Chapter 41 Difficult choices

"This question..."

When Bai Xue reached the third question, his body froze.

He's stuck again!
Question 1: (2) Find limnsin ([-]πen!);

(2) Prove that e is an irrational number
At first glance, Bai Xue thought it was very simple, limit!Looking for a limit?

But look at the symbols in the limit, en...huh?

What is "en!"Bai Xue stepped forward to take a closer look, and couldn't help being dazed.

There was no fluctuation in Bai Xue's mind about en. With his math LV4 strength, he had no idea about this en!Stop looking at it.

"Isn't it? I don't know about college level?" Bai Xue touched his head.

In fact, Bai Xue himself ignored a fact.

Although he is now Mathematics LV4, it does not mean that he has the level of college mathematics. It can only be said that he can do high school mathematics very easily and smoothly. Even the most difficult high school mathematics questions will have ideas, just like the second grade It’s the same as the solid geometry question.But this does not mean that Bai Xue can peek into all the mysteries of college mathematics.

The third question (2) is Dao number theory, which also made Bai Xue frown.

Prove that e is irrational?

e is an irrational number!Is there any need to prove this?Bai Xue felt a little inexplicable.

It's as if 1 is an odd number. Everyone knows it well, but it still needs to be proved?
"Proof by contradiction?"

Bai Xue thought about the concepts of irrational numbers and rational numbers.

Irrational numbers: Infinite non-recurring decimals, cannot be written as the ratio of two integers.

"I assumed that e is a rational number, uh... stuck." Bai Xue found that this assumption was like a stiff dead pigskin, which could no longer be pulled.

He sighed, usually (1) is for (2), he can't even do (1), it's a fantasy to want to do (2).

"None of the two questions..." Bai Xue's face twitched slightly.

I am a math LV4!Just this bird level?
In fact, what he doesn't know is that everyone hasn't even solved the second question yet!

What?You said that some people have already started to do the third question?

I really don't understand the first two questions!
But when everyone skipped the first two questions and answered the third question, their faces recovered a little.

"Fortunately, I will answer one question." Li Junyi almost burst into tears. Fortunately, this third question gave him a glimmer of hope.

"Fortunately, it can be done with Taylor's formula." Wang Wenfeng also looked too excited.

"My God, why did you put the third question in the back and let us waste so long!" Chi Hua's expression was very sad and angry, because he found out that he could do this question too!

From the corner of his eye, he saw that everyone was sitting on the third question, and Bai Xue felt a chill.

This third question... everyone knows it?
Is it just me who is weak?

Bai Xue shivered and raised his head.

Shit, there's only one hour left!

"It doesn't matter, let's try the fourth question first!" Bai Xue didn't dare to hesitate, and continued to look at the fourth question.

Some people may wonder, isn't it enough to do three questions?All three questions are guaranteed to be correct.

Yes, that's right, it is indeed three questions.But these three questions did not mean that they must be the first three questions!

Which question will be solved and which one will be done, won't it be enough to do three questions?

The fourth question is a convex function problem of a function. Bai Xue understood the essence of the question at a glance. Before the brain could fully reflect the idea, the pen had already started to move!
Bai Xue wrote very quickly, and in the blink of an eye, the position of the fourth question was completed!

Bai Xue was stunned. He had not thought that this question only examined the combination of convex functions and calculus. It was so simple that even a provincial champion who did not specialize in competitions could do it with a little time.

Bai Xue scratched his head. He didn't seem to have studied competition specifically?

Do I have the potential to be the provincial champion?
After laughing at himself, Bai Xue took a deep breath, and turned his gaze back to the two questions that had no idea.

"The third question is definitely impossible. Just what this 'en!' is, I don't know, let alone have any ideas."

I don’t even understand the question, and I can’t understand the conditions given in the question. Do you want to have some ideas?

Naturally impossible!
"There are still three 10 minutes left!" Bai Xue's eyes were complicated, and he focused all his eyes on the first question.

"If it's not ordinary logical reasoning, if it's not permutation and combination, and it's not the binomial Yanghui triangle..."

"Could it be statistics?" Bai Xue's eyes lit up, and he quickly picked up his pen and began to write.

"Statistical probability, hypergeometric distribution?" Bai Xue kept listing mathematical formulas on the paper, trying to find a suitable method for this problem among the vast number of methods.

In a blink of an eye, another 10 minutes passed by.

Bai Xue's face finally turned ugly.

"It's useless! None of it! None of it!" Bai Xue roared in his heart. He listed all the methods he had learned in statistics so far, but none of them could correspond to the question.

"I am the captain of the provincial team! Can't even complete the tasks assigned by the coach?"

Compared to having no dinner at night, what Bai Xue couldn't accept even more was that, as the captain of the provincial team, he failed to solve the three questions.

Thinking about his arrogant remarks during the introduction, Bai Xue never imagined at the time that with his math LV4 and hundreds of points of experience, he would not be able to do the training questions for the high school competition.

In his expectation, he would finish the three questions within half an hour, and then leave gracefully.

"It seems that the only way is to turn on the academic master's bracelet..." Bai Xue thought that wearing a transparent bracelet on his wrist could allow the academic master to possess him and solve a question.

However, while Bai Xue had such thoughts, he was also tangled in his heart!

One is that he doesn't know whether the Xueba bracelet is really as awesome as the introduction, and the other is that using the Xueba bracelet is essentially cheating!
The more arrogant the person, the better the grades are, the more they have their own dignity, and the less they allow their grades to be obtained by cheating.Besides, cheating is hated by government teachers and classmates. If a person is not honest, what is the use of getting grades?

Unless he has no choice but to do so, Bai Xue never wants to get the correct answer on a question by cheating. He doesn't want to sell his honesty to God, nor does he want to exchange his dignity.

But now... there seems to be no choice.

If you don't turn on the bracelet, it means you only answered two questions. Not only will you not have dinner, but you will also lose the face of the provincial team captain. This is also your own dignity.

Bai Xue's expression was uncertain, as if two villains were fighting in his heart.

"I've run out this time, so I'll buy a high-level math book when I go back, and study hard!" Bai Xue gritted his teeth and made up his mind.

Thanks to 121 for the reward!Thanks to 54188 for the reward!thank you all! !There will be more updates later! !Also: the reward exceeds 1000 and one update is true!
