"Tell me first, what is this?”
Swoosh!
Lu Hang placed the piece of paper in front of Su Zhe. Su Zhe looked up and said without hesitation,"A rational function!"
"Not bad, you're looking at it very seriously, kid!”
Lu Hang grinned. His anger had long disappeared. There was only deep curiosity in his eyes about Su Zhe. It was rare to see a student who self-studied advanced mathematics in high school.
At least in the three classes he taught, not a single student could do it.
In the entire school, there were probably only a few in Class 1, but it was impossible for them to learn the entire book of Advanced Mathematics.
After all, it was quite difficult to learn advanced mathematics on his own without anyone to teach him.
Unless it was a real genius, such as the mathematician Gauss, then it was another matter.
"Listen up, since you know that this is a set of rational functions, then give me the uncertain integral of this set of functions!”
"I don't need you to calculate, just tell me the process!”
"How about it? Will you?"
"I'll give you five minutes to think." Lu Hang handed the paper to Su Zhe.
"No need!"
Su Zhe handed the paper to Lu Hang and looked at him. He held his head high and said word by word,"A rational function is a function that is expressed by the quotient of two predictors. When the degree of the highest term of the numerator is greater than the degree of the highest term of the decimal, it is called a false fraction.”
" When calculating the indefinite integral of a rational function, if the rational function is a false fraction, you should first use the division of a quotient to transform the false fraction into the sum of a quotient and a true fraction, and then find it…"
" If the rational function is a true fraction, we should use..."
" There are two ways to solve an indeterminate integral. The first is to change the element. Suppose…"
" The second is the partial integration method…"
“……”
Su Zhe explained the solution to the problem of solving an uncertain integral with a rational function that Lu Hang had written on a piece of paper without any pause.
Lu Hang was shocked at the beginning, but his mouth was wide open in the end. He could not believe that a student who had always been mediocre in mathematics in class could actually solve an advanced mathematics problem that he had only studied in university.
"Teacher Lu, do you believe me now?”
"Do you want to take another test?"
Indefinite integral of rational functions was actually a basic solution. Just like what Su Zhe said, there were formulas and methods.
It was recorded in the textbooks of advanced mathematics.
Su Zhe knew how to solve problems, so he just needed a set of formulas.
However, he really didn't know how to answer the college entrance examination questions because it involved the adaptation of countless knowledge points. The difficulty was much higher than the basic questions of advanced mathematics.
However, Lu Hang didn't know that!
He didn't know that Su Zhe didn't know any third-year math questions. He thought that this guy had already finished learning advanced math, but this shocked him!
This was equivalent to an expert who had learned the Eighteen Dragon Subduing Palms. In fact, he only knew moves. He did not even have enough proficiency for ordinary palm techniques. However, when he used the Eighteen Dragon Subduing Palms, the enemy would already pee.
Lu Hang was like this now. He would never have thought that Su Zhe didn't know how to do the third-year questions. He would only think that Su Zhe was studying other ideas for the college entrance examination.
Using university methods to solve problems, this…was definitely much simpler than high school knowledge.
The simplest example was the differential function. Some high school complex function questions required countless functions to solve, but using the differential function formula, this question might be countless times easier.
"Su Zhe, when…did you start learning by yourself?”
Lu Hang had completely believed that Su Zhe had learned Advanced Mathematics. Even if he wasn't proficient in it, he clearly understood many formulas and theories.
That was enough.
After all, high school questions only required advanced math formulas and some theories.
"A few months ago!"
Su Zhe said casually, but Lu Hang nodded."Yes, you're so thoughtful. No wonder your math test results weren't very good during that period of time. You were probably distracted by studying advanced math, right?”
“……”
Su Zhe scratched his head in embarrassment. In fact, he was really embarrassed.
His math results were bad because he didn't know how to do it.
Teacher, you're really thinking too much.
"Alright, I won't talk to you about the questions today. Tomorrow, we'll discuss it together!”
Lu Hang said and was ready to leave. After all, he had been delayed for almost half an hour. He still had classes to attend later.
Upon hearing that Lu Hang was leaving, Su Zhe quickly stood up to welcome him."Teacher Lu, take care!"
"Yes, I will report this matter to your form teacher, Teacher Wang!”
"Hey, kid, tell me, how could you hurt your hand like this? Otherwise, I really want to see how much you can score in the mock exam?”
"I heard from Teacher Wang that it's very likely that you won't even be able to take the college entrance examination?”
Lu Hang looked at Su Zhe's right hand with pity. Su Zhe's face suddenly became sad."Yes, so I'm thinking about studying the university textbooks now. Just looking at the questions isn't the solution…After all, looking at the questions isn't as impressive as doing them myself!”
"Yes, you're right. Alright, since you've thought it through so clearly, I won't stop you!”
"This might be a solution, as long as you can learn it!”
"Of course, don't put the cart before the horse. You still have to memorize the basics of high school mathematics!”
"After all, this is the main point!"
Lu Hang earnestly explained some matters to Su Zhe before he took the documents and turned to leave the dormitory.
Seeing Lu Hang walk out of the door, Su Zhe let out a long sigh.
"Damn it, it wasn't easy…I've passed the math test!”
"The next difficulties are physics, chemistry, and biology!”
Su Zhe shrugged slightly. He felt that it was not easy for him to take the college entrance examination after his rebirth even if he had the answer!
Fortunately, he didn't have much pressure in English and Chinese.
As for physics, chemistry, and biology, they weren't as difficult as mathematics.
The steps required to solve the questions weren't as high as mathematics. The main requirement was knowledge points. Su Zhe was confident that he could fool the teacher.
After all, he had Lu Hang's help.
Su Zhe was almost certain that the first thing Lu Hang would do when he got back was to brag about his self-study in front of all the teachers in the office. That way…the school would not be too suspicious if he was able to surpass the gods in the college entrance examination.
As for the Department of Education, it would depend on the school's response.
Su Zhe believed that Sucheng High School No. 3 would not give up this opportunity to promote themselves and the school.
Which school wouldn't want a genius student who " self-studied university teaching materials " to appear?
The school would definitely do their best to promote Su Zhe!
"Su Zhe, you're really a fucking genius!”
"To think that you could think of such a brilliant plan!”
Su Zhe grinned, looking a little narcissistic. However, he calmed down in the next second.
After all, it wasn't time to let down his guard. Su Zhe looked at the university textbook beside him again.
"We can't celebrate yet. Let's not be careless!”
"If the Education Bureau comes back, I have to have a plan!”
Su Zhe immediately looked at the book he learned in university-Quantum Mechanics!
