Generally speaking, the last big question in mathematics is the most complex question in the whole paper.

This question itself is not intended for ordinary students, but for those top students to pull away the score.

In this math exam, the last big question is a function problem.

Almost most of the students were empty, and those with slightly better grades only answered the simplest of the first small questions in this big question.

The third question at the end, in the entire second and fifth classes of high school, no one can even make it completely!!

Yuan Haoyu, who has been ranked first all year round, barely got the second question right.

Yan Xiaoke also thought of ideas.

But the results are still not calculated.

The answer to this question can be divided into five scenarios. If you can't understand it thoroughly and conditionally, it's hard to memorize the answers!

So Ou Dao wants to see what else Su Mu can do.

Today, he really doesn't believe in this evil!!

"I didn't write the last question."

Su Mu spread his hands, perfectly avoiding Ou Dao's doubts.

"I didn't get a perfect score."

Ou Island: "......"

"Uh...."

This kind of answer made him speechless for a while.

The main thing is that Su Mu shocked him too much.

He didn't react for a moment.

The two big questions behind Su Mu are indeed empty and not written.

"Okay, then you can go back to your seat first."

He sighed, seeming a little disappointed.

However, for Su Mu's learning change, Ou Dao's mind was still skeptical.

"Huh? Why don't you go? ”

Ou Island wanted to continue the class.

But he found that Su Mu did not leave the podium, but carefully checked the test paper there.

"I think I can try, this last question is quite interesting."

"I know, you suspect me of plagiarism, but if I really do this question, I should be able to prove my innocence, right?"

"I used to have a poor academic performance, but from now on I have decided to become a top student."

"It doesn't matter if you believe it or not."

"Lately, I've suddenly felt that learning has become more interesting."

Su Mu said calmly.

Now, he has more and more points, and his results are bound to get better and better.

It's better to get a preventive shot now, so that people don't look down on you every day.

"Do you really want to try??" Ou Dao asked in surprise.

"No one in the class got this question right."

"Hmm."

Su Mu nodded seriously.

Ou Dao sighed, thought about it, and finally agreed.

"Then I erased the answer here?" He pointed to the analysis written earlier on the blackboard and asked.

Ou Dao nodded.

It seems that I have forgotten the purpose of this class.

He was genuinely curious now.

Su Mu, could it be true that he has hidden so deep strength?

There was a loud bang in the class and the sound of flipping the test papers.

Maybe today's protagonist is too shocking.

Almost everyone's attention is focused on the class.

Especially those poor students who don't do well in grades, they don't secretly hide below to read novels.

Instead, he watched Su Mu pretending to be forced on the podium.

Even, some of them have an inexplicable sense of pride!

This is a rare representative of the poor life!

"This problem is a set of derivative and conditional functions...."

"First of all, we can easily figure out the answer to the first question, and conventionally, the first question is usually a kind of prompt that follows."

"Some students may think that it is not so easy, so I will explain my thoughts carefully."

"Personally, when I encounter a function problem, I prefer to draw a rough function graph first."

"And then substitute a few more important values, like f(0), f(1), and so on."

"Next ....."

Su Mu talked eloquently on the podium.

Completely ignored, the surprised gaze of the audience.

Moreover, he explained with a student's thinking, and many places were exhaustive.

Even the simplest places are given detailed explanations to take care of students who are not very good at math.

He doesn't ask if anyone understands, but secretly observes the eyes of his classmates.

There is no point in asking.

Only with eyes will not deceive people.

Once, what he hated the most was the questions of some teachers in class.

"Is there anything else you don't understand?"

"Bring it up if you don't understand."

"If not, we'll move on to the next topic."

But are there really so many students who dare to ask questions?

Can a teacher really delay the class for the sake of a bad student?

Even sometimes, some students with a poor foundation are no longer a problem of "where they don't understand"!

Rather, it's a question of "I don't understand it all"!!

Some teachers take inferences for granted.

Some students understood.

But some students will really listen to it with a confused face!!

By the time you react, the teacher has already gone to the end, and occasionally accuses you of not paying attention in class.

It's a vicious cycle of despair.

As a result, some students have lost interest in learning.

"Well, that's pretty much it."

After writing the last value, Su Mu put down the chalk, thought for a while, and continued to speak.

"I'll circle the main points of what I'm talking about... The first point is here... bring in the value of the function f(0)..."

"The second point..."

He circled the highlights with different colors of chalk and continued.

"In fact, there is another simple solution to this problem, which is to first convert the standard function into a trigonometric function image and use the image to parse it."

"Elective 3-5 has a formula for function transformation, which converts the ordinary coordinate system into a trigonometric coordinate system, so that the drawn image will be clearer."

"Of course, there are many other solutions, but they are all a bit out of the curriculum, and they are only courses that are studied in college."

"Teacher Sun, if you think I'm still plagiarizing, I have nothing to say."

Su Mu looked at Ou Dao without the slightest avoidance.

This is the confidence that belongs to a top student!!

"You...."

The audience was silent.

There is only the occasional action of the students swallowing saliva.

Yan Xiaoke looked at Su Mu in a daze, his eyes full of appreciation.

Ou Dao stood by the podium, his heart a little messy.

Su Mu, that's it??

Moreover, Ou Dao even felt that this Su Mu was even better than what he said.

What's the situation??

You can't be in the wrong classroom, right?

Or are you dreaming?

It's a pity that countless doubts are in front of the evidence on the blackboard, and the shattered body is incomplete.

Because, the answer given by Su Mu is the correct answer!!

None of the class got this question right.

This also means that Su Mu is not plagiarism!!

Whether he believes it or not.

Su Mu has already completed all his requirements.

That test paper was made by himself!!
