Chapter 115: Assault

The milk tea on the table braved the heat, and the floor-to-ceiling windows swayed in the wind.
Lin Zhaoxi stared at the tea cup for a while, feeling that the library air conditioner might be too big, she was blushing hot.
The pause was too long, and Lin cried a "cough": "The story of this movie is probably like this... In the future, there is a mechanism to stop crimes, subverting our current mechanism of punishing criminal acts that have already occurred... ..."
"Ok."
"This institution uses some means to arrest people who want to commit crimes but have not committed criminal acts."
"What should I do?"
"Through the three 'prophet', um... three people who can perceive criminal intentions, they will balabal say a lot of ambiguous things every day... then the crime prevention team can read their 'prophecy' and stop it in advance crime……"

How much has the crime rate been reduced?


The crime rate of serious crimes has dropped by 99.8%. There have been only one murder in five years.

After a moment of contemplation, he said: "It is really metaphysical."
Lin did not know how I suddenly thought of this movie, but since I said it, I have to continue to talk. She swallowed and tried to ask: "Do you think that through mathematics, is it possible to As you said in this story, calculate when the future... what will happen?"
Holding up the milk tea, Lin Chaoxi is waiting for it.
"This is a big proposition." After thinking seriously, he answered her.
"Or simplify this problem..." Lin rushed, "For example..."
"What is it like?"
"Well..." It was too clever, and Lin Chaoxi suddenly decided to play with it. "If you give an example, I can't think of it."
"For example, if there is a criminal, we know that he has the intention to launch a terrorist attack, but we do not know the specific location and location of the attack."
"Well, that's it. If you want to use mathematical methods to calculate it, what kind of knowledge do you need... Learn from calculus?"
"This order should be, univariate calculus, linear algebra, probability theory, multivariate calculus..." 裴 裴 ,






















"Oh……"
"With the computer, there should still be hope."
Lin’s eyes lit up, yeah, she seemed to have missed a great tool.
"Is the date of the first day of the new year?" Suddenly, a long sigh came from behind.
Lin slammed back, and Lin didn't know when to stand behind. She was shocked and she was really scared.
"We are exploring some issues." It is very calm.
"what is the problem?"
"You follow me!" Lin Chaoxi made a guilty conscience, interrupted the sorrow and Lao Lin.
"What is this?" Lao Lin laughed.
"You follow me to the library."
"How can I call the front foot and the back?" Lao Lin dragged a chair and sat down at their table. "And it is clearly my first appointment with the sly."
Lin Daixi was picked up by a milk tea: "Cough!"
When I handed the paper towel, Lin Chaoxi wiped her mouth: "Is it a big New Year's day carrying me to secretly open a small stove?"
"Master..." He said with some helplessness.
"I called her, she said something, let me play alone." Lao Lin said.
Lin Zhaoxi lived, it seems that there is such a moment, she and Lao Lin finished breakfast, Lao Lin asked her what arrangements are there today, whether or not to spend the festival together...
She said: No, I have something...
"So what do you call us to the library today?" Lin asked.
Lao Lin: "It’s so straightforward to transfer the topic, and Dad can’t really answer you."
"..." Lin Xixi, "I am sorry."
"It's ok."
Lin Zhaoxi: "..."
"I will complete your New Year's wish." Lao Lin said.
Looking at the face of Lao Lin "Daddy knows everything", Lin Chaoxi’s heartbeat was leaking nervously. She didn’t know what she was exposed.
"What are you saying?"
"New Year, don't want to listen to Dad's teachings seriously, don't you want to learn calculus?" Lao Lin smiled and looked very proud.
Lin Zhaoxi, she felt that she should be moved. She asked Lao Lin too many questions like this. Lao Lin was on the mind and found her thoughts through clues...
But now, she has a strange sense of fate.
"I will study hard," she said very seriously.
Lao Lin snorted and turned to look at it: "Give her a few questions?"
I don’t know why.
"It's awkward for her."
Hearing here, Lin is still awkward. He knew it. He nodded and took out a blank sheet of paper and pencil from his bag. He really started to ask questions.
Lin Zhaoxi stunned forward, not knowing what Lao Lin and Yu Zhi are doing, only to sneak a peek at the classmates.
The first question is factorization, which is very basic. The mental arithmetic gave the answer, and Lin Chaoxi breathed a sigh of relief.
The second question is to find the root of the quadratic equation. The third question is an algebraic proof...
After the completion of the part related to algebra, the beginning of the function, and then the geometry, trigonometric functions, composite functions...
He held the pencil and wrote it in a steady and steady manner. Lin Zhaoxi watched him write a piece of paper, then went to get another one, and he did not care.

What's the idea?
asked Lao Lin.
"this is……"
"A long delay can lie to Dad's answer?"
Lin Zhaoxi: "..."

Is this the foundation?

"Specific point." Lao Lin said.
"The basics of middle school mathematics that should be mastered before studying advanced mathematics."
"Although you learn math in middle school, and university math..."

It’s basically okay,
Lin added to the evening.
I will still be brave enough to answer questions.

"But?" Lao Lin wants to start a turning point.
"But you have to know clearly why it doesn't matter between them."
It’s hard to raise my mouth, probably because she thinks her answer is very old.
Lao Lin nodded in an understatement and asked the questions he had taken.
Lin Zhaoxi discovered that, unconsciously, he wrote a full three-page title.
There is proof of differentiation, and there is a very complicated function problem...
"This question is very interesting." He explained it.
Lin Zhaoxi: "..."
I was stared at by two people, and Lin did not even have the strength to resist.
The New Year's date is a question. She actually feels normal again. She picks up the pencil in front of her and says, "Give me some more blank paper."

For two hours, nesting in a small sofa in a small cafe, Lin was writing non-stop.
The topic of Qiu’s classmates is the same as his own. It is very regular and orderly, but it is also very deep. Some proofs that seem simple are really doing it, and they involve a lot of knowledge. She also needs to think carefully.
Unconsciously, time passed by, Lin eve immersed in it, and at the moment when she put down the pen, she sighed and felt that the college entrance examination might not be the case.
She began to organize the answer sheet on the glass table, turned it over from beginning to end, and then prepared to hand over the paper.
Lao Lin said: "Let's keep it, the meal is here, go to dinner."
After that, Lao Lin took the lead and ran off the chair.
Lin Chaoxi whispered to him: "What happened to Master, did you give me a batch?" She prepared to hand in the answer sheet and wait for the test.
"Master has been watching when you do."
"...so no problem?"
"Ok."
"What does he run?"
He continued to be helpless: "I want to go to the bathroom."
Lin Zhaoxi: "?"
I started to pack things up, and the heating in the small cafe was very good. Lin looked at the table on the eve of the night. After a while, I finally realized: she just immersed herself in the problem. Lao Lin actually looked at her nervously. How long did she do, Lao Lin How long have you waited?
Perhaps for Lao Lin, this is his most fancy test. It is especially important for the big test of mathematics knowledge in all middle schools, coupled with the new year's new weather and so on.
"Don't say it early!" Lin Chaoxi slammed his face, and the old man liked to engage in such a sudden attack. It was still very scary. She was glad that she had just done the problem seriously.
"Master said..."
"Say what?"
"I am afraid that you will know the problem, you will come to lie..."
"How do I be such a person?!" There is still a big cup left in the milk tea. Lin Xixi is very distressed to pick it up, and wants to drink and drink two more.
"Cold, don't drink." 2k novel reading network
