Chapter 194

After Bi Qi, several more students raised their hands and asked Teacher Shi for scratch paper.

There is no way, the amount of calculation for the whole test paper is too much.

A piece of scratch paper, completely insufficient.

In this regard, Mr. Shi was not surprised at all.

After asking another teacher to help keep an eye on it for a while, Teacher Shi went back to the office and came back with a stack of scratch paper.

…………

The time for the counting test is from 8 to 10 a.m.

Nine-fifty-ten, Bi Qi's side.

He has completed the first sixteen questions.

However, just because you've answered it doesn't mean you've got it right.

Of these sixteen questions, Biqi was unsure whether he had answered them correctly.

Especially in question 16, Bi Qi didn't even have a good grasp of fifty percent of the right.

But time has not allowed him to do it again.

Biqi's goal is to score more than 95 points in the number of points, so that he will be eligible for the special scholarship.

It is absolutely unsafe to achieve this level alone.

So, for the last additional question, Biqi had to try.

Bi Qi knew that what could be used by Mr. Gu as the finale at the end must be the most difficult question in the whole set of test papers.

But Bizzie still chose to give it a try without hesitation.

Knowing the man and going up is the true character of the hero!

Besides, Bizzie doesn't need to get all the extra tenths.

With half of the score, Bizzy is satisfied.

With this in mind, Bizzy set his eyes on the additional question at the end of the paper.

[Additional question: The constant function f(x)=1 on (0,π) is extended to the period 2π odd and expanded into a sinusoidal function: f(x)~4/π∑(∞,n=1)1/2n-1sin(2n-1)x.

The sum of the first n terms of the Fourier series is denoted as Sn(x), then any x ∈(0,π), Sn(x)=2/π∫(x,0)sin2nt/sintdt, and lim(n→∞)Sn(x)=1.

(1) The maximum point of Sn

(2) Proof lim(n→∞)Sn(π/2n)=2/π∫(π,0)sint/tdt.]

Just looking at the length of the question stem, it is clear that this question will definitely not be easy.

There are two additional questions. ‘

The first question was okay, and after thinking about it for less than a minute, Bi Qi had an idea to solve the problem.

The difficult part is the second question.

For the 10 points of the additional questions, the first question is worth 3 points and the second question is worth 7 points.

It's easy to get the three points in the first question.

But the seven points in the second question, it is difficult to get all of them.

Because at the end of the additional question, there is a note that Gu Lu can write on it.

[Since the solution to the second question is not unique, the scoring standard is that you can get three points for writing one solution, five points for writing two solutions, and seven points for writing three or more solutions!]

Write three solutions to get a full score.

Even Bi Qi, after reading this sentence, his pupils couldn't help shrinking, and at the same time, the corners of his mouth couldn't help but smile bitterly.

It is extremely difficult to come up with a solution to this problem.

Three solutions......

If he was given half an hour, he might be able to do it.

But there are no ifs.

There are less than ten minutes left until the end of the exam.

"Forget it, you can do as much as you can!" Bi Qi shook his head, getting rid of the negative emotions.

Then I picked up the pen and quickly performed the formula on the scratch paper.

…………

Ten o'clock sharp.

The bell rings for the end of the exam.

Teacher Shi stood on the podium, his eyes swept over the panicked people below, sighed softly, and interrupted everyone's action to continue answering the question.

"Students, stop writing, the exam is over. ”

After Teacher Shi's voice fell, the students stopped writing with unwilling expressions on their faces and gave up the last struggle.

"Teacher Fang, wrap up the papers. Teacher Shi nodded to the other invigilator.

Teacher Fang nodded, "Okay." ”

What surprised Teacher Fang was that none of the forty-five candidates in the entire examination room submitted their papers in advance.

This is a rare occurrence!

Could it be that the students in this class have more stable personalities?

Teacher Fang shook his head and quickly dismissed the idea.

A few days ago, Mr. Fang had invigilated the senior substitute exam for this class.

The scene of that day is vivid in Mr. Fang's mind.

Less than an hour after the exam began, two people had completed the early submission of papers.

After that, it was like no one would let anyone, and people kept getting up one after another to hand in the papers.

By the time there were ten minutes left before the end of the exam, there were only five or six students left in the entire exam room.

Teacher Fang originally took today's score test, and the students in this class would copy the scene of the last senior exam, so as early as about forty minutes after the exam began, he wandered near the podium and waited for someone to come up and hand in the papers, with a kind and kind smile on his face.

But he waited left and right, his legs were numb, his face became a little stiff because he had been smiling for a long time, and he still didn't wait for a figure to come up and hand in the papers.

Wait until the end of the exam.

The current Teacher Fang is definitely full of resentment.

…………

"Whew, it's okay. ”

Bi Qi's side, when the bell rang at the end of the exam, he put down the pen and breathed a sigh of relief.

After his last ten minutes of sprinting, he finally got the first question of the additional question and wrote a solution to the second question.

In fact, as for the second solution to the second question of the additional question, Bi Qi almost had a general idea in his mind.

But time did not allow Bizzie to test his idea.

Still, it's a good result.

At the very least, six points in the additional questions can be obtained steadily.

"Classmate, test papers. ”

Teacher Fang said behind Bi Qi, who was still stunned.

"Oh, teacher, give. With that, Bi Qi handed the test paper to Teacher Fang.

However, when they looked at Teacher Fang, they saw a pair of eyes full of resentment.

Seeing Teacher Fang gradually moving away, Bi Qi scratched his head in confusion while packing up his stationery.

He remembered that he didn't seem to offend the invigilator in any way!

Of course, Bi Qi did not offend this Teacher Fang.

Teacher Ke Fang remembered that in the senior generation exam two days ago, Bi Qi was the first student to submit the papers.

This time, Mr. Fang stood on the podium early, and a large part of the reason was to wait for Bi Qi to hand in the paper in advance again.

But...... Not really!

Bi Qi, like the rest of his classmates, waited until the end of the exam.

Of course, this is just a small episode.

After Teacher Shi and Teacher Fang finished collecting the test papers, they packed them in a sealed bag and left.

In the examination room, the students lowered their heads one by one, and their interest was not very high.

This is also normal.

Gu Lu's set of test papers was like a heavy hammer, smashing them on the chest, shattering all their previous pride.

This is because they are not good at learning and cannot rely on others.

That's not a bad thing for them, though.

A genius does not deserve to be called a genius if it can be knocked down by a single setback.

In this count-point exam, they realized that they had many shortcomings, and after making up for them, the final exam of the next semester may be a different picture.

It's not impossible, shame before the snow!

However, when the time comes, Gu Lu will not give them a chance.

…………

PS: Say one thing.

Presumably some book friends already know that the starting point has been asked to rectify again, and this time the situation is more serious, and all the books that are being serialized in the entire "Heterogeneous Super Energy" section are forced to be interrupted for seven days, and the update can only be resumed on the 28th.

Of course, my book belongs to the "Urban Life" section, so it survived.

However, I'm not sure if the scope of the follow-up rectification will be expanded, so I would like to remind you to avoid you calling me a eunuch after this book is broken!

Also, at present, the entire urban classification of books will not display update reminders on the APP after the update, and I don't know when it will be restored.

I update the book every day before 8 p.m., so if you open the book after 8 p.m., you must have updated it, so don't worry.

Well, that's for now.

I'll let you know in the book review section when the worst happens.
