After taking the advice, I became a top student.

[Host detected copying 48 pages of math textbook, total task completion 83.7%, Nutrients +200]

After evening self-study ended, Chen Mo nodded in satisfaction upon seeing the prompt in front of him.

This method earns points through hard work, but it's effective in the long run and is quite practical. Furthermore, the copying process does allow you to notice many previously unnoticed knowledge points, so it's not a waste of time.

The most crucial element is the special skill that can be obtained after completing the task: [Photographic Memory]. This is Chen Mo's biggest motivation for persevering in copying books.

Back in his dorm room, Chen Mo, as always, began reviewing the knowledge points he had learned that day, and then continued copying from the book.

As his attributes improved, he needed less and less time to review knowledge points, allowing him to spend more time copying books. Now, his book copying progress is getting faster and faster.

The six-person dormitory room was brightly lit. At this time of day, everyone would usually be either playing on their phones reading novels or playing King of Glory.

But now, all six of them are sitting at their desks, some reading books, and some doing their homework.

They tried continuing to play on their phones, but whenever they saw Chen Mo sitting there studying diligently without wavering, they felt guilty.

The anxiety of everyone else working hard while you're having fun is even more unbearable than heartbreak.

Of course, there are also those with strong willpower, such as Guo Chao, who is currently lying in bed playing King of Glory, completely unaffected by his roommate's intense competition. Of course, he also wore headphones, so as not to disturb his roommate.

"Old Huang, how do I do this problem?"

At 10:30, with the lights about to go out, Li Ze couldn't sit still any longer and asked Huang Qinghua next to him for help.

"I know which question you're talking about, don't ask me, I don't know either."

Huang Qinghua didn't even look up, just kept scribbling on the draft paper. He was also a little frustrated, "I've been doing this for half an hour!"

"what?"

Li Ze opened his mouth wide.

Huang Qinghua is considered quite good at math in the class, so how come even he can't do it?

"Why did the teacher assign such difficult homework? Who's going to be able to hand it in tomorrow?"

Another roommate was also wailing.

"I don't know about others, but Shen Qingyi definitely will. Why don't we go ask the class representative for questions tomorrow?"

Suddenly, Huang Qinghua raised his head, his eyes bright.

When did Chen Mo's academic performance begin to improve rapidly?

Didn't it all start with asking Shen Qingyi questions?

Private tutoring for top students is sure to have amazing effects!

"Do they even acknowledge you?"

Li Ze immediately poured cold water on his enthusiasm.

Oh too.

Huang Qinghua's arrogance vanished instantly, and he looked once again at the homework assignment that had been driving him to the brink of despair.

Li Ze looked thoughtfully at Chen Mo beside him.

"Chen Mo, have you done your math homework?"

He asked tentatively.

"I did it," Chen Mo nodded.

"Did you do this question?"

Li Ze's eyes lit up, and he took the textbook to Chen Mo's side.

"Hmm." Chen Mo nodded again, but he was a little puzzled. He had also heard Li Ze and Huang Qinghua's conversation earlier. Could this be the problem they were talking about?

That's not difficult at all.

"Let me see it, let me see it."

Li Ze said happily that it was very exciting to be able to solve the problem that had been bothering him for more than an hour.

Not only him, but Huang Qinghua and several other roommates also gathered around. Although they had already given up, they still wanted to see the correct answer.

Okay, I'll copy some homework while I'm at it. At least I need to finish tomorrow's homework first and get a good night's sleep.

Chen Mo naturally wouldn't refuse and handed over his workbook.

tanα=2.

"what?"

When they opened Chen Mo's notebook and saw this answer, all five of them fell silent.

After a long pause, Li Zecai composed himself and said, "Chen Mo, I think you're being too hasty. Even if you're copying homework, you can't just copy the answer without writing out the process. That's too perfunctory and disrespectful to the teacher."

He clearly believed that Chen Mo had copied Shen Qingyi's answer.

"I didn't copy. These kinds of questions are obvious at a glance, so there's no need to write out the steps."

Chen Mo wouldn't bother with anyone else, but Li Ze was different.

After the entrance exam results came out, others either mocked him or ignored him, but Li Ze still treated him as a good friend as before.

"You mean you came up with this answer yourself?"

Huang Qinghua didn't know if the answer was correct, but looking at Chen Mo's confident look, he suddenly felt a little doubtful about life. He was the fifth in the class, and he couldn't do the question, but the last in the class could?

Although Chen Mo had solved a problem he couldn't solve in class last time, it was because he was distracted and didn't pay attention. But today was different; he had actually been thinking about it seriously for half an hour.

"Could you explain to us how to solve this problem?"

Li Ze spoke up again, feeling that he couldn't encourage his good brother's pretentious behavior. Knowledge is something that must be acquired through hard work; it only becomes your own once it's learned and internalized, and you can't fake it.

Chen Mo didn't waste any words. He had already taken the draft paper and started writing and drawing. "Actually, the question has already given a lot of hints. For example, the square root of five. In trigonometric functions, if you are given a square root, it is obviously meant to make you square it."

The people in room 304 exchanged glances.

This stance,

Chen Mo seems to really know how!

Although they had only just begun speaking, they already had some guesses from the moment they opened their mouths.

"So let's not worry about the details for now, let's square the original expression first."

陈末一边说，一边在草稿纸上写下，cosα^2+4sinα^2+4sinαcosα=5.

"When I see cosα^2, I immediately think of sinα^2, because they add up to 1. And look at this formula, isn't it just the expansion of the difference of squares and the sum of squares?"

「所以，我们再构造另一个式子，令sinα-2cosα=x，把这个式子一平方，我们就得到sinα^2+4cosα^2-4sinαcosα=x^2，然后两个式子相加得到1+4=5+x^2.」

"This gives us x=0. What is x? It's sinα-2cosα. So sinα-2cosα=0, and tanα=2, right?"

Dormitory 304 was completely silent.

Chen Mo's five roommates stared blankly at him.

Chen Mo finished explaining the problem in less than 30 seconds, but the others had been thinking about it for at least half an hour.

Li Ze looked at Huang Qinghua. He wasn't trying to verify whether the question was right or wrong. After Chen Mo's explanation, he could understand that the answer must be correct.

The other roommates exchanged glances, sensing that Chen Mo seemed genuinely different.

You weren't like this before.

Li Ze said with some melancholy.

Although he had comforted Chen Mo because of his poor performance in the entrance exam and genuinely hoped that Chen Mo's grades would improve, he still felt a little uneasy when he suddenly discovered that Chen Mo was developing into a top student.

"Wasn't it like this before?"

Chen Mo was taken aback.

He quickly realized, "That's right, I could solve similar problems before, but I could never reach this level."

Therefore, it's about insight!

With his current insight, he quickly found the source of the problem.

This question turned out to be more complicated than it seemed!

Chen Mo only realized this now, belatedly.

This insight is so useful!
