Chapter 6-Give You a Special Room
Chen Fan returned to the classroom gloomily and sat in his seat.
"Your parents are here?"
"How did you know?"
Chen Fan looked at Ye Lulu.
"I just sneaked into the washroom and saw it. What's wrong with you?" Ye Lulu said. Did you secretly write a love letter to someone?”
"F * ck off, how can I still be in the mood to write a love letter now? Forget it, you don't understand. You'll know when you study at night. My eyelids have been twitching, and I keep feeling that something's not right.”
After dinner, it was time for evening self-study. During math tutoring class, Mu Wanqing said, Chen Fan, come out for a moment."
Sure enough, it started.
After walking out of the house, Mu Wanqing said,"Take your paper, pen, and paper and go to the math team. Team Leader Huang wants to teach you math.”
Chen Fan looked at his homeroom teacher helplessly and whispered,""Teacher, I'm worried that I'm not capable enough to learn it.”
"Not willing?"
In the end, Chen Fan compromised. He didn't care anymore. He would just go along with it. He would teach and learn if he could. The examination was still in his own hands.
Huang Youwei had already prepared a small yellowed notebook for the Mathematics team. He held it in his hand and looked at it carefully.
These were the exercises for previous imo math competitions, and they were all carefully prepared by Huang Youwei.
After seeing Chen Fan, Huang Youwei stretched out his hand and said,""Come, come, come. Sit by my side. I'll explain the math questions to you.”
Chen Fan nodded.
She was well-behaved and honest, just like a student who was really studying.
"Your question used a binary-based algorithm. This algorithm is not bad, but it's still not perfect.”
"Ah, what's a binary-system?"
Chen Fan pretended to be dumb, but Huang Youwei seemed to have been prepared for it. He chose to ignore Chen Fan's act.
From the mean value theorem, we have
(ak 1)k=(ak 1k1 1k1)k(kak(1k1)k1
√k)k=kk(k1)k1ak,
When ak= 1k1, the equal sign is established, where k= 2,3, n. So,
(a2 1)2(a3 1)3(an 1)n221a23322a3nn(n1)n1an=nn.
……
Chen Fan looked at the equation written by Huang Youwei and naturally knew what algorithm the old man used.
Inequality of the mean value.
The university chapters would often explain things, but high school also covered them. Of course, they didn't cover much.
The Mathematical Olympiad competition had an interesting setting. All the steps and methods required high school knowledge. If you used university knowledge, then you could only determine that there was a problem with your algorithm.
Anyone could learn advanced mathematics. Which of those who participated in the Mathematical Olympiad competition was not an expert among experts?
Learning mathematics was something that was common, but there was one thing that was very important, and it was not allowed to go beyond the curriculum.
However, Chen Fan was pinching his thigh hard because he was restraining himself.
This old man's solution was wrong.
Although the error was not obvious, there was an error in the data, and he still used the wrong data to calculate, which made Chen Fan very tormented.
There was another reason why Chen Fan was willing to listen.
Ding! Congratulations to the host for receiving guidance from an expert. Your understanding of mathematics is deepening.
Not bad, the system actually had other rewards.
"Your foundation is quite poor. You're pursuing too many novel algorithms. The foundation is the core of everything.”
This time, Chen Fan was not muddle-headed but listened carefully.
"The teacher doesn't have the ability to teach you. It's normal for you to control your marks and do the questions. However, that's how mathematics is. It's too common for students to be better than the teacher.”
Chen Fan stared at the question, his hands almost crushing his pants.
"What's wrong?"
"Uh, it's nothing, Teacher Huang."
"Oh, do you think there's a problem with my algorithm?”
"No, you wrote it…"
Chen Fan was really uncomfortable. Chen Fan, who had a mild obsessive-compulsive disorder, felt disgusted when he saw this kind of algorithm.
You clearly wrote down a wrong number at the beginning, but you still continued to write down.
He even saw the main point.
"Did I write something wrong?”
This old man was doing it on purpose. He was definitely doing it on purpose.
"I know that you have talent in mathematics and you can definitely get full marks. I don't care if you control your marks for fun or not, but there's one thing you have to know. If you participate in the competition and get zero marks, that would be embarrassing. It's normal for you to hope for an average score, to be stable, and not to be noticed.”
F * ck.
Endure, endure, restrain, restrain. This old man was provoking him. He definitely couldn't fall for it.
After Huang Youwei finished writing, he handed the paper and the thick notebook to Chen Fan.
"En, take it. You will participate in the competition in three days.”
"En, alright, Teacher."
After saying that, Chen Fan stood up. It was good that he finally did not have to see the wrong calculation steps.
"By the way, Chen Fan, did I make a mistake on that question? I feel that the value of k seems to be…"
"Aiya, teacher, I don't know what you're talking about. Isn't the value of k normal?”
"Is it normal?"
"It's normal…I think so. Teacher, I have a stomachache, so I'm going to the toilet.”
Huang Youwei laughed and watched Chen Fan leave.
