I Just Want to Be a Salted Fish in Peace

　　Zhuang Tong and Nie Qingqing were lying comfortably in the hanging basket, holding a laptop and seemed to be watching a web drama.

　　Seeing Lin Xian coming back, Zhuang Tong sat up and smiled and said, "Dear, are you back?"

　　"Okay, the house is well furnished!" Lin Xian looked at the 700 rooms and said with satisfaction.

　　Zhuang Tong's vision and aesthetics are very good, and those decorations fit the style of the house very well.

　　What satisfies him most is the rattan chair hanging basket on the balcony, lying on it in winter, reading a book, and enjoying the winter afternoon sunshine, it is not too comfortable.

　　"Like it?"

　　Zhuang Tong's expression of complimenting me is extraordinarily cute.

　　"I like it! I will reward you well in the evening!"

　　"Cough! Can you be careful, there are outsiders!" Nie Qingqing said quietly.

　　This pair of dogs and men became more and more unscrupulous, and they started in front of themselves.

　　Lin Xian put on his slippers and joked, "You can join too, I don't mind."

　　Nie Qingqing's appearance is not low, with a full score of 91 and a figure of 87.Although a little worse than Zhuang Tong, she is also a proper goddess. I don't know how many licking dogs kneel and lick.

　　The two have their own strengths, if she wants, Lin Xian doesn't mind having another lover.

　　"Hee hee, I don't mind, it's better this way, we can be good girlfriends for a lifetime." Zhuang Tong said with a smile.

　　For a moment, Nie Qingqing was moved.

　　But thinking that if she became a junior, her parents would probably beat her to death, so she immediately put down this crazy idea. .

Chapter 106

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

　　"No, I'll do the problem for a while, go and play!"

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

　　"Well!"

　　Zhuang Tong let out a soft moan, pecked him on the face, and then went back to the hanging basket to snuggle up with Nie Qingqing to watch online dramas.

　　The two have similar personalities. If there is no one to accompany him, Zhuang Tong can watch online dramas for a day or do something else at home by himself, and there is no need to worry about her being bored.

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

　　Many of the fostered mistresses will become empty and lonely in their hearts after they have no worries about money and life and lose their goals.In addition, he is a mistress, and the other party cannot accompany him every day, so many mistresses will go outside to find stimulation and mess around behind their backs.

　　But Zhuang Tong is different. Her character is destined to not feel empty and lonely.

　　Just like Lin Xian, there are so many interesting things in the world, and 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 propose a model hypothesis, and then use mathematical language and words to fill in this hypothesis little by little.Finally, after analysis and verification, a set of correct models is obtained.

　　And the most interesting point of 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 works, you can't say that his mathematical model is wrong.

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

　　Someone who designs a folding chair that is more comfortable and easier to carry means better modeling.

　　In the same way, this question from Dai Pingbo is also the same.

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

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

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

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

　　Once the model is established, it is followed by a series of verification and verification.

　　Thinking of this, Lin Xian's mouth couldn't help but evoke a smile, and he quickly wrote lines of numbers on the paper with the pen in his hand.

　　Let: T is the echo time, G is the acceleration of gravity... H is the depth of the deep hole.

　　Solution (1): From Galileo's law of falling bodies, it can be known that...

　　……

　　Before you know it, an hour has 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 vegetables 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 to Lin Xian, "Dear, what do you want to eat at night?"

　　However, Lin Xian did not answer, and kept his head down, writing hard.

　　"What are you doing so focused on?"

　　Nie Qingqing murmured and stepped forward to take a look.

　　Her eyes were full of dense numbers and symbols, row after row of arithmetic formulas, making her dizzy.

　　Who can stand this?

　　Excuse me, farewell!

　　Zhuang Tong couldn't help but said: "I don't understand at all, I'd better cook!"

　　At this time, Lin Xian raised his head and smiled: "I can do whatever you want."

　　"Then let's go grocery shopping!" Zhuang Tong laughed.

　　"Go!"

　　After saying that, Lin Xian lowered his head again.

　　Once he finds inspiration, the next formula seems to be a matter of course. This feeling is so refreshing that he can't help but indulge in it.

　　……

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

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

　　"I just feel that he is completely different from other rich second-generation 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 looked at her carefully.

　　Nie Qingqing was a little hairy when she saw it, she couldn't help raising her eyebrows and said, "What's wrong?"

　　"Hee hee, I'm 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 promised to be best friends for a lifetime!"

　　"Ha ha!"

　　Zhuang Tong laughed 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 from falling in love with him.

　　And a man like Lin Xian is like a black hole, attracting women is a normal thing.

　　The two women went to the supermarket to do some shopping. After returning home, Lin Xian was still doing the questions with his head down.

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

　　Seven o'clock in the evening.

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

　　".~ Get it done!"

　　Looking at the dense mathematical models on three or four pages of white paper, Lin Xian felt an unparalleled sense of achievement in his heart.

　　According to the requirements of the title, he established a total of four models, which were verified and analyzed to prove that the logic was self-consistent.

　　Finally, you only need 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 opening the treasure house. The more keys you have, the greater the chance of opening the door to the treasure house.

(Are you okay Zhao)

　　"I still need to continue learning!" Lin Xian sighed.

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

　　"Ding~"

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