Xueba, I beg you to go and escort him quickly!

And it's the kind of finale question!

That's all for Xu Henghui!

It's just you, Yue Pingting, why are you here to join in the fun?

All teachers, "???"

They were at a loss, and some teachers even frowned, very suspicious.

Are you pretending?

Are you pretending to be thirteen in front of us on purpose?

These two classmates!

Your behavior is a bit like two children who haven't gone to school here discussing how simple Tsinghua and Peking University are!

In the eyes of their teachers, they put Xu Heng aside, they just wanted to say that Yue Pingting was too much!

I don't know what to say...

But as soon as this idea was born, Yue Pingting gave Xu Heng the process of solving the problem.

"Xu Heng, see if I'm doing it right. This question mainly examines the basic knowledge of quadratic functions, inequality proofs, and sequence!"

Nima!

It's breezy!

Also quadratic function? !

Inequality proof? !

Still counting? !

You are only a sophomore in high school!

Sophomore! ! !

Is it a little overwhelmed? !

Have you respected these questions? !

Nima...!

What makes people vomit blood is that you even said "basic knowledge"?

puff-

The teachers really want to educate them in front of them!

But after Yue Pingting gave Xu Heng the process of solving the problem——

next second!

Geek!

The math teachers were all stunned!

Because the idea of the process given by Yue Pingting is completely correct...

There was a senior high school teacher present, staring at Yue Pingting's answer, dumbfounded.

解：因为Qn（a（n-1），a2n），P（n+1）（1/a*a2n，a2n），Q（n+1）（1/a*a2n，(1/a2)*an）

and so……

……

So an=a(a1/a)[(2n-1) power]

difficult!

too difficult!

Just seeing the answer has already dissuaded many people!

Including these teachers, even math teachers!

But, this is just the first question!

There are two more questions below!

It will only be more difficult!

Impossibly simple!

"hiss……!"

All the teachers gasped and looked at Yue Pingting with surprised eyes.

God!

This classmate Yue, what is going on? !

She actually learned beyond the outline? !

And she didn't say that she had learned the super-class, but she even asked Xu Heng to show her, right, this, this... what does this mean?

All the teachers dare not think about it, but probably, they have the answer in their hearts.

Xu Heng, "Well, the first question is correct."

Yue Pingting, "Phew... the first question challenged you to ask this type of question, and I got it right first!"

really! ! !

Xu Heng was the one who set the questions for her! ! !

oh my god!

Did Xu Heng come up with this kind of question at his fingertips?

terror!

horrible! ! !

Terrible! ! !

Looking at the second question.

As Xu Heng continued to nod and continued to say "That's right", some of the teachers were scratching their hair, almost desperate!

You are only sophomores in high school!

You are doing mock questions for the college entrance examination in the third year of high school!

You are actually right!

!!!

Continue to the third question!

Many math teachers have their throats in their hearts!

is true?

Still wrong?

"The third question...?"

Many teachers looked at the math teacher, especially those teachers in the third year of high school.

"Cough cough..."

"Don't look at us like that! We... this... this..."

"All of a sudden, how do we know the answer!"

These math teachers also looked at each other, not knowing what to do.

The other teachers curled their lips, "Several, I didn't ask you to do it! I just looked at it, and no one could know the answer! What we mean is, look at her way of solving the problem! See if it's right..."

These math teachers were obviously guilty.

Even if they looked at the train of thought, they wouldn't be able to know if it was right for a while...

"This question is too difficult, and the thinking is a bit out of the way..."

"If you change it to a graphic one, it will be clear at a glance, so..."

They are making excuses.

But at this moment, Xu Heng nodded his head, "Yes."

"The third question is fine, the idea is OK!"

shit...

Xu Heng, you just read it once, right?

Have you thought about it?

You are right...

I am Nima!This is too fast!

The teachers were dumbfounded, "*%￥##@#￥￥..."

Those math teachers were all ashamed.

One by one you look at me, I look at you... I don't know how to try it...

Yue Pingting was ecstatic, and continued to take out the topic, "What about this one?"

As shown in the figure, in the right triangular prism ABC-A1B1C1, the base is an isosceles right triangle, ∠ACB=90, the side edge AA1=2, D and E are the end points of CC1 and A1B respectively, and the reflection of point E on the plane ABD is Center of gravity G of △ABD

(1) Find the size of the angle formed by A1B and the plane ABD (the result is expressed by the value of the inverse trigonometric function)

(2) Find the distance from point A1 to plane AED

As soon as this question came out, the math teachers were eager to try it.

"I can do this question, let me take a look first..."

"Graphic question, I have no problem!"

"Me too! Me too!"

Behind Xu Heng and Yue Pingting, the teachers whispered...

Because the class itself was noisy because of studying and discussing topics, Xu Heng and Yue Pingting didn't hear the conversation between them at all.

They are eager to try, their eyes are shining.

They even approached Xu Heng and Yue Pingting confidently, getting closer to them.

but--

Yue Pingting, "I always feel that there are different solutions to this problem. Xu Heng, do you have any good ideas?"

puff-

The group of math teachers stepped forward, but immediately shrank back.

Yes, just raised their feet, ready to move forward, but paused in the air for two seconds, then retracted.

"!!!"

Fuck it!

Not checking for errors!

It turned out to be looking for a second way to solve the problem.

puff...
