"Shen Qi, 715 points!" Gu Xiaodan from the third (2) class of high school was amazed, and the score ranking table in his hand was exactly the same as Shen Qi's: "There is nothing new in mathematics full score." Li Zong 290, Chinese 133, English 142, Shen Qi, how can you do this? Do you want the whole subject to crush us? You have been sent to Yan University, why do you still have to take the exam!"

"If I can't take the college entrance examination, I always feel a little regretful about my high school career. Shen Qi said.

"All-discipline dominant, Shen Qi, this is the rhythm of winning the champion?" Chen Xiaoting has been alone at the empty table for twenty years, and finally welcomed back to the same table of the top student.

Shen Qi pondered for a while: "Champion is such a thing...... Yes, there can be. ”

"People with 518 points don't speak, and they are dumped by you for nearly 200 points. Gu Xiaodan said.

"People with a score of 520 said that this kind of thing is too far away from us. Chen Xiaoting said.

Shen Qi looked at the ranking list: "Gu Xiaodan scored 112 points in mathematics, Chen Xiaoting scored 101 points in mathematics, in fact, Xiaoting's Chinese and English are okay, and there is no pressure in the mathematics test for more than ten or twenty points." ”

In the past ten years, the admission line of the college entrance examination in Nanyue Province has a characteristic, and the admission score line of liberal arts is generally higher than that of science.

This summer, Nanyue Province drew a liberal arts line with a score of 535 and a science line with a score of 522.

Last year, it was even lower, with a score of 510 in the liberal arts line and 485 in the first science line, which was not even 500 points.

Counting a few years ahead, the score line should be higher, and the line of liberal arts and science will go to 550~580.

As far as science is concerned, if you score more than 600 points in the province, it is not much of a problem to go to Shuimu and Yanda. Score more than 700 points, this is the strength of the champion.

Chen Xiaoting sighed: "Hey, more than ten or twenty points, how can it be so easy to take the test?"

"I have to be able to get 120 or 130 in mathematics, and I don't have any pressure to go to a major university. Gu Xiaodan tore open an Oreo and handed it to Shen Qi: "Big guy, what about the math cheats you said?"

Shen Qi took out a biscuit and stuffed it in his mouth: "This time I went to the Yan University Mathematics Camp to receive education, let me pause, wait, at the end of this month at the latest, I will compile a first edition." However, I need Xiaoting and Xiao Dan as my assistants to complete this job with me. ”

"What can we do?" Chen Xiaoting and Gu Xiaodan said in unison.

Shen Qi: "Don't ask too much, just listen to my orders." ”

After returning home, Shen Qi immediately turned on the computer and entered writing mode.

Shen Qi did not operate according to the model of those tutoring books sold on the market, but used the style he was best at --- diary.

"My name is Shen Qi and I am a high school student. First of all, I'm not writing a math tutorial guide, you can think of it as a high school journal. ”

"This diary is based on math and interspersed with some bits and pieces of my high school career. ”

"I don't use any jargon outside of my high school syllabus because it's just a journal. ”

......

"Plane vectors are both algebraic and geometric, and are a great example of the combination of numbers and shapes, and they are used throughout high school mathematics. ”

"In my opinion, vector is a tool, yes, it's a tool, ubiquitous, everyday, like a kitchen knife in the kitchen. ”

"For example, take a look at the next question. ”

"In the planar Cartesian coordinate system xoy, the known vector μm = [root number 2/2, - root number 2/2]. ”

“ιn=（sinx，cosx）。 ”

“x∈[0，π/2]。 ”

"(1) If μm ⊥ιn, find the value of tanx. ”

"(2) If the angle between μm and ιn is π/3, find the value of x. ”

"This question is universal, and if I can't give the correct answer within 3 minutes, I'll lose. ”

"It's actually very simple, I only have two kitchen knives in my hand, one is called 'linear representation of vectors' and the other is 'quantity product'. ”

"Is it because Shen Qi's knife is not fast, or are you floating again on the math problem?"

"It doesn't matter if you float or not, I have two kitchen knives in my hand, and you call you Dad. ”

"Based on the operation of the quantity product under the coordinate representation, I take the following steps:"

“@@##@@！@@@......”

"This step can be universal, and at any time, we should not throw away the two kitchen knives in our hands. ”

"Look, the penultimate question in the college entrance examination last year was cut into a dog by me in 3 minutes. ”

"And you, with a little practice, can do it. ”

......

The more Shen writes, the more he writes, and he uses his own unique language to explain trigonometric functions and vectors, which he considers to be one of the most important parts of high school mathematics.

There are no tricks to win, and the college entrance examination does not need the Yitian Sword and the Dragon Slayer Knife, all that is needed is a stainless steel kitchen knife.

Kitchen knives, folk artifacts, after a little practice, everyone can skillfully use them to chop melons and vegetables.

The most important thing is the knife technique, and the difference between a top student and an ordinary student is reflected in this.

Shen Qi made himself temporarily forget about high mathematics and high generation, and he used pure high school mathematics language to compose a kitchen knife knife method heart sutra. This was summed up by himself, and the guidance of Professor Sun of the Mathematics Camp of Yan University gave him a lot of inspiration.

wrote nearly 10,000 words in one night, Shen Qi's code word speed surpassed that of many Internet writers, and some writers could write seven or eight thousand words or even less after a whole day in front of the computer.

The main reason is that Shen Qi is very familiar with this field, and it can be said that he comes easily, so his hand speed is fast.

In the process of compiling the diary back to basics, Shen Qi's understanding of mathematics was further deepened, Zhang Wuji had no tricks to win, Qiao Feng obviously knew how to descend the dragon and eighteen palms, but he relied on the most basic set of hundreds of people who were beaten by Taizu's long punch to call Dad.

Therefore, the real master plays with internal force and consciousness, and it is also applicable to mathematics horizontally.

Shen Qi printed out the Heart Sutra written tonight, and printed two copies of the five sheets of A4 paper on the front and back.

At five o'clock in the morning the next day, Shen Qi got up and rode to school.

The first semester of the third year of high school was very hard, and at six o'clock in the morning, all the students of the third (2) class of high school sat in the classroom, except for Xu Rui.

Shen Qi and Xu Rui are two special personnel, one was sent to Yan University, and the other gave up cultural classes to pursue sports.

During the morning self-study, Shen Qi handed over the two Heart Sutras he had written by himself to Chen Xiaoting and Gu Xiaodan: "You two use the time of morning self-study to read it, and you can understand as much as you can." Give me feedback after reading it. ”

"This ...... This is the legendary Shen's knife technique?" Gu Xiaodan quickly scanned the Heart Sutra and found that the word "kitchen knife" appeared frequently.

"Poof, diary style, that's creative. "Chen Xiaoting is most afraid of reading those math tutorial books, which are boring.

Shen Qi's diary style solution guide, the writing is not very good, high school students' composition level, but the language is particularly vivid.

Chen Xiaoting and Gu Xiaodan immersed themselves in studying the Heart Sutra written by Shen Qi.

After the morning self-study, Gu Xiaodan said strangely: "I, I understand?"

"I ...... I seem to understand a seven-seven-eighty-eight?" Chen Xiaoting said suspiciously.

Shen Qi handed Chen Xiaoting and Gu Xiaodan a blank piece of paper: "Based on the content of this 10,000 words, where do you understand and where you don't understand, write them all on the white paper for me, and give me feedback before noon." The feedback from both of you is important to me because you are the most representative of the people. ”

Gu Xiaodan: "That means our math grades are terrible." ”

Chen Xiaoting: "Isn't it rotten?"

Shen Qi: "I don't think you two have any hope of getting a full score in the math test in this life, but it doesn't matter, as long as you can score more than ten or twenty points in the college entrance examination math, I believe it will also help you." ”

"Very helpful!"
