Everyone's eyes looked at Liu Sen.

I'm grass, boy, and you want to roast me on the fire, and I'll tell you how naïve you are.

Liu Sen glanced at it and said, "You don't know such a simple question, don't you?"

As soon as these words came out, Han Ru was very calm, Zhu Qingqing and Yuan Bin did not have mood fluctuations, and neither did the quiet girl Zhang Xiaowen, only Xia Yin and Zhang Yiming provided 100 points together, Liu Sen wondered, this can't stimulate the emotions of the school bully?

Seeing that I was about to lose money, I had a grass, and sure enough, the mentality of the top student was very good.

Yuan Bin looked at it coldly, I see what you can say.

Liu Sen walked up to the podium slowly, unhappy, very unhappy, and said: "This problem can indeed be solved with "Elementary Mathematics", our high school knowledge is absolutely enough, the process is cumbersome, Zhu Qingqing's answer is correct." ”

Zhu Qingqing's expression softened a little.

Yuan Bin angrily reprimanded: "Obviously there is a more concise method, do you still have to bother your brains to die? My problem-solving process has no flaws, I am good, you two must be wrong!"

Han Ru was watching the play on the side.

Liu Yun frowned, a little unhappy.

"Why can't you wait for me to finish speaking?" Liu Sen was also angry, what are you shouting, "Zhu Qingqing's answer is correct, but there are logical loopholes in the process, your assumptions here are not comprehensive, and there is a situation where f(x) is 0. ”

As he spoke, he added the steps for solving the Elementary Mathematics method.

Zhu Qingqing's eyes lit up and said, "I thought about it." ”

I couldn't help but blush on my white and tender face.

"Impossible! My method is flawless, my result is no problem, what's wrong?" Yuan Bin suddenly became excited again.

Han Ru's face changed, he also saw Zhu Qingqing's logical loopholes, but he didn't expect to be pointed out by Liu Sen, and he felt a sense of powerlessness.

Yuan Bin took a closer look and was suddenly stunned.

Liu Sen's method is more advanced than what Zhu Qingqing wrote, and it also uses high school knowledge, but the angle is more ingenious, the reason why he does not recognize Zhu Qingqing's result is that she brought a little assumption, and now, he frowned, and said in his heart, am I wrong?

I hadn't thought that he was wrong before, but I quickly knew what the problem was.

This question cannot be simplified directly by using Lobida's rule, and it does not meet the conditions, first use the sin function to be equivalent to infinitesimal and the numerator and denominator to offset a factor.

His face turned a little red, and he looked extremely angry.

Zhu Qingqing breathed a sigh of relief, her eyebrows were full of joy, but she was still cold, she still had an impression of Liu Sen, knowing that it was Liu Yun's younger brother, she had heard that her grades were average before, and her eyes were a little obscene, but she didn't expect that she was suddenly so strong in mathematics, she actually secretly observed Liu Sen a few times.

Liu Yun didn't understand this question and couldn't tell it.

The other students also watched and did not speak.

Yuan Bin snorted coldly and turned around and left, not saying anything.

Liu Sen said: "Yuan Bin, don't be in a hurry to leave, you haven't finished talking yet." ”

"What do you want?"

There are still seven solutions that have not been shown, are you running a fart? That's not spending 200 spiritual power in vain.

Zhu Qingqing also said: "Yuan Bin, why don't you listen to Liu Sen's speech?"

Yuan Bin was very ashamed and angry in his heart, but he couldn't go any further, and said angrily: "Haven't you finished speaking?

"Just now this is the solution of "Elementary Mathematics", and the solution of "Advanced Mathematics", you use one method, but the application conditions are wrong, you should transform it about an x, and then use Lopida's rule......"

Yuan Bin's face turned red, he couldn't wait to get into the cracks in the ground, and turned his head to leave.

"Wait. ”

"What else?"

"There is a second solution to "Advanced Mathematics", you see, you can use the integral method......

After hearing this, Yuan Bin's face was flushed with shame, his breathing was short, and he was about to rush out again.

"Wait. ”

"You...... What else do you want? I was wrong. "Yuan Bin is about to go berserk.

"Actually, there is a third solution, you listen to me tell you slowly, don't worry, Taylor series expansion can also be, approximate the denominator below, find the series limit, and it's very simple, just change it......"

Yuan Bin felt a great sense of powerlessness, and his expression on his face was uncertain.

Liu Sen shared seven solutions in "Advanced Mathematics", Yuan Bin gasped, looked at Liu Sen in a daze, and spit out a sentence after a while, "You are very strong." ”

He felt a sense of frustration, and for a moment his faith was shattered.

Han Ru also had a great sense of sourness and frustration in his heart, he originally thought of Zhu Qingqing's loophole, and also wanted to hit a Liu Sen, but he didn't expect the gap to be so big.

Zhu Qingqing's beautiful eyes flashed.

Liu Sen had a toothache on his face, Yuan Bin didn't provide any emotional energy, Han Ru provided a wave of 100 points of jealousy, and Zhu Qingqing, who looked cold on the surface, actually produced a wave of 120 points of envy energy, Liu Yun also had 30 points of envy, and the others added up to 100 points.

A girl with a cold appearance, but her inner emotions are so rich, much stronger than Jiang Xue.

Finally, there is no loss.

Liu Sen pondered, if I strangle the grass, did I use too much force all of a sudden, and hit these school tyrants, and the feelings of envy, jealousy and hatred are not strong.

Liu Yun, Zhu Qingqing, and Liu Sen walked together.

It's rare to see this on campus.

Zhu Qingqing wanted to say thank you to Liu Sen, but when it came to his mouth, he couldn't say anything, Liu Sen didn't say anything, and walked quietly beside him, Liu Yun crusaded against Yuan Bin.

"Everyone is a junior high school classmate, and after knowing each other for so many years, Yuan Bin is becoming more and more proud. ”

Zhu Qingqing said: "He liked mathematics in junior high school, and it became even more intense in high school. ”

"What if it doesn't work? It's too risky. ”

"He's always been that character. Zhu Qingqing said coldly, "In mathematics, he is empty-eyed, and he is afraid that he will be sad tonight." ”

When he arrived at the carport, Zhu Qingqing left first.

Liu Yun laughed and said, "Brother, do you like Zhu Qingqing?"

It made Liu Sen inexplicable, he likes wool, he is cold like that, and his body is too flat, he is not porridge, he is more cheesy, and he still feels that Jiang Xue's trembling is more emotional.

"It's the first time I've seen you so manly, yes, yes, chasing girls is to be brave. Liu Yun encouraged, and continued: "Zhu Qingqing has been very smart since elementary school, and she said that if she wants to find a boyfriend in the future, she will find someone smarter than her." ”

Liu Yun also went back to the classroom to get a physics exercise, she couldn't spend too much time on the math competition.

Liu Sen thought seriously, since he had already participated in the league, it would be impossible to quit, even if the provincial league was solved with spiritual power, there would be selections within the team, entering the national team, and several selections, the spiritual power consumed would also be huge, and it would not be able to improve the self-confidence coefficient.

At this stage, the most effective way to increase soul power is the self-confidence factor.

Discussion within the team, answering questions among classmates, you can't always use spiritual power, and you can't afford to consume it.

There is only one way to go, to raise mathematics to level II, which is almost the level of a perfect score in advanced mathematics, and there is no problem in participating in the IMO.

When I came to the bottom of the teaching building and took a look, Liu Sen was immediately furious, I strangled the grass.
