I Just Want To Be A Salted Fish Quietly

Taking Lin Xian's shoulder bag, Zhuang Tong asked intimately like a little wife: "What fruit do you want to eat, I'll peel it for you.

"No, I'll do some problems for a while, you go and play!"

Lin Xian was very satisfied with Zhuang Tong's attitude, and gently pinched her pretty face.

"Well!"

Zhuang Tong let out a soft cry, pecked him on the face, and then returned to the hanging basket, snuggling up with Nie Qingqing to watch online dramas.

The two have similar personalities. If there is no one to accompany her, Zhuang Tong can watch online dramas or do something else at home alone without worrying about her being bored.

This is also one of the reasons why Lin Xian agreed to be her lover.

Many mistresses who are taken care of will become empty and lonely in their hearts after they have no worries about money and lose their goals. In addition, they are mistresses themselves, and it is impossible for the other party to accompany them every day, so many mistresses will go outside to find excitement and mess around behind the back of the money owner.

But Zhuang Tong is different, her character is doomed that she will not feel empty and lonely.

Just like Lin Xian, there are so many interesting things in the world, but life is too short.

Taking out the pen and paper, Lin Xian calmed down and began to think about how to solve this problem.

At first glance, this question may seem overwhelming.

This is typical of mathematical modeling.

It is necessary to use strong logical ability to put forward a hypothesis of a model, and then use mathematical language and words to fill in this hypothesis little by little. Finally, after analysis and calculation, a correct model is obtained.

And the most interesting thing about mathematical modeling is that there is no so-called standard answer.

For example, using mathematical modeling to make a folding chair, different people will make folding chairs with different shapes.

Although the shape is different, as long as it can be used, you cannot say that his mathematical model is wrong.

However, there is no standard answer, but there are good and bad.

Someone designed a folding chair that is more comfortable and easier to carry, which means that his modeling is better.

In the same way, the question posed by Dai Pingbo is also the same.

Looking at the questions on the paper, Lin Xian's brain was running fast, and the mathematics knowledge he had learned before kept flashing by.

After pondering for a while, Lin Xian suddenly had an idea.

The essence of this question is actually to study the law of the speed of falling objects changing with time.

It belongs to the Newtonian mechanics system, and you can try to build a model with partial differential equations.

Once the model is established, the next step is a series of checking and verification.

Thinking of this, the corner of Lin Xian's mouth couldn't help but twitched into a smile, and the pen in his hand quickly wrote down a line of numbers on the paper.

Suppose: T is the echo time, G is the gravitational acceleration...H is the depth of the deep hole.

Solution (1): According to Galileo’s law of falling bodies, we know that……

Before I knew it, an hour passed.

Zhuang Tong glanced at the time, stretched his waist and said: "It's getting late, it's almost time to make dinner!"

"There seems to be no food in the refrigerator." Nie Qingqing said.

"It's okay, I just went to the supermarket to do some shopping."

Zhuang Tong jumped off the hanging basket and said casually, "Honey, what do you want to eat tonight?"

However, Lin Xian didn't answer, and kept his head down, writing vigorously.

"What are you so focused on?"

Nie Qingqing muttered, stepped forward and took a look.

Her eyes were full of dense numbers and symbols, and the calculation formulas line by line made her dizzy.

Who can stand this?

Excuse me, goodbye!

Zhuang Tong couldn't help saying: "I don't understand at all, I'm not cooking!"

At this moment, Lin Xian raised his head and said with a smile, "I don't care, you can do whatever you want.

"Then let's go grocery shopping!" Zhuang Tong said with a smile.

"Go!"

After finishing speaking, Lin Xian lowered his head again.

Once he found the inspiration, the following calculation formula seemed to be a matter of course. This feeling was so refreshing that he couldn't help being addicted to it.

Sitting on the Beetle, Nie Qingqing put on her seat belt and said, "Lin Xian feels so strange!"

"Why is it so strange?" Zhuang Tong asked with a smile.

"It just feels that he is completely different from other rich second generations. I really can't imagine that he actually sat there and did math problems for more than an hour." Nie Qingqing said with emotion

Zhuang Tong held the steering wheel and steered her carefully.

Nie Qingqing felt a little terrified by her look, and couldn't help raising her eyebrows: "What's wrong?"

"Hee hee, I was thinking that we might really be best friends for a lifetime!" Zhuang Tong said with a meaningful smile.

Nie Qingqing pretended to be calm and said, "I... We agreed to be best friends for a lifetime!"

"hehe!"

Zhuang Tong chuckled and didn't expose her.

As a woman, how could she not know that when a woman becomes interested in a man, it means that she is not far away from falling in love with him.

And a man like Lin Xian is like a black hole, it's only normal to attract women.

The two girls went to the supermarket to do some shopping, and when they got home, Lin Xian was still working on the questions with his head down.

Seeing this, Zhuang Tong walked into the kitchen with the ingredients lightly, trying not to disturb him.

seven o'clock in the evening.

Lin Xian raised his head, put down the pen in his hand, and heaved a long sigh of relief.

**~ Done!"

Looking at the densely packed mathematical models on three or four pages of blank paper, Lin Xian felt an unparalleled sense of accomplishment in his heart.

According to the requirements of the topic, he established a total of four models, and after verification and analysis, it was proved that the logic is self-consistent.

In the end, it is only necessary to import all these mathematical models into the computer, and use C++ or MATLAB to obtain the results of the equations.

To be honest, this question is his current limit.

For mathematical modeling, basic mathematics is the key to open the treasure house. The more keys you have, the greater the chance of opening the door to the treasure house. (of)

"We still need to continue studying!" Lin Xian sighed.

At this moment, the system prompt in the brain suddenly sounded.

"Ding~"

"Congratulations to the host for solving the problem and triggering the hidden mission: Champion's Heart!"

【Heart of Champion】

Task requirements: Participate in the Higher Education Society Cup National Undergraduate Mathematical Modeling Contest.

Mission Progress: 0%

Task reward: ??? (The final reward depends on the performance of the host in the competition!)

I go, this also triggers mission zero?

Also, isn't the task too difficult?

Higher Education Society Cup!

In the national college student competition, there are a lot of participating students from 985 and 211 colleges, and there are even strong mathematics departments such as QHBD, FD, and J. It is really too difficult to get a ranking.

Leaving aside, let's just say that the Department of Mathematics of Jinda University next door is full of money. .
