I Just Want To Be a Salted Fish Quietly

Chapter 104

There are a total of 53 people, and almost 70% of the students skipped class. Isn’t it just a slap in the face of Lao Dai?

Dai Pingbo did not report to the whole school, and he had done his best. In fact, these students who skipped class, Lin Xian could probably guess their thoughts.

It is estimated that they have all inquired about Dai Pingbo, knowing that he has a good personality, and generally don’t call names, thinking that it should be fine to skip classes a few times occasionally.

However, there are more than one or two people who think this way. Everyone thinks this way, so the current situation arises.

To be honest, if it were not for Lin Xian’s sudden interest in mathematics, he would probably skip class today.

After finishing the call, Dai Pingbo glanced at Lin Xian, who was sitting in the front row, his face lightened slightly.

“Start class now!”

Picking up a piece of chalk, Dai Pingbo began to teach.

“Mathematical modeling is the most common manifestation of applied mathematics, and it is also the most intuitive manifestation of mathematics in life. Comparing a person to the whole, then mathematical modeling is equivalent to the skeleton of a person…”

Dai Pingbo’s teaching level is still very good. In just a few minutes, he intuitively introduced the specific content and functions of mathematical modeling.

To put it bluntly, mathematical modeling is to transform mathematical knowledge into practical applications in real life.

This requires not only mathematics, but also strong logical thinking ability and a huge knowledge reserve.

For example, the use of mathematical modeling to make a folding chair involves a series of knowledge of materials science, human mechanics, engineering and so on.

In addition, there must be a certain amount of computer technology, because mathematical modeling will often perform tedious and complex calculations, and the use of computers can improve efficiency.

Due to the previous atmosphere, more than a dozen girls in the back row began to behave pretty well, one by one, taking a serious attitude, some of them were even taking notes.

But listening, the situation is not right.

Who am i

where am I?

What am i doing?

After these triple soul tortures, these girls finally gave up and played with mobile phones one after another.

Dai Pingbo ignored them and continued to teach.

On the contrary, it was Lin Xian, who experienced the treatment like a tutor

It can be clearly felt that Dai Pingbo was teaching him by himself. When he talked about certain knowledge points, he would stop and ask Lin Xian if he understood it.

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

Letting a university professor be a tutor is too awesome. Anyway, Lin Xian feels very good.

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, 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 mistakes. Only when you make a mistake, you can make progress.”

Dai Pingbo smiled kindly: “I will assign you an assignment. Go back and do it slowly, and leave it to me in the next class of mathematical modeling.”

With that said, Dai Pingbo took out a pen, took out a piece of white paper, and quickly wrote a question.

After taking the question, Lin Xian looked at him, suddenly a little confused.

[Deep hole estimation: If you are standing at the entrance of the hole and you only have a calculator with stopwatch function on your body, out of curiosity, you can use the method of throwing a stone to listen to the echo to estimate the depth of the hole, and the time is t=5. In the following situation, analyze the problem, give the corresponding mathematical model, and estimate the depth of the hole.

(1) Excluding air resistance;

(2) Subject to air resistance,…proportional coefficient=0.05;

(3) Subject to air resistance

Scale factor = 0.0025;

(4) In the above three cases, if you consider the time required for the echo to come back. 】

Seeing his expression, Dai Pingbo patted him on the shoulder and smiled: “Go back and think about it slowly. It doesn’t matter if you can’t do it.”

Lin Xian nodded and said, “Okay, I’ll go back and try it.”

After Dai Pingbo left, Lin Xian suddenly discovered that none of the girls in the classroom had left. At this moment, everyone was looking at him with weird eyes.

Their thoughts are similar to those of Lei Hongguang, like Lin Xian, who is rich and handsome.

It doesn’t help you to play golf or bowling.

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

The style of painting is completely wrong!

Lin Xian ignored them and packed up his books and went back to the dormitory.

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

Putting the alien notebook into a shoulder bag, and bringing homework assigned by “Mathematical Analysis” and Dai Pingbo, Lin Xian drove the Ferrari out of the campus leisurely.

When he returned home and opened the door to enter, Lin Xian couldn’t help but froze the whole house with a new look.

There are some art paintings hanging on the walls, and many small ornaments on the coffee table and counter. In addition, a hanging basket of rattan chairs stands on the originally empty balcony.

Zhuang Tong and Nie Qingqing were lying comfortably in the hanging basket, holding a laptop as if they were watching a web drama.

Seeing Lin Xian’s return, Zhuang Tong sat up and smiled: “My dear, are you back?”

“Yes, the home furnishings are pretty good!” Lin Xian looked at the room and said with satisfaction.

Zhuang Tong’s vision and aesthetics are very good, and the decoration fits well with the house decoration style.

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

“Like it?”

Zhuang Tong’s expressive expression on me is very cute.

“Like it! Reward you tonight!”

“Ahem! Can you pay attention, there are outsiders!” Nie Lili said quietly.

The dog men and women became more and more unscrupulous, and they started in front of themselves.

Lin Xian put on his slippers and joked: “You can also join, I don’t mind.”

Nie Qingqing’s appearance is not low, with 91 points and 87 points in body.

Although slightly worse than Zhuang Tong, it is also a proper goddess. I don’t know how many licking dogs kneel and lick.

The two have their own dry seasons. If she wants to, Lin Xian doesn’t mind having another lover.

“Hehe, I don’t mind, it’s better this way, we can be good girlfriends for a lifetime.” Zhuang Tong said with a grin.

In an instant, Nie Qingqing’s heart moved.

But thinking that if she became a junior, her parents would probably kill her, so she immediately pressed down the crazy idea.
