Super Xueba: Start With A Low Control Score!

Chapter 242 These math problems are very rude!

As expected of the monitor.

It’s not unreasonable that the thirst for knowledge is not strong.

but……

Others are not slow at all.

Immediately after Qin Yumo, people like Su Yu and Zhang Hao also spoke in turn, and even Huang Sihai and Hu Dajun, who were once stingers, spoke enthusiastically.

“Ms. Jiang, I’m a math class representative, but I only passed 128 in the mid-term exam. Can you make me go further? Don’t ask for full marks, as long as there is 140.”

“Mr. Jiang, I don’t know many math problems. May I ask you for help in the future?”

“Mr. Jiang, can you draw some points for us? The kind of college entrance examination required to allow me to quickly improve my grades?”

“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. I am troubled!”

“Teacher Jiang, I have done a lot of questions before, but what 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 Huang Sihai is a scumbag and I hate learning most on weekdays, I actually want to improve my grades, but there is really no way, but this time even Fatty Wang was able to test 538. Then can I improve a little too! I don’t ask for 538, as long as I can get 400 points.”

“And me, Dajun Hu, Nanshen teacher, I can go to a better physical education university with only 400, so I beg my teacher for advice! I can give everything for this…”

“…”

“…”

Everyone said their demands one by one.

Some of them are slightly excessive, and most of them are quite satisfactory. Anyway, it is about improving performance.

To this.

Jiang Nan listened patiently.

Then he laughed.

“Not bad!”

“Although these people have achieved the best results, the enthusiasm for active learning is finally there.”

“It’s not a waste of my hard work.”

“…”

Jiang Nan nodded slightly.

In other words…

What he wants is the enthusiasm of the lower students, who are passionate about mathematics, and are eager to improve their grades.

As the saying goes…

Learning without enthusiasm has no soul. If you don’t even want to improve your grades, you will definitely not be able to improve.

Even if the teacher does his best and works hard overtime to instill knowledge into you, it will be half the result with half the effort, and it will even be counterproductive and cause people’s rejection and resentment.

And Jiang Nan’s “Unconventional Teaching Method for Rapidly Improving Student Achievement” consists of three steps…

The first step: Let students build up the confidence that they are not afraid of a tiger, despise mathematics in their hearts, and no longer be afraid.

Step 2: Turn passivity into initiative, let students ask questions and take the initiative, and even eagerly seek knowledge.

There is a saying how to say…

When a person doesn’t want gold and silver jewelry, it doesn’t matter how you put it on him, he turns around and forgets it.

But when a person wants it very much, even if it’s just a mess of stinky shit, he will treasure it for a lifetime when he gets it.

Just like the above.

Everyone brought it up on their own initiative.

That’s great!

Especially Qin Yumo, the monitor of the squad, said that he wanted to change his mathematics thinking. He had obviously realized his shortcomings.

to be honest……

Qin Yumo is talented and hardworking, but he is too rigid. If he is not good enough, he has read the book to death.

And Su Yu and Zhang Hao are similar people, not only did they die, but they also read too much to grasp the main point.

If it’s not as talented as Jiang Nan, and ordinary people want to take high scores, then focus on the key points, specialize in the content of the test, and fully understand it.

As for the rest, most of the basics are not good, such as Huang Sihai and Hu Dajun, which are typical waste wood.

And to solve these at the same time…

That is the third step of the “Unconventional Teaching Method for Rapidly Improving Student Achievement”…… Do the questions.

But this question is different from the regular one-shot.

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

“All right!”

“I know everyone’s request, and I have agreed.”

“But before that…”

“I will ask a few simple questions first, and everyone will do it carefully. Let me see your specific strength!”

“…”

As Jiang Nan said, he took out a piece of chalk and wrote on the blackboard quickly.

The first question…

One: In mathematics, there are many curves with beautiful shapes and beautiful meanings at noon. 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: The curve c passes exactly 6 whole points (that is, the points where the 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 number of all correct conclusions is…

(A) 1.

(B) 2.

(C) 1 and 2.

(D) 1 and 2 and 3.

[Sp: The picture is very romantic, drawing an apple-like love on the xoy coordinate system].

…

Wow!

As soon as this question came out, the children’s shoes underneath changed in color.

Just because…

This question seems a bit biased!

A horizontal axis plus a love heart, although it looks very romantic at first glance, they have never seen such a picture.

However……

What makes them even more discolored is still behind.

Jiang Nan asked the question to continue.

The second question…

2: In ancient Greece, people believed that the ratio of the length from the top of the head to the belly button to the length of the belly button to the soles of the most beautiful human body was: (√5-1)/2 approximately equal to 0,618, which is called the golden ratio, the famous ” “Broken Arm Venus” is the case.

In addition, the ratio of the length from the top of the head to the throat of the most beautiful human body to the length from the throat to the belly button is also (√5-1)/2, if someone meets the above two golden ratio 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, the height may be…

A: 165cm.

B: 175cm.

C: 185cm.

D: 190cm.

(Sp: Jiang Nan drew a picture of Venus with a broken arm on the blackboard, without clothes…painting…cough cough…).

…

Bottom classmate: “%￥#@#￥%……”

The crowd was stunned.

Let’s not talk about how difficult this question is, it’s really weird to say that this question actually involves Venus!

“who am I?”

“Am I in class?”

“Mama, I’m not dreaming, am I?”

“Do I think these math questions are not serious? The former is love, and the latter is the goddess of Venus?”

“And is this picture too realistic?”

“?????”

“…”

This is the voice of everyone in the class.

This question is actually more weird than the other, completely different from the math questions they have known in the past.

When they saw the next few questions, everyone was completely confused, “Who am I, where am I, where am I going?”

The third question…

3: The Pyramid of Khufu in Egypt is one of the architectural wonders of the ancient world (pictured). Its shape can be regarded as a regular quadrangular pyramid. The area of ​​a square with the height of the quadrangular pyramid as the side length is equal to the area of ​​a side triangle of the quadrangular pyramid.

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

A: (√5-1)/4.

B: (√5-1)/2.

C: (√5+1)/4.

D: (√5+1)/2.

(Sp: Jiang Nan drew a pyramid on the blackboard, gray, black and white, with a certain shadow.).

…

sp: Don’t say me water!

It’s been a long time since I wrote the title, this time it is the inevitable development of the plot.

In order to develop the mathematical thinking of Qin Yumo and other academic masters in the shortest time, but also to consolidate the foundation of ordinary students, it is necessary to find some very special questions, which is not easy at all!

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

and also……

This is just a novel, don’t link to reality!

Don’t spray if you don’t like it, thank you all!
