"Xu Xiaoshan, I'll establish that you should calm down and listen carefully. Pen %Fun %Pavilion www.biquge.info" Wang Hao, who was at the same table, sighed at this time and patted him on the shoulder inexplicably.

Xu Xiaoshan was persuaded to be stunned, and he wanted to attack Ye Ming, but when he found that no one cooperated, he couldn't help but be puzzled for a while. Just now, he was patronizing and thinking about how to hit Ye Ming, but he didn't pay attention to what Ye Ming said in his speech, and naturally he didn't know why his classmates were sitting in such a precarious position with such a drastic change in demeanor.

Hmph, it's just a bad student, what's the big deal, I'd like to hear what you said that shocked everyone so secretly.

As the class leader, Xu Xiaoshan has always considered himself a learning model in the class, so as soon as the previous unit ended, he first previewed the knowledge of part of the number series.

Not to mention, the number series looks easy, it seems that it is just a number comparison, but as soon as Xu Xiaoshan started the test questions, he immediately found that this matter is not so simple.

It is worthy of being one of the key academics of high school mathematics, a simple number arrangement, but it involves multiple areas of thinking, if there is no famous teacher to teach and explain, the average person is to ponder a three or two days can master the know-how.

But this is just a relative to ordinary people, is he Xu Xiaoshan an ordinary person? He is one of the ten geniuses recognized by the school! As early as yesterday, he was already able to complete some advanced number series independently. He dared to say that the students in the second year of high school could only have the same understanding as him, and only those geniuses who could rank first! Ye Ming could see higher than himself in this regard? He didn't believe it! Hmph, I originally wanted to keep a low profile, but you Ye Ming are getting an axe in this class, and I will show my skills to slap you in the face later, making you embarrassed!

was about to give Ye Ming a professional blow, but he didn't expect that his idea had just come to him, and the next moment Xu Xiaoshan was stunned by Ye Ming's words.

"A sequence can be seen as a function that defines the domain as a positive integer set N* or its finite subset n, and it is an important way to understand a sequence of numbers from the point of view of functions, and in general there are four representations of functions, and sequences are no exception, and there are usually four representations... With the deepening of Ye Ming's explanation, the students felt as if they were immersed in a sea of numbers, and they couldn't extricate themselves for a long time.

The usually obscure number series was easily accepted by the students like a cloud of peers under Ye Ming's explanation, and even Cheng Xue couldn't help but be shocked by the gap between herself and him in her heart, listening to Ye Ming talk all the time, she found that she had almost no chance to interject, not because she didn't want to force sarcasm, but she found that she couldn't be sarcastic at all, because in the face of the truth that could not be paradoxed, all brainless sarcasm was just a trick of the clown.

Originally, the rhythm of the whole audience was going to be taken away by Ye Ming in the future, but he didn't expect Ye Ming to suddenly say that there are four ways to represent the number series, which he had never heard of, Cheng Xue suddenly felt that he had found an opportunity, and he was afraid that he would miss it, so he hurriedly interjected: "Impossible! The representation of the number series is obviously three types, the list method, the image method, and the analysis method." Where did the fourth come from, it's just nonsense!"

However, Cheng Xuelai didn't have time to be complacent, but was slapped in the face again.

"So your catties stop here, you don't think you don't have it, it doesn't mean it doesn't exist. Ye Ming smiled coldly, saying that the four methods are enough to be few, you must know that in the Heavenly Dome Continent, there are no less than hundreds or thousands of ways to represent the number series! Even the methods that he has newly researched are as high as six, and the reason why he says four is just that he doesn't want to say it too complicated.

"Classmate Cheng, hear it, this fourth method is called the space method...... Ye Ming immediately said the fourth method he had comprehended on the spot, and every word was like a lightning bolt, slashing at Cheng Xue.

Cheng Xue is also a person who has been evaluated as a gold medal teacher by the whole city, whether it is the truth or the crooked, she can still tell it, what Ye Ming said now, although she has never heard of it, but she can still see that this is a true truth! At least with her current ability, she can't find a paradox to refute it!

Impossible! He's just a high school student! How could a person who even has a mess of grades come up with such a sharp theory! Cheng Xue was terrified, and cold sweat had already covered his forehead, where is this teaching, this is simply a great mathematician publishing his new discoveries in the field of mathematics!

"Which... Can you briefly explain the general formula?" At this time, the first student in the front row of the third group raised his hand and asked, completely forgetting that he had made fun of Ye Ming just now, and had completely regarded himself as a student.

Ye Ming also explained indifferently: "The relationship between the Nth term an of the sequence and the ordinal n of the term can be expressed by a formula an=f(n), which is called the general term formula of this series, although so, the general term formula is still not unique. ＂

"Why?" the student was surprised.

Ye Ming said: "For example, π, its different approximations can form a series of 3, 3.1, 3.14, 3.141 according to the degree of accuracy,... It doesn't have a general formula. ＂

Ye Ming's explanation was indispensable for this classmate, incisive, incisive, incisive, after listening to Ye Ming's class, he felt that the content that Cheng Resentment had spoken for more than 20 minutes just now was like talking nonsense.

Ye Ming's meticulous analysis of the number series made everyone suddenly feel that the haze in front of them had been swept away, and the number series that seemed to them to be extremely difficult like a book in the sky had now become as simple as 1+1.

Lu Xiaoran looked at Ye Ming, and his heart was also full of shock, where is this student lecturing? Where is this teacher lecturing? This is simply an old pedant standing at the top of the field of mathematics preaching and teaching them! Is he really the Ye Ming who had a headache when he saw mathematics before?

The students also expressed their shock, and immediately felt that Cheng Xue's teaching just now was simply naïve and boring, and it couldn't be compared with Ye Ming!

Some students couldn't resist taking notes on the spot. Just kidding, such a fascinating teaching, they were only encountered by the dog Xyun, what does it mean to listen to your words is better than reading a book for ten years? This is a living example, this rare opportunity, how can you miss it!?

Seeing that everyone had entered the state, Ye Ming simply taught some follow-up learning content through his own sorting and analysis.

"Recursive formula: If the relation of the nth term of the sequence {an} to its previous term or terms can be expressed by a formula, then this formula is called the recursive formula of the sequence!"

"Equal Difference Series: If the difference between each term and its previous term from the second term of a series is equal to the same constant, this series is called an equal difference series, and this constant is called the tolerance of the equal difference series, and the tolerance is often denoted by the letter d. ”

Equivalence Medium: ......

"Proportional Series: ......"

Looking at Ye Ming's aura of Ruohanghe, Cheng Xue's face suddenly turned extremely dark, just now I wanted to make fun of Ye Mingyelang's arrogance, but I didn't expect to be slapped hard now, even the genius Xu Xiaoshan, who was considered superior by himself, except for saying a non-nutritious sentence at the beginning, he couldn't find a stalk to pick up in the whole process, and he still looked shocked until now, and now it seems that the rhythm of the entire class has been taken away by Ye Ming alone, who the cares if I, Cheng Xue, is not here？
