I Just Want To Be A Salted Fish Quietly
Chapter 3 The Painting Style Is Completely Wrong [Fourth Update! 】
A total of 53 people, almost 70% of the students skipped classes, isn't this a slap in the face of Lao Dai!
There is no way, the students who skip class can only consider themselves unlucky.
Dai Pingbo didn't report to the whole school, he was doing his best.
In fact, Lin Xian could probably guess the thoughts of these students who skipped classes.
It is estimated that they have all inquired about Dai Pingbo, knowing that he has a good personality, and usually does not call names, thinking that it should be fine to skip a few classes once in a while.
However, there are more than one or two people who think so, everyone thinks so, so the current situation has arisen.
To be honest, if it wasn't for Lin Xian's sudden interest in mathematics, he would probably skip class today.
After the roll call, Dai Pingbo glanced at Lin Xian who was sitting in the front row, and his face softened a little.
"Lessons begin now!"
Picking up a piece of chalk, Dai Pingbo began to teach.
"Mathematical modeling is the most common expression of applied mathematics, and it is also the most intuitive manifestation of mathematics in life. Comparing a person to 04 as a whole, then mathematical modeling is equivalent to a human skeleton..."
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 reserve of knowledge.
For example, using mathematical modeling to manufacture a folding chair involves a series of knowledge in materials science, human mechanics, engineering and so on.
In addition, certain computer skills are also required, because mathematical modeling often performs cumbersome and complicated calculations, and using computers can improve efficiency.
Due to the previous atmosphere, the dozen or so girls in the back row began to perform well, and each of them put on a posture of listening carefully, and some were even taking notes.
But listen to listen, the situation is not right.
who I am?
where am I?
what am i doing
After these three soul tortures, these girls finally gave up and played with their mobile phones one after another.
Dai Pingbo ignored them and continued teaching.
On the contrary, Lin Xian was treated like a tutor.
It can be clearly felt that Dai Pingbo was teaching him alone, and when he talked about certain knowledge points, he would stop deliberately and ask Lin Xian if he understood.
If Lin Xian shook his head, he would repeat it several times.
Let a university professor be a tutor, this treatment is too awesome.
Anyway, Lin Xian felt very refreshed.
After the 90-minute lecture, 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. Don't be afraid of mistakes, because only mistakes can make progress.
Dai Pingbo smiled kindly: "I'll give you a homework, you go back and do it slowly, and just leave it to me for the next mathematical modeling class.
As he spoke, Dai Pingbo took out a pen, took out a blank sheet of paper, and quickly wrote down a topic.
After taking the question, Lin Xian looked at it and was a little confused.
[Estimation of deep holes: If you are standing at the entrance of a hole and only have a calculator with a stopwatch function on your body, you would like to estimate the depth of the hole by throwing a stone and listening to the echo out of curiosity, assuming you see a mass m =1kg of stones, and the accurate measurement of the echo time of the court is t=5s, in the following situation, analyze this problem, give the corresponding mathematical model, and estimate the depth of the hole.
(1) Regardless of air resistance;
(2) Affected by air resistance...Proportional coefficient=0.05;
(3) By air resistance,...proportional coefficient=0.0025;
(4) In the above three cases, if we consider the time required for the echo to pass back. 】
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 try."
After Dai Pingbo left, Lin Xian suddenly found that all the girls in the classroom were still looking at him with strange eyes.
Their thinking is similar to that of Lei Hongguang. For a rich and handsome Lin Xian, shouldn't he flirt with girls, drive fast cars, and go to nightclubs?
No matter how bad you are, you can play golf, or bowling.
Lin Xian's performance was too far from their imagination, and they couldn't help feeling a strong sense of disobedience.
The style is totally wrong!
Lin Xian ignored them, packed his books and went back to the dormitory.
Now the day-study procedures have been completed, and I can go out at any time.
Stuffing the alien notebook into his shoulder bag, and taking "Mathematical Analysis" and homework assigned by Dai Pingbo, Lin Xian leisurely drove out of the campus in a Ferrari.
After returning home, after opening the door and entering, Lin Xian couldn't help being slightly taken aback.
The entire house has been refreshed.
There are some art paintings on the walls, and many trinkets on the coffee table and counter. In addition, on the originally empty balcony, there is a wicker chair hanging basket.
Zhuang Tong and Nie Qingqing were lying comfortably in the hanging basket, holding a laptop as if they were watching an online drama.
Seeing Lin Xian came back, Zhuang Tong sat up and smiled, "Honey, are you back?"
"Sure, the house is well furnished!" Lin Xian looked at room 733 and said with satisfaction.
Zhuang Tong's vision and aesthetics are very good, and those decorations fit well with the decoration style of the house.
What satisfied him the most was the wicker chair hanging basket on the balcony, lying on it in winter, reading a book, enjoying the winter afternoon sun, it was simply not too comfortable.
"Like it?"
Zhuang Tong has an expression that is quick to praise me, which is very cute.
"Like it! Reward you well tonight!"
"Ahem! Can you be more careful, there are still outsiders here!" Nie Qingqing said quietly.
This pair of dogs and men became more and more unscrupulous, and it started in front of their own faces.
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 score of 91 and a figure of 87. Although it is slightly worse than Zhuang Tong, it is still a proper goddess. I don’t know how many licking dogs kneel and lick
Both of them have their own advantages and disadvantages. 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 best friends for a lifetime." Zhuang Tong said with a smile.
For a moment, Nie Qingqing's heart was moved.
But thinking that if she became a mistress, her parents would probably beat her to death, so she immediately suppressed this crazy idea. .
