Scholar’s Starry Sea

[What you need to learn]

Write down this line, Bi Wanqing continued: “After all, it’s a Physics competition. You can understand all of them. For example, you don’t need to read the median value theorem. You need to master it. There are these."

Bi Wanqing picked up the chalk and started writing on the blackboard.

[Derivative][Derivative][Definite Integral][Indefinite Integral][Solving Differential Equations][Taylor Expansion]

After finishing Bi Wanqing, I am again in the integral of definite integral. I drew a circle on it, "In terms of integration, what you need to focus on is the various forms of substitution and trigonometric integrals. This can be said to be the most important piece. The most logarithmic integrals you encounter in calculations are You need to change the element into a trigonometric function and then integrate."

Wu Bin listened to a nodded meal below. Fortunately, he conquered the "trigonometric function" a while ago.

"After you have learned solidly, what I want to teach you is the specific application of Calculus in Physics problems. The first point is naturally that you have to formulate differential equations for specific problems. At this point, You have to brush a lot of questions, and I will prepare them for you."

"About how many questions can be shua!?" Hearing Bi Wanqing's words, Wu Bin almost stood up excitedly.

In response to Wu Bin's reaction, Bi Wanqing smiled kindly every time, and then said: "Don't worry, a lot."

"Then very good!"

"In addition, the Taylor expansion is mainly used for small-scale analysis. Sometimes the commonly used First Rank small expansion is not enough, so it is necessary to use Taylor expansion to Second Rank to calculate..."

After that, Bi Wanqing spent almost an hour explaining to Wu Bin the framework and general content he needed to learn.

Seeing Wu Bin's expression of no fear or boredom, Bi Wanqing stepped off the podium and smiled and said to him: "Although most people want to have results in the semi-finals or even the preliminaries, they have to follow I started to do special competition training in the first year of high school."

"But every age has never lacked the master of peerless grace and elegance. I once had a professor who entered high school when he was 8 years old. He was 9 years old. I started to listen to university courses, and then participated in the International Physics Olympiad at the age of 10, 11, and 12, and won bronze, silver and gold medals."

Wu Bin couldn't help but grow up after listening. Mouth, what he now doubts is not only whether the professor also has a system, he even doubts whether the system in his mind is higher than his own.

Looking at Wu Bin's stunned look, Bi Wanqing laughed twice, "If you can pass the semi-finals and enter the national competition, the worst, you can also see the two universities of Beijing University and Jinghua with your own eyes. The scene grabbed the wonderful shots of the National No. 1 players."

"What kind of national competition...what is it like?" Wu Bin couldn't help but think about it.

"National competition~" Bi Wanqing stroked his sparse hair and said with a reminiscence: "The few who performed particularly well in the semi-finals will form a team to fight against other provincial teams. Those who can get to this step, there are only a hundred people all over the country, all of whom are equipped with unique skills. Among them, the students from the two lakes are the strongest. Every year there are people from them who represent the country to participate in IPhO."

'Do you have any tricks against the best in the world...'

Thinking of this, Wu Bin couldn't help but boil with enthusiasm.

Looking at Wu Bin’s combative eyes, Bi Wanqing seemed to recall something and said: "You remind me of a passage my professor said to me before."

"What are you talking about?"

"He said, "competitions. If you like it, you can play, and if you don't like it, you can play something else."

"It seems like... Quite philosophical?"

"In fact, it was his Senior who said casually. Later, he told me the story of his childhood. He liked to dismantle things since he was a child, such as old-fashioned radios, alarm clocks, watches, and game consoles. Dismantle."

"This... isn't this just Brat?"

"But I can put it back after I dismantle it."

"Brat , Boss, teacher, you continue to say."

"Later he told me that electricity is edible, 10v is sweet, 50v is salty, 100v is spicy, and 150v doesn’t feel on the tongue. Now, as for the 220v... you can try it."

Wu Bin, who was listening to the cold sweat, wiped his forehead with his hand, "I think it’s nice to be alive."

>

I can't help feeling: "Shoushou, the high IQ Brat really knows how to play. '

Looking at Wu Bin’s appearance, Bi Wanqing laughed heartily, and patted Wu Bin on the shoulder, saying: "Interest has always been one of the most important parts of learning, and your interest in Physics is even more important to me. I sigh inferiorly, so everything is possible. Come on."

"Why, if you are not interested in Physics, the teacher will work overtime to teach me."

"hahaha, I can see it by you." Bi Wanqing laughed a few times, and then suddenly sighed, "If every student is like you, I guess there will be no more calls for burden reduction."

"teacher, you seem to be particularly concerned about reducing the burden." Wu Bin asked.

"I have experienced the era of gold medals, and look at the present, can I not care about it." Bi Wanqing finished speaking and sighed again.

Speaking of competitions and gold medals, Wu Bin suddenly had a brain hole.

If one day e-sports can promote the development of the world and become the mainstream, everyone will be proud of e-sports, and they will play games every day and train until their livers are bursting, and then parents will start crying.

"Child playing games is too hard. He plays until five or six in the morning every day."

"Isn’t it? Yesterday, I practiced for another eight hours to make up the knife. There was nothing in my eyes. God."

"You are nothing, my child’s waist is hurt!"

Then the Education Bureau couldn’t resist the pressure and began to relieve the child’s burden. Schools are not allowed to enroll students based on the championship of Internet cafes, SOLO competitions, and all kinds of schools are strictly prohibited from setting up key singles classes, key shooters classes, etc. in any name.

Then my country has changed from being able to win consecutive championships to being unable to make it into the qualifiers.

It is estimated that when the time comes, the masses will not just sigh twice like Bi Wanqing, I am afraid that the Education Bureau will dismantle it for you.

After all, it’s just Mathematics, Physics competition is too high-end, only a small number of people can enjoy the fun, most people can’t even read it, but those who like to see can understand it. People, watching the strengths of their own country weaken day by day, can they not be angry?

Looking at Wu Bin, Bi Wanqing said: "And do you think that burden reduction is really as simple as it seems on the surface?"
