[Linear algebra is actually a big thing, but if we look at the textbook in the hands of the library owner, there are actually three aspects that are more important. 】
[Which three aspects? 】
[Vector, determinant, matrix. 】
【? ? ? ? ? ? ? ? 】
【Book of Heaven. 】
【don't know. 】
[Hahahahahaha I know the words separately, but when they are put together, I just want to ask, what is this? 】
[Let’s talk about the determinant first. In fact, there is a very simple example of the determinant in the textbook. A table with 9 numbers arranged in three rows and three columns can be recorded as a third-order determinant. 】
【Simple. 】
[Redefine the word simple. 】
【Can't understand. 】
[In fact, if you don’t understand, you can memorize the formula. As long as you know that in such a number table, after 9 numbers are arranged in three rows and three columns, as long as you determine the value, you can apply the formula to get the answer. 】
[Moving on, the book actually introduces it in great detail. 】
[A permutation question, how many possible three-digit numbers can be formed from the three numbers 123? 】
[I know this, 6. 】
【123, 132, 213, 231, 312, 321, 6 types. 】
[What about n kinds? Going further, how many possible three-digit numbers can be formed, but now how many rows and columns are possible? 】
[N square numbers, how many possibilities are there to form n rows and n columns? 】
【……】
【……】
【……】
[Museum owner, run! 】
[He actually wanted to really teach me. 】
[Little Sunflower Class has started, but I don’t want to listen...]
[Please, stop talking. 】
[I don’t understand, and I don’t want to understand. 】
[My brain is in knots. 】
[In fact, don’t think so much, just apply the formula in the book. 】
[Brother, stop talking about the topic and just talk about how this is possible with reality. 】
[N square numbers are possible to form n rows and n columns. So if the player is regarded as a number and then invested in different scenarios, how many possibilities are there? 】
【What the hell? 】
[Hey, eh, eh, wait, this seems really okay? 】
[First, the scene. In fact, after the player determines the books, there are only a few books that can create the scene. The scene is actually determined. In other words, is it just a matter of rearranging different scenes in a few books? 】
[Then players enter these scenes one after another? 】
[How many possibilities, a formula? 】
[But it’s still a little different, right? 】
[It feels like there are a lot more unknowns than these questions. 】
[I'm just giving an example. 】
Lu Yu looked at the barrage and made quick calculations in his mind.
What this person said in the barrage may be feasible.
But it's a bit too convoluted, and Lu Yu has no way to get the answer quickly now.
But because of this person, Lu Yu... had some other ideas.
She looked up suddenly.
Then, while everyone was still discussing, they discovered that a group of them had actually passed through the entire campervan and floated in mid-air.
"What the hell?" Lu Youqi was the first to speak out.
Everyone was also confused.
Ana Shen was the first to react. He looked at Lu Yu and said, "Found it?"
Lu Yu smiled reservedly: "I understand a little bit."
"Considering the current world as a three-dimensional space, our position has a specific value. This is also a vector in linear algebra. Once I change this data, our orientation will naturally change due to the change in the data. and cause changes in orientation."
As he said that, Lu Yu made a slight change, and everyone fell on the ground again.
[Fuck. 】
[I think we are different from the owner. 】
[We: Don’t understand. Museum owner: Draw inferences from one example. 】
[Awesome, awesome. 】
[But I feel like this skill is not very useful. 】
[Yeah, I think so too, I thought it would be Wang Zha. 】
[Maybe it’s not fully utilized yet? 】
It just so happened that Lu Yu also mentioned this.
"If I understand this book, I feel that I can pass it directly. However, I feel that the difficulty level is too high, at least for me. It is not only necessary to understand the book thoroughly, but also to extend this point. It is too difficult to integrate with our entire game world. In fact, I can only use some basic principles, and at most, leave here."
"Can you leave here?" Tomorrow was shocked.
The previous Shan Hai Jing they had worked so hard, and this Peppa Pig, although it didn't seem that dangerous, Tomorrow felt that it might not be that simple to leave.
However, how long had they been here before Lu Yu actually said he could leave?
In response, Lu Yu nodded: "Everyone's book should have a chance, it just depends on how we use it. I don't know how to directly clear the copy now, but now this scene..."
Lu Yu told everyone the result directly through actions.
No one knew what Lu Yu did. They only knew that in the blink of an eye, they appeared...
Before chaos.
【Shock! 】
[Ahhhhh, how did you do it? 】
【I'm so confused. 】
【I'm so confused too. 】
[They won’t be able to clear the level in the next second, right? 】
[Hahaha, that’s not possible. Didn’t you listen to the gym owner? She has only mastered the basics now. 】
[I finally understand that the skills in these books are actually very powerful, but how well they can be used depends on the player's brain. If the player is good and uses it to the extreme, this skill can directly pass the level, but if it cannot, just directly Stay in the copy until death. 】
[Of course, it doesn’t matter if you’re not smart. As long as one player figures it out, everyone can figure it out. 】
[Museum owner: Although I have mastered the skills, you don’t have to expect me to use them to their full potential. 】
[It’s not easy for the owner of the museum, hahaha. 】
[But I still want to know how the owner left. 】
Others are also curious about this.
In this regard, Lu Yu explained: "It's still the same principle just now, except that in the world of Peppa Pig, I built a three-dimensional space based on Peppa Pig's world, but when I use this whole chaos as the three-dimensional space At that time, the world of Peppa Pig was just one of them. As long as I moved outside this data, I would naturally leave Peppa Pig."
This means that no matter which scene it is, Lu Yu can let the player teleport out.
However, such teleportation is limited to this chaotic world.
Because Lu Yu could not establish a three-dimensional space based on the real world, she could not determine the location of this copy in the real three-dimensional space.
Therefore, Lu Yu thought, if you want to pass the level, this rule is not required, but no matter how deep it is, at least she has not mastered it yet.
"This is the limit of what I can do at present. I think it depends on you for the details." Lu Yu said.
"What can we do? Shall I roast Chaos?" Lu Youqi blurted out.
And as soon as he said these words——
Several people looked at Lu Youqi.
"It's not impossible." Lu Yu said.
Lu Youqi: "?"
