Chapter 423: Be a quiet student!

Chapter 423 Be a Quiet Schoolmaster!
Ye Chen was startled!
Do test questions as a game before going to bed! ?
This game is very skeletal!
While Ye Chen sighed, my sister had already taken out several sets of test questions from her schoolbag!
Ye Chen saw that Tianli 38 sets!
Five years of college entrance examination, three years of simulation!
Huanggang Haidian Three Find Out!
45 sets of Stars!
These are all resounding college exam questions!
Sister Ye Xin'er, sometimes when she can't sleep, she won't play the drama like an ordinary sister-in-law Liang, but she will do it!
brush!
Take out a set of questions and quickly do it!
Then, it was also given to Ye Chen!
"Brother, let's play it too!"
Have fun! ?
Ye Chen was startled!
Liu Zhi who saw this scene next to him was also shocked!
Do the questions and play?
Still college entrance examination questions!
Cattle!
Suddenly, Liu Zhi looked at his sister Ye Xin'er, turning into admiration!
This little girl is really extraordinary!
Ye Chen didn't want to mess with his sister's nature, so he directly picked up a set of questions and started!
It's a set of difficult math problems, Ye Chen wasn't really interested in it!
After all, he had just entered university, and after coming out of this book, he no longer wanted to do questions!
But he has a look now!
When I glanced at these test papers, my eyes suddenly lit up!
"Sisi..."
Ye Chen frowned and realized that it was very simple!
This topic is too simple! ?
Swipe!
Ye Chen just picked up the pen!
Highly difficult multiple-choice questions require repeated check and calculation of choices and judgments on the performance paper. In Ye Chen's eyes, it is just a glance, and the result can be produced!
This is simply incredible!
Although Ye Chen was also a high school student before, after all, he went to Jingcheng University, but he couldn't do that!
At this moment, in Ye Chen's eyes, these difficult test questions are as simple as elementary school students' math problems!
The brain is running at high speed, constantly calculating, giving answers!
As if it became a computer machine!
At this level of calculation, Ye Chen didn't feel the heat in his brain, and the cpu was not warm!
Everything is normal!
"incredible!"
Ye Chen sighed in his heart!
In a mere ten minutes, Ye Chen finished the college entrance examination paper, from beginning to end in one go!
Ten minutes!
You know, all the top picks are also capable of handing in the paper, or half an hour in advance!
And under Ye Chen's super secondary brain development, it was so easy!
The thinking is extremely clear, and the calculation is extremely correct!
This feeling is like a computer's cpu, from corei34130, directly upgraded to corei97980xe!
That's great!
After finishing it, Ye Chen put the pen aside!
At this time, Ye Xin'er next to her was stuck on the last question!
Ye Xiner frowned, and suddenly saw her brother!
Suddenly, it was startled!
"Is it too hard to write?"
Ye Xiner asked, then tilted her head and looked at Ye Chen's test paper...
At this glance, I was stunned!
Ye Chen's test paper is full of answers!
and......
After a glance, this answer is the same as my own!
More importantly, Ye Chen actually made the last big topic, the rarest one!
I am still stuck here!
"Do not……."
"Is it impossible?"
Ye Xin'er grew up with a small mouth!
"Brother..... How can you..."
"So fast!?"
Ye Xiner was blinded!
These questions, even for her, need to be checked on the performance paper!
But brother, a piece of paper is useless!
No waste of paper to the country!
The answer is perfect!
"No...this last one...you have figured it out!?"
"I can't write yet..."
Ye Xiner said in disbelief!
Could it be that brother, has always been hiding?
He has such a good brain power, so he doesn't need it! ?
If it was used for the exam that year, now it has been accepted by the world's top universities@?
"This last one..."
Ye Chen looked at Ye Xin'er and couldn't figure it out for a long time, so the guide said!
"Your thinking is a little off!"
Ye Chen frowned faintly!
"Look at mine, this is the easiest algorithm!"
Ye Chen said calmly!
"The question is like this. It is known that a parabolic chord PQ that passes the focal point F, the point R is on the straight line PQ, and the vector OR=1/2 (vector OP + vector OQ), the projection of R on the parabolic line is S, let α and β be the two acute angles in ΔPQS. Prove that sinα+sinβ≤radius 2"
"My problem-solving idea is different from yours!"
"First of all!"
"From the vector OR=1/2 (vector OP+vector OQ), we can get a small conclusion that the point R is the midpoint of the chord PQ!
And because the projection of R on the parabolic line is S, the projection of point P on the line is A, and the projection of point Q on the line is B, then we can draw a conclusion:
RS=1/2(PA+QB)=1/2(PF+QF)=PQ/2,
And because RS is ΔPQS for the midline on the PQ side, ΔPQS can be obtained as a right triangle, that is, α+β=90 degrees, so, in summary, your conclusion, tan[(α+β)/2]= 1,
tan(α-β)
=
tan(90-2β)
!
There is a certain degree of uncertainty, which may not be completely established, and is completely untenable! "
Ye Chen's words are easy and freehand, as if to say that 1+1 is equal to 2 as simple things, but in Ye Xiner's ears, it sounds like a thunderbolt!
"brother......."
At this moment, Ye Xiner looked at Ye Chen, her eyes flickering, as if she had seen something terrible!
The difficulty of this question is the difficulty of the last big question in the college entrance examination. It is quite difficult to solve it by myself, brother./.......
It's so easy! ?
Moreover, he said his own problem in a straightforward manner and gave himself a clear and incomparable thinking!
Isn't my brother a liberal arts student! ?
Later, liberal arts students who studied music, why, science is so good! ?
Suddenly, looking at Ye Chen's gaze, he became infinite worship!
"brother!"
"I have seen many so-called scholars and talents, but they are simply scumbags in front of you!"
Ye Xiner worshipped it!
"Unexpectedly, my brother is so powerful!"
"It's perfect!"
Ye Xin'er was delighted and proud!
Liu Zhi was completely stunned by the side!
With a snap, the plate in his hand fell to the ground and broke into pieces!
At the same time, growing up his ruddy little mouth, staring at Ye Chen blankly!
The dialogue and discussion between the two brothers and sisters just now has completely exceeded their own understanding!
She never thought that the two young girls who rented houses back then had reached such an extent!
"Now, to be a landlord, what education do I need? To understand the conversations of the tenants!?"
Liu Zhi couldn't help making a voice of self-doubt!
At this time, Ye Chen smiled lightly, hiding his fame!
Zhuge Liang, really amazing!
"By the way, brother!"
Suddenly, Ye Xiner's eyes lit up!
"Brother, you are so powerful! You are so fast!"
"You can definitely go to the national brain power contest I want to participate in!?"
"With my brother's strength, this year's champion is you!"
Ye Xin'er said with great joy suddenly!
