Super Scholar: Start with a low regulatory score!

Chapter 242 These math problems are very unscrupulous!

Worthy of being the squad leader.

It's hard to say that this thirst for knowledge is not strong.

but……

Others are not slow at all.

After Qin Yumo, people like Su Yu and Zhang Hao also spoke in turn, and even Huang Sihai and Hu Dajun, who had been stabbing heads, also spoke enthusiastically.

"Mr. Jiang, I'm the representative of the mathematics class, but I only got 128 in this midterm exam. Is there any way you can make me go further? I don't need a perfect score, as long as I get 140."

"Mr. Jiang, there are many math problems that I don't know. Can I ask you for advice in the future?"

"Mr. Jiang, can you draw some key points for us? The kind that is compulsory for the college entrance examination, so that I can improve my grades quickly?"

"Mr. Jiang, how can I remember this math formula quickly and well! I always forget and forget, but when it comes to the exam, I can't remember it, so distressed!"

"Mr. Jiang, I have done many problems before, but what should I do if I still can't do it now?"

"Mr. Jiang, how should I learn this function! Especially the trigonometric function, I always make mistakes..."

"Nan Shen... Teacher, although I, Huang Sihai, am a scumbag and hate studying on weekdays, in fact, I really want to improve my grades, but there is really no way, but this time even Fatty Wang can take the 538 exam. Then can I improve a bit too! I don’t ask for 538, as long as I can get 400 points.”

"And I, Hu Dajun, Teacher Nanshen, I can go to a better physical education university with only 400 yuan. I beg the teacher for advice! I will give everything for this..."

"..."

"..."

Everyone expressed their demands one by one.

Some of them are a little too much, and most of them are quite satisfactory, anyway, to improve grades or something.

In this regard.

Jiang Nan listened patiently.

Then he laughed.

"Not bad!"

"Although these people are one of the hottest horses, the enthusiasm for active learning is finally there."

"It didn't take my hard work in vain."

"..."

Jiang Nan nodded slightly.

Speaking of...

What he wanted was the kind of low-level students who were passionate about mathematics and eager to improve their grades.

As the saying goes...

Learning without enthusiasm is soulless, and if you don't even want to improve your grades, you will definitely not be able to improve.

Even if the teacher tries his best and works overtime to instill knowledge in you, it will be half the result with twice the effort, and it may even have a counterproductive effect, causing people to repel and resent.

And Jiangnan's "Unconventional Rapid Improvement of Student Performance Teaching Method" is divided into three steps...

The first step: Let students establish the self-confidence that newborn calves are not afraid of tigers, despise mathematics in their hearts, and no longer be afraid.

The second step: turn passive into active, let students ask questions and take the initiative, and even eager to seek knowledge.

There is a saying how to say...

When a person doesn't want gold, silver and jewelry, no matter how much you stuff them, it's useless. He turns around and forgets.

But when a person wants it very much, even if it's just a pile of stinky shit, he will cherish it for a lifetime after he gets it.

Just like the above.

Everyone volunteered.

That's great!
Especially the monitor, Qin Yumo, said that he wanted to change his mathematical thinking, obviously he had realized his own shortcomings.

to be honest……

Qin Yumo is talented and hardworking enough, but he is too dull, to say the least, he has read the book to death.

And people like Su Yu and Zhang Hao are similar. Not only have they read the book to death, but they also read too complicated to grasp the key points.

If it is not as talented as Jiang Nan, ordinary people want to get high scores in the exam, then focus on the key points, specialize in the content of the exam, and understand it thoroughly.

As for the rest, most of them have no foundation, such as Huang Sihai and Hu Dajun, they are typical useless firewood.

And to solve these at the same time...

That is the third step of the "Unconventional Teaching Method for Rapidly Improving Student Performance"...to do the questions.

But this question is different from the regular random one.

While ensuring the quantity, we must also ensure the quality, and more importantly, the speed and method, and these are not ordinary problems.

"All right!"

"I understand everyone's request and agree to it."

"But before that..."

"I'll start with a few simple questions, and everyone should work hard, and let me see your actual strength!"

"..."

While talking, Jiangnan took out the chalk and started writing quickly on the blackboard.

The first question...

One: In mathematics, there are many curves with beautiful shapes and beautiful meanings. Curve c: x^2+y^2=1+|x|y is one of them (as shown in the figure), and the following three conclusions are given...

1: Curve c passes through exactly 6 integral points (that is, points whose horizontal and vertical coordinates are integers).

2: The distance from any point on the curve c to the origin does not exceed √2.

3: The area of ​​the "heart-shaped" area enclosed by the curve c is less than 3.

Among them, the serial numbers of all correct conclusions are...

(A) 1.

(B) 2.

(C) 1 and 2.

(D) 1 and 2 and 3.

[sp: This picture is very romantic, drawing a heart like an apple on the xoy coordinate system].

……

Whoa!
As soon as this question came out, the children's shoes underneath changed color.

just because...

This question seems to be a bit biased!

A horizontally increasing coordinate plus a heart, although it looks very romantic at first glance, but they have never seen such a picture.

however……

What made them even more discolored was yet to come.

Jiangnan continued to make questions.

The second question...

Two: In the ancient Greek period, people believed that the ratio of the length from the top of the head to the navel to the length from the navel to the bottom of the foot of the most beautiful human body was: (√5-1)/2 is approximately equal to 0, which is called the golden ratio. The famous " "Broken Arm Venus" is like this.

In addition, the ratio of the length from the top of the head to the throat to the length from the throat to the navel of the most beautiful human body is also (√5-1)/2, if a person satisfies the above two golden ratios.

And the leg length is 105cm, and the length from the top of the head to the lower end of the neck is 26cm, then its height may be...

A: 165cm.

B: 175cm.

C: 185cm.

D: 190cm.

(sp: Jiangnan drew a picture of Venus with a broken arm on the blackboard, without clothes... painted... ahem...).

……

The students below: "%￥#@#￥%..."

Everyone was stunned.

Leaving aside how difficult this question is, let me just say that it involves Venus, which is really weird!
"who am I?"

"Am I in class?"

"Mama, am I dreaming?"

"Am I the only one who thinks these math problems are not serious? The former is love, and the latter is the goddess Venus?"

"And isn't this picture too realistic?"

"?????"

"..."

This is the voice of everyone in the class.

In fact, each of these questions was more bizarre than the next, and it was completely different from the math questions they had known in the past.

And when they saw the next few questions, everyone was completely confused, "Who am I, where am I, and where am I going?"

The third question...

Three: The Pyramid of Khufu in Egypt is one of the architectural wonders of the ancient world (as shown in the picture). Its shape can be regarded as a regular pyramid, and the area of ​​the square whose side length is the height of the pyramid is equal to the area of ​​a triangle on the side of the pyramid.

Then the ratio of the height on the base of the side triangle to the side length of the base square is...

A: (√5-1)/4.

B: (√5-1)/2.

C: (√5+1)/4.

D: (√5+1)/2.

(sp: Jiangnan drew a pyramid on the blackboard, gray and black, with certain shadows.).

……

sp: Don't say I'm watery!
It's been a long time since I wrote a title, this time is the inevitable development of the plot.

In order to develop the mathematical thinking of Qin Yumo and other top scholars in the shortest possible time, and to consolidate the foundation of ordinary students, we must find some very special questions, which is not easy at all!

These few questions are all really weird college entrance examination questions in recent years (you can go to Baidu).

and also……

This is just fiction, don't hook it up with reality!
If you don't like it, don't spray it, thank you!
