Mr. President, I will not make an appointment

Chapter 568 Looks like a different person
For several days in a row, Si Ji's mood was inexplicably good, full of energy, unprecedentedly high, and he didn't even sleep in class.

The students were all stunned, looking out the window again and again, wondering if the sun was coming out from the west.

The teachers also found it very strange, and some even wondered if they had made a mistake. After all, Si Ji had never been interested in class. When I came to the classroom, I also asked to be transferred from the last row to the first row. When I was in class, I stared at the blackboard, staring bigger than Niu Ling.

"Si Ji, come and answer this question." The teacher in charge asked a difficult question, deliberately testing it.

Si Ji stood up unhurriedly, and replied, "It is always zero, and the power is lowered. For the reciprocal, that is, when e is the base, it is directly counted down, and when a is the base, it is multiplied by 1/lna, which means the same, but especially Yes, the exponential function of natural logarithm is completely unchanged, and the general exponential function must be multiplied by lna, the positive variable becomes redundant, the covariant becomes positive, and the cutting square, that is, the cutting function is the square of the corresponding cutting function (reciprocal of the cutting function), and the cutting multiplication Cut, reverse fraction."

"..." The class teacher's jaw almost dropped.

That's exactly what he's going to summarize next!
And this kid is actually better than what he summed up, more comprehensive and more concise!
"Cough...that's a good answer, please sit down." The teacher in charge pushed his glasses awkwardly.

The students also looked at each other in blank dismay. The question Si Ji answered just now refreshed everyone's understanding of him.

God knows how difficult the course of calculus is. Most of the students work hard every day and still suffer unspeakably, but one of them skips class every now and then, even in class, he sleeps soundly. How could he be proficient in the calculation rules of derivatives?

"So handsome! So handsome!" The girls were all elated. Originally, Si Ji was very popular, but now he became the male god in the hearts of the girls.

The boys all had dull eyes, obviously stunned.

Si Ji remained as usual, sat down silently after answering, and continued to listen carefully.

The male classmate at the same table poked his arm secretly, and asked in a low voice, "Hey, did you take the wrong medicine today?"

Si Ji didn't even bat an eyelid, "You just took the wrong medicine, can't I be a good student one day?"

"That's not true, but it's really strange that you are like this, you don't look like you anymore, it's like a different person!" The male classmate at the same table, Monk Zhang Er, said puzzledly.

Si Ji just smiled slightly, and continued to look ahead with an extremely serious expression.

When the class was about to end, the head teacher announced another thing. The Mathematical Olympiad competition will be held in two months, and now the number of applicants will be counted.

Si Ji raised his hand for the first time, causing everyone to be dumbfounded.

You must know that he never participated in this kind of thing before, not only did he not participate, but he also disdained it.

Sign up today!

It doesn't look like he's joking at all!

Is he hanging up?
Some people even wondered if it was really Si Ji who was sitting in the classroom today. Could it be that he and his twin brother had switched identities?
However, although Si Ji and Si Qi are twin brothers, they probably belong to the kind of fraternal twins, although they resemble each other, they are completely different.

We have been classmates for so long, and everyone can tell the difference between the two at a glance.

So is the sun really coming out from the west?

Still, what stimulated him?
