Chapter 1518 Unusual Problem-Solving Method

Han Yuan dropped the eraser in his hand on the ground.

He put one hand in his pocket, stood there, looked in Lin Yi's direction, and looked at Lin Yi without giving in.

Originally, he felt just gentle and modest.

But at this moment, Han Yuan suddenly had countless sharp edges all over his body.

Seeing the people around, they were all shocked.

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

Han Yuan looked contemptuous.

What he erased with the blackboard eraser were the most important backbone formulas in answering the questions.

What is left is nothing more than some trivial and ordinary things.

But when these words came out of his mouth, Han Yuan immediately won the favor of countless people.

At least on the surface, he still gave Lin Yi a hand.

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

Seeing Han Yuan's menacing appearance, Zhao Shengping couldn't help but feel a little bit of anticipation in his heart.

Even the eyes that led him to look at Lin Yi over there showed a lot of contempt.

Can he compare with Korean won?

school and spirit,

None of them exist on the same level!

"When you wipe the blackboard, wipe it well. You are still proud of writing such a simple topic and taking so many steps?"

Lin Yi shook his head slightly, stood in front of the curtain, glanced at the topic for a while, and then walked slowly to the blackboard over there.

"Isn't it a bit crazy to say this, is this a simple question?"

"I don't think he has any idea of ​​the difficulty of mathematical modeling. Maybe he has never been exposed to mathematical modeling? After all, he seems to be a freshman, and it hasn't been long since his freshman year, so he probably hasn't taken the first book of advanced mathematics." Finish."

Listening to Lin Yi's words, many people below looked at Lin Yi with a lot of suspicion.

The reason why the digital model is called a mathematical model.

It is because the concept of the model itself is a three-dimensional image, which is not the same thing as ordinary mathematics problems, the kind of mathematics that only stay on paper and answer so-called application problems and proof problems.

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

Needless to say, the complexity of solving the problem.

Han Yuan only used the entire blackboard to answer this question, and it was considered simple.

"I want to see what kind of abilities this student who is so optimistic about Gu Chujie has."

Director Chen is also very prejudiced against Lin Yigang's words.

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

Now being completely rejected by this Lin Yijian with a simple sentence, isn't he also talking about his strength and vision, and there are some problems?

There was a little worry in Zheng Qiuchan's eyes.

She has never seen Lin Yi solve such a thing as a digital model.

The math books she found for Lin Yi before explained formulas, although there were also some mathematical and analog training questions, but those training questions seemed too childish.

Stand in front of the blackboard.

Lin Yi didn't pick up the eraser on the ground, but stretched out his hand and slapped the blackboard with his palm.

"What is he going to do?"

"Could it be that you became angry from embarrassment and wanted to smash the blackboard?"

Seeing Lin Yi's actions, many people's expressions changed.

Zhao Shengping subconsciously wanted to rush forward to stop him.

The expressions of Director Chen and the others suddenly changed.

Won still sneered.

But in the next moment, everyone's eyes widened.

"how so?"

"Fuck!"

"How did he do that!"

There were bursts of exclamations, one after another.

In the eyes of everyone, only Lin Yi slapped the blackboard, but did not shatter the blackboard, and the expected loud noise did not appear.

On the contrary, with Lin Yi's palm falling, the various numbers and formulas left by the Korean won on the blackboard were all turned into chalk dust and fell off the blackboard.

It takes less than a few breaths.

The entire blackboard is as clean as new.

It's like no one has ever written or drawn on it.

The cleanliness is much cleaner than that of an eraser.

In the air, chalk dust rose up.

Before everyone recovered from Lin Yi's palm.

But it can be seen that Lin Yi, who was standing in the dust, carried it on his back with one hand, and then stretched out a finger.

This finger, passing through the layers of chalk dust, seems to have the dusty smell of an immortal guiding the way.

next moment.

The position of Lin Yi's fingertips was covered with dust that had not landed on the blackboard.

The students below were all at a loss.

Zheng Qiuchan was surprised.

Director Chen was full of astonishment.

Han Yuan frowned slightly.

And the faces of all the mathematics professors suddenly changed at this moment.

In the classroom, it was eerily quiet.

Needle drop can be heard.

All eyes were focused on Lin Yi's fingertips.

They just saw that Lin also drew a square decisively on the blackboard with one finger, and then without any hesitation, pointed out the location of the old well designed in the title one after another.

After that, the azimuth axis, plus the coordinates of the different points and where each optimal solution exists.

It's done overnight.

Lin Yi's expression was dull, and the illustrated book of mathematical models appeared at his fingertips in an instant. It didn't look like he was writing a math problem, but more like he was drawing a picture.

A complete construction design picture book!

Three minutes later.

Lin Yi swipe across with his fingertips, and a cloud of dust immediately connects the positions of all possible points on the illustrated book together.

Lin Yi followed closely, substituting each coordinate in the figure into the last position of the mathematical model illustration book, and obtained the final complete answer formula.

Lin Yi lightly dusted the dust between his fingers.

When he retracted his hands and carried his back, the chalk dust around his body was finally settled at this moment, and all of them fell on the ground.

There was no sound.

No one spoke, they all stared blankly at the blackboard in front of them.

On the blackboard, coordinates, illustrations, plus formulas.

Everything is available.

And these things add up to only occupy a quarter of the blackboard.

Not only that, the students who watched Han Yuan solve the problem before were somewhat specious and puzzled. Now when they saw the picture behind Lin Yi, all their doubts and bewilderment were solved.

"The answer... seems to be the same as the answer of Han Yuan just now?"

After a long silence, someone finally spoke up, a little nervously.

The voice, it sounded, seemed to be asking, and it was a little uncertain.

"How long did it take him to answer this question?"

Another student asked in a low voice.

"About... five minutes?"
