Chapter 16: Slightly Attack Him
Galileo once said that mathematics is the language God uses to write the universe.

When Chen Xiaoxin saw that he had drawn the math skill, and it was one of the core skills, he felt like he had won 500 million. The indescribable joy and excitement was like a flood that burst from a dam, constantly hitting the embankment deep in his heart, stirring up huge waves that covered the sky.

this moment,
Chen Xiaoxin thought of the Prince of Mathematics Gauss, the King of Mathematics Euler, Newton, Pythagoras, Archimedes, and Riemann. And in this brilliant river of mathematics, he will definitely have his own mark, no... there should be many marks!

In the next second.
Countless basic mathematical knowledge flooded into my mind, and I felt like my brain was growing wildly!
He silently opened the system and glanced at his data panel.

【Name: Chen Xiaoxin】

[Intelligence: 96 (ordinary people)]

[Physical Strength: 61 (Disabled)]

[Agility: 82 (Ordinary People)]

[Student Skills: Classical Chinese (Lv1, improves classical Chinese level), Basic Mathematics (Lv1, improves basic mathematics level)]

[Assisted skills: Neural Perception (Lv1, improves the perception of the surroundings), Kirin Arm (Lv2, improves hand speed)]

【Slacking Points: 0】

It seems like my intelligence has increased by two points!

But why don't I feel anything?
After turning off the panel, Chen Xiaoxin took out his high school math textbook, turned to the part about functions, and randomly picked a question from the after-class exercises.

Chen Xiaoxin used to be very resistant to mathematics because he really couldn't understand it at that time. Although he memorized all the formulas and tried to apply them according to what the math teacher taught him, he couldn't find the answer in the end. Since then, Chen Xiaoxin has completely given up.

But at this moment.
He finally realized the joy of mathematics. It turns out that mathematics is so simple!

After doing several questions in a row, he knew how to do almost all of them after just one look. However, next, Chen Xiaoxin decided to try to increase the difficulty to see where the limit of basic mathematics at Lv1 is.

Test paper, test paper!

So many papers have been distributed, where should I put them?
Chen Xiaoxin searched the desk desperately, and finally, with his unremitting efforts, he found a set of college entrance examination simulation papers and turned directly to the last question. Questions like this are basically used to screen top students, and to decide which of them will go to Peking University and Tsinghua University, and which can only go to other universities.

So, it is not just difficult. Even if you have practiced tons of questions and can skillfully use all the so-called formulas, there is still a 99.999% chance that you will not get full marks for this question.

Before
Chen Xiaoxin didn't even want to take a look at it. When he was in a good mood, he would at most write a "solution". But now, he read the question carefully and tried to figure out the answer.

It seems like this question is just like that!
It only involves the calculation of derivatives, the monotonicity of derivatives and functions, and the zeros of derivatives and functions.
Chen Xiaoxin silently took out a piece of white paper and started sketching on it. He was so fast that only the residual image could be seen. From f(x)=(x-1)e^x-ax^2+b, we can know that the domain of f(x) is R, and f'(x)=e^x+(x-1)e^x-2ax=x(e^x-2a)
Chen Xiaoxin was working hard to solve the problem. At the same time, Yan Xiaoxi, a top student who was reading a book, inadvertently noticed his classmate Wolong next to him.

I rely on!

He. What is he doing?

Yan Xiaoxi couldn't help but widen her eyes and looked at her deskmate who was doing the homework in disbelief. The corners of her mouth trembled slightly, and her whole body seemed to be shocked to the point of being stiff and unable to move.

Doing questions?

Are you actually doing the questions?
Which grade in elementary school is this question for?

Wait, that’s not right! This seems to be asking for the monotonicity of the function f(x)!
Yan Xiaoxi knew what Chen Xiaoxin was doing just by taking a look at the problem-solving process, and the shock in her heart seemed like the collapse of the heavens and the earth.

From the analysis of the problem-solving process of Wolong's deskmate, this question is quite difficult, and it should be the final question of the college entrance examination. The key is that he actually used derivatives! And it is a very advanced derivative.

what's the situation?
How could he know such advanced derivatives?
Although high school mathematics does include the concept of derivatives, derivatives are not compulsory in high school. It is only one of the elective subjects, and it is not taught in great depth. However, this classmate of mine, Wolong, has a deep understanding of derivatives!

Just when Yan Xiaoxi was at a loss, Chen Xiaoxin successfully found the monotonicity of the function f(x) and began to solve the second problem.

Prove that there is only one zero.
simple!
Chen Xiaoxin picked up the pen again and quickly solved the problem on the white paper.

Yan Xiaoxi sat quietly beside him, watching him solve the problem. At this moment, she already knew how to solve it, but she wanted to see how Chen Xiaoxin solved it. However, Yan Xiaoxi was soon attracted by the beautiful waltz on the white paper. In the eyes of the top student Yan Xiaoxi, Chen Xiaoxin holding the black pen tightly was like a top dancer dancing a beautiful waltz on the white paper.

Why so fast?
Did it pass through the brain?
Yan Xiaoxi couldn't help but move forward and carefully looked at his problem-solving process. After checking it in her mind, she was horrified to find that it was actually... completely correct!

Right now,

Yan Xiaoxi's expression began to become serious.

Cool!
This feeling of sweating profusely!
It’s so cool!

Chen Xiaoxin looked at the densely packed derivation process on the white paper and realized for the first time how great it was to be a top student.

However, he did not feel proud of it. On the contrary, he had more respect for mathematics. Chen Xiaoxin understood that with his current ability, he was only at the level of a college student majoring in mathematics, and not even for the postgraduate entrance examination. As long as the difficulty increased, he would be completely unable to do it.

at the moment
The mathematical problem has been solved, so the next step is to move towards physics.

Open the system again and find the basic physics skills.

[Basic Physics (Lv1): Improves basic physics level, one of the core skills, essential skill for advanced physics]

[Conditions: Basic Mathematics (Lv1), IQ reaches 95]

[Price: 30000 Moyu Points]

All conditions have been met. In the next month, we should work hard to accumulate slacking points.

"Hey"

"Chen Xiaoxin."

Yan Xiaoxi lowered her voice and asked carefully, "Can you do this question?"

While talking,
A piece of white paper was pushed in front of him with a handwritten question on it.

Chen Xiaoxin looked at her with confusion on his face and said unhappily, "You are a top student, why are you asking me this?"

"."

"Stop talking nonsense and see if it works." Yan Xiaoxi urged awkwardly and impatiently.

"alright."

"let me see."

Chen Xiaoxin took the white paper and looked carefully at the question in front of him.

Yan Xiaoxi stared at him nervously. Seeing his serious and meticulous look, frowning from time to time, she suddenly felt happy.

No way?

I prepared this specially for you. There are no more than ten high school students in the country who can solve this problem!
snort!
As long as I take a little action, I will know your limits.

Just when Yan Xiaoxi was feeling smug, Chen Xiaoxin silently turned his head and looked at her with confusion on his face.

"So simple."

"you will not?"
