After returning to her dormitory, Xia Mang put down the book in her hand and sat blankly on the edge of the bed.

future?

How far is the future? It’s really not far. After the competition, it will be the high school entrance examination, then the high school entrance examination, and then the college entrance examination.

Time is neither long nor short.

Where does the future lie?

“The sun is slightly cool…”

Xia Mang picked up the phone and found that it was Lu Feng who stopped.

"Hello?"

"get out of class is over, what's wrong?" Although it was just one word, Lu Fengting, who was very sensitive to Xia Mang's affairs, still heard her unhappiness from this word.

Xia Mang adjusted his mood before speaking, "Nothing's wrong."

But Lu Fengting had already heard it, "Your low mood has been revealed from your voice."

"Lu Feng, stop. What do you want to do in the future?"

"What do I want to do in the future? Of course I want to help our little princess make money."

Although this question did not answer his previous question, he already knew why his little princess was unhappy.

"What's wrong? Is our little princess worried about her future?"

"Well, today Teacher Xia said that without a goal in the future, everything is meaningless." His wish now is for her, but what about before? "Lu Feng, what was your wish before you met me?"

Lu Feng stopped and sat at the table, recalling what he originally wanted.

The memory is really distant. It seems like it happened in the previous life before I met Mangmang.

"At that time, I wanted to grow up well, find my father, and ask him why he didn't want me."

Lu Feng's voice was very soft, but Xia Mang still felt a sense of sadness in his words.

Xia Mang originally wanted to open her mouth to comfort him, but before she could, Lu Fengting's tone became relaxed again, "But now this is not my obsession. He doesn't want me, why should I rush to be humiliated by him? I have my little princess now!"

"Yes, you have me now!" Although Xia Mang answered like this, she was recalling the plot of the original novel. Unfortunately, she did not finish reading the original novel, so she didn't know why Lu Fengting later became a villain, nor did she know why he was keen to oppose the male protagonist Fu Jing.

All I know is that Lu Fengting doesn't like the heroine.

Xia Mang's silence made Lu Fengting think she was worrying about the future, so he comforted her, "Mangmang, you don't need to rush around for money in the future. You can find something you like most. Or if you like many things, just do them one by one. The future is still long, and I will always be with you."

After thinking for a moment, he added, "There's no need to worry about choosing a major in the college entrance exam. If you find you don't like what you're studying, you can definitely change your major. I think with your grades, any teacher in any major should be very welcoming."

"All right then!"

"Sometimes there's no need to push yourself too hard. Some people are chosen by their school or major, and you're already good enough to be chosen! What you should do now is go to bed! Embrace the future with energy every day."

"Okay! Good night then!"

"Good night, sweetheart!"

After Lu Feng hung up the phone, he left his seat and stood on the ninety-ninth floor of Radiance, looking down. There was a hustle and bustle of traffic below. Every brick and tile of this city was built with money.

In the future, I will do my best to let you do whatever you want!

Xia Mang was also very well-behaved and went to bed after washing up.

I felt refreshed the next morning!

Ling Zhen was amazed by what he saw.

Without any mental constraints, time passes very quickly.

A month passed in the blink of an eye!

Today, twelve people will decide the real national team and substitutes.

"Today's battle is crucial. I hope all of you can give it your all! We won't say anything extra. We're not in the Department of Diplomacy; we speak with strength!"

After Xia Mang got the test paper, she discovered that the last question was beyond the syllabus?!

But now she has no time to look at these. Every minute and every second of the exam is very precious. She still has to stick to the principle of starting with the easy and then moving on to the difficult, especially during competitions.

After Xia Mang finished all the previous questions and checked them, he turned around to look at the last question.

After reading it, she realized that this was one of the eight theorems that must be memorized in college advanced mathematics: Cauchy's Mean Value Theorem!

This theorem is actually briefly mentioned in high school mathematics, but it is not explicitly stated as a theorem.

Now this question is just to prove this understanding.

This problem is that two functions f(x) and F(x) satisfy the following conditions: they are differentiable in the open interval (a, b), continuous in the closed interval [a, b], and for any x belonging to (a, b), F(x) is not equal to 0. Then there is at least one point G in (a, b) such that the equation [f(b)-f(a)][F(b)-F(b)]=f'(G)F'(G) holds.

“Ding-dong…”

After handing in the test papers, it’s time for everyone to check their answers!

Xia Mang has always maintained the first place, so everyone's first reaction is to come to her for answers.

"Xia Mang, how did you write the last question?"

"Xia Mang, how did you do in the exam?"

If you give Huang Xia a problem to solve, she knows how to do it. But if you give her a theorem and ask her to prove it again without any special numerical values, it will be too difficult for her.

"I did okay on the test! The last question was a little beyond the syllabus, and it comes from the Cauchy Mean Value Theorem in college advanced mathematics. If you're interested, you can go and take a look!" After saying that, Xia Mang didn't stay any longer. She had to go back to pack her things and catch the flight back!

I don’t know how many times Dad and Lu Feng have urged me to stop!

Huang Xia and Ling Zhen followed Xia Mang. Ling Zhen was a little curious, "Xia Mang, how did you know the Cauchy Mean Value Theorem?"

"Interesting! I've read a lot of math literature and it mentioned the Cauchy Mean Value Theorem, but the book didn't give a detailed introduction. Later, I looked it up and found it was in the advanced mathematics class at university, so I collected some problems and tried them myself!"

"You're amazing! I usually just follow what the teacher teaches me. I don't really have any desire to learn ahead of time. As for literature and the like, I don't even bother reading it!"

Xia Mang chuckled, "So, now I'm at a disadvantage!"

"Let's just take the loss! The exam is already over anyway!"

"My suggestion is that you take advantage of these few days off to go back and read more literature, especially those required for university studies. We are high school students, and even if we go beyond the syllabus, we can't go beyond the university level!"

Huang Xia and Ling Zhen both nodded.

"Okay, I'm not going to talk to you anymore. I have to go back and pack my things. I don't know how many calls I've received this month. If I don't go back, my dad will be furious!"
