One afternoon, two English and two physics. Cheng Nuo spends almost all of his time researching his abilities.

After this morning, Cheng Nuo felt that his abilities didn't seem to be so frivolous.

Your eyes can digitize everything, and your brain has the power to calculate as powerful and accurate as a computer.

When the two work together, they can accomplish a lot of things.

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

If the body wants to complete a certain action, the brain can also give the muscle movement method that saves the most time and consumes the least energy to make this action.

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

If you want to use 5 N of force, you won't use 5.1 N of force.

If you want to jump 0.2 meters, you won't jump 0.19 meters.

If you want to run a speed of 10 m/s, you ...... That's it. The ability did not change Cheng Nuo's physique, he was still the weak chicken who could only run 14 seconds in 100 meters.

In addition, Cheng Nuo found that in addition to mathematics, physics and chemistry, which deal with numbers and data, Cheng Nuo can also easily solve problems in related disciplines. Whether it's easy or difficult. Cheng Nuo only needs to glance at it, and he can basically come up with a clear idea of how to solve the problem in his mind.

This discovery made Cheng Nuo happy for a long time. Xueba, I'm really still the life of Xueba, haha!

However, this ability is useless for the three subjects of English, language, and biology, which makes Cheng Nuo feel very regretful.

It doesn't mean that if you learn mathematics, physics and chemistry, you won't be afraid to go all over the world!

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

As for mathematics, physics and chemistry, hehe, the harder the better!

At this time, in the office of the mathematics group, Lao Tang was holding a test paper, frowning and falling into deep thought.

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

..................

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

"Looking for me, what's the matter?" As soon as he heard Old Tang's name, Cheng Nuo trembled a little.

Could it be that the incident in the cafeteria at noon was known to Lao Tang? But if there was no fight, Lao Tang would not have come to me for this incident!

Jiang Qingqing was holding the test paper of the morning exam in her hand, and while she asked her classmates to send the test papers, she replied to Cheng Nuo's words, "How do I know this, but looking at Lao Tang like that, it doesn't seem to be a good thing." Are you causing trouble again?"

Why did Jiang Qingqing say "again"?

Cheng Nuo belongs to the kind of person who does not make big mistakes and keeps making small mistakes. was called to the office by Lao Tang alone, not once or twice.

In Jiang Qingqing's eyes of "the wind is sluggish and the water is cold, and the strong man will never return", Cheng Nuo went to Lao Tang's office.

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

"Teacher, are you looking for me?"

Old Tang glanced at Cheng Nuo up and down with sharp eyes, and sighed softly.

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

"You did this?"

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, was it opportunistic?"

As Cheng Nuo's mathematics teacher for two years, Cheng Nuo's mathematics level is naturally clear to Tang. It can only be said that it is average, not good, and not too bad. But this test paper is definitely not something that can be completed at the level of Cheng Nuo, and a full score of 10,000 is impossible.

Therefore, Lao Tang suspected that Cheng Nuo had done it in some opportunistic way. As Cheng Nuo's math teacher and homeroom teacher, Tang felt the need to stop such behavior in time.

Old Tang opened the "Tang Seng" mode and taught Cheng Nuo with a gentle voice.

"Cheng Nuo, I know your grades, and I can understand your idea of wanting to improve your grades, but you can't use those crooked ways. With your grades, no matter how hard you work during this time, you may not have any hope of being admitted to a major university...... Let's go...... Let's ......."

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

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

Cheng Nuo was also bitter.

Lao Tang has been talking for so long, and Cheng Nuo also understands what Lao Tang means. Lao Tang saw that he had scored a full score on the test paper this time, which was completely inconsistent with his previous performance, so he suspected Cheng Nuo of cheating.

Hey, I knew that this was the case, so I didn't pretend to be forced to do this, and I finished this set of test papers according to my usual level!

Old Tang saw that he had been teaching for so long, but Cheng Nuo still refused to admit it, and a wave of anger rose for no reason.

He slapped the table and said, "You didn't cheat, and since you didn't cheat, how did you do such a difficult question?" If your mind suddenly opens up, give me this question a try. ”

The most important thing for math teachers is a variety of math problems of strange difficulty, in order to make Cheng Nuo completely dead, Lao Tang took an Olympiad math problem directly to Cheng Nuo to do.

This Olympiad problem is not simple. This was a question from a math Olympiad three years ago.

It is said that out of the thousands of students across the country who participated in the competition, only a dozen or so made it.

"As long as you can figure it out here today, I'm sure you're not cheating!"

"Really?"

"What I said is still false?"

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

"Fuck off, hurry up and write. ”

Cheng Nuo took the question from Old Tang.

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

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

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

The conditions given in the question are few and simple.

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

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

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

In his mind, countless letters and numbers kept calculating back and forth, and a clear solution idea gradually took shape in Cheng Nuo's mind.

When Old Tang saw Cheng Nuo, he stood there stunned, thinking that he had no idea at all.

So Old Tang pointed to an empty seat opposite him and said, "There's a vacant seat over there, you can sit over there and do it." It's 8:10 a.m., and it's 10 a.m., as long as you can figure it out before 10 a.m. Of course, you can also give up halfway. ”

Seeing Cheng Nuo sitting opposite him, writing and drawing on a piece of paper, Old Tang smiled faintly, stopped paying attention to Cheng Nuo's side, and prepared his own lesson plan.

This kid will give up in less than half an hour!
