The afternoon class is one-dollar calculus, and the class time is from 3:00 to 5:00, so there is still a lot of time.

Chen Hao picked up the textbook and opened it, he had only taken two classes before, and he didn't learn much content, so it was easy to make it up. And in calculus, I also learned some basic things in high school, and I know a lot about calculus. The calculus studied in the first semester of college is just the foundation of calculus, and for Chen Hao, it is a continuation of the content of the textbook in high school.

When he was in high school, in order to improve his math scores, he exchanged his math talent in "Talent Space". Since then, I have worked mathematics, learned the content in the textbook thoroughly, and also made a lot of related Olympiad problems, some of which are calculus. It can be said that Chen Hao's study of calculus has long exceeded the requirements of high school students.

If Chen Hao could get some special training at that time, even if he went to participate in the International Olympiad in mathematics, physics and chemistry, he might be able to win a prize, and he would be able to be sent to Tsinghua University without taking the college entrance examination. It's a pity that Chen Hao rose too late, and when he was successful, he was already approaching the college entrance examination, and his academic performance was not discovered by the school.

In the past, computer science can be said to be a sub-specialty of mathematics, but later the rapid development of computer technology has not only become an independent field, but also promoted the development of mathematics because of the supercomputing power of computers.

Chen Hao originally had a third-class mathematical talent, and he can be said to be a first-class genius in learning mathematics. Later, he obtained a first-class talent in computer science, and mathematics is an important course in computer science, which shows that Chen Hao's learning ability in mathematics will inevitably be improved.

I remember that "The Heavenly Book of Talent Evolution" said that with enough hard work and good luck, first-class talent is enough to make people start a new era, just like Newton discovered gravity.

Chen Hao's thirst for knowledge is strong, and he will inevitably work hard for it. And luck, it's really a matter of luck. Someone once said that the only thing worth pursuing in this world is the truth and the sky above us. Chen Hao was deeply touched by these words, there is truth everywhere in life, some of which have been discovered by us, used to promote social development, and some that have not been discovered or proven, waiting for this capable person to excavate. If you can also make outstanding contributions to the development of this world, it will be in vain.

Unary calculus is also known as unary function calculus, which is the three major components of calculus. Now that he has a foundation, he doesn't look strange now, but because of his talent, Chen Hao looks at books as simple as others reading novels.

Unary function calculus teaches very basic things. The first chapter deals with the three concepts of functions, limits, continuity, and the formula theorem. All three concepts are fundamental concepts in advanced mathematics as a starting point at the university level.

College mathematics, the average college student can think of is that advanced mathematics is difficult. In fact, for outstanding college students, especially those at Tsinghua University who choose to focus on engineering, they learn this advanced mathematics just like learning high school mathematics when they are in junior high school. The beginning of each stage is easy.

In some key high schools, outstanding science students are very interested in science knowledge, and they can learn university courses on their own after completing simple high school mathematics, physics and chemistry early. Many students like them have the opportunity to participate in the World Olympiad for high school students, and China has always been at the top of the world rankings in this regard.

The fact that others can study college courses on their own in high school not only shows that others are excellent, but also shows that a lot of university knowledge is actually relatively basic, but the basic level has been improved and the knowledge coverage is wider.

Who is Chen Hao? He is now a learning genius, a math genius. His comprehension and comprehension of learning is superb.

For this kind of conceptual and theorem dominated subjects. The first thing to do is to grasp the concept and understand it thoroughly before you can study it in depth. To understand a concept, the most important thing is to grasp the two main points of the concept, the first is the basic properties of the concept, what does the concept say? Is it speed, distance, motion, function, graph? The second is the extension of the concept, which research objects are included in this concept? Whether it's for some or all objects. As long as you grasp these two points, the concept can be understood. For conceptual things, rote memorization is the most useless, except for elementary and junior high schools, which can use concepts as fill-in-the-blank questions to produce test papers, universities will not have such simple and shameful questions.

In any subject, comprehension is key, but memorization is also important. Many theorems, formulas, tables, and parameters are important bases for solving problems and research, and these need to be memorized. A combination of comprehension and memorization is a good way to use it.

Whether it is comprehension or memory, it has something to do with people's mental power. How well a person's mental state is is directly related to his learning effect. Otherwise, the teacher advocates reading in the morning and evening, which is very simple to use.

But is Chen Hao's mental strength poor? Chen Hao's spiritual power is definitely bullish, even compared to Ren Tianlong, it is difficult to say that he can beat Chen Hao. After this breakthrough, Chen Hao's entire state has improved a lot, and his mental power is so strong that he can open the first-level space of the "Heavenly Book of Talent Evolution", which shows how strong his spiritual power is.

With the talent for learning, the physical condition, and the fact that Chen Hao is so studious, what reason is there to be stuck in this basic course.

Before class time, Chen Hao had already finished reading the content of the first chapter and the second chapter. Chapter 2 deals with the differentiation of unary functions. The main points are derivatives and differentiations, which are not difficult at all.

However, considering that some people can study for their own undergraduate studies without being admitted to university, with their own strength, this score is very normal. When I was in high school, I reviewed two textbooks a day, and now I have no problem studying one textbook a day. People are improving, talent is also improving, and then knowledge is accumulating rapidly, such a beautiful cycle, it's really not too good.

Chapter 3 deals with the application of derivatives, which is a continuation of Chapter 2.

Chapter 4 is the integrals of unary functions. Differentiation and integration are the two parts of calculus, and differentiation studies instantaneous, such as instantaneous velocity, instantaneous rate of change, which are instantaneous things. Integralism, on the other hand, studies the properties of the whole, such as volume, area, mass, and moment of inertia. To solve practical problems, it is necessary to combine differential calculus with integral calculus. Sort out differential equations in an instant, and then solve them with the help of integrals, going from instantaneous back to whole. Differentiation and integration can be studied separately, but they need to be combined to solve problems, which is why they are always called calculus.

I did the exercises while reading the book, and the exercises after class were quite simple. Chen Hao just looked at the question once, found the key points and the solution method, and turned it over.

"Hey, Chen Hao, why do you look at it so quickly, have you seen everything before?" Ye Rong was packing up his things and preparing to go to class. But when he walked out of Chen Hao, Chen Hao had already turned half of a book.

"Well, I've seen it all, and it's not much worse than high school, it's pretty simple." Chen Hao is telling the truth.

"No, haven't you seen it before? It's all basic, but it's not as fast as you see? Ye Rong was a little puzzled.

"The high school library doesn't have a collection of these books, so you can really check them out." At that time, in order to improve his science level, Chen Hao studied frantically, and also thought about reading university books, but unfortunately the school did not give it a good hand and did not collect it.

"Then after you read the book, will you do the exercises later?" Tong Fei also walked over and asked.

"After looking at it, although it hasn't been solved, there should be no problem."

"It seems that Chen Hao, your title as the champion is not in vain. I can read half of the textbook in two hours, and I can still eat the content thoroughly, which is a bit **. Tong Fei praised a little.

Chen Hao's super high grades, even in Tsinghua University, are what some people choose not to believe. After all, if you surpass others too much, it is natural that some people will have ideas, which is a normal thing. The so-called seeking common ground while reserving differences is now understood as seeking differences without reserving differences. Others have said that they have to come up with a different point of view, whether it is to fight for brilliance or grandstanding, this is a kind of social status quo.

Chen Haiping was not much surprised, this book is indeed very basic, and it is not difficult to learn by himself. Although everyone is a student of Tsinghua University, there are still obvious differences between people. As long as you look at Chen Hao's college entrance examination results, which are much higher than them, you can know that Chen Hao's learning ability is different from theirs.

If they thought that Chen Hao was at most a little more powerful in high school, everyone would stand at the same starting point when they went to college. So now, they have to admit that Chen Hao is indeed a real learning genius.

"Alright, pack up, let's go to class. This is a public course, and there are many people who take the class. If you go to the end, you will have to sit at the back of the classroom. In such a large classroom, some people can even hear what the teacher says vaguely. Chen Haiping reminded.
