Chapter 11 Super Difficult Math Olympiad Problems

In the afternoon, two English and two physics sections. Cheng Nuo spent almost all his time studying his superpowers.

After this morning, Cheng Nuo felt that his superpowers were not that useless.

Your own eyes can digitize everything, while your own brain has the powerful and accurate computing power like a computer.

With the cooperation of the two, many things can be accomplished.

For example, if you want to go somewhere, your brain will calculate the most time-saving route based on the various sets of data provided by Cheng Nuo.

If the body wants to complete a certain action, the brain can also give the most time-saving and least energy-consuming muscle movement.

Moreover, with the help of the data in my mind, Cheng Nuo's control of his body has reached an extremely accurate level.

If you want to use 5 bulls, you won’t use 5.1 bulls.

If you want to jump to a height of 0.2 meters, you won’t jump to a height of 0.19 meters.

If you want to run at a speed of 10 meters per second, um... forget it. The superpower has not changed Cheng Nuo's physique, he is still the weak chicken who can only run at 14 seconds in a hundred meters.

In addition, Cheng Nuo found that in addition to mathematics, physics and chemistry, two disciplines that deal with numbers and data, Cheng Nuo can also easily solve problems in related disciplines. Whether it is simple or difficult, Cheng Nuo just glances at it and can basically figure out a clear idea of ​​solving problems.

This discovery made Cheng Nuo happy for a long time. Academic master, I am indeed the life of a top student, haha!

However, this superpower is of no use to the three subjects of English, Chinese and biology, which makes Cheng Nuo feel very regretful.

Isn’t it said that if you learn mathematics, physics and chemistry, you won’t be afraid of traveling all over the world! It would be great if you only take the three subjects of mathematics, physics and chemistry in the college entrance examination.

Alas, I can only hope that this college entrance examination Chinese English biology is not too difficult.

As for mathematics, physics and chemistry? Hehe, naturally the harder the better!

At this time, in the Mathematics Group Office, Lao Tang frowned and fell into deep thoughts with a test paper.

The signature of the test paper is Cheng Nuo...

……………………

"Cheng Nuo, Lao Tang is looking for you." Before evening self-study class, mathematics class representative Jiang Qingqing returned to the classroom with a stack of test papers.

"Looking for me? What's the matter?" Cheng Nuo was a little trembling when he heard Lao Tang's name.

Could it be that Lao Tang knew about the canteen at noon? But the fight didn't start. Lao Tang wouldn't come to me because of this!

Jiang Qingqing was holding the morning exam paper. While she was sending the test papers to her classmates, she answered Cheng Nuo's words, "I don't know this, but looking at Lao Tang's appearance, it seems that it is not a good thing. Are you causing trouble again?"

Why did Jiang Qingqing say "again"?

Cheng Nuo is the kind of person who doesn’t make big mistakes and keeps making small mistakes. It’s not once or twice that Lao Tang calls him to the office alone.

In Jiang Qingqing's eyes, "The wind is whistling and the Yishui is cold, and the hero will never return once he leaves", Cheng Nuo goes to Lao Tang's office.

Sure enough, as soon as Cheng Nuo entered the door, he saw Lao Tang's stern face.

"Teacher, are you looking for me?" There was no choice but to bite the bullet and go.

Old Tang glanced Cheng Nuo with sharp eyes and sighed softly.

He took the test paper that Cheng Nuo did this morning, with a full mark on it, and the score of '150' on the front was extremely bright red.

"Is this what you did?"

Cheng Nuo looked at the test paper with his name clearly written on it and nodded, "Yes, isn't my name written on it?"

"I mean you did it yourself, are there any opportunities?"

As Cheng Nuo’s math teacher for two years, Lao Tang naturally knew Cheng Nuo’s math level. He could only say it was average, not good, and not too bad. But this test paper was definitely not something that Cheng Nuo could finish, and the full score was even more impossible.

Therefore, Lao Tang suspected that Cheng Nuo did it through some opportunistic methods. As Cheng Nuo’s math teacher and class teacher, Lao Tang felt it was necessary to stop such behavior in time.

Old Tang started the "Tang Monk" mode and taught Cheng Nuo with his straightforward and tempting voice.

"Cheng Nuo, I know your grades. I can understand your idea of ​​improving your grades, but you can't use those evil ways. With your grades, if you work hard during this period, you may not have no hope of getting into a key university...Bara...Bara...Bara..."

Half an hour later, Old Tang seemed to be a little tired and stopped to drink a sip of water. Cheng Nuo finally found the opportunity to interfere.

"Teacher, you have to believe me. I really didn't cheat in this exam!"

Cheng Nuo was also feeling distressed.

After Lao Tang talked for so long, Cheng Nuo understood what Lao Tang meant. Seeing that he got a full mark in this test paper, which was completely inconsistent with his previous performance, he suspected that Cheng Nuo was cheating.

Alas, if I had known this was the case, I wouldn't pretend to be this. It would be great if I finished this test paper according to my usual level!

Seeing that he had been teaching for so long, Cheng Nuo still refused to admit it and aroused anger for no reason.

He slapped the table and said, "No cheating! Since you haven't cheated, how did you do such a difficult question?! Don't tell me that your brain suddenly became clear. If your brain suddenly became clear, then try this question for me."

What math teachers lack the most is all kinds of strange and difficult math problems. In order to make Cheng Nuo give up completely, Lao Tang gave Cheng Nuo an Olympiad problem directly.

This Olympiad Mathematics question is not simple. This is a question in an Olympiad Mathematics Competition three years ago.

It is said that only more than a dozen people have done this question by thousands of students participating in the competition nationwide.

"As long as you can calculate this question here today, I believe you are not cheating!"

"real?"

"What I said is false?"

"But the last time your physical education teacher asked for leave, the result was..."

"Get out of here, go write quickly."

Cheng Nuo took the question from Lao Tang.

The distance from point T to four vertices in tetrahedron ABCD TA=a,TB=b,TC=c,TD=d, find:

1. The maximum volume value of tetrahedral ABCD and the conditions for taking the maximum value.

2. The maximum surface area value of tetrahedron ABCD and the conditions for taking the maximum value.

The questions give very few conditions and are very simple.

Cheng Nuo glanced at it, and for a moment, there was no clear idea in his mind.

It's difficult, this question is difficult! I don't know where Lao Tang got such a weird question.

For a moment, Cheng Nuo's attention was immersed in this question.

In my mind, countless letters and numbers were calculated back and forth, and a clear problem-solving idea gradually took shape in Cheng Nuo's mind.

When Old Tang saw Cheng Nuo standing there, he thought he had no idea at all.

So Old Tang pointed to an empty seat opposite him and said, "There is an empty seat over there, you can sit there and do it. It's 8:10 now, until 10:00. As long as you can calculate this question before 10:00. Of course, you can give up in the middle."

Seeing Cheng Nuo sitting opposite him, writing and painting on a piece of paper, Old Tang smiled faintly and stopped paying attention to Cheng Nuo and prepared his lesson plan.
Chapter completed!
