Chapter 95 Problem Solving
While Li Yilan was staring here, Shen Ye and Mu Xiaoxi in front were passing a notebook to each other, and the notebook contained the whispers between the two of them.

[Mu Xiaoxi: What do you like about me? 】

[Shen Ye: Ah... I like your long black hair! 】

[Mu Xiaoxi: Besides this? 】

[Shen Ye: As long as it's you, I like it, and I like it for no reason. 】

[Mu Xiaoxi: You are so greasy, big pig's hoof. 】

[Shen Ye: Are you leaving?It's not good to stay here, is it? 】

[Mu Xiaoxi: Yes. 】

After discussing with each other, the two slowly got up.

When Mu Xiaoxi got up, she didn't forget to take a sneak look at Shen Ye, and then walked directly towards the door with a shy expression on her face.

The speed was neither fast nor slow, just enough for Shen Ye to catch up.

Shen Ye looked at his shy face, and instantly had a sense of seeing the ancient King Zhou.

"Damn it, this is such a horrible feeling!"

Shen Ye shook his head, got rid of the thoughts in his mind, and immediately chased after him.

Anyway, he had to keep up.

Li Yilan, who was sitting at the back, immediately looked up when she heard the voice.

She saw Shen Ye and Mu Xiaoxi walking towards the outside immediately, she immediately cheered up and wanted to walk up, destroying the chance of the two of them getting along alone.

"If you want to be alone, there is no way!"

After Shen Ye and Mu Xiaoxi left, only Liu Chao and Li Yilan were left in the classroom.

After Liu Chao looked around for a week and found this feature, he immediately walked towards Li Yilan. He couldn't let go of such a precious opportunity to be alone.

He has watched a lot of TV dramas, and he is very clear that it is easier to develop feelings under such circumstances.

In the TV series, Mu Xiaoxi fell in love with Shen Ye because of such an environment, so he got up immediately, it was his own little plan.

Liu Chao didn't know that Li Yilan didn't care about him now, but wanted to leave with all her heart.

If he went over with the book now, he must be asking for trouble.

Without knowing anything, he walked over with a book and placed it in front of Li Yilan.

Li Yilan stood up and stepped out with one foot.

Seeing this, Liu Chao grabbed her arm with one hand and said, "Student Li Yilan, don't rush to leave. I need your help with something. You can see how to do this question. I don't quite understand it."

Li Yilan said coldly, "Let me go."

However, Liu Chao said with a bit of rigidity: "Today, if you don't teach me this question, you are not allowed to leave. Follow me to study hard. How can you show such an attitude at this moment? It hurts my heart too much."

Originally planning to do it directly, Li Yilan choked on this sentence.

After all, she was the one who took the initiative to ask others to study hard, but when the other party studied hard and came to ask her questions, she was impatient and wanted the other party to leave, which was indeed a bit wrong.

But she really has something to do!Very urgent!

Seeing his stubborn face, Li Yilan was going crazy.

Don't come early, don't come late, but at this time, I really know how to seize the time.

"Oh my God, who is going to take this bastard? Why is he so stubborn today? Where is his cute appearance?"

Li Yilan tried to break free twice, but couldn't break free, and finally had no choice but to sit down.

After all, after such a long delay, the two must have traveled a long distance.

It's too late for me to destroy the chance to get along now, so I might as well get rid of the bastard in front of me first.

Li Yilan immediately snatched the book in his hand, then pointed to the title and said: "Listen carefully, if you don't listen carefully, I will give you a book right away." Slap. Do you understand?"

"Yeah, don't worry, I don't need to listen to what others say, but I will definitely listen to what you say, and I won't let go of a word."

Liu Chao said sincerely, Li Yilan suddenly became numb, feeling uncomfortable all over.

She shook her head, immediately expelled this strange feeling from her body, and then started the lecture.

It's a pity that Liu Chao's academic performance is not good, and his foundation is very poor, so teaching is also very troublesome.

Even if he didn't let go of a word, he still couldn't understand it. He could only speak slowly from the most basic level, but how could it be possible to explain clearly in a short while?

As a result, the two mingled here for several minutes, but there was no result.

She had no choice but to do it all over again.

"Oh my god, look at the question again, y=(2-sinx)/(2+sinx), what are the characteristics of this, let me remind you, what are you asking for!"

Liu Chao said in a low voice, "The value range of sinx."

"and then?"

"do not know!"

"I don't know you big-headed ghost, simplify!"

Li Yilan angrily threw the book on the table and clapped it very loudly.

She immediately grabbed Liu Chao's ear and came over, then picked up a pen with the other hand and started writing.

She wrote and said, "Look, what happens if there is a (2+sinx) below and a (2+sinx) above? Will it be simplified, leaving only one sinx in this formula? "

"Why is it simplified? I still don't understand!"

Liu Chao looked at Li Yilan's angry look, and said these words carefully.

Seeing his pitiful appearance, Li Yilan didn't want to deal with him anymore.

She let go, and then explained: "If we want to make up (2+sinx), then we must subtract an extra two from it."

Like a curious baby, Liu Chao interrupted and asked, "Why do we need to subtract an extra two? I really don't understand this point, can you explain more?"

Li Yilan was expressionless, she was numb to the appearance of a curious baby like him.

“（2-sinx）要凑出（2+sinx）必须从sinx着手，也就是2-sinx=2-（sinx+2-2），这样是不是不变了？是不是和原来恒等了？”

"exactly!"

Liu Chao nodded fiercely, showing a suddenly realized expression.

After he understood this, he seemed to feel that his head was a little smarter.

Li Yilan showed a teachable look and continued, "Open the two and leave (2+sinx), that is, y=[2-(2+sinx)+2]/(2+sinx), simplify to get y =-1+[4/(2+sinx)], do you understand this step?"

"Understand, understand!"

Liu Chao felt that he had gained a lot of brains, and suddenly became enlightened, and continued: "Because -1≤sinx≤1, so 1≤2+sinx≤3, we can solve it by substituting it into the formula."

"Yes, if you have to use the square method to do it, it will become more troublesome. You have to learn to associate, and you have to become sensitive after learning. Do you understand this step?"

Li Yilan immediately felt a sense of accomplishment, she actually taught this idiot a lesson.

Liu Chao's eyeballs rolled wildly, and he greeted again and again: "Got it, got it."
