Chuanshu Group's favorite: burn a kiss between the eyebrows of the villain boss

Study room on the third floor.

Ye Jinshu's concentration was entirely on her math paper, and she had already left Jiang Chengjue downstairs out of the blue.

The little girl seems to be trapped by a math problem. She is holding a black pen in her right hand and doing calculations on the draft paper. No, there is a problem with the way of solving the problem. At this point, she is stuck. She doesn’t know how to proceed. .

The little girl racked her brains and was unwilling to look at the answer. She poked her own cheek with the end of the pen with the cap inserted in it. What can be done?

Are the extreme points shifted?

She started to calculate on the draft paper again... She didn't notice until Jiang Chengjue gently opened the study door and came in.

The little girl was immersed in her own sea of ​​questions, Jiang Chengjue glanced at it, and raised her eyebrows. It seemed that he was fighting wits and courage with her elder brother downstairs to marry her, but the little girl was peacefully intimate with homework in the study We got in touch.

The big villain's lips curled up, but he liked Ye Jinshu like this very much. She was more beautiful than ever when she was serious, and his little girl was still a person who loved learning.

He put the computer on the other side of the desk, and walked slowly behind the little girl. Involuntarily, he also wanted to see what kind of questions made the little girl write so much that she didn't even know that a big living person like him came in. .

Oh, it turned out to be the last big question in the math paper, the derivative question...

Ye Jinshu couldn't help giving up at last, "Well, what method should I use to solve this question?"

She sighed, "Let's see the answer."

Originally, I wanted to do it by myself, but I didn't have the ability.

After she was in the third year of high school, she always wanted to get a full score in mathematics, but she never achieved it. Fu Jingchi, on the other hand, got a full score in the third year of high school.

She was very envious, so she worked harder.

Just as she took out the answer, she wanted to turn to the corresponding question, but Jiang Chengjue behind her said, "Can't you do it?"

⊙?⊙!

Ye Jinshu was startled when she heard the voice, sat on the chair and turned around, looking up at him, "When did you come in?"

"It's been a while, but you didn't notice it." Jiang Chengjue pulled out her answer, "Don't rush to read the answer, do other questions first."

Ye Jinshu looked confused, "Ah? Why? And what are you doing with my answer?"

"Put the answer here first, and also, show me your math book and tutoring materials."

Ye Jinshu was even more dazed, with a big question mark on her face. Although she didn't know what he was going to do, she still got up, "Wait for me, I'll go to my room to get it."

"En." Jiang Chengjue nodded, and sat down opposite her.

After a while, Ye Jinshu handed him the math book and math tutoring materials, "You don't want to learn math, do you?"

"Why not."

"Ah? But don't you still have work to do? I'll just do my homework by myself. Don't let me interfere with your work." After Ye Jinshu finished speaking, she just wanted to go back to her room to continue her homework. Pulled over by Jiang Chengjue, he gently squeezed her fair and slender fingers with his big palm, "I won't be disturbed by you."

Ye Jinshu looked at the face of the big villain, her heart thumped, hey, he was always so kind to her.

"Then you want to read the book and help me solve the problem?" Ye Jinshu felt a little unlikely, after all, the big villain hasn't touched these textbooks for a long time, right?

Where do you remember the contents of these books?

She has read the original book, so she naturally knows how high the IQ of the big villain is. She has completed all the courses in college before, but after that, she chose to join the army, became a fearsome officer, and climbed step by step to become the overlord of Continent E. status.

"Well, the knowledge in high school is not a problem for me. It's just that I haven't touched it for a long time, and I have forgotten it. Wait for me to go through the book." Jiang Chengjuan squeezed the little girl's soft hand again, "Okay Okay, you can continue to do your homework, and wait until I finish it."

"Ah, good." For some reason, Ye Jinshu actually believed it, believing that the big villain really has the ability to help her solve problems by reading books and reviewing.

She returned to her place, picked up a physics exercise paper and started to work.

The study room is very quiet, only the slight sound of turning the pages of the book, and the "rustling" sound of the little girl scratching the draft paper with a pen...

"I'll tell you about that question just now." Jiang Chengjue walked over holding the math paper she just had.

Ye Jinshu was furious, aha?Is he not joking?

She thought that no matter how powerful he was, it would take at least a few hours to read the content of the derivative, right?

Never thought that he had finished reading the multiple choice questions of the physics paper before she finished it?The topic also knows what to do?

"Jiang Chengjue, are you crazy in IQ?"

Jiang Chengjue, "..."

"What nonsense?" Jiang Chengjue tapped the little girl's head, "Okay, let's look at the question—" He took a pen to draw several parts of the formula on the question of her paper, "Look, there are The part with exponent and the part of logarithm, and then think about the relationship between the two, don’t you see the idea?”

Ye Jinshu's mind was running fast, and she spoke with difficulty, "I have always wanted to find the extreme value with an infinite approximation method, and finally prove the equation, but - there is no way to succeed, and there is something in the middle that I can't prove."

Jiang Chengjue tapped the little girl's head again, "Who told you to use the method of infinite approximation here? Since you know that the method won't work after you try it, why do you continue to think about it?"

Jiang Chengjue spoke mercilessly, "If you're like this, even if you think about tomorrow, you won't be able to solve this problem."

Ye Jinshu, "..."

"Because I have no other ideas, I think the method of infinite approximation is the easiest and best way to do derivative problems..."

"When doing problems, especially mathematics and physics, you should not be brainless. You must use your knowledge flexibly and learn to infer other things from one instance. You have no scientific thinking at all."

Ye Jinshu, "..."

What should I do, suddenly a little wronged?

"You...can't you be gentler?" If it was the teacher who said this to her, Ye Jinshu would not feel anything wrong, but if this person were Jiang Chengjue, she would somehow want to be petty and want him to be more gentle A little bit, don't say she is dead-headed.

Seeing the little girl's beautiful almond eyes looking at him aggrievedly, Jiang Chengjue's heart suddenly trembled, he couldn't see her cry, "Okay, okay, I was wrong, I'll be more gentle."

Jiang Chengjue simply sat down beside Ye Jinshu and stroked her hair, "Look carefully, what are the characteristics of ex-1 and ln(1+x) here..."

Ye Jinshu followed his train of thought, and slowly, suddenly realized, "Ah, I see, is it the way to use derivative scaling?"
