Xueba, I beg you to go and escort him quickly!

"3/4 cycle is 3/4 circle."

Xu Heng spent a round at random.

"Put this circle on the way to the question, and compare the areas."

"Obviously not?"

Even Yue Pingting could tell, "No, this cycle is bigger than the one on the way to the title!"

Xu Heng continued, "So..."

"Wait a minute! Xu Heng! Wait a minute, I don't understand the previous cycle."

The voice was very weak, Yue Pingting said, "I'm sorry... I didn't mean it, I didn't get confused."

Xu Heng explained patiently.

Originally a very simple question, I talked for three to five minutes.

Yue Pingting smiled foolishly, "Understood!"

"Okay, let's continue."

"D is wrong, so in ABC, C is the longest. If divided, it is 2/3 cycle, which can be divided into 1/2 cycle and 1/6 cycle, right?"

Xu Heng's thoughts jumped.

Yue Pingting and the others stared at each other intently, and each time they recovered after a few seconds and nodded frequently.

Every time Xu Heng said something, he had to pause for a few seconds to let them digest it.

"understood."

"Okay, follow the same pattern, continue..."

"..."

"Finally, what is the answer, do you understand?"

Yue Pingting's eyes lit up, "C!"

Xu Heng, "Yes."

"Hiss...understood! I will!"

Yue Pingting almost clapped her hands excitedly.

The other students frowned, "This seems to be different from what the teacher said... In class, the teacher said similar questions, which seemed completely different..."

"Xu Heng, your second method, what kind of angle method, doesn't seem to be taught by the teacher in class."

Xu Heng, "Teacher's method? What method?"

Suddenly Xu Heng realized that the third method, which is the oldest and most conventional, is also relatively speaking, the method of popularizing the public.

But according to the teacher's method, although it is safe, it takes more time.

"Cough, cough, cough!"

"For some questions, it will take a long time to follow the teacher's standard thinking. These are multiple-choice questions, so they should be treated in a selective way."

"Let's continue with the chord cutting method."

"Start from the picture..."

Xu Heng began to draw on it with a pen.

Talk and point out.

"Draw a circle, if it's here for the longest time..."

"..."

"This is the tangent of the arc, and this must be the center, right?"

Everyone was stunned, and it took a while to get confused, "Mmm, yes! Yes!"

Xu Heng continued.

Yue Pingting and the others listened very carefully, even more seriously than what the teacher said in class.

Never been this serious.

"Here, and this, added together, right, is 2/3 of the cycle of C."

Topic is over.

Everyone breathed a sigh of relief.

Eyes light up.

These few students who were watching were not considered the students with the worst grades in the class. They were self-motivated and listened carefully in class, but their grades could not be improved.

They understood what Xu Heng said.

"It feels like another door has opened!"

"Open the door to a new world!"

"No wonder Xu Heng got full marks in the exam!"

"Can you still do this question? If you add the teacher's method, will there be three methods?"

"right……"

Several people were amazed, get out of class was over.

Xu Heng and Yue Pingting left.

The students in the first few rows were really curious.

Although they have made it, but the mood of seeking knowledge makes them take the initiative to ask.

"Is there another way?"

Feng Shui turns around!

This group of students whose grades are not very good, because of Xu Heng, also passed the addiction of being a top student!

Cool!

Back in the dormitory, one of them rushed directly into Xu Heng's dormitory.

"Xu Heng! Thank you! Thank you so much! You made me a top student for once! It's so cool!"

Xu Heng, "?"

"The top few students in the class all came to ask me questions, which scared me to death!"

"My legs are floating! After I finished telling them, they were all very excited, petted me and smiled, and said thank you!"

"Thank you is secondary! The main thing is, the feeling of them bowing their heads to ask you the question is so cool!"

"That's the existence of the top few in the class!"

"They actually took the initiative to ask me the topic! I can brag about this matter for a long time!"

"Damn! Studying is so cool! You know a lot, and you are so popular at school!"

"..."

Coming and going like the wind, this guy is in a hurry.

The roommates stared at Xu Heng collectively.

Xu Heng shrank his neck, "What are you doing! Why are you staring at me all the time!"

"Xu Heng! Please guide me!"

"Teacher Xu! Please submit the questions!"

"Xu Heng! How to do this question?"

Xu Heng, "Let me go, I want to sleep!"

Xu Heng felt like he had a nightmare, and the poor students in the class started to study actively.

What's worse, he taught them over and over again, because their foundation was too weak to teach them at all.

"call……"

Xu Heng got up, he thought about it carefully, this is not a dream, this is the group of roommates last night!

A chill.

Xu Heng washed up and went to class.

He gradually got used to Yue Pingting bringing him breakfast.

"Today is rice balls and soy milk!"

in physics class.

Qin Fangming walked into the class with great interest.

"Students! What happened to the questions left in the last class?"

The students all laughed smugly, and some even took pleasure in other people's misfortunes.

The classmate who didn't like to look up before dared to look at him directly today.

"It's so strange!"

"Can you do it all?"

Everyone said in unison, "Yes!"

"Hey! Who will stand up and tell me?"

A classmate whose grades are not very good but who likes to show off stood up, "Teacher, do you want to hear the kind of problem-solving ideas?"

Qin Fangming was confused on the spot, "How many kinds do you have?"

This classmate, "Not counting the similar body types you taught in class, there are two."

Qin Fangming frowned, "Hey! Tell me!"

Qin Fangming's eyes lit up when the classmate described the two methods that came from Xu Heng's mouth.

"Who told you that?"

"he!"

"Who told you?"

"Yue Pingting!"

"Yue Pingting, what about you?"

Yue Pingting stood up, pointed to Xu Heng who was lying beside her, and was about to speak loudly.

Qin Fangming, "Hush! I was disturbed! I know!"

"Okay! Very good! Now that everyone knows, it will be easy for me to go to class!"

Qin Fangming was extremely relaxed, looking at Xu Heng's seat, he was even a little excited.

At the end of the day, Xu Heng slept with some headaches.

Swipe your phone, watch TV, read novels, play games...

sleep again!

In order to sign in, Xu Heng usually would not go out to play football.

"Xu Heng, I really envy you, it's the same as pension!"

Xu Heng waved his hand, "Not at all."

Perhaps in the past few days, what made Xu Heng slightly interested was the communication with Wu Liubai and learning from each other.

Since Zhao Gensheng realized Xu Heng's excellence, his attitude has been corrected a lot.

The more he looked at Xu Heng, the more surprised he was.

He also shared some things in his thesis with Xu Heng.

"Mao Sai suddenly! Thank you, classmate Xu!"
