Chapter 109: Vicious Thoughts
Translator: Atlas Studios Editor: Atlas Studios
Han Wen was furious and left with Zhou Rong. Usually, his grades in class were not too bad. He was slightly below average and the teacher had never said anything about him. He felt good about himself. But today, a person who was younger than him was teaching him. He listened carefully and actually did not understand. This was something he could not accept. He could choose not to study, but if he could not accept that he had yet to master it! He secretly made up his mind. From today onwards, he would study hard and strive to understand next time!
The first class in the afternoon was math class. As soon as Liu Kai entered the classroom, he saw Yue Xin who was awake. He raised his eyebrows and his face was filled with surprise. He was not someone who would mistreat his own people. He had to know what he wanted to know. He asked Yue Xin directly, “Why aren’t you sleeping?”
Yue Xin was dumbfounded.
Seeing that she did not answer, Liu Kai thought that she did not hear him clearly. He asked again, “I said, why aren’t you sleeping today?”
Only then did Yue Xin answer, “In order to sleep well at night.”
Hearing the answer, Liu Kai inexplicably felt that it was very reasonable. Looking at Yue Xin’s peaceful expression, he turned back to the podium and wrote a question on the blackboard. Then, he said to Yue Xin, “Yue Xin, come and solve this question. If you can’t solve it before class, stand and listen in class later.” He wanted to see if Yue Xin was really awake or not.
The questions on the blackboard were very concise. Prove tani> 3/2.
This was a conventional proof question, but it was undoubtedly beyond the scope of a junior high school student who had only learned the basics.
Yan Ye took a look and suspected that Yue Xin had offended the form teacher. Otherwise, why would he come up with such a question? If this question was to be solved by conventional methods, it would first have to be cut at x: 11/3 and y=tanx. Then, it would have to be derived using the assumption of f(x) to prove that the monotony in the defined domain decreased. Only then could it be proved that tani> 3/2.
However, there were only five minutes left before class started. If she had not mastered all the knowledge needed for this question and was not very familiar with this kind of question, it was impossible for her to solve it before class started. Yan Ye could not help but worry for Yue Xin.
However, if Yue Xin couldn’t solve this question later, wouldn’t he have a chance to talk to her by explaining the question to her?
No, no, no! How could he think that way? How could he have such a vicious thought? He actually cursed his classmate! Although this question was indeed beyond the scope and not many students in the class could solve it, he could not have such a vicious thought!
Yue Xin looked at the question on the blackboard and only had one sentence in her mind. “If you can’t solve them before class, stand and listen in class later.”
Standing and listening… Standing for a class was too tiring. No, no, definitely not! She was only 12 years old. She was at the age where she didn’t think about anything and didn’t do anything. In order to accumulate energy for her future jail time, she definitely couldn’t waste her energy on standing in class. She wanted to sit in class!
At this moment, a fighting spirit surged in Yue Xin’s heart. She went to the podium, picked up the chalk, and looked at the questions a few times. Then, she closed her eyes and searched for relevant knowledge points in her memory, learning them now.
Yue Xin held the chalk and stood there for a minute without moving. Liu Kai’s heart turned cold. F*ck! Could it be that this little girl couldn’t solve it? If she was really punished to stand for a lesson, Brother Yue wouldn’t beat him to death, right?
He couldn’t be blamed for this. It was Brother Yue who said that Yue Xin was a math genius. He was misled. If not for this, he wouldn’t have come up with such a question! However, it was fine. If she really couldn’t solve it, he would say that he deliberately used this question to refresh everyone. It was fine.
Just as Liu Kai was comforting himself, Yue Xin finally started writing.
From the beginning to the end, it was as smooth as flowing water. In less than a minute, this question was solved.
It might not be accurate to say that she had solved it. It should be said that she had finished writing it. The answer was in her mind. She had only moved the answer in her mind to the blackboard.
When Yue Xin finished writing, the class bell had yet to ring. Liu Kai looked at the answer on the blackboard and was shocked. Yue Xin actually used Taylor’s inequality formula to reduce instead of an ordinary solution. If this question was solved using an ordinary method, it would have to be converted with at least five or six lines of equations, but now, Yue Xin only used three lines to solve it.
Liu Kai stared at Yue Xin’s answer and checked it several times before finally confirming that her answer was correct. When he turned around, he saw Yue
Xin staring at him obediently, as if she was asking with her eyes, “After solving it, can I sit down now?”
Liu Kai felt that he had grasped something, but this feeling disappeared in a flash. He did not grasp it, so he waved his hand and let Yue Xin go back.
Yue Xin returned to her seat and heaved a sigh of relief. Fortunately, she didn’t have to stand anymore..
