Super Xueba: Start With A Low Control Score!

Chapter 247 Five solutions, all are five solutions!

Although the solutions of Qin Yumo, Zhang Hao, Su Yu and others are good, they are polar coordinate equations, coordinate systems, cossin, and even drawing, which is very complicated.

this point……

It can be seen from the upper and lower lines of the answer.

If the relevant foundation is not strong, it is really difficult to figure out. For example, people like Huang Sihai are reading the heavenly books.

Even if the foundation is solid, if you don’t carefully consider it, it will be difficult to solve a similar problem next time.

after all……

The slightest loss is a thousand miles away.

I can’t always get the same questions in the exam.

The data is changed.

The vast majority of people in the class are going to be stunned.

so……

That’s not very practical.

Even if their solution is step by step, it is reasonable and well-defined, and it can be regarded as the most orthodox solution.

But Jiang Nan’s several solutions are different.

What are the words to describe it?

That is to make it simple.

Solving problems with the simplest and most basic knowledge naturally becomes faster and faster, and there is no fastest, only faster.

When Jiang Nan wrote the fifth solution.

Five seconds.

He only took five seconds.

This weird and weird “Love Curve Problem” is done.

And even scum like Huang Sihai and Hu Dajun can see clearly and plainly, if you run into a similar problem next time, you will be able to solve it 100%.

Gee!

Although Jiang Nan’s solution was somewhat slanted.

But the practicality is really strong.

It took a long time.

The people barely reacted.

And the next second.

A monstrous hustle and bustle broke out in the classroom.

“Oh oh oh oh oh oh oh oh!”

“Huhuhuhuhuhu!”

“What a dazzling light, what’s the matter? Oh, it turns out that Nanshen teacher is in class…no…showing skills!”

“My leg hurts, my kneecap is numb, what’s the matter? Oh, I was kneeling in class!”

“Someone asked me why I was going to class on my knees, and I pointed to the blackboard to show him, but he knelt just like me!”

“Don’t say anything else, Teacher Nanshen is a real cow!”

“Mama will never have to worry about my studies anymore, don’t ask why, because with the Nanshen teacher, all the problems are paper tigers, a pinch will be broken, soeasy!”

“I would like to call Nanshen teacher the strongest teacher, super teacher, number one in the universe, and invincible in the world!”

“Bullfrog, bullfrog, giant bullfrog!”

“…”

There are five children’s shoes in the class, and they all admire Jiang Nan… ten-body casts on the ground and regards them as gods.

Including Hu Yifei, the head teacher.

Fortunately, she was still worried about Jiang Nan’s teaching before, and she sat in the classroom eagerly to supervise and just in case.

But now it seems.

Sitting up in shock when she was dying, the clown was herself.

With Jiang Nan’s teaching ability.

What can you worry about?

Even if her teaching mistakes caused confusion in class, Jiang Nan’s teaching is unlikely to have any problems.

even……

Innovation in teaching mode, guide students to participate in interaction, and the diversification of topics.

She can’t keep up even if she shoots a horse.

Impressed!

She, the teacher, is completely convinced.

People who are convinced take it orally.

And the other side.

Qin Yumo, Su Yu, Zhang Hao, and Li Qianqian are the same. While knelt down to Jiang Nan, they stared at the blackboard and kept copying.

The goal is self-evident, that is, to learn Jiang Nan’s various problem-solving ideas… as his own.

and……

While copying on one side.

Their eyes are getting brighter and brighter, and they are almost as large as a large light bulb of hundreds of watts.

Just because…

They all have a feeling, that even if the invisible shackles in their minds are broken, the door to a new world in their hearts is about to be pushed open.

Squad leader Qin Yumo was already flushed, his whole body was bloodshot, and his inspiration was about to burst.

On the basis of mathematics, apart from Jiang Nan, she is called second, but no one dares to call first, not even Bai Yingying.

But why can’t she make it up in mathematics?

In this mid-term exam, Bai Yingying was able to get a perfect score, but she only got 130 points?

The reason……

It is that her mathematical thinking is too sluggish and old-fashioned, and she has fallen into a certain misunderstanding, and she can’t spread it out.

This is where she can still get high scores in math tests, but when it comes to Mathematical Olympiad, she instantly collapses.

Not only her.

The same is true for several other students in the class.

certainly!

This cannot be blamed on them.

This is not all their problems, but the educational template from childhood to large has certain restrictions on them.

Because this kind of education template is aimed at everyone, the purpose is to improve the performance level of everyone.

In a big way.

This kind of education is very good, treats everyone equally, does not give up every student, and is very fair.

But from a small perspective, it hinders the personal development of some geniuses and stifles creativity.

Such as Qin Yumo.

Her IQ is absolutely strong.

Otherwise, it is impossible to test the class first time after time.

But her thinking was limited and she couldn’t find a way to break through, so she could only take the first place in the class.

To die is to be the first in the school.

Putting it in the entire Jiangcheng, it’s not enough.

If it is placed on the coast of the provincial capital, it will become a pebble in the sea, and the waves can’t splash a single flower.

Even if she was able to get a score of 680 in the test, and was barely admitted by a prestigious school in Qingbei, her future development would be incomparable with the top four prestigious schools in Binhai Province.

But now…

She vaguely wants to break this shackle.

Her original mathematical thinking is about to change.

That means…

Her upper limit will be greatly increased.

only……

Almost.

Just a little bit of thrust.

What should I do if I can’t catch my inspiration?

Wait online!

urgent!

But in the next second, she was no longer in a hurry, on the contrary, a bright and innocent smile appeared on her pretty face.

Just because…

After Jiang Nan finished the first “Love Curve Problem”, he went on to talk about the second “Broken Arm Vilas Problem”, which is also the five most easy-to-understand, concise and concise solutions.

The first method of solving triangles…

Suppose a person’s height is mcm, and the length from the lower end of the neck to the belly button is ncm, then the leg length is 105cm.

Available……

Solve that m is greater than 169 and 890.

The length from the top of the head to the lower end of the neck is 26cm.

Available……

The solution is n<42,071.

From what is known…

The solution is m<178,218.

In summary.

This person's height m satisfies 169, 890 <m <178, 218, so his height may be 175 cm.

The answer is B.

…

This first solution is a bit more complicated.

But no matter how complicated it is, it is much simpler than the solutions of Qin Yumo, Su Yu and Zhang Hao.

If this is the case, Qin Yumo and others will not be able to grasp the inspiration and break the shackles of thinking.

Emphasis…

Still lies in the following solutions.

The second method of solving geometric series…

The third method of reasoning by analogy…

The fourth solution special value substitution method…

The fifth solution…

…

Do you think this is over?

Do not!

This is just a small test.

Under the stunned gaze of everyone, Jiang Nan successively made the third "Pyramid Question", the fourth "Yenjing Temple of Heaven Question" and the fifth "Piano Music Theory Question".

And there are five solutions.

The first solution is much simpler and easier than the solution of Qin Yumo and others.

And the easier it gets later, and the shorter it takes.

When it comes to the fifth solution, all the knowledge learned by elementary school students is used, and it can be done in five seconds.

what is this?

Can elementary students do high school questions?

The simplest idea is often the best way to solve the problem?

Second Olympics!

This is simply a devil show!
