" Ding, ding, ding…" A short bell rang. The exam was about to begin.
At 1.55, the invigilator began to read out the rules of the examination: "The rules are very simple. You have three hours to complete the test paper. You are not allowed to look around or go to the toilet during the test. You are allowed to hand in the test paper half an hour after the test.”
After the rules of the exam were read out, the papers were quickly distributed to everyone.
The paper introduction was divided into three questions.
The first question, let A and B be two points on the hyperbola x2-y2/2=z, point N (1,2) be the middle point of the line segment, and the vertical bisected line of the line segment meets the hyperbola at C and D.
Please confirm the value range of z.
"Damn, does it have to be so difficult?"
"Teacher, are you trying to play us to death?”
Coach, I don't know this question."
“……”
Just by looking at the first question, the entire auditorium was filled with wails.
This question seemed to be very short, but the knowledge used was unusually rich.
It covered almost all the knowledge points in high school.
Even though the people sitting there were all top students, they still scratched their heads when they got this question.
It was too difficult.
"Hey, who came up with this question?”
Zhou Luo saw through everything at a glance. Without much hesitation, he immediately raised his brush and started working!
Assuming that the equation for the equation of A and B was y=k (x-1) 2, and the hyperboloid equation was substituted…
…So the value range of z is (-1,0) U (0, infinity).
Zhou Luo quickly wrote down the process of solving the problem. Up until now, he had only spent three minutes.
"10 points." Zhou Luo heaved a long sigh of relief. He had burned many of his brain cells.
After checking that there were no mistakes, Zhou Luo raised his head and looked around.
On his left, a boy was trembling all over, and on his right, a girl was biting a pen and sweating profusely…Zhou Luo looked around, but there was no one who was writing.
…" Was it really that difficult? Zhou Luo didn't think so.
Suddenly, the corner of Zhou Luo's eyes narrowed. He saw Bai Chong sitting in the corner.
Unlike the others who were deep in thought, Bai Chong was writing furiously.
A black gel pen drew a beautiful arc in his hand. In the next moment, the answer was already on the paper.
En, to be able to become the top student of Chengyu Seventh High School, he really had some skills.
However, Zhou Luo did not mind. Bai Chong had some skills, but he had dozens of them.
What surprised Zhou Luo was that Lin Shanshan was also writing quickly.
Hmm, it seems like I do have the potential to be a teacher. In just a few days, I've turned a slacker into a top student.
Suddenly, Zhou Luo felt his vision darken. He looked up."F * ck, there's someone!"
He saw an invigilator wearing a Chinese tunic suit with a serious expression staring at him.
That burning gaze seemed to melt him in the next second.
"What are you looking at? Hurry up and do the questions." Feng Huadong said coldly.
Feng Huadong, the invigilator this time, was also the president of the Southwest Province Mathematics Association.
"…Teacher, you can scare people to death.“
"Scared you to death? You almost scared us to death. Feng Huadong thought.
Zhou's conjecture, a difficult problem that had plagued the mathematics world for more than ten years, was actually solved by a high school student. When he heard this news, he was almost scared to death.
No one would have thought that a high school student could actually prove Zhou's conjecture.
I scared you to death? Haha…what a joke.
"Hurry up and do the questions!" With a shout, Feng Huadong turned around and left.
"Are all the invigilators nowadays so fierce?”Zhou Luo shook his head and threw himself into solving the problem again.
A few minutes later, Zhou Luo started writing again.
"Damn it, why is it so difficult? "In the corner of the auditorium, Bai Chong held his head with both hands, his face ashen.
He solved the first question smoothly and only took half an hour to solve it. However, when he saw the second question, he was stunned.
What the hell was this?
The positive integral sequence (an)=1an 1=an-n1, ann. And an n, an Bai Chong was about to collapse. He had expected the test to be difficult, but he didn't expect it to be this difficult. This had already exceeded the content of high school! How could anyone do this kind of question? Bai Chong raised his head and looked at Zhou Luo. He wanted to see what Zhou Luo was capable of. However, in the next moment, his eyes widened. Zhou Luo was holding a gel pen in his hand and writing rapidly. "F * ck, that's impossible!" Bai Chong's eyes widened in disbelief. How could Zhou Luo write? Bai Chong was completely stunned. Originally, he was much more confident than Zhou Luo, but now Zhou Luo was actually writing furiously. Impossible, he must have written it randomly. He couldn't possibly be wrong. Bai Chong shook his head desperately and focused his attention on the answer sheet again. Suddenly, he had a flash of inspiration, and his eyes suddenly became clear. He found the way to solve the problem. He didn't have time to think. He quickly picked up the pen and began to write. In just half an hour, he had already solved the answer. " Hmph, you're still too inexperienced to fight with me." Bai Chong raised his head and revealed a smug smile. In just an hour, he had already solved two problems, which could be ranked high in the history of couplet. Unfortunately, in the next moment, the smile at the corner of his mouth froze on his face. "Teacher, hand in your paper." Zhou Luo raised his hand and said. It had to be said that this set of test papers was very good. Even though Zhou Luo was already at Level 4, it was still difficult to solve the questions. It took Zhou Luo nearly an hour to solve the answer. If it were anyone else, this would be impossible. Unfortunately, it met Zhou Luo. Zhou Luo was determined to win the gold medal this time! Hand in the paper? This sentence was like a bolt from the blue that shook everyone until they buzzed.
