Wang Xueba System

Luo Hao felt like a cat scratching his head, the more he tried to suppress this thought, the more he rebounded.

Riding on the shared bicycle, Luo Hao was sparked with lightning all the way, running faster than an electric car. During the morning rush hour on weekdays, he quickly shuttled through the traffic flow.

Soon, Luo Hao arrived at the school gate.I took out my phone to check the time, and it took less than 10 minutes.After parking the shared bicycle, Luo Hao strode towards the library. He returned home yesterday because he still had problems to solve. Today, he has a new skill. Give it a try quickly to see if his answering speed has increased again.

In the library, Luo Hao once again sat in his usual seat.Because the principal had called in advance, the librarian would never clean up the books on this table.The books that Luo Hao put on the table yesterday are still there, and even the page numbers haven't changed.

"The motion equation of the known particle is: r=2ti+(2-t?)j, where the unit of r is m, and the unit of t is s. Find

(1) The trajectory of the mass point.

(2) When t=0 and t=2s, the position vector of the particle.

(3) From t=0 to t=2s, the displacement △r and the radial increment △γ of the particle.

(4) The distance s traveled by the particle within 2s. "

"Well, it seems that this question is not difficult at all now. The trajectory equation of the mass point is y=f(x), which can be obtained by eliminating /f from the two component equations x(f) and y(f) of the motion equation .For r, △r, △γ, △s, the physical meanings are different, and they can be calculated according to their definitions. The solution to s uses the integral method. Luo Hao quickly analyzed the question in his mind, muttering, "Well, that's right, that's it, so the answer to this question is..."

Luo Hao scribbled the steps to solve the problem on the paper, and in just a few minutes, he wrote the complete steps and answers to the problem.Luo Hao turned the exercise booklet to the reference answer page, with a smile on his face—all right!

Questions that I thought were a bit difficult yesterday, are now solved with ease.This skill is so powerful that Luo Hao can no longer express his feelings in Chinese alone. He can only express his admiration by superimposing Chinese and English—that's awesome!

In the short period of time just now, Luo Hao activated the two skills of strongest brain and brainstorming, and quickly flipped through the physics textbooks in the university.The effect of flipping through this time is completely different from before.

Every time I read it before, because the passive skill of photographic memory exists, the brain can indeed fully remember what it sees, but it is not certain whether it is fully understood.Although with the increase of Luo Hao's spiritual attributes and the slow development of his brain domain when using the strongest brain skills, his IQ is slowly improving.But he was just an ordinary person after all, and the system didn't immediately raise his IQ to a level that ordinary people can't match.All the knowledge he saw required him to understand and absorb it by himself.

At present, he has started to study university courses. Without guidance and tutorial books, he can no longer learn as casually as he learned in high school.

Luo Hao also thought about a solution. He looked up the best tutorial books on the Internet, and he bought them. However, he bought them online, but before they were delivered, he couldn't wait to start learning university knowledge.The result is self-evident, the head-on blow dealt a small blow to Luo Hao.

But it's different now. Under the joint use of the two skills, some simple problem-solving steps in the previous textbook have no secrets in Luo Hao's eyes.He was finally able to learn knowledge as easily as high school.

"Haha, hahaha——" Luo Hao suddenly laughed.

The librarian in the distance shrunk his neck, glanced this way, and muttered in a low voice: "It's over, a handsome guy, and he fell ill again. He's just like this at a young age, so pitiful."

"Uh..." Luo Hao, who was laughing, suddenly stopped, and looked around in embarrassment, "Huh, fortunately, there are no other students, or my image will be ruined. Only the librarian I'm a member..." Luo Hao turned his gaze to the librarian who was secretly looking at him.

Zhang Qingqing was a little flustered at this moment, the student who was not a few years younger than her just now suddenly laughed, and muttered something to herself, but he suddenly stopped laughing and stared at herself.

"He shouldn't have heard it?" Zhang Qingqing's heart was pounding, and it was fine to mutter those words to herself. If the Lord heard it, it would be over. "If he is really crazy, is it illegal to kill people? How should I run away?" ? Yes, run now. If he can’t catch up with me, he’ll be fine. No, I’m running now to prove that I’m guilty. If he didn’t hear what I said just now, I’ll be self-inflicted by running. Eh? No Ah, from such a distance, how could he hear it?"

In just a short moment, Zhang Qingqing filled up various situations in her mind.It has to be said that girls seem to be born with advantages over boys in some aspects.

"Hello, this teacher."

Suddenly a voice interrupted Zhang Qingqing's wild thoughts, looked up, was it him? !

After a while, Zhang Qingqing jumped up from the chair: "Ah, haha, what's the matter with that classmate?"

"Well, teacher, are you okay?" Luo Hao was a little dumbfounded, did he have something on his face?How do you scare people like this?

"Ah, it's all right, what's the matter with you, classmate?" Zhang Qingqing quickly waved her hands, feeling a little embarrassed, this can't be said, just now I was worried that you were going to kill me, right?

"Well, I'm sorry, I suddenly figured out a question just now, and I'm a little excited, please don't tell me about it, teacher, otherwise..."

"Ahaha, I understand. I will never say anything. Don't worry, classmate. My mouth is the strictest." Zhang Qingqing quickly expressed her attitude before Luo Hao finished speaking.A group of people panicked, "It's over, this lunatic has come to threaten me. If I want to speak out, he must kill people to silence him. I heard that it is not illegal for mentally ill people to kill people. Hey, he is so handsome and a good student. Are you crazy?"

"Well, that's really great. I'll go out for a while, and I'll treat the teacher to some fruit." Luo Hao didn't expect that the teacher looked weird, but he was so easy-going, so he, Luo Hao, couldn't treat him badly. , Buy some fruit for the teacher to eat, after all, the mouth of eating people is soft.

"Ah, classmate, you don't need to be polite." Zhang Qingqing was about to cry, and she was very anxious: what should I do, what should I do, this is the rhythm of poisoning me?
