If this draft paper could be personified, it would definitely leave Wei Minghai in a huff.
It felt the greatest humiliation of its life!
As a draft paper, it was actually not used by others!
Zhang Ruiyun stared at Wei Minghai, the corner of her eyes twitching.
Wei Minghai was completely immersed in his thoughts.
If the fill-in-the-blank questions could still be considered acceptable without using the papyrus, then it would be too much if he didn't use the following questions!
In the equation, sin^2A-sin^2B-sin^2C=sinBsinC.
(1) Ask for A;
(2) If Bc=3, find the maximum value of the circumference of ADC.
Zhang Ruiyun didn't dare to blink. He was afraid of missing any details.
He was certain that Wei Minghai would definitely use the papyrus!
No matter what, this question required the use of papyrus!
Zhang Ruiyun narrowed his eyes. He was very confident in his judgment.
But-
Wei Minghai was stunned for about half a minute before he started writing.
He didn't even look at the paper beside him and immediately wrote:
Solution: (1) A=2 Pi/3
(2) The circumference of the ADC reaches the maximum value of 3=2 3 under the square root.
(There are two ways to solve the second question: the first is the theorem of sines, and the second is the theorem of cosines.)
In Wei Minghai's opinion, the answer that could be given directly was as simple as it could be!
Therefore, he might as well skip the process!
Even if he wanted to use a different way of solving the problem to give an answer, this question was really not worthy!
Zhang Ruiyun was speechless.
At this moment, Zhang Ruiyun did not know how to express what he had seen!
This question tested the application of the sines and cosines theorem of a triangle, as well as the identity transformation, image, and properties of a trigonometal function.
Although the question was not the most difficult, it was still a mid-range question!
However, Wei Minghai directly gave the answer and even gave two directions to solve the problem in disdain!
Not to mention ordinary people, even a real mathematics god would not be like this!
Too arrogant!
At the same time, it was too unbelievable!
This kind of question was obviously a mid-range solution, but Wei Minghai had managed to solve it with his brain.
Even Zhang Ruiyun felt sad about this question.
Did he not care about his face?
If the teacher who set the question knew that you gave the answer within a minute, wouldn't he be so depressed that he would jump off the building?
Zhang Ruiyun's gaze subconsciously shifted to the dazzling parchment next to her.
"Sigh…"
He didn't want to watch Wei Minghai do the questions anymore. It was too depressing!
He then looked at the other students of Class 30. Fortunately, these people were not as terrifying as Wei Minghai, but their speed was not slow either.
Even the speed at which they calculated on the draft paper was not something that ordinary students could compare to.
Because this was the last exam venue, the busy students of Class 30 formed a sharp contrast with the other 20 students.
The contrast was too great!
Just as Zhang Ruiyun finished his round and returned to Wei Minghai's side, he had already completed the last question!
The script was still blank!
Wei Minghai once again refreshed Zhang Ruiyun's worldview!
“%￥#@￥￥%……！”
Zhang Ruiyun no longer knew what it felt like to be shocked. He was already numb!
There was not a single word on the parchment!
The test paper was even more concise and clear!
The last question:
The function f(x)= sin ^2xsin2x is known.
(1) We will discuss the monotonicity of f (x) in the interval (0, Pi).
(2) Proof:| f（x）|<3>(3)/8;
(3) Let n satisfy N*, prove: sin^2xsin^2(2x)sin^2(4x)…sin^2(2^n)x≤3^n/4^n。
With just one glance, Zhang Ruiyun was sure that this question was beyond the outline!
Furthermore, it was a serious violation!
"It's comparable to college entrance examination questions! Even the third-year exam papers would not dare to set such difficult questions!”
Zhang Ruiyun stood rooted to the ground, wondering if the exam team had gotten the questions wrong this time. Wei Minghai had already started answering the questions right under his nose.
Zhang Ruiyun was speechless.
F * ck, f * ck…
Zhang Ruiyun was roaring in his heart!
Hualala!
His scalp went numb. He immediately ran to Xu Heng's side and pulled him up.
"Teacher Xu! You do it! You do it! Come and see if the final question of Year Two Mathematics is beyond the curriculum!”
Zhang Ruiyun pulled Xu Heng to Wei Minghai's side.
Xu Heng took a closer look.
Wei Minghai thought about it and wrote:
Solution: (1) f (x)= sin ^2xsin2x = 2sin ^3xcosx
Therefore, f '(x)=…
……
Xu Heng sounded puzzled." Isn't Wei Minghai answering? How is it out of line?"
Zhang Ruiyun was speechless.
The next second, Zhang Ruiyun reacted." You're a language teacher! How could he know the progress of the math class? Phew…"
However, Xu Heng's next sentence was indeed," I also think this question is okay. It's not difficult at all!"”
Zhang Ruiyun staggered and almost lost her balance.
"Hu hu hu…"
His face was pale and he looked depressed as he stared at Xu Heng." You're a language teacher! Don't talk nonsense if you don't understand!"
Xu Heng smiled." Alright... but look at this. He Ruohua has also started to answer this question. Are you sure you didn't see wrongly? Are you sure it's beyond the scope?"
