Chapter 503

………………

What the hell is this?

A series of question marks popped up in Pan Zuan's mind.

[1. Let the complex number z,w satisfy |z|=3,(z+w:)(z:-w)=7+4i, where i is an imaginary unit, z:,w: represent the conjugate complex of z,w respectively, then the modulo of (z+2w:)(z:-2w) is ()

A.√42 B.√.√71D.3………………】

Let's be honest.

Pan Zuan was really confused at the first glance of this question.

This......

Doesn't seem right!

This is the first multiple-choice question.

It stands to reason that the first question of a multiple-choice question should be the easiest question in the whole set of papers!

Therefore, under normal circumstances, the first question of a multiple-choice question is generally a question that examines the knowledge points of the collection, and only a simple calculation is required to get the answer.

And Pan Zuan is now in front of this set of test papers.

The knowledge points examined in the first multiple-choice question are not a collection, after all, it is understandable for the teachers of the proposition group to change the question type a little.

But the crux of the matter is......

The difficulty of this multiple-choice question is a bit too high!

That's not to say that Pan Zuan can't do it.

Rather, the first multiple-choice question should be the question with the lowest difficulty coefficient in the whole set of test papers, but now it is such a difficulty factor.

Doesn't that mean that the later questions will be even more difficult!

Of course......

There is another possibility.

That is, the group of people in the proposition group is playing tricks and moving a question that should have appeared in the penultimate multiple-choice question to the first question, thus causing the intention of bluffing most of the candidates.

Of the two possibilities, Pan Zuan is now more inclined to the latter speculation.

After all, if it is really based on the principle that the difficulty of the later questions will gradually increase on the basis of the first question, then the difficulty coefficient of the whole set of test papers is too high.

According to rumors on the Internet, the difficulty of this year's math paper will only be lower than last year's, not higher than last year's!

Therefore, the reasonable explanation is that the teacher of the proposition group is playing tricks and bluffing them at the beginning.

So, in the initial confusion, Pan Zuan quickly calmed down.

Then, a smug smile appeared on Pan Zuan's face.

"Hehe, teachers of the proposition group, I have seen through the trap you have laid down. ”

"Now, it's my turn to fight back. ”

Pan Zuan held the pen, listed the equations on the paper, and finally worked out the answer to the first question with a lot of effort.

"That's it!"

Pan Zuan had a faint smile on his face and looked at the next question.

[2. Let the function f(x)=sin^4(kx/10)+cos^4(kx/10), where k is a positive integer......]

Pan Zuan: "???"

Things are not quite what he thought!

Why is the difficulty of the second question still so high?

Could it be that the teacher in the proposition group has moved all the most difficult questions after the multiple-choice questions to the front?

It doesn't seem like it's impossible.

Pan Zuan stiffened, and it took a lot of effort to complete the second question, and his eyes fell on the third question.

It's still a multiple-choice question.

Pan Zuan: "......"

Once again, Pan Zuan sensed that something was not right.

It's barely enough to say that two questions with a high difficulty coefficient in a row are in front of you, but three questions in a row are completely unreasonable!

Pan Zuan's heart began to become a little uneasy, and a terrible speculation came to his mind.

Perhaps, my judgment just now was wrong, and the teacher of the proposition group was not playing tricks.

So, Pan Zuan temporarily stopped answering the questions in his hand, and looked back along the test paper one question after another.

In the fourth question, the difficulty coefficient is increased again on the basis of the third question.

In the fifth question, the difficulty coefficient has been increased again.

The sixth question, the difficulty coefficient is promoted to the advanced level, which is an existence that can only be defeated by the top students.

……

Question 10.

[10. Knowing that f(x) is an odd function on R, f(1)=1, and for any x<0, there is f(x/(x-1))=xf(x), then the value of f(1)f(1/100) + f(1/2)f(1/99) + f(1/3)f(1/98) + ...... + f(1/50)f(1/51) is ()]

To be honest, after reading the stem of this question, Pan Zuan felt a deep sense of powerlessness in his mind.

Pan Zuan didn't have any idea of wrestling with the subject.

With such a difficulty factor, I'm afraid it's a pretty tricky one for many top students.

Pan Zuan didn't dare to think about it, and was directly ready to strategically give up this topic.

I have to say that the current Pan Zuan is quite desperate.

Pan Zuan has read all the ten multiple-choice questions.

What made Pan Zuan quite uncomfortable was that the first question, which in his opinion was not low, was really the easiest of the ten multiple-choice questions.

The multiple-choice question, which could be ranked in the last five questions in last year's test paper, is just the first appetizer for the majority of candidates this year.

Teachers in the proposition group, are you kidding me, this year's math paper is so difficult!

Pan Zuan was autistic.

Who said on the Internet that this year's math paper is very simple, this is called simple, this is completely huge and difficult!

In the morning, he also boasted about Haikou, saying that he wanted to get a perfect score in mathematics in this year's college entrance examination.

Now it seems......

Not to mention a perfect score, whether I can pass this time has become a big problem now.

I want to cry!

But Pan Zuan did not forget that it was now in the college entrance examination, even if the difficulty of the test paper brought a big blow to Pan Zuan's mentality, Pan Zuan still quickly adjusted his mood and began to answer the questions step by step.

In the blink of an eye, half an hour has passed since the start of the math exam.

According to the past, Pan Zuan should have finished the topic selection questions early and started to tackle the fill-in-the-blank questions below.

But this time, Pan Zuan has just finished answering the first six multiple-choice questions.

The last three questions of the multiple-choice question have been strategically abandoned by Pan Zuan.

If he was given enough time, he might be able to give it a try, but now that it is the college entrance examination, there are only two hours of time to answer the questions, and Pan Zuan has to race against the clock.

Suddenly, Pan Zuan, who was immersed in answering the question, heard a low whimper.

When I looked up, it was a small girl sitting next to me.

At this time, the small girl was wiping the tears from the corners of her eyes with one hand, covering her mouth with the other, trying not to cry, looking extremely pitiful.

But now is not the time for Pan Zuan to pity others.

Pan Zuan is now completely self-sufficient.

Time is ticking by.

The atmosphere in the examination room was a little depressing, and there was a sobbing sound from time to time, no need to think about it, it was another candidate who was crying by the questions on the math paper.

Even Pan Zuan saw a buddy who just pushed the test paper aside, rested his head on the table, his eyes were empty, and he looked like he had completely given up struggling.
