They Gather Here

"It's really rare that a high school points question can reach this level of difficulty."

"First convert rectangular coordinates to polar coordinates."

"Can it work?"

"I don't know, but isn't mathematics just something that comes out of experiments?"

……

Lots of people, lots of talk, lots of ideas.

Luo Zhen moved his gaze to Nakano Wuyue.

Unexpectedly, not only did the girl not have the idea of ​​testifying, but the hair on her head changed from [_(|3」∠)_] to [ヾ(?°?°?)??], obviously to cheer her up Son.

This is no way.

Fortunately, it didn't take long to solve a math problem. Luo Zhen simply stepped onto the podium and carefully examined the problem.

Soon, the idea came, and he picked up the pen.

Really dare to do it?

But all teachers hate students who pretend to understand. The female teacher originally only wanted Luo Zhen to go back to her seat to listen to the class, but now she was really angry.

She frowned slightly: "Can you do this question?"

Luo Zhen is not a fool, he naturally felt the change in the other party's mood.

"There is an idea, but after writing the calculation, we can determine whether there are any loopholes." His answer left room.

"Then let's start." The female teacher erased the questions on the blackboard, "Write down the ideas for solving the questions."

"Hey?"

"Hurry up."

Luo Zhen blinked in a daze, and then he couldn't laugh or cry.

Anyone can tell that the other party doesn't believe in him, and deliberately set up a card test.

He simply didn't say anything more, just picked up the chalk, and wrote the topic silently on the upper part of the blackboard.

Nakano Wuyue had written down the topic long ago, and after comparing it, it was sure that it was word for word.

The teacher is awesome!

The girl cheered in her heart while clenching her fists.

In fact, writing out an integral formula silently is nothing——

When solving math problems, both students and teachers mostly adopt linear thinking. As long as they have thought deeply, they will naturally recall the original problem.

Therefore, the female teacher was not surprised——

The focus is on problem-solving ideas.

After Luo Zhen silenced the topic, he didn't think for a long time, but wrote down smoothly.

In the current era of the Internet and informatization, blackboard writing seems to be being replaced by advanced teaching tools such as PPT and video.

There is a word called "characters are like people", so when the female teacher saw Luo Zhen's beautiful chalk characters, her brows unknowingly relaxed.

People who write beautifully are not necessarily noble in character, but those who write with correct strokes are mostly rigorous.

To everyone's surprise, Luo Zhen didn't even fill a blackboard.

In just a few dozen lines, he completed the last step, and the steps seemed very clear.

Everyone was in a dazed state, thinking that at least they were preparing to take the exams for various famous domestic schools, and they had already entered the review stage. Why did they suddenly become scumbags?

The female teacher folded her arms with great interest, facing the blackboard, and muttered something.

"Did you omit some steps?" she asked.

"I've written all the scoring points." Luo Zhen put down the chalk in his hand.

"???"

"I'm really too lazy to write so much. Anyway, answering the question like this will definitely get full marks."

This kid is too crazy.

The female teacher was somewhat angry, but she had no choice but to divert her attention and stare at the problem-solving steps on the blackboard.

After about ten seconds, she looked back at the students who were "waiting to be fed" and said, "Don't use the same thinking to solve this problem."

The classroom immediately became noisy.

The female teacher pressed her hands down, and waited until everyone was quiet before continuing, "There are two points in this integral problem. First, convert rectangular coordinates to polar coordinates..."

Hearing this, Nakano Wuyue was slightly taken aback.

She felt deja vu, and after thinking for a long time, she realized that Luo Zhen seemed to have taught herself the same problem-solving thinking.

To be honest, it's not that the girl hasn't tried it just now, but she still can't do anything.

It can be seen from this that imitation is imitation after all, and only after a lot of brushing questions can one be as easy as Luo Zhen.

If learning is likened to practice, then Nakano Wuyue has undoubtedly not mastered it yet.

The girl was a little discouraged, and the female teacher said again: "Second, using interval symmetry, this part can be simplified through calculation and become cot (cotangent, the reciprocal of tangent·tan)."

It dawned on me.

Those students are all here to review, so naturally they can understand it.

Although the knowledge points involved in Luo Zhen's solution are not too difficult, the thinking is novel.

The teacher is not allowed to use the same idea, the reason is that this solution is too "smart", and it is difficult for students who are not particularly good to think of it in a moment.

As a matter of fact, most people should adopt a relatively safe strategy when taking the exam, with only one purpose——

Resolutely not lose the points that should be obtained, and strive for the points that are difficult to obtain.

However, Luo Zhen didn't plan to take the university entrance exam, so he coughed lightly and changed the topic back: "Teacher, I didn't lie to you, I really came here to give something to others."

"Which one?" asked the female teacher.

"Nakano Mayzuki."

"Let me see."

The female teacher also felt that Luo Zhen didn't need to go to any sprint camp, and she was inclined to believe it in her heart.

She stared at the roster and found that there was indeed such a person, so she asked, "Is she in the same school and grade as you?"

"En." Luo Zhen nodded.

"That's very good."

"Hey?"

"If you have any problems in the future, let her come up and answer them."

"..."

That's a little bit wrong.

The mathematical induction method does not say that two friends in the same school and the same grade, one of them is a top student, and the other must also be a top student.

This is not rigorous!

Luo Zhen thought about it for a while, and was about to explain something, but he didn't expect that the female teacher had already started chasing people away: "Have you delivered your things to classmate Nakano Wuyue?"

This sentence is roughly equivalent to "if you finish delivering your things, go away quickly".

Luo Zhen had no choice but to run away, but just as he left the house, he heard the female teacher's voice: "Student Nakano Wuyue, come and answer this question."

He felt that he had blamed the meat bun.

Chapter 102 "Teacher is Awesome!" and Dongpo Meat

Luo Zhen left the sprint camp at an embarrassing time, and already missed the time to go back to prepare lunch.

Because I usually stay in bed, this kind of "missing" has become a routine during the summer vacation, so it will not have a particularly large impact, just eat a ready-made meal outside.

He kept moving forward under the bright summer sun, and the sticky air made it swelteringly hot.

Ding~~dang~~

The crisp and melodious church bells sounded.

Located near the busiest intersection in the world, there is a high-end hotel "Shibuya Excel Hotel Tokyu", where a wedding must be held.

Tsk, rich man!

Luo Zhen could feel the gorgeous aura, and the sound of everyone's blessings could also be heard through the wall.

This was the first time he met a rich man who held a large-scale wedding in the city center, so he decided to stop and observe for a while.

Luxurious, elegant, picturesque...

But for some reason, a black shadow seemed to appear in the corner of the line of sight, completely absorbing the attention. This kind of gravitational force is like a black hole, and even the sunlight has twists and turns.

In the happy wedding scene, there is an obsession close to resentment.

It could only be that person.

……

"It would be nice if you got married soon too~"

"It should be Xiaojing's turn next, right?"

"Xiaojing, Auntie has found a good man for you again. There will be no problem this time. Would you like to meet and see?"

……

Every time everyone spoke to the black shadow, she trembled convulsively.
