I Just Want to be a Shenhao Quietly

It can be clearly felt that Dai Pingbo is teaching him a lesson alone, and when he talks about certain knowledge points, he will deliberately stop and ask Lin Xian if he understands.

If Lin Xian shook his head, he would repeat it several times.

Let a university professor be the tutor, this treatment is too awesome. Anyway, Lin Xian felt very cool.

After the 90-minute class, Dai Pingbo took a sip of tea and asked with a smile, "How do you feel?"

Lin Xian nodded and said, "It feels like opening the door to a new world, which is very interesting."

"Mathematical modeling is the same as basic mathematics. The best way to improve is to do more questions and not be afraid of being wrong, because you can only improve if you are wrong."

Dai Pingbo smiled kindly and said, "I will assign you a homework, you can go back and do it slowly, and just leave it to me in the next mathematical modeling class."

Saying that, Dai Pingbo took out a pen, took out a blank piece of paper, and quickly wrote a question.

After taking over the question, Lin Xian looked a little stunned.

[Deep hole estimation: If you stand at the entrance of the hole and only have a calculator with a stopwatch function on your body, out of curiosity, you can estimate the depth of the hole by throwing a stone and listening to the echo. The time is t=5, then In the following cases, analyze this problem, give the corresponding mathematical model, and estimate the depth of the hole.

(1) Air resistance is not counted;

(2) subject to air resistance, ... proportional coefficient = 0.05;

(3) subject to air resistance

scalefactor=0.0025;

(4) In the above three cases, if we consider the time required for the echo to return. 】

Seeing his expression, Dai Pingbo patted him on the shoulder and said with a smile, "Go back and think slowly, even if you can't do it, it doesn't matter."

Lin Xian nodded and said, "Okay, I'll go back and give it a try."

After Dai Pingbo left, Lin Xian suddenly found that the girls in the classroom had not left, and all of them were looking at him with strange eyes.

Their thoughts are similar to Lei Hongguang. A rich and handsome person like Lin Xian shouldn't be flirting with girls, racing cars, and visiting nightclubs?

You can play golf, or bowling.

Lin Xian's performance was too far from their imagination, and could not help but feel a strong sense of disobedience.

The style is totally wrong!

Lin Xian ignored them, packed up his books and returned to the dormitory.

Now that the day-study procedures have been completed, you can go out at any time.

Stuffing the alien notebook into the shoulder bag, and taking "Mathematical Analysis" and the homework assigned by Dai Pingbo, Lin Xian leisurely drove his Ferrari out of the campus.

Back home, after pushing the door and entering, Lin Xian couldn't help but be slightly surprised that the whole house was completely new.

There are some art paintings hanging on the walls, and many trinkets are placed on the coffee table and counter. In addition, on the originally empty balcony, there is a hanging basket of rattan chairs.

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 said with a smile, "Dear, are you back?"

"Okay, the house is well furnished!" Lin Xian surveyed the room and said with satisfaction.

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

What satisfied him most was the rattan chair hanging basket on the balcony, lying on it in winter, reading a book, and enjoying the winter afternoon sunshine, it was 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 cough! Can you pay attention, there are still outsiders!" Nie Lili said quietly.

This pair of dogs and men became more and more unscrupulous, and 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 it is slightly worse than Zhuang Tong, she is also a proper goddess.

The two of them each have their own dry seasons, and 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

In an instant, 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 4 Champion's Heart!

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 returned to the hanging basket to snuggle up with Nie Liqing to watch a web drama.

The two have similar personalities. If there is no one to accompany Zhuang Tong, he can watch online dramas for a day or do something else at home alone, and he doesn't have to worry about her being bored.

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

Many children who are fostered will become empty and lonely in their hearts after they have no worries about money and life and lose their goals.

In addition, they are the mistresses themselves, and the other party cannot accompany them every day, so many mistresses will go outside to find stimulation and mess around behind the back of the gold master.

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 put forward a hypothesis of a model, and then use mathematical language and words to fill in this hypothesis little by little.
