When the system encounters psychosis

Chapter 109 Two dogs?

In class, Zhou Pingsheng is teaching seriously, what is the law of sine and cosine...

As soon as Gu Xiaotian heard these ghosts pouring into his head, his first feeling was...a little like dozing off.

Su Qianqian turned her head to look at him and smiled, her expression seemed to be a bit of a squeeze.

This is probably a kind of aggressive method.

After Gu Xiaotian felt Su Qianqian's gaze, his self-esteem exploded immediately, thinking that I should not be looked down upon by this little girl!
So he began to listen attentively to Zhou Pingsheng's explanation.

Gu Xiaotian in this world has indeed missed too many lessons. Ever since he had a mental problem five years ago, he has never instilled knowledge in his mind.

However, this is not the case for Gu Xiaotian now, not only has he finished high school completely, but his grades are not bad.

Fortunately, the mathematical knowledge in these two time-spaces is similar. The reason is probably that many mathematical theorems were developed in the West. Although the environment in Huaguo has changed, it does not affect these.

As for history and Chinese, due to the difference in modern history, the content of modern history will be somewhat different.In the Chinese textbooks, the original articles of some modern literati have disappeared, such as Mr. Lu Xun, Mr. Zhu Ziqing...

But Gu Xiaotian is not afraid of these liberal arts knowledge, because his memory has long since been incomparable.

At this time, Gu Xiaotian began to calm down, integrate the mathematical knowledge in his mind, and then integrate it with what Zhou Pingsheng said.

It stands to reason that the knowledge Gu Xiaotian learned in high school has been around for a while, and his memory will be somewhat blurred.

But when he concentrated on sorting it out, Gu Xiaocai was surprised to find that the knowledge he had learned before gradually appeared in his mind clearly, like a deep memory that had been dusty for a long time. Once he touched it and opened it, he discovered it Never left, just fell asleep quietly in a corner.

"The law of sines, in a triangle, the ratio of the sine of each side to its opposite angle is equal; the law of cosines, in a triangle, the square of any side is equal to the sum of the squares of the other two sides minus the other two sides and their included angle Twice the cosine product of ..." Gu Xiaotian muttered softly in his heart.

He suddenly discovered that as long as he was willing to retrieve the memory, all the knowledge he had learned before would be clearly visible in his mind.

Gu Xiaotian couldn't help but secretly excited. If so, it's not impossible for him to surpass Su Qianqian in the future, but the difficulty will still be a little bit.

After all, this little girl is really a college bully! She scored 580 points on the 579-point test paper. From Gu Xiaotian's point of view, this is not human at all!

"Xiaotian, if you have any curious questions that you don't understand, you can ask me." Su Qianqian turned her head and said with a smile. She didn't think about making Gu Xiaotian's grades so good, but it's not harmful to know a little bit of knowledge.

"Well, I see." Gu Xiaotian nodded, his eyes still staring at the chalk that "swiped" on the blackboard last week on the podium, frowning slightly, his mind was constantly integrating the knowledge points he said.

After a while, a class is all over.

After class, Gu Xiaotian closed his eyes and thought for a while, then pointed to a topic that Zhou Pingsheng had just mentioned in the textbook: "Qianqian, I don't seem to understand how to solve this problem."

Su Qianqian turned sideways to glance at the topic, and then said with a smile: "This theory has a very low degree of difficulty, so it's very difficult."

"What? Shouldn't it be easy if the degree of difficulty is low? Why is it so difficult?" Gu Xiaotian didn't understand.

"Uh... Let me explain to you this way! If a set of 100-point test papers, the average score of students is 60 points, the difficulty coefficient of this set of test papers is 0.6, and if the average score is 90 points, the difficulty coefficient is 0.9, indicating that this set of test papers The test papers are relatively simple."

"So that's the case!" Gu Xiaotian thought for a while after hearing the words, and finally nodded suddenly.

"But Xiaotian, are you sure you want to solve this problem? Why don't you figure out the simple one first!" Su Qianqian persuaded with a smile.

"No, let's solve this problem!" Gu Xiaotian shook his head, he had already solved the previous simple problems with the knowledge he had learned before, so naturally he didn't need to bother.

He also felt that his mind was becoming more and more clear.

"OK then……"

As Su Qianqian said, she took a pen and paper and began to calculate and explain step by step...

This question is really complicated, and Su Qianqian didn't finish talking until the class bell rang.

After Su Qianqian put down her pen, she looked at Gu Xiaotian's frowning and thoughtful expression, and thought that he didn't understand at all, so she lightly smiled and comforted: "It's okay if you don't understand now, it will get better with time."

Gu Xiaotian nodded, and didn't say much, because he was still trying to integrate Su Qianqian's problem-solving ideas, and after a while, he probably understood everything.

Gu Xiaotian smiled smugly, and looked up to see the Chinese teacher Wang Yurong in class, wearing a black professional suit. Since she was "molested" by Gu Xiaotian that day, she no longer wore a white shirt and black bra.

At this time, Wang Yurong was explaining the ancient Chinese text "Lanting Collection Preface".

"Wang Xizhi was a famous calligrapher in the Eastern Jin Dynasty, known as the "Sage of Calligraphy". This "Lanting Collection Preface" is his representative work, so do students know the font of this "Lanting Collection Preface"?"

"It's running script." Su Qianqian replied, but her voice was so small that it could only be heard by Gu Xiaotian next to her.

When Gu Xiaotian heard the words, he immediately raised his hand and shouted, "It's running script!"

Wang Yurong froze for a moment, turned his gaze to Gu Xiaotian, couldn't help being a little surprised, then nodded with a smile: "Student Gu Xiaotian is right, "Preface to Lanting Collection" is a running script, and it is also known as "the best running script in the world" , in calligraphy, he and his son Wang Xianzhi are collectively referred to as "two kings."

"Er Wang?" Gu Xiaotian was stunned for a moment: "Such an awesome character, why does his name become so low when he combines?"

Su Qianqian: "..."

Wang Yurong's teaching method is rather interesting. While explaining the content, he then interspersed with introducing some short stories about Wang Xizhi, at least it won't make the students feel too boring.

Gu Xiaotian also listened quietly. Although he didn't know the truth or falsehood, some stories were quite interesting.

In the middle of the course, Wang Yurong saw that some students were not concentrating, some were wandering, and some were obviously wandering.

So she knocked on the podium to attract the students' attention, and then said with a smile: "Students, let's play a little game! I will say the first half of the ancient poem, and you will take the second half."

"Okay." As soon as they heard that they were going to play a game, most of the students immediately showed great interest.

Wang Yurong smiled and thought for a while: "There are 3000 beauties in the harem."

Gu Xiaotian slapped the table and said loudly: "An iron pestle can also be ground into a needle!"

Wang Yurong: "..."
