, "Everyone also talk, talk while eating."

As soon as the words came out, the students opened up the chatter box and began to complain.

"The first two questions are okay, but the third question is not finished."

"Yes, the third question must have missed the condition or the question is wrong, no matter how it is calculated, it is wrong."

"There are several methods of calculation, and the answer is different every time. I am afraid that the American who made the question will lose face."

……

Several students said it was difficult, and they all said it was wrong. When Mr. Qian checked the calculation, he made all their mistakes. He knew in his heart that this time his luck was bad, and maybe only one of them had a chance.

Teacher Qian's eyes turned to the side, while Yang Fan ate with glib mouth, no intention of speaking at all.

Teacher Qian was full of black lines, and just as he was about to ask again, the sound of discussion from the US team separated by two tables came over.

"Shh." The index pointed to his lips to signal silence, and he quickly pricked up his ears to eavesdrop.

The Huaxia team members understood, bowed their heads and ate without making a sound.

"How are you guys doing?" said the voice of the American team leader Frederica, whom Mr. Qian had contacted many times.

"It's hard not to make it."

"I did it, but I always felt that the answer was wrong."

Teacher Qian and Teacher Zhou looked at each other, and they saw surprises in each other's eyes. Fortunately, everyone was similar.

"I asked the organizer just now. It seems that the order of the second day and the first day was wrong. The last question today is actually the most difficult one." Frederica said.

"Bah." Teacher Qian yelled, "Fucking Americans, they really don't know how to do things. There are mistakes like this."

I remember one time in the United States. Because the process was not rigorous, all the questions for two days were decentralized, and each did its own thing. In the end, it had to be invalidated and six questions were reissued. It was a waste of time for students and teachers.

At this point, Mr. Qian is concerned about whether the competition should continue, or whether to do it all over again.

"The three questions are the same in all countries today. We will continue tomorrow. Everyone is the same." Frederica said in a low mood, not in a good mood.

Not to mention China and the United States, looking around the cafeteria, it is filled with a dignified atmosphere. Teachers and students all eat with their heads down, and there are very few discussions. It is difficult for everyone.

"It's a bad start." Teacher Qian sighed.

"I'm full, the taste is so-so." Yang Fan picked up a toothpick to pick his teeth, the steak was a bit old, and there was too much seafood and garlic.All kinds of bad reviews.

The gauze on my hand was removed this morning to do the topic, and the wound is mostly healed.In the past few days, I have been inconvenient to eat, but today I finally made up for it in one step.

"Hey." With a full belch and the smell of garlic soaring to the sky, Teacher Qian who was next to Xundi really wanted to run away.

Teacher Qian suppressed the discomfort, and asked patiently: "They all said that the question was wrong, Yang Fan, how did you feel when you did it?"

"That question is very interesting. The question is correct, and I can do it." Yang Fan replied carelessly.

After the words fell, several pairs of eyes glared at him at the same time.Questioning, bragging, making trouble, all kinds of emotions.

Not to mention that the students didn't believe it, even Teacher Zhou didn't believe it, and said, "I thought about this question for a while and felt wrong and didn't continue. It took Teacher Qian... an hour to figure it out. Can you calculate it in time?"

Teacher Zhou still saves some face for his peers. If the teacher spends three hours, then the students may not be able to do it in the same amount of time. In addition to the previous two, if they have ideas, they may not have enough time.

"Teacher Zhou, don't give me credit, just say that I almost didn't make it. If you can think of the inspiration for that question, it won't take two hours. I'm afraid that the conditions for the question will be misleading."

Teacher Qian continued to explain, and said: "There are four angle conditions, and the figure is a triangle. After solving the geometry problem, I always thought that we need to add dotted lines, extended lines, draw circles, etc. That Yang Fan, tell me about your solution."

The trust in Teacher Qian's words can be seen by everyone sitting here, asking Yang Fan to give the answer without asking right or wrong, this is too exaggerated.

"It's not actually a geometry problem, it's an algebra problem." Yang Fan said.

"what?"

"impossible."

Seeing the disbelief of several students, Yang Fan continued to explain: "The geometric solution is wrong. No matter how many geometric solutions are used, the answers are not uniform every time. It can be seen from this that the person who made the question is quite knowledgeable."

"Use the angle reasonably, and then judge the proportion of the line according to the angle, so that the problem becomes algebra... I took 64 steps to solve it, and the answer is 35 degrees. Teacher, right?"

After listening to Teacher Qian, he really wanted to laugh up to the sky, and even Teacher Zhou was pleasantly surprised.

This topic, 800 of the world's top high school students here, at most three can solve it.And Huaxia has one person, and there is no better proof of Huaxia's mathematics excellence than this.

"Actually, 64 steps are really cumbersome. I have listened to analytic geometry for a while. If the Olympiad allows, the steps of this problem can be reduced to 19 steps. It is really a big difference. High school mathematics is really just elementary mathematics."

Of course, in order to be afraid of being picked on by others, going beyond the outline, etc., Yang Fan finally chose the way of high school.

The five students of the same generation were all dumbfounded, and they couldn't help thinking: what's so great, I can do it after learning analytic geometry in college.

"Well done, the sense of proportion is excellent."

Teacher Qian slapped the students on the shoulder fiercely to express his praise. He was a little unconvinced even for his classmates, let alone other countries.

"Ability beyond the syllabus is allowed in the Olympiad. But if you are the only one who solves this question with the syllabus, it is luck and luck, and it may not be convincing. Only by using high school methods can you prove that you are a strong high school student."

Discussion is discussion, the past cannot be changed, Teacher Qian said a few words of comfort, and prepared for the next day's competition.

On the second day, everything was normal. The Huaxia team was very strong. After calculation, it was very likely that one person would get a full score, two people would deduct more points, and the middle three would basically deduct less points for five questions.

The final result will have to wait for the awards on the third day.

In the Olympiad competition, the medals are divided into two pieces, individual and team.Personally, if you reach a certain score line, you can actually get a gold medal with a score of 30 or a full score of 42.

The total score of the group is used to compare the strength of the country.

Early in the morning of the third day, Teacher Qian and Teacher Zhou were very nervous. This year, they can no longer be compared to the Americans, otherwise it will be difficult to explain to the country.

The only consolation is that a student raised the total score by 6 points first. I heard that there may be two students who got the question right, and the other is a Russian-Indian.

Also today, at [-] o'clock local time in the United States, two world-renowned magazines are released globally.

A weekly magazine about the top people in the world.

A copy of the world's top mathematics - nature.
