Chapter 112

It's a pity that I didn't meet the era of Ge Jun?

What does that mean?

Feelings: This classmate of yours still wants to be abused by that Uncle Ge to death?!

I don't understand, I don't understand!

The middle-aged invigilator slowly returned to the podium with his hands behind his back.

And Bizzie is here.

After adjustment, Bi Qi has regained a good attitude.

Forget it, it's simple.

The top student in the college entrance examination is destined to miss him, so he won't force it!

Happy college entrance examination!

It doesn't matter if the test questions are simple or difficult, the happiness is over!

…………

Bi Qi took a deep breath, lifted his pen, and his eyes fell on the test paper.

(1) Let the domain A of the function y=√(4-x^2) and the domain of the function be B, then

（A）（1，2）（B）（C）（-2，1）（D）[-2，1)

（2）……

Swept all the way.

In more than half an hour, Bi Qi pushed to the last two questions of the test paper.

20. The known function f(x)=x^2 +2cosx, g(x)=e^x(cosx-sinx+2x-2), where e≈2.178...... is the base of the natural logarithm.

(I.) Find the tangent equation for the curve y=f(x) at the point (π.f(π)).

(II.) Let h(x)=g (x)-a f(x)( a R), discuss the monotonicity of (x) and determine whether there is an extreme value, and find the extreme value when there is an extreme value.

Needless to say, the first question of this question is needless to say.

If it weren't even a group of people who didn't know this question, Bi Qi wouldn't know where he got the courage to step into the college entrance examination room.

The second question is not difficult, but a little more complicated.

Firstly, according to the stem, h(x)=e^x(cosx-sinx+2x-2)-a(x^2 +2cosx).

Derivative of h(x) yields h'(x)=2(e^x-a)(x-sinx).

Let m(x)=x-sinx, then m'(x)=1-cosx.

The monotonicity of m(x) on R is obtained.

Then, we discuss the two cases where A is less than or equal to zero, and A is greater than zero.

Finally, the monotonicity of h(x) is obtained, and the extreme value is determined.

so easy~~

The twenty-first and final question about elliptic curves.

In Bi Qi's view, the difficulty of this question is not worthy of such a finale position at all.

The first small question, find the eccentricity and you can easily get the answer.

The second question is that the simultaneous equation is calculated.

Except for the large amount of calculation, the technical difficulty is basically equal to nothing.

In less than an hour, Gu Lu completed all 21 questions in the entire set of test papers.

"It's boring, it's boring!"

Bi Qi smashed his mouth and smashed his mouth, looking excited.

Knowing that this math test paper was so unchallenging, Bi Qi might consider not taking the college entrance examination.

After all, such a set of test papers......

If he gets a perfect score, he can't prove how awesome he is.

But if you can't get a full score, it will capsize in the gutter, and there is a possibility that you will not be able to protect the night.

"Hey, check it carefully! Don't roll over in the fishpond bureau again. ”

It's still early.

Bi Qi looked around and found that everyone in the same examination room was still struggling with the questions of the test papers.

In order to avoid the embarrassment of not getting a perfect score, Bi Qi decided to check it a few more times.

The first time, no problem.

The second time, nothing was wrong.

The third time, this is who did the answer sheet, it is simply textbook-level perfection!

What? Did I do it? It's kind of weird, I'm embarrassed.

After checking it several times and making sure that there was no problem with his answers, Bi Qi looked up and looked at the time when the watch was hanging on the wall in front of the classroom.

16:10.

There are 50 minutes left until the end of the exam.

Feeling bored, Bi Qi lay on the table, and gradually, with the rustle of the tip of the pen rubbing against the paper in the classroom...... Fall asleep!

"Whew-" "Whew-"

A few minutes later, rhythmic rings echoed through the classroom.

All the candidates in the same examination room were stunned for a moment, and then they looked up with a confused expression.

The voice......

If they heard it right, it should be...... Snort!

Snore?!!

Somebody was sleeping.

Everyone's eyes searched the classroom, and then instantly locked on the figure lying on the table, sleeping soundly.

It's not ......

That's right, isn't that guy who just got so math that he banged his head on the table!

So, this is a complete abandonment of treatment tormented by math problems?

Everyone took pity on Bi Qi for a moment, then lowered their heads, and continued to answer the question.

"No, I'm going to have to struggle!"

In the examination room, a dead and alive student who was abused by math problems glanced in the direction of Bi Qi, and then clenched his eyes with a resolute gaze.

Compared to Biqi, he felt that he should still be able to struggle.

…………

on the podium.

The candidates in the same examination room heard it, so that the invigilator could not hear it.

The older middle-aged invigilator and the other young teacher looked at each other and were stunned for a moment.

With his seven or eight years of rich experience in invigilating the college entrance examination, to be honest, this situation is ...... It's the first time I've met!

This is the college entrance examination, the college entrance examination!

What a serious, tense occasion.

But someone fell asleep on such an occasion, this heart ...... How big is it?

The middle-aged invigilator reluctantly walked up to Bi Qi and knocked on the table,

"Classmates, wake up, don't sleep, this is the college entrance examination!"

"Ahhh

"Classmate, don't sleep!" the middle-aged teacher said in a deep voice.

"Huh?" Bi Qi was stunned for a moment, scratching his head, "But I heard my math teacher say that sleeping is allowed in the college entrance examination?"

The middle-aged invigilator instantly had a black line.

Who's that math teacher of yours? Remind students of the rule that sleeping is allowed in the college entrance examination.

This is so damn poisonous!

The middle-aged invigilator took a deep breath and forced himself to calm down, "It's good to be allowed to sleep, but you sleep and snore." ”

Bi Qi blushed with shame, and then apologized again and again, "I'm sorry, I'm sorry, I'm really sorry." I don't sleep, I don't sleep. ”

As he spoke, Bi Qi took out the answer sheet that had been filled up and made a look like he wanted to check.

Next to him, the invigilator who was about to leave was suddenly stunned.

Because of his casual glance just now, he happened to see the test paper that was full of written papers on Bi Qi's desk.

So, without thinking, he subconsciously asked, "Are you done?"

"Ahh Bi Qi nodded and shrugged helplessly, "It's just that I can't hand in the paper in advance, so I can only rely on sleep and play time." ”

The college entrance examination cannot be submitted in advance!

This is a point that makes Bi Qi very criticized, but this is a dead rule, and Bi Qi can only abide by it.

"Teacher, is there a problem?" asked Bi Qi, looking up.

"No problem. The invigilator suppressed the surprise in his heart and walked back to the podium as usual.

At five o'clock in the afternoon, the math test ended.

Bi Qi, who was tormented by time, was like a wild dog that had escaped from the leash, swooping out of the classroom and running out of the school gate.

But at this moment, a reporter stopped Bizzie's way.
