When the obedient daughter raised her eyes, the bosses went crazy

Chapter 292 Come in and watch Xueba Sheng Bao answer questions online!

Just when Lu Sheng said that the paper on the left was not her paper at all, the whole classroom fell into an uproar.

The girl looked calm, but secretly pushed a written note to Huo Yu who was at the same table.

There was only one sentence written on the note:

[The test paper has been replaced, will the system leave traces? ]

The moment Huo Yu saw the note, his eyes froze.

No one knows Lu Sheng's IQ level better than him, Lu Youming, Han Jing and Lan Yu who are also members of the ka club.

Even if Lu Sheng had the answer to this high school math test, she would not be able to read it.

Originally, Huo Yu didn't know what was going on, but when he heard Lu Sheng say that the test paper had been changed, he immediately realized that someone must have deliberately framed Lu Sheng.

Because if it's just that the answers are similar, then it's not impossible.After all, if the same method is used for the proof questions, the proof process must be quite similar.

But Lu Sheng directly said that it was not his paper at all.

A test paper that entered the admissions office system was replaced. This is probably to the extent that no one would believe it.

Huo Yu saw that Lu Sheng was charged with such a serious crime just now, although his expression didn't show anything, his heart was really aroused.

Want to help, but don't know where to start.

However, Lu Sheng's words reminded him.

It is impossible to perform any operation on any system of the computer without leaving any traces.If Lu Sheng's test paper was really replaced, there must be traces to follow.

So he looked at Lu Sheng, and the two of them looked at each other silently.But there is a certain tacit understanding, so that they have confirmed a certain signal from each other's eyes.

Just as Huo Yu thought, this is indeed to the extent that no one would believe it.

Lu Sheng said that her test paper was changed, and almost no one in the classroom believed it except her friends.

"Someone changed your test paper??" Tang Yiyi, who had been exhausted just now, had found room for improvement, and sneered, "I said, Lu Sheng, do you have persecution paranoia? Or did you see the test paper being released? The matter of you stealing the answer is obviously a certainty, so you deliberately say this in an attempt to confuse the public?"

"That's right, it's a good thing she can say it." Tang Yiyi's good friend Lin Ya chimed in, "What kind of unit is the Admissions Office of Peking University and Qing University? Get full marks on the papers? When the teacher of the admissions office is idle and has nothing to do, is there something wrong with his mind?"

"I declare that this is really the most outrageous statement I have heard this year-my test paper is exactly the same as the standard answer, so I said that my test paper was changed, I really learned."

"Otherwise, what else can she say? The answer is already here, and she can't come up with any other proof."

……

Hearing that other people in the class were talking about it, Lu Sheng looked cold and raised his eyes indifferently: "Who said I can't produce other proofs?"

"The reason why I can tell at a glance that this is not my paper is because my last math problem does not use this solution at all."

Lu Sheng looked at Zhou Wu and asked his opinion, "Mr. Zhou, can I go up and write down my original answer?"

Zhou Wu was also teaching mathematics in Class A.

Zhou Wu was also shocked when he heard Lu Sheng say that it was not her paper that was released, but he has always believed in Lu Sheng's character.

In addition, he needed to verify the matter of stealing the answer, so he didn't refuse Lu Sheng's request, and said directly: "Okay, you can write it up and let me see."

Under the scorching eyes of everyone, Lu Sheng walked to the podium.

The last big question in this special mathematics examination paper is a function question, and the question itself does not have a few words.

A simple function equation is listed. The first question is to prove the monotone interval of f(x) when a=6; the second question is to prove that 1

The first question is not too difficult. Just substitute a=6 into f(x) and find out how much x is equal to. It can be proved.

So most of the people in the class got the score for the first question.

As for the second question, the first half of the proof that f(x)>1 is still relatively difficult, but it is very troublesome to prove and it will take a lot of time.

But the second half proves that f(x)<2, it basically belongs to superclass.

Standing on the podium, Lu Sheng was not at all embarrassed by being accused of stealing and copying the answers. His aura and expression were so calm that he didn't look like a high school student.

She directly pointed to the reference answer on the big screen and said: "Mr. Zhou, you should be very clear that the second half of the second question of this big question is actually beyond the outline."

"For example, in the standard answer given here, f(x)<2 is proved by the scaling property of the inequality."

"But in fact, using the scaling property of the inequality to prove is not the easiest solution. It's just because this method is relatively low-skilled, and it is easier for high school students to understand and master."

"And for senior high school students, it is already very powerful to think of using this method to prove it, so this solution is listed in the reference answer."

"But in fact, I didn't use the scaling property of the inequality during the exam, but the triangular substitution method."

"The triangular exchange method has high requirements for deformation, and if there is a slight negligence, all of them will be proved wrong. But this method can be used to prove that the process can be written in half."

While talking, Lu Sheng picked up the chalk and began to write on the blackboard next to the big screen.

The people in the audience were all contemptuous, wanting to see how Lu Sheng would argue in this situation.

However, when they looked at what Lu Sheng wrote on the blackboard, their eyes changed, showing expressions of surprise and shock.

The body couldn't help but sit upright and became serious, all of them were staring at the blackboard, their eyes followed Lu Sheng's shaking wrist, eager to know what she would write next.

Class A was originally the best students in the third year of Shengjing High School, and they were all very smart.Even if they haven't come into contact with this solution before, they can understand Lu Sheng's proof process.

In the reference answer, the proof process of this small question is filled with a whole paper.

It takes at least half an hour and a minute to prove and think in the examination room, which is why Lu Youming failed to finish the test paper.

But Lu Sheng used this solution, and after writing on the podium for 5 minutes, he stopped chalking and stood aside.

Lu Sheng wrote so fast, as if he didn't need to think about anything at all.

She has finished writing, but the people in the audience haven't finished reading it, or they can't keep up with her train of thought.

When the following people saw the proof process with more than half of the blackboard written, they all reacted one by one, and couldn't help but gasp.

Fuck, it turns out that this question can be solved in this way? ?

Even Zhou Wu, the math teacher beside him, showed a stunned expression.

Lu Sheng looked at him: "So teacher, since I know this method, I can prove that it can save at least 15 minutes in the examination room by using this method."

"Why did I spend half an hour choosing to solve this problem with a solution that is so troublesome?"
