Qian Shuai's face was proud, he glanced at Liu Chen, and urged: "Why don't you simplify it yet?"

Liu Chen didn't have to think about it at all, shook his head slightly, and quickly wrote down the answer. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Qian Shuai looked at it again and again, this is indeed the answer, I can't believe it, I can't believe it, I will give the answer directly? I looked at Liu Chen, and then at Sun Shuren on the side, it can't be cheating!

"What about the simplification step in between, not just the answer!" he exclaimed, glaring.

Liu Chen said: "You want to simplify the steps in the middle, right? I'll write it to you, but I'm afraid I can't write it in the space on this blackboard." ”

Qian Shuai sneered: "I'll wipe it for you." ”

He quickly wiped the entire chalkboard clean.

Liu Chen quickly wrote on the blackboard, step by step, with ingenious ideas.

Qian Shuai grew up and his mouth was unbelievable.

Although Sun Shuren knew that Liu Chen would definitely be able to do it, he was completely relieved at this moment, and Zheng Dazhong shouted: "Good boy, good solution." ”

"Liu Chen, that's great. This is Ma Ting's voice, she doesn't care what other people think.

Yang Xue clutched her chest and said, "Wow, this guy is really a little level." ”

But Liu Chen did not stop, and wrote heavily in chalk: "This is a simplification using algebraic methods, and the results are deduced step by step." ”

Then he drew a coordinate system on the blackboard and established a figure, and he got the answer, exclaiming, "This is a solution using analytic geometry." ”

How deep is this understanding of elementary mathematics in high school? Sun Shuren stood aside and looked moved.

Qian Shuai put his finger into his mouth in disbelief and bit it unconsciously.

Liu Chen was really a little angry, he tutored everyone with homework, and there was no return, anyone with a discerning eye could feel the harvest of this class, but Qian Shuai wanted to disrupt the situation.

Human nature is selfish, and they will think about themselves.

Not to mention the grades, I can also prove that I am a cow, Liu Chen is reluctant to show it, after all, a group of high school students and even teachers are too far behind him, and there is no brilliance.

Liu Chen glanced at Qian Shuai, who was stunned, do you think this is the end?

Then he wrote on the blackboard again, and after he finished writing, he exclaimed, "This is a solution that uses trigonometric functions instead." ”

The third way to solve the problem is to solve the problem.

Only then did the students react, and they took out their notebooks and began to record frantically.

Is this the end of it? No.

Liu Chen continued to write about the method of solving the problem.

"This is a solution using polar substitution. ”

The whole classroom was stunned.

Sun Shuren's eyes widened, Zheng Dazhong was thinking about Liu Chen's solution, Xiao Rongsheng was the most calm, and his eyes were also shining.

Liu Chen made a gesture and said, "There is no space on the blackboard, classmate Qian Shuai, please wipe it." ”

And there are four solutions?

Qian Shuai wiped the blackboard indifferently, he had an idea at the moment, and there was no solution?

Students recorded faster, lest they miss it.

"This is the solution of the Fourier transform. ”

"This is the solution to the limit. ”

"This is the law of counter-evidence. ”

"This is a higher derivative of functions. ”

……

Writing a whole blackboard again, Liu Chen looked at Qian Shuai and asked, "Do you still need to solve the problem?"

Qian Shuai shook his head, there was no need, this scene formed a lingering shadow in his heart.

The entire classroom was silent at this moment, and everyone was watching Liu Chen's performance, which shocked everyone's hearts.

Sun Shuren saw it most clearly when he got closer, and he couldn't help but wipe the beads of sweat on his forehead, Liu Chen's realm was even higher than he thought.

Zheng Dazhong shouted: "Good boy, well done, I admire you too much." ”

Not having a daughter of the same age as Liu Chen really made him so regretful, such a likable young man, how good it is to take back his family as a son-in-law, oops, I thought to myself, the old guy actually muttered on his lips.

Xiao Rongsheng heard it clearly, and suddenly thought, "Oh, my daughter is just the right age." "Then I reacted, what am I thinking, how old is Guoping, what is the mess, the key is to look at the college entrance examination.

However, he moved other thoughts, and the more he thought about it, the more he felt that it was necessary, very necessary.

Gu Witch was shouting in her heart, this liar, this big liar, no wonder I am so sure, I am like a fool, and I am worried about him, when is he so high, he is so hidden, there is such a god in the class, I don't know, this head teacher is really in vain.

Meng Qingqing's face was a little red and hot, it was excited, and there was a voice in his heart, I knew that Liu Chen was powerful, I knew it! Sure enough, sure enough, where was I handing him a note last time.

Yang Xue pulled her, like a dream, like a nymphomaniac, and said: "Do you feel that Liu Chen is so handsome just now, my heart is so excited and excited!"

Meng Qingqing said in his heart, I'm so excited.

Du Ning said in a low voice: "Boss, this is the real you, why are you always so low-key." ”

Qian Shuai's skin was already very fair, and it was so red that it was dripping blood at the moment.

Sun Shuren said: "Classmate Qian Shuai, Liu Chen has solved this problem, a total of 8 methods have been used, I have carefully scrutinized each of them, there is no problem, he tutors the students, what do you think?"

"I'm fine. After speaking, he ran out of the classroom directly, it was so embarrassing, he really wanted to find a crack to drill down, it turned out that the level of people was so high, he didn't bother to fight with himself.

The class was over, the teachers left, Principal Sun, Zheng Dazhong, and Xiao Rongsheng also left, and Liu Chen also followed, leaving behind the students who were in the fryer.

"Liu Chen is so powerful, the class is really good, it turns out that people are big bulls. ”

"It's so shocking, when he solved the problem just now, my heart was beating violently. ”

"No, handsome. ”

Yang Xue was still dizzy, like a girl who had suffered from lovesickness, her face was flushed, and she admired the excellent boy standing at the top very much in her heart, and she had blindly worshiped Jiang Yan before.

Meng Qingqing looked down at the book, his heart was sweet, and he couldn't read the content of the book at all.

"Qingqing, you said that Liu Chen would have a high score in this mock test, how do I feel as if I missed something. ”

Meng Qingqing naturally guessed that Liu Chen was probably the real first in the grade, but she was very well-behaved, since Liu Chen didn't say it, she wouldn't talk nonsense, and said with a smile: "I don't know." ”

Yang Xue's curiosity was very heavy, and she stood up abruptly and said, "I...... I went to the supermarket to buy something, so why do I have to restock. ”

After speaking, he hurriedly ran out and went straight to the administrative building, his heart jumped suddenly along the way, and he quietly came to the principal's office like a thief, and eavesdropped on what these people were talking to Liu Chen.
