Chapter 15 Taylor's Formula for Binary Functions
To be honest, although it is not the first time to become the focus of everyone and the center of the field, but this time it is really a little different, Liu Feng is really a little unaccustomed, after all, this time he is standing on the podium, and he may have to stand for a whole class next!
Speaking of which, this is also his first time.
I'm still a little nervous!
Stand up, we can't coax.
Liu Feng straightened up and walked to the center of the rostrum, thinking that after this time, his buddy would become a popular figure on campus, he was still very excited to think about it.
After all, who has ever seen a freshman who dares to give a high math class on stage? Moreover, he is still a 24K pure "scumbag" who has hung 5 out of 6 courses!
"Ahem~" Pretending to cough twice, Liu Feng picked up the microphone.
"Good morning, ladies and gentlemen. Let me introduce myself, I am Liu Feng from Yinghua 0907 class, and I am the one who everyone was more or less grateful to me before. ”
A short self-introduction and complaining caught everyone's attention.
Seeing that everyone was attracted by their chic charm, this product nodded with satisfaction, it seems that the buddy's self-introduction is still very level!
But it's still quite strange, when he first stepped on the podium, he was stared at by a group of classmates in the black pressure in the ladder classroom, and his nervousness disappeared in an instant, but he felt a little excited, yes, excited!
"I guess I was born to be the kind of person who is in the limelight!" thought to himself.
"Shh~!"
Liu Feng had just finished his introduction, and in the classroom, suddenly a group of scumbags who were not afraid of big things to watch the excitement actually whistled to express their support for his opening speech.
Damn, buddy is so popular?
Liu Feng raised his eyebrows at the whistling classmates, but these people must be scumbags, dare to disturb the order of the class, and they will definitely give you a good look later!
What a stingy guy, and besides, he doesn't understand psychology.
You know, as a representative of the scumbag, he was fortunate enough to stand on this podium as a lecturer, what kind of experience is this? It is simply a representative of the scumbag and a model of counterattack!
There are already buddies who have prepared the microphone, and they are going to interview him after class.
"Thank you for listening, here, first of all, I would like to thank Mr. Yan for giving us such a chance to perform......" laughing at himself, Liu Feng teased Mrs. Shi again.
"Ahem~" Yan Shan on the side almost blew up her lungs, her chest trembled and she almost struggled to come out, how could there be such a strange student!
The exterminator's face was as black as the bottom of a pot, but when she thought that this thing was a stone in a pit, smelly and hard, she understood a lot.
When the students in the classroom heard this, they opened their mouths wide one by one, this thing is too bold, and they even dared to tease the extermination teacher, and suddenly exploded again.
"Shh~"
"Dude, awesome!"
"Dude, let's organize a group to burn paper for you today next year!"
There was an uproar......
"Burn paper, who, who said it, see if I don't kill you Y!" Listening to the noise of his classmates, Liu Feng secretly slandered in his heart.
"It's so thick-skinned!" Zhuo Tingting, who was sitting in the third row, was very anxious, and almost laughed out loud when she heard Liu Feng's words of thanks, this person is really interesting.
"Yes, yes, this guy is too good, you must leave his contact information after class later!" Sun Xiaoxiao on the side also widened her eyes, revealing an unbelievable look, as bold as she could only behave in front of the exterminator, how dare this buddy!
The female classmates of class 7 were even more red-cheeked, and they didn't dare to look at the classmates in his class, it was over, Liu Feng's classmates were too bold, why didn't they find out before?
Several animals in the 509 dormitory opened their mouths wide, and they could almost swallow a goose egg, yes, Fengzi, you are so awesome, you dare to go further and further on the road of death!
Seeing the exterminator with an iron face, classmate Shi Shang drew a cross on his chest, and couldn't bear to look directly at him and prayed, Fengzi, Fengzi, may Brother Chun bless you, Amen!
"Silence!" The situation became bigger and bigger, Yan Shan finally couldn't help but stand up, and her eyes were full of murderous eyes.
Like a mouse seeing a cat, for a while, the temperature in the classroom dropped several degrees sharply, and all the students couldn't help but shiver and quieted down.
There was a moment of silence.
"Classmate Liu Feng, if you don't know how to lecture, just say it, classmates are not here to listen to you talk about stand-up comedy!"
Yes, the exterminator was too orderly, so Liu Feng had no choice but to close his mouth and get straight to the point.
"Ahem~" shifted the embarrassment.
But you keep saying I can't give lectures?
Brother is already a high-level math two upside down existence, it's not that I'm bragging, everyone here is rubbish, including...... Eh, Mr. Yan, except for you.
So, I'm going to take a lesson to tell you about today's content - Taylor's formula for binary functions. Dear students, please turn to page 58 of the textbook......"
Yan Shan thought that after Liu Fengpi's two sentences, she would definitely not be able to talk about it, and then she would be able to clean up the mess, but she thought that this thing completely disregarded her own kindness, and really began to gush.
Touched his forehead helplessly, this guy is really going to fight with this seat to the end!
After all, although she was angry just now, she had already given Liu Feng the steps, as long as she admitted her mistake and said that she couldn't talk about it, then she really embarrassed you on stage?
I didn't expect Liu Feng to be so faceless!
I'd like to see what you can say!
Yan Shan crossed her hands in front of her chest and sneered, after all, although she is a teacher, she is also a woman, and she is in menopause......
At the same time, there were people like Liu Weizhe who looked at Liu Feng with a sneer.
A clown jumping off the beam, this limelight is really outstanding!
But a dog-like thing, a scumbag, a pig with a green onion in his nose, and really thinks he's an elephant!
Of course, there are naturally people who care, such as Lao Meng, Shi Shang and other classmates, as well as Zhuo Tingting......
Although she became serious, Zhuo Tingting met Liu Feng for the second time, but she has always been peaceful, and she can't see other people's difficulties and ugliness.
Speaking of which, she belongs to the kind of person who has a non-contentious personality.
Sometimes when there is a conflict with others, she usually takes the initiative to back down, therefore, Sun Xiaoxiao sometimes teaches her that for some indiscriminate people, she should take the initiative to slap her to death so that she will never turn over, and then step on her corpse twice, so that she can relieve her anger, like you, I don't know how much I will suffer!
It's just that the nature of the country is easy to change, and it is not suitable to settle the dispute, where can the character cultivated since childhood be changed; plus she looks quite good, and her mind is so kind, there are always more people who protect her than those who bully her, so she is rarely injured.
In the classroom, everyone looked at Liu Feng with affection, hoping that he would make a fool of himself and hope that he would survive this catastrophe safely, of course, most of them were the kind of people who didn't think it was a big deal to watch the excitement, such as Sun Xiaoxiao......
Squeezed his eyebrows at Liu Feng for a while, that means that you should continue quickly, there is an old lady to support you, don't be cowardly! It's a pity that the flattering eyes are thrown to the blind man, and Liu Feng won't notice her.
Standing on the podium, Liu Feng's face was calm, and the content of the chapter on Taylor's formula for binary functions in his mind was turned out, and at the same time, he synthesized his own words, turned his back to the blackboard, and began to talk eloquently.
"Students, the content of this lesson is mainly divided into two parts, the first part: the binary function Taylor formula, including the content of the formula, theorems, as well as the proof of theorems and examples, etc., and the second part: the proof of extreme sufficient conditions, including theorems and proofs......"
For a while, the excitement was gone, and the impetuous mind quieted down, and only Liu Feng's mellow and full lecture voice remained in the classroom.
A few minutes passed, and Yan Shan's brows gradually relaxed, because, involuntarily, everyone in the class, even Yan Shan herself, was taken up by Liu Feng, followed his lecture, and slowly immersed herself.
"What!"
Liu Weizhe also flipped through the textbook, and at the same time turned the pen in his right hand in a dashing manner, while following Liu Feng's lecture ideas, nodding from time to time.
Suddenly, he suddenly reacted, he came to see Liu Feng's jokes, not to listen to the lecture of the 'scumbag'!
Liu Weizhe was shocked, what happened to him just now? What happened? A college bully listened to a college scumbag talk about high math two, and it didn't make people laugh to death when he said it!
Damn, Lao Tzu was actually brought to the rhythm by this goods!
Liu Weizhe became indignant.
