My Identity As A Schoolmaster Has Been Exposed

Lin Mengjiao stared at him blankly, speaking unfavorably: "Wh, what? What method? There are two other solutions?"

Several students next to him heard Xu Cong's words, the expressions on their faces suddenly condensed, and immediately asked: "Really? Is there so many methods for this question left by the physics teacher?"

It's really surprising. This carelessness made the voice a little louder. It was heard by the classmates in the first few rows, and many people looked at it.

Soon they also learned what was said in the back row, which immediately aroused the curiosity of many people: "Several methods? Are there any?"

Lin Mengjiao swallowed, and said to Xu Cong expectantly, "Or, let's talk about it all."

Xu Cong doesn’t care, anyway, it’s all about teaching. To talk about one more method is to say a few more words, so he started to analyze this question: "Then talk about the special value method first. The special straight method is relatively simple. The next four options..."

Lin Mengjiao suddenly panicked when he saw him being such an actionist, and said quickly: "Wait, will it start so soon? Wait for me! I'm not ready yet."

She took out the pen and paper from her schoolbag and said, "Okay, let's get started!"

Xu Cong looked at her speechlessly. This is just a question. Is it so grand?

He said contemptuously: "It's not a problem, don't be like this."

Lin Mengjiao hadn't spoken yet, and several classmates nearby shouted, "Be yourself, Xu Cong!"

Xu Cong smiled at them and expressed understanding. He cleared his throat and said again: "For the special value method, look at option D first. This is the largest. This cycle can be regarded as (2Tm)/qB, so This time can be reduced to 3/4 cycles."

"A 3/4 cycle is 3/4 circle." At this point, Xu Cong drew a circle on the draft paper to make it easier for them to understand.

"Look, when you put this circle on the way to the title, the area is obviously wrong?" Xu Cong looked up at them and said.

Lin Mengjiao saw him analyze this way, she immediately noticed it, and immediately replied: "Well, this option is wrong. This cycle is larger than the one on the way to the question!"

Xu Cong saw that she understood, so he continued: "So..."

"Wait! Xu Cong! Wait a minute, I know this graph is wrong, but I don't understand the previous cycle. Can you tell me how to calculate it?"

Lin Mengjiao's voice was very weak, and she immediately said in shame: "I'm sorry I didn't mean it, I didn't get confused."

This can’t be blamed on her. Physics is inherently difficult. In addition, her academic performance is not very good, and many fragmentary knowledge points are not well mastered. Therefore, it is normal that Xu Cong can’t keep up when explaining.

Xu Cong didn't blame her. Xu Cong knew what level she was. He was very patient and continued to explain the following precautions.

So after talking about this originally very simple question for three to five minutes, Lin Mengjiao smiled stupidly, "Understood!"

Xu Cong let out a long sigh of relief. It was not easy. He took a sip of water and said, "Okay, let's continue."

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

Lin Mengjiao watched intently, every time it took a few seconds to slow down and nodded frequently.

No way, although this question is easy for Xu Cong, but for them, it can be said to be clueless.

Therefore, every time Xu Cong talks about a point of knowledge, they always know it later and need to think about it. After Xu Cong knows this, every time he talks about it, he must pause for a few seconds for them to digest it.

"Understood." Several people said quickly and suddenly.

"Okay, follow the gourd and draw a scoop, let's continue..."

...

"Finally, what is the answer, do you understand?" Xu Cong looked up at several people again, the pen in his hand was still turning.

After Lin Meng petite turned her head, her eyes lit up and she quickly said, "C!"

Xu Cong said with satisfaction, "Yes."

"Hi...understood! I will!" Lin Mengjiao almost clapped her hands excitedly.

The other students around frowned, and at this time they also expressed their own opinions: "This seems to be different from what the teacher said. When in class, the teacher talked about similar questions, which seemed completely different..."

"Xu Cong, what about your second method, which is the angle method you just mentioned. It doesn't seem to be taught by the teacher in class. Can you talk about it?"

Xu Cong glanced at the classmate who was talking, and said, "Teacher's method? What method?"

After Xu Cong said this, he realized what kind of method the teacher used. It should be the oldest and the third method that sticks to the rules. It is also relatively speaking, popularizing the public.

Because the teacher is dealing with all students, the method used to solve problems in class is the basic solution in the textbook, which is acceptable to all students.

But according to the teacher's method, although it is safe, it takes more time, so Xu Cong directly told them these two.

So Xu Cong began to explain: "Cough cough cough!"

"Some questions, if you follow the teacher's standard thinking, it will take a long time to waste, and this is a multiple-choice question, so we must use the method of choice."

After Xu Cong finished speaking, he glanced at them again and said to them: "Next we will continue the chord cutting method, starting from the picture..."

Xu Cong drew on it again with a pen, and pointed out the key to solving the problem while talking: "Let’s draw a circle for this problem first, so it’s easier to understand the analysis. If it’s here for the longest time..."...

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

Everyone was stunned for a while, and then they came over in confusion for a while, and said one after another: "Yeah, yes! Yes!"

Xu Cong saw that they understood, and then went on to say that Lin Mengjiao and the others around listened extremely seriously, more serious than what the teacher said. They had never been so serious.

"Here, and this, add it together, right, it's 2/3 cycles of C..."

Xu Cong's second method took several minutes to finish the topic. After hearing it, everyone breathed a sigh of relief and their eyes lighted up.

The other onlookers were not considered the most scumbags in the class. They were motivated and listened carefully to class, but their grades were not up.

They can understand what Xu Cong said, and Xu Cong's two methods are simpler than what the teacher said, and they understand it faster.

After listening to Xu Cong's method at this time, several people said one after another:

"It feels like another door is opened!"

"Opened the door to a new world!"

"It's amazing, no wonder Xu Cong can get a perfect score!"

"Is it still possible to do this for this question? If the teacher's method is added, would there be three methods?"

"Yes, too strong..."
