Chapter 296 (2/2)
As for now Five minutes is enough.
Cheng Nuo wrote on the answer sheet without using the draft paper: ”a is a nilpotent matrix, so there is a ^ n = 0, remember that f (x) = (1-x) ^ α, when J > k, record Therefore, the necessary and sufficient condition for the existence of integral ∫ g (ij) (x) DX is a ^ 3 = 0.]
Cheng Nuo raised his wrist and looked at the time, which was no more than five minutes.
Cheng Nuo originally planned to hand in the paper like this, but after pondering for a few seconds, he picked up the carbon pen and wrote in the blank space of the last big question:
[solution II: directly express g (x) with Jordan Standard form, so we can get 】
……
Outside the examination room, Professor Liu and Professor Lu are both looking forward to it.
At present, the examination time has passed 30 minutes. Based on their experience in previous years, more than 10 minutes later, some candidates began to hand in their papers and leave.
”Lao Lu, don't be so nervous. Anyway, the result is doomed. Just enjoy the process.” Professor Liu laughs at Professor Lu's slightly white fingers, holding the armrest tightly.
Professor Lu white sitting on the side of Professor Liu one eye, ”don't be too proud, who loses who wins, the result is unknown.”
Professor Liu said with a faint smile, ”but I don't think so. In fact...”Half way through, Professor Liu stopped abruptly.
Because, in his line of sight, has seen a figure from the examination room slowly out.
So fast! It's just over 30 minutes, and it's done.
Are those boys suddenly acting extraordinary today?
Professor Liu's thoughts were flying in his mind, and he fixed his eyes on the figure. He wanted to see which one of the students was his favorite.
Xu Jie? Chengfei? Or Zhang Heng?
However When his eyes fell on the face of the figure.
At first sight, I don't know!
Second eye, or do not know!
Professor Liu began to panic. Is
He glanced at Professor Lu beside him, and found that Professor Lu did not show any expression of joy. When he sat there, he was slightly relieved.
It seems that this is not a student of Tsinghua University.
I didn't expect to let a student from another school get the top prize this year. However, it is not Tsinghua next door, which is the best news for Professor Liu.
However, when Professor Liu was congratulating himself, he saw the first student who came out of the examination room and went straight to Professor Lu.
Professor Lu's flustered look had long since disappeared. He nodded softly, ”Cheng Nuo, how difficult is the test this year?”
Cheng Nuo shrugged, ”it's OK, just so. It's similar to the difficulty of training
”Not bad.” Professor Lu clapped Cheng Nuo on the shoulder, pointed to Professor Liu, and said, ”this is Professor Liu Changfeng of the University of mathematics, an expert in the field of number theory.”
”Just now, Professor Liu and I had a good talk, and had voluntarily given a project to Tsinghua Institute of mathematics. This is Professor Liu's generous acceptance of our Tsinghua Institute of mathematics. ”
Cheng Nuo looked to Professor Liu, ”thank you, Professor Liu.”
Professor Liu: MMP
PS1: Happy Dragon Boat Festival!!
PS2: I'd like to advise you not to gamble any more. This world cup is poisonous! Apart from the fact that China didn't go to the world cup, everything else was normal.
