Chapter 013: The Cartesian Curve

The next morning, I got up as usual and walked to the kitchen to get ready for dinner. Found the bar empty. I remembered that Aunt Tang rested for a few days because of discomfort in her lumbar spine. I quickly packed my clothes and ran downstairs to the snack bar to settle breakfast.

Due to this unexpected situation, I was late for today. Unexpectedly, as soon as I sat down, Min Ling glanced at me, and I followed her gaze and saw two familiar figures limping in, like two walking mummies, and I couldn't help laughing.

"Haha, you two don't look like you're going to play, it's fighting."

"Don't talk nonsense, if you weren't absent yesterday, Zhou Jun and I would have been beaten so badly." Lin Ruofan said angrily.

"The South Side Stadium is really a wild stadium in the city, and even I have been conspired against in a hundred battles. Eh, Yo Yo..." Zhou Jun sat down and **.

"That's right, the experimental middle school is too violent, even the skinny Zhou Jun can't bear it, if it weren't for a few police officers practicing on the opposite field, I guess they would all change from playing to fighting." Wang Ziyao interjected coldly.

"Why do you seem to know very well, did you also pass?" Min Ling looked at Wang Ziyao.

"Yes, I'm here too, my original intention was to go over to see the handsome guys. As a result, hey, became a paramedic. The two of them were still helped by me to see the bone-set, and the two of them shouted louder in the bone-setting hall than the slaughtered pigs! Wang Ziyao imitated while laughing.

"Thank you, heroine, you don't have to show it off." Lin Ruofan glanced at her.

"Isn't it nice? There are both blue and red confidants. Looks like I had a really good time yesterday. I slapped Lin Ruofan's right hand with a plaster cast hard.

"To get back to the point, after class this afternoon, we are going to organize the first meeting of all class cadres, and Teacher Gao Ren has entrusted me and Sanfeng to inform. You are all part of the class cadres. Wu Minling looked at Lin Ruofan, Wang Ziyao and Zhou Jun.

It may be that the three words of the class cadre are too magical, which touched the nerves of Liang Tiancheng, who was far away from the 2nd row, he pretended to walk by casually, and then coughed dryly. "I heard you're going to have a meeting of class cadres?"

"It's not you, it's us." I circled my fingers around a few of them, including Liang Tiancheng.

"I, I'm got a part too?" Liang Tiancheng had a overjoyed expression.

"Not only do you have a share, you are also the most important member, you are a scholar, in charge of more than 10 class representatives in the class, and you are in a high position." Wu Minling hurriedly agreed.

Sure enough, Liang Tiancheng immediately put his finger against his frame, "I knew that the class couldn't lack a backbone like me." Don't worry, squad leader, I will serve you well and will not overstep my authority. ”

Lin Ruofan laughed "poof", "This student *** will shoot the squad leader's ass as soon as he comes, it's amazing!" Amazing! ”

Liang Tiancheng immediately blushed.

I raised my hand and motioned for Lin Ruofan to talk nonsense again, and I would give him a few more palms of the plaster palm.

"Don't talk about it, go back to your location and prepare for class, and we'll talk about the things in the class after class." Wu Minling waved his hand outward, signaling everyone to hurry up and return to their positions.

············

The first lesson of the day is math. Speaking of which, I must introduce our math teacher, whose name is Lu Baihui, known as Lü Buwei. She has a height of about 1.5 meters, a shoulder-length hairstyle, and her feet are sky-high, although her figure is not outstanding, her voice is full of soft taste. She often boasted in front of us that if she hadn't had a heart to teach and educate people, she would have devoted herself to the broadcasting career and become a DJ. Of course, Lin Ruofan's interpretation of her words is that if she is not only 1.5 meters tall and the radio station does not admit her, how can she come to school. By the way, I would like to add that the representative of the mathematics class is Guo Qin, which is said to be requested by Teacher Lu, because she eats Guo Qin's classmates very much, and of course, Guo Qin's mathematics scores are also among the best in the class.

Going back to the content of this lesson, this lesson is mainly about functions. Although it is a new class, in fact, most of the students have already taken classes in tuition institutions in advance during the summer vacation, so it is easy to be distracted, including me. I listened and began to travel in space, because Wu Minling and I were sitting in the last row, and the position by the window, it was simply a natural advantage of desertion, commonly known as geographical advantage.

I gossiped about what other classmates were doing, and found that Zhou Jun was secretly flipping through sports magazines, Wang Yongfa was reading comics, Wang Ziyao was reading fashion magazines, Liang Tiancheng was lowering his head to do questions, and the most outrageous thing was Lin Ruofan, who was directly fishing with his head half-propped up. I really admired these people, none of them were listening to the lectures, and of course I didn't get much better.

I looked sideways at Wu Minling next to me, who was taking notes carefully and highlighting the example questions in red. I finally saw one who was listening attentively. I looked at her unconsciously. The white hand holding the pen and repeatedly calculating on the paper, the rustle of the brushstrokes on the paper, and the faint smell of lavender emanating from her hair, I couldn't help but be fascinated.

She may have noticed my desertion and tapped my desk with a pen. "Be serious, don't affect me, I didn't sign up for classes to study in advance, Yu Dashao."

I felt embarrassed when she said this, and quickly turned my head out the window.

At the beginning of September, the leaves of the ginkgo biloba are yellowing and scattered on the campus with the wind. I looked out of the wall in a daze, and several ginkgo biloba leaves drifted to my desk in the wind. I picked up a piece of fiddling, put it in my notebook, and fanned it out with the edge of my pen.

When I put away my pen proudly, Wu Minling grabbed my notebook and wrote on the side: S fan = (lR)/2 (l is the fan arc length).

I immediately took back my notebook, wrote the incomprehensible style, and then wrote "Silver candle autumn light cold painting screen, light Luo small fan fluttering fireflies." The night is as cool as water, and you can sit and watch the morning glory Vega. ”

She was obviously not convinced, and said in a low voice: "This is a math class, even if you desert, you have to use the knowledge of this major." ”

Since it's a desertion, how can you still think about the content of this class, it's like skipping class to go to an Internet café to study for yourself, I can't imagine it.

She saw that I didn't pay attention to him, and whispered: "Actually, mathematics is also a subject full of romantic elements, don't think that only literature has charm." ”

"Yes, yes, passionate geometry calls for sexy functions, and we live a happy life of calculus together." I smiled and pandered.

"Prove you haven't heard of Descartes." Min Ling turned her head away from me and went about her exercises.

"Nonsense, the father of analytic geometry, a famous French mathematician, physicist and philosopher." I replied confidently.

"Oh, that's a good idea." As she spoke, she continued to bow her head and do her exercises.

I wondered if I was wrong, but the teacher at the tuition institution did introduce it like this. Is there anything that is not mentioned by the tutoring agency?

············

Finally, at the end of the day's class, according to the original plan, Mr. Gao Ren organized us to his office to hold a class cadre meeting.

As soon as he saw Lin Ruofan in plaster and Zhou Jun wrapped in gauze, he asked with concern, "Aren't you two fighting?" ”

Liang Tiancheng took the lead in replying: "Playing is playing, but it is just playing basketball, and I was taught how to play by the people in the experimental middle school." Hee-hee. ”

The corners of Mr. Gao Ren's mouth played, and he couldn't help but smile. "It's not a light tuition. To get back to the point, this time Min Ling notified everyone to come over to discuss the focus of the next work - the autumn outing, because the school's autumn outing is organized by the class collective, which is different from the previous inter-school autumn outing. Therefore, each class cadre must do his or her own duty to ensure safe travel and happy entertainment. ”

"It's true that the weather is perfect for going to the countryside, and it's better to go a little farther away." Wang Ziyao's excited expression was written on her face.

"This autumn tour is mainly a study tour, and I tentatively plan to go to Canghe Waterfall and Xuanwuzhuang in the next city for a study tour, do you have any objections?" Teacher Gao Ren looked at everyone.

"Canghe Waterfall is a famous landmark in Mingcheng, and Xuanwuzhuang is a place that literati and artists like to visit, which is indeed in line with the use of local education." Wu Minling analyzed.

"I'm okay with that." I think the same thing as Wu Minling.

"The two squad leaders have no opinion, and I have no opinion." Liang Tiancheng followed suit.

"Sanfeng has no opinion, and I have no opinion." Lin Ruofan said.

"I have no problem with Wang Ziyao, obey everyone." Zhou Jun teased the slightly disappointed Wang Ziyao's face, and Ziyao also nodded in agreement.

"Okay, that's a happy decision. Today is Tuesday, the initial departure date is next Monday, Yu Feng and Min Ling are in charge of hotel reservations, car contact, and local tour guide contact. Wang Ziyao is responsible for restaurant reservations and insurance purchases. Lin Ruofan and Zhou Jun were responsible for the discipline of the day's trip. Liang Tiancheng is responsible for the calculation and collection of expenses. Do you guys still have any questions? ”

After everyone looked at each other, they all shook their heads, "No opinion!" ”

"Then it's settled, adjournment!" Mr. Gao Ren was obviously satisfied with everyone's cheerful attitude.

"Wait a minute, Mr. Gao Ren, I have a proposal." Wang Ziyao mentioned in a whisper.

"What's the matter? Don't be shy, bring it up. Teacher Gao Ren looked at Zi Yao.

"I think this is our first official class cadre meeting, and it is rare for everyone to get together in the same class, so we should leave a memorial for this meeting."

"You want me to take a picture of everyone with my phone?" Teacher Gao Ren was about to rummage through the drawer to get his mobile phone.

Wang Ziyao smiled and continued, "No, it's better for us to all sign Lin Ruofan's plaster." As soon as she finished speaking, she raised her pen and wrote the three big characters 'Wang Ziyao' on Lin Ruofan's plaster.

"Wang Ziyao! I know you're not at ease! Lin Ruofan shouted.

Teacher Gao Ren took the pen, "Good proposal!" "Then 'Gao Renyue' appeared on Lin Ruofan's right arm.

Liang Tiancheng forcefully pulled Lin Ruofan's right hand to his side, and raised the word "Learn from Liang Tiancheng." Then he laughed with satisfaction.

Wu Minling wanted to continue mentioning it, but I snatched it quickly, "Mine is longer, let me mention it first." "After speaking, I will inscribe 'Lin Ruofan.'

= A

ccossi

θ’。

I handed the pen to Min Ling, who looked at my inscription, his face flushed, and then said, "Wu Minling ρ=a1-cosθ ρ=a1-si."

θ”

"Your inscription is really only understandable to you, I want to use the thinking of a physical and artistic student, I want to engrave it." After speaking, Zhou Jun didn't know where to take out the art knife.

As soon as Lin Ruofan saw Zhou Jun's art carving knife, he was immediately frightened and rushed out.

············

After a group of six of us said goodbye to our teacher, we walked back. The originally powerful return legion, due to the inconvenience of Lin Ruofan and Zhou Jun's movement, they called their family members to pick them up early in the morning. Wang Ziyao participated in the vocal training class and Liang Tiancheng participated in the cram school, but it turned out to be a duo between me and Wu Minling.

We walked side by side, our paces surprisingly consistent, and suddenly, Wu Minling reached out and stopped me, "Why did you pretend not to know the Cartesian curve during class?" ”

Looking at her angry expression, I couldn't help but laugh and reached out to stroke her head, "I really didn't lie to you, I didn't know the Cartesian curve before, but I can't bear to be laughed at by you for my ignorance, I hurry up and use it." After speaking, I took out my phone from my trouser pocket, "It was Du Niang who told me." ”

"Young Master Yu, really Niu X, you have to have a mobile phone at a young age." Wu Minling continued to flatten his mouth.

"By the way, do you have a cell phone? Hurry up and send me the number and I'll record it. I asked.

Wu Minling paused, "The little woman's house is surrounded by walls, where can such a valuable thing come from." After saying that, he smiled and accelerated forward.

I knew she was smiling like that every time she was trying to ease the embarrassment, and I blamed myself for my stupidity. I caught up, "Then why don't you leave me your home phone so I can ask for homework sometimes." I still asked cheekily.

"This is the worst excuse I've ever heard, you're the first in the class, and you still have to ask about homework, don't you want to laugh at the dead? Let's go, and when the old lady feels in a good mood, she will reward you. ”

"Good! I promise you'll tell me automatically soon! I smiled and held up the strap of my school bag. Rush to the fork faster than anyone! "After that, I pulled my legs and ran.

Wu Minling quickly chased after him from behind. In this way, we chased in the afterglow of the sunset, and the sound disappeared with the sound of the September wind, leaving only two silhouettes, one long and one short, chasing.
