Urban Young Fairy

Han Yuan threw the eraser in his hand on the floor.

He put one hand in his pocket, stood there, and looked at Lin Yi’s direction, and he did not care to face Lin.

Originally, his feelings were just gentle.

But the Korean won at this moment, squatting on the body, suddenly has a myriad of sharp points.

The people around you are shocked.

"On the blackboard, I have left something for you, hoping to help you solve this problem."

Han Yuan has a disdainful face.

His blackboard eraser is the most important trunk formula in the answer.

What is left behind is nothing more than the usual things in the details.

But this word was spoken from his mouth, and immediately let the Korean won won the favor of countless people.

At least on the surface, he still let Lin also hand.

"Why, now it’s your turn to solve the problem. Why are you still standing there, not moving?"

When Zhao Shengping saw the Korean won, he looked like an imposing manner, and he could not help but raise his expectations.

Even with his eyes on Lin Yi, there was a lot of disdain.

Can he compare with the Korean won?

School and momentum are not the existence of a hierarchy!

"Erasing the blackboard is a good job, writing such a simple topic, using so many steps, are you still very proud?"

Lin also shook his head slightly, standing in front of the curtain, after a few glances at the subject, he was slowly walking to the blackboard position.

"This is a bit too mad, is this a simple question?"

"I don't know where he is at the root of the digital model. Maybe he hasn't touched the digital model at all? After all, he seems to be a freshman, and the first year of the freshman year is not long. The first book of higher mathematics should not be on. Finish."

Listening to Lin Yi's words, many people below look at Lin Yi's eyes and have a lot of doubts.

The digital model is called a mathematical model.

It is because the concept of the model itself is a three-dimensional image. This is not the same thing as the ordinary mathematics topic, the mathematics that only stays on paper and answers the so-called application questions and proof questions.

It is precisely because of this that the various elements involved and the use of different formula theorems are particularly important.

It is natural to say that the cumbersomeness of solving the problem is not necessary.

Han Yuan answered this question, using only the entire blackboard, and it is simple.

"I would like to see, this student who is so optimistic about Gu Chujie, what is the endurance."

Director Chen also had a very discourse about Lin’s words.

In his eyes, the Korean won's problem solving is not the optimal solution, but it has reached a very high level.

Now, this forest is also completely vetoed in a simple sentence. Isn’t it also saying his strength and vision, some problems?

Zheng Qiuyan has a little worry in his eyes.

She has never seen Lin also answer the digital model.

The mathematics books that she had previously asked Lin to find, apart from the formulas, although there are some digital model training questions, those training questions are too pediatric.

Standing in front of the blackboard.

Lin did not go to the board on the ground, but directly reached out and took a palm to the blackboard.

"What is he doing?"

"Is it hard to be angry and angered, have you given the blackboard?"

When I saw Lin’s move, many people changed their faces.

Zhao Shengping is more subconscious and will rush to block.

Director Chen and others changed suddenly.

Han Yuan is still sneer.

Only the next moment, everyone raised their eyes.

"How could this be?"

"The trough!"

"How did he do that!"

A burst of exclamations sounded one after another.

In the eyes of everyone, I saw that Lin also took a picture of the palm of my hand. I didn’t take the blackboard and shred it. The huge sound in the anticipation did not appear.

On the contrary, with the fall of Lin Yi, on the blackboard, the various numbers and formulas left by the Korean won were completely chalked up and fell off the blackboard.

Less than a few breaths of effort.

The whole blackboard is as clean as new.

It’s like never someone has written and painted on it.

The degree of cleanliness is much cleaner than the erase of the board.

In the air, chalk dust rises.

When everyone has not recovered from Lin’s palm.

But it was seen, Lin, who was standing in the dust, was carrying one hand and then pointing out a finger.

This finger, through the layer of chalk dust, looks like a pretty fairy.

next moment.

Lin Yi’s fingertip position is that it is contaminated with dust that has not yet landed, and it is on the blackboard.

The students at the bottom are all in vain.

Zheng Qiuqi looked surprised.

Director Chen is full of mistakes.

Han Yuan slightly frowned.

And a group of mathematics professors, at this moment, a sudden change in color.

Quiet and terrible in the classroom.

The needle can be heard.

Everyone’s line of sight is fully focused on Lin’s fingertips.

They just saw that Lin also used a finger to draw a square on the blackboard and then hesitated. Then he did not hesitate, and then clicked on it to point out the location of the old well designed in the title.

Further back is the azimuth axis, plus the coordinates of the different points and the location of each optimal solution.

Just one after another.

Lin also has a dull face, and the mathematical model illustrations that come out instantly at the fingertips are not like writing a math problem, but more like painting a picture.

A complete construction design book!

After three minutes.

Lin also pointed to the tip of the light, a dust on the top of the map, all possible points of the location, all in series.

Lin is also close behind, at the last position of the mathematical model illustration, the coordinates of the figure are substituted into it, and the final complete answer formula is obtained.

Lin also gently rubbed the dust between the fingers.

When he was carrying his shoulders and his position, the chalk dust that had risen up and down, and finally the dust settled, all fell on the ground.

The bird is silent.

No one spoke, all looking at the blackboard in front of me.

Above the blackboard, coordinates, illustrations, plus formulas.

Everything is available.

And these things add up, but they occupy only a quarter of the blackboard position.

Not only that, before looking at the Korean Won to solve the problem ~ www.wuxiaspot.com ~ some plausible, full of incomprehensible students, at this moment when seeing this picture behind Lin Yi, all doubts and stunned, all solved.

"The answer... seems to be the same as the answer to the Korean won?"

After a long silence, there was someone, some awkward, and opened his mouth.

The voice, it sounds, seems to be asking, very uncertain.

"How long did he use to answer this question?"

Another student, whispered a question.

"Probably... five minutes?"
