"Yes." Tian Lele continued, "You need to show your classmates your learning results, so that they know that you have no problem in absenteeism for more than ten days. ”

Tian Lele was so happy in her heart, she always wanted to find an opportunity to teach Xia Feng a lesson.

This kid is usually too arrogant, and he has been absent from school, but as soon as he came back from the countryside, he began to tease her, as well as Xiao Yun.

That Xiao Yun was so sad during this time, not all of it was due to him.

She was a little unhappy in her heart, why was this kid so arrogant.

It's as if no one can control him.

The equation on the podium is a calculus equation that can only be learned in college, and this equation is not simple, even if you call a college student who is currently in a university class, you may not be able to do it.

To put it bluntly, Xia Feng, this kid will definitely not be able to do it.

As long as Xia Feng can't do it, he will have a reason to discipline him.

Although it is useless to Xia Feng, at least I am happy in my heart.

Tian Lele thought so unscrupulously.

"Come up quickly, don't waste everyone's time." Tian Lele said.

"Hey." Xia Feng sighed and said, "Teacher Tian, why are you doing this, if you have to do this, it will be bad for everyone." ”

When Tian Lele heard this, he was happy in his heart, and felt that Xia Feng seemed to have softened.

And at this time, Xia Feng came out of his seat.

Tang Chen grabbed him on the side and said, "Brother Feng, you really go up, otherwise let's admit it and it's over, there's no need to go up and lose face, right?" ”

Xia Feng turned around and left Tang Chen with a meaningful smile, and said, "Don't worry, the mountain people have their own tricks." ”

This was the second time he had said this, Tang Chen looked confused, he didn't know what kind of mountain man his mountain man was, let alone what his trick was.

No matter how powerful the mountain man is, he is not Einstein, even if he is Einstein, he will not do what he has not learned.

Tang Chen thought so, and many people in the class also cast sympathetic glances at Xia Feng.

At this time, Xia Feng had already gone to the podium, he picked up a piece of chalk and asked Tian Lele: "Teacher Tian, can you just do it directly on the blackboard?" ”

"Hmm." Tian Lele looked at him, and didn't believe that he had done it.

Xia Feng said: "You don't have enough blackboard, just the method in my head."

Solve it, this blackboard may not be enough to write. ”

Hearing this, Tian Lele smiled.

She came up with this equation, how can she solve it and not know?

With the blackboard in such a large position first, how could it not be enough. Tian Lele felt that Xia Feng was talking nonsense, which also proved that he would definitely not be able to solve this equation.

"It's enough for you to write smaller." Tian Lele said with a smile on the side.

"Okay." Xia Feng nodded, picked up the chalk and began to write on the blackboard.

"First find the definition domain, and then the equation, you need to know the simplified formula for this calculus equation."

Xia Feng wrote as he spoke, and soon began to solve the equation.

The moment these words were written, Tian Lele was shocked, her eyes widened, and she couldn't believe Xia Feng's operation at this moment.

Because, judging from the current operation of the summer wind, it is all correct.

All the solution steps were exactly the same as the solution steps in her mind, that is, the algorithm she had just demonstrated on the blackboard.

Obviously, Xia Feng has written down all the steps she took to solve the problem just now.

Okay, you're a summer breeze, you look like you're a fool, but I didn't expect you to listen to what I said.

But being able to remember every step so clearly is a great brain.

The rest of the class also showed expressions of disbelief, which was not the same as the plot they imagined.

This equation is obviously not what they are learning now, even if it is Lin Jiamu, the most powerful student in the class, she can't understand this equation.

But Xia Feng can really solve it?

Could it be that he just wrote down all the solutions of Mr. Tian?

Xia Feng started his hand and quickly solved the equation in his hand, of course, the text at this time occupied a small part of the entire blackboard.

It doesn't matter, although Tian Lele at this time has been frightened by Xia Feng, but then something that surprised her even more happened.

After seeing Xia Feng solve this equation, he immediately wrote three big words in another place on the blackboard: Solution 2.

I'll go!

Tian Lele is collapsed, what is this?

Calling this kid up, I originally planned to make him make a fool of himself, and if he couldn't solve the equation, he could force him to say a few words.

I didn't expect this kid to be on

Not only did I solve the equation, but there were two ways?

Of course, Tian Lele was a top student in college, and she also knew that there were two methods, but she was not very proficient in the other one, because she had to use some mathematically high-level formulas, which were very lengthy.

No way.

Tian Lele prayed in his heart, praying that the summer breeze would not be solved in the second way.

He wanted to make Xia Feng ugly, but he didn't want to make himself ugly.

At first, she thought that Xia Feng had just memorized her solution, so that she could imitate the solution of the equation.

But now it seems that this is not the case at all, which means that he seems to know exactly how to solve it.

Did he learn this?

Something is wrong, where did he go to learn?

This kid makes trouble all day long, and sleeps all day long in class, how can he have the energy to study?

Tian Lele saw it in his eyes, and he felt that Xia Feng was hanging.

Soon, Xia Feng used the second method to solve the equation.

But what made Tian Lele even more puzzled was that this kid hadn't stopped yet, and after the second method was finished, he immediately opened up a new place, and wrote another three big words that shocked Tian Lele in that position: Solution 3.

Almost all the people in the class didn't dare to speak, they kept their voices and just watched Xia Feng's performance.

And Tian Lele's whole person was stiff, like a mummy that had stood for thousands of years.

If the first two methods are still within her comprehension, then the next third solution is beyond her knowledge.

She felt as if Xia Feng was joking again.

The whole classroom could hear pins dropping.

But after the third method is completed, the summer breeze still does not stop, and the fourth method - immediately follows.

Xia Feng didn't speak during the whole process, but he had already made it clear with his actions at this time, who was the boss in the end.

In ten minutes, Xia Feng filled the entire blackboard to the brim.

That's a total of six algorithms.

Including conventional solutions, as well as mapping, guessing, diagramming, and so on.

Seeing that everyone, including Tian Lele, was confused.

And after the six algorithms went out, Xia Feng threw the chalk head aside and said easily: "Teacher Tian, do you see if this is right." ”
