- Boom!
A piece of chalk hit Chen Ling on the head.
Teacher Liao frowned and raised his voice a little.
"Tomorrow is the first consultation, everyone should cheer up. Just now I talked about a sub-point question, but many of you can't afford it. Let's continue to look at this question and find the distance between x-2y=0 The equation of the smallest circle"
Chen Xiao shuddered, and came back to look at everything in front of him.
A teacher wearing thick glasses wrote math problems on the blackboard, and the countdown to the college entrance examination was hung on the wall next to it-December 16, 1999, 205 days before the college entrance examination (the time for the college entrance examination in 1999 was July).
Chen Xiao was a little dazed, she just drank a little too much and stayed overnight in a hotel, why did she go to 1999?
Chen Xiao opened the somewhat mottled tin pencil case on the desktop, and illuminated himself with the reflective lining inside the pencil case.
The appearance is still the same, but much younger.
The name is still Chen Xiao, but the experience is completely different!
Before Chen Xiao was reborn, she resigned from a scientific research institution and started her own business, and finally became the boss of a technology group. She had already achieved her "small goal".
The memory of this body flooded into Chen Xiao's mind at once. And the current Chen Xiao, although his name and appearance are exactly the same as himself, but his life experience is completely different. Although his grades are good, his family is more difficult.
His father is Chen Qiang, an ordinary worker at the Jiangcheng State-owned Machinery Factory, and his mother, Lin Hui, has no job and sells some breakfast and stationery outside the machinery factory community. The family life is very tense.
Chen Xiao's parents before his rebirth, one was a university professor and the other was a doctor, died in a car accident very early.
The time is also completely wrong!
Before rebirth, Chen Xiao was only born in 2019!
If you use comparative metaphysics to explain, Chen Xiao was reborn in a parallel world, and the time and space were a little messed up.
Looking at this strange era, Chen Xiao was stunned!
He doesn't want to be reborn! This time, he changed from a big boss to an ordinary high school student, struggling from zero?
Chen Xiao was tired just thinking about it!
Mathematics teacher Liao looked at Chen Xiao who was distracted again, patted the table hard and asked, "Who can solve this problem?"
He has high hopes for Chen Xiao. Although this boy's family conditions are not good, he works hard and is a good seed for studying.
Mr. Liao waited for a long time, but found that no one raised his hand to answer, and the students looked at this question in a daze, not knowing where to start.
He called by name: "Chen Xiao, come up and explain."
Chen Xiao was still in a daze at the moment, but the teacher called his name, so he still walked up.
There is a math problem on the blackboard: [Assume that the circle satisfies: ¢ÙThe chord length obtained by cutting the y-axis is 2; ¢ÚIt is divided into two arcs by the x-axis, and the ratio of the arc lengths is 3:1. In a circle, find the equation of the circle with the smallest distance from the center of the circle to the straight line ¦É:x-2y=0.]
This question is very simple! In this era, the math problems in the college entrance examination in 1999 are much simpler than in my own era!
Moreover, Chen Xiao was originally engaged in scientific and technological work, so he still couldn't help himself with mathematics.
Chen Xiao picked up the chalk and wrote the answer on the blackboard: "Assuming the center of the circle is P(a, b) and the radius is r, then the distances from point P to the x-axis and y-axis are ©¦b©¦, ©¦a ©¦¡¡±
His chalk writing was smooth and powerful. After a few minutes, Chen Xiao finished writing the answer.
The classroom in the afternoon was very quiet, and everyone was breathing nervously in the classroom.
Teacher Liao stood behind Chen Xiao, and kept nodding while watching Chen Xiao's answer! As expected of a student whom he is optimistic about! The whole class can't do it, only Chen Xiao can!
And Shen Wei, a girl sitting not far in front of Chen Xiao, stared intently at Chen Xiao's problem-solving steps, and quickly compared her thoughts with her own.
Then Shen Wei bit her lip, took out her notebook and recorded all the solutions.
Shen Wei's deskmate, Su Qiao, had an uncomfortable expression on her face, and she didn't know what she was talking about.
When Chen Xiao wrote, the whole class burst into applause!
"It really is Chen Xiao! Only he can answer."
"This question is so difficult! I can't understand Chen Xiao's steps to solve the question."
Just when Chen Xiao was about to walk down, some information suddenly appeared in his mind.
[Influence +3, cumulative influence 3. ¡¿
[Technology tree: medical biology (not lit); physical and chemical machinery (not lit); computer information (not lit)??¡¿
[Remarks: If the influence increases to a certain value, one point of future technology can be unlocked, and 20 points of influence are required to unlock the first technology. ¡¿
Chen Xiao was a little confused.
Emotion itself not only came to 1999 with rebirth, but also brought the future technology system.
How can I increase my influence?
Just came to the podium to answer questions in front of many people, which made everyone amazed, which increased my influence.
If you get better grades in the whole class or even the whole school in the subsequent exams, will you be able to gain more influence?
In 1999, this was the eve of the big wind.
The stock market, real estate, bitcoin, and Internet technology have exploded. As long as you catch any of these outlets, pigs can fly into the sky.
Teacher Liao applauded happily and said, "Chen Xiao, you go down, remember to go to bed early at night, or you won't be energetic in class."
Chen Xiao still wanted to gain some influence, and said, "Teacher, I still have a solution."
What!
Not only Teacher Liao, but the whole class were shocked!
For such a difficult math problem, it is already amazing to be able to write a solution! Chen Xiao actually has a solution!
Shen Wei's hands were already frozen in the air, and she looked up at Chen Ling.
Su Qiao's face was even more ugly, and he was still thinking about what was going on with the solution Chen Xiao gave just now.
Chen Xiao continued to write on the blackboard: "Solution 2: Treat it as a quadratic equation of b. Since the equation has real roots, the discriminant is non-negative, that is, ¡÷=8(5d2-1)¡Ý0 "
In five minutes, Chen Xiaoyang finished the second solution freely.
Teacher Liao was full of praise while looking at the second solution! This method is more ingenious and simpler than the first one, but the knowledge points applied should be more solid and changeable. This time Teacher Liao took the lead in applauding!
"Very good! Our classmate Chen Xiao is really good! Mathematics is not a simple calculation, but a way of thinking. Please actively learn from Chen Xiao!"
The students discussed endlessly:
"It's amazing! If Chen Xiao's English is better, she can go to the top of the college entrance examination."
"Mathematics master! It's amazing!"
Shen Wei kept watching Chen Xiao return to her seat. She fiddled with her fingernails, feeling very uncomfortable. Why couldn't she even know how to solve it?
[Influence +6, cumulative influence 9.] ¡¿
Jiang Wei, the buddy behind him, also gave Chen Xiao a thumbs up: "Xiaozi, you are really awesome!"
Teacher Liao continued to teach, but Chen Xiao didn't listen.
He took out a notebook and recorded some important things on it. If the history of this world is basically the same as that of his previous world, even if the level of technology is not the same, some outlets will definitely appear.
He recalled what he had learned from reading news and biographies, and wrote down some important things: the establishment of Penguin, free 361 anti-virus software, real estate reform, Ali¡¯s online sales, the birth of Pingguo mobile phones, and the history of A-shares.
