Super Xueba: Start With A Low Control Score!

Method 3?

Cao Tianyuan rubbed his eyes vigorously.

discover……

He really didn't read it wrong, Jiang Nan was actually using the third method to solve the second question of the axis problem.

As for why not method 2?

Because……

Method 2 is over!

While he was whispering to another invigilator, Jiang Nan had already written the second solution.

He fixed his eyes on the second solution.

discover……

This problem-solving idea and process are completely different from the first solution above, but the result can be proved the same.

this……

It is incredible.

"Grass!"

"Grass!"

"Grass!"

"..."

Cao Tianyuan was shocked and couldn't say anything else, except for the grass plant.

f*ck!

It is estimated that other students don't even have a kind of problem-solving idea, even his teacher, who is so confused, he still sees Jiang Nan's problem-solving process, and then he realizes it.

But the result...

Jiang Nan has two ways of solving problems.

Are they all right?

Do not!

wrong!

Not two.

But three.

Jiang Nan is already writing Method 3.

Cao Tianyuan clenched his fists, and quickly focused his attention on Jiang Nan's third method of solving the problem.

I saw...

Jiang Nan flies his pen.

"Swish!"

Just a few breaths.

Method 3 is also finished.

quick!

Incredibly fast.

And its thinking and process are different from Method 1 and Method 2, but the conclusion is the same.

What a real cow.

Better than Red Bull.

Cao Tianyuan only felt his blood boil, rushing straight to the heavenly gate, the rhythm of exploding!

too excited.

Compared to his first marriage and entering the bridal chamber, he was more excited.

It was shocking.

Compared to men's football winning the World Cup, it is more shocking.

Although Jiang Nan's first solution is completely different from the second solution, there is a certain connection.

One is the conventional solution, which is the forward method, and the second is the unconventional solution, which is the reverse method.

One forward and one inverse.

This Cao Tianyuan is still acceptable.

But what the hell is this third solution?

Jiang Nan actually changed a concept directly and used the geometric proof method to solve the function proof problem.

but……

The process is equally clear.

In the end, it is also proved that for any positive number a, x, f(x) is greater than 1, but less than 2.

Eye-opener.

It's really an eye-opener.

Cao Tianyuan only felt a door to a new world in his heart, and he was suddenly pushed open.

Originally, although he was very good in mathematics, he was a senior expert, but in terms of level, he was still far from the professor, and he was stuck in a bottleneck, unable to go further.

otherwise……

He will not stay in high school for decades.

But now...

He suddenly discovered that his bottleneck had been broken, and he could go further along with mathematics.

certainly!

This is not easy to describe in words.

It's pure intuition, or inspiration.

Anyway!

From Jiang Nan's three problem-solving ideas, especially the third one, he has gained too much.

"Enough!"

Sudden.

A strange tone of particle was sent out.

He brought Cao Tianyuan back from the state of impending cerebral hemorrhage...cough cough... epiphany.

It's Jiang Nan.

I only saw him exhale and mutter to himself, "This question is really interesting. It took me a long time."

"It's just that the answer sheet is too small, so I wrote 3 solutions, and there is nowhere to write it. It's a pity."

"..."

"Puff!"

Jiang Nan's words were like a deep-sea torpedo and detonated on the spot.

Behind him, Cao Tianyuan, and another invigilator who had just walked over, all set off turbulent waves in their hearts.

Jiang Nan, Jiang Nan.

Please be a man!

What does it mean to spend a long time?

You have written so far.

It’s just ten minutes after the exam.

That's on the premise that you used two more solutions for the last question, otherwise it doesn't take ten minutes at all.

What does it mean that the answer sheet is too small to write 3 solutions?

Could it be...

Do you have more than 3 solutions to this question?

There is a fourth, fifth?

The invigilator can no longer listen.

He was worried about listening any more.

I had to be so shocked that I had a heart attack, so I didn't dare to pay attention to Jiang Nan anymore, and quietly left to see other students.

As for Cao Tianyuan, the blood pressure that had just been pulled back almost rose again, and it was really a cerebral hemorrhage.

f*ck!

He just felt that he had broken through the bottleneck, he was happy in his heart, and thought about thanking Jiang Nan afterwards.

But now...

just forget it!

This kid is simply not a son of man.

You know, I can't even think of a solution at first.

Even if it just broke through the bottleneck.

I just learned your three solutions.

And you...

There are even more solutions?

It's so cruel.

so horrible.

Even if I make progress, I can't compare to you!

You are electricity.

You are light.

You are the only myth.

I am old and old, I am really old.

Being your math teacher, I really don't know if it is a joy or a sorrow, and I have been shocked.

"teacher!"

"I'm done, can I sleep?"

Jiang Nan had put down his pen and noticed that Cao Tianyuan was behind him, so he couldn't help but turn around to ask.

While questioning.

But his heart was contemptuous.

"really!"

"Old Cao's invigilation is no coincidence."

"But deliberately, deliberately staring at myself."

"but……"

"I didn't release the water, but I did it all right. It must be a perfect score. Just stare at it!"

"..."

"how?"

"Don't you check it?"

Upon hearing this, Cao Tianyuan subconsciously reminded him.

but……

The words have just been exported.

He just wanted to slap himself.

an examination?

Check the fart.

With Jiang Nan's strength and his own vision, he must have done everything right.

"an examination?"

"No need to check."

"How could it be possible to do something wrong with such a simple question? If you have no objection, I will go to sleep."

Jiang Nan grinned at Cao Tianyuan, and regardless of whether the latter agreed or not, he went to sleep at the table.

Ah!

Old Cao, old Cao!

Let you stare at me deliberately, I will give you a face to blame.

Cao Tianyuan: "#￥￥#￥%!!!"

This person.

It's really inappropriate to be a son of man.
