It was close to 10 o'clock in the evening, Ge Yao'er returned to the dormitory to wash, and there were two simple bottles of toner on the table.

There is a toner here, and next to it is the real question written by Wen Xiaoguang himself, some of which have very subjective answers to short-answer questions, this thing can very much see the skills of the book writer.

Although undergraduates claim to be higher education,

But there is no understanding of the frontiers of this discipline.

Lin Beibei also had the same rhythm as her, but she was ready to climb into bed at this time, twisted her waist before going to bed, and it was very uncomfortable to study to sit for a day.

"Yao'er baby, will you go to bed with me?" Lin Bei folded his hands on his hips and leaned upside down.

"Right now, I'm too tired today," Ge Yao'er shook her neck.

"Let's go,. Lin Bei saw that she was very careful about placing the materials, and asked, "Did the doctor reply to your message?"

The girl took out Nokia and opened the mobile phone QQ to see that there was no yet.

"No, maybe he's busy, let's see on the weekend. ”

Before going to bed, she also brought a collection of real questions, although she was very tired, she didn't dare to go to bed so early, and if she didn't learn 12 o'clock, what would she talk about taking the Jiangnan Institute of Technology?

The other roommates also asked, "What doctor?"

Lin Bei replied in an exaggerated tone: "It's the one who sells her real question book, that doctor is very powerful, which page in a book has which question, you can remember it, and when it comes to professionalism, Yao'er and I can't understand it at all, the key is that his handwriting is very special and beautiful." ”

"You're talking about people?"

Limbey: "I feel mysterious. ”

"I'll see what the handwriting looks like. ”

Lin Bei hurriedly took it from Ge Yao'er's hand and handed it to the top bunk on the other side, and the eldest girl opened it and exclaimed, "Damn, a man writes such beautiful words?"

Ge Yao'er's eyebrows flashed slightly, "It doesn't have to be a man, it's just Dr. Wen, and the gender can be male or female, right?"

Lin Bei also nodded, thinking about it carefully, it is really difficult to distinguish the gender of this year, without taking off his pants.

"Alright, bring it over. Ge Yao'er stretched out her hand.

The girl was a little reluctant, "It's good if it's a man, the words are like people, they must be very handsome." ”

Ge Yao'er couldn't listen to her ears, the heavy pressure of preparing for the exam was frightened, and the love of children couldn't attract her attention at all.

Besides, the graduation of the senior year is imminent, but anyone who can worry about their future has no intention of engaging in such bullshit at this time.

Ge Yao'er was sad all day long, and the best thing for her at this time was not to give her a handsome guy, but to put Dr. Wen in front of her to tutor her, and whip him without serious lectures.

The lights went out in the dormitory, and she and Lin Bei were the ones who were admitted to graduate school, even if they were studying, they used desk lamps on the bed, and they couldn't turn on the headlights to affect other people's rest.

Time slipped by second by second,

Ge Yao'er leaned half-on the head of the bed, reciting the principles and scope of application of several commonly used models through the lamp.

Several other people are actually touching their mobile phones and doing basic actions before going to bed.

At a certain moment, Nokia suddenly 'dripped', Ge Yao'er probably thought that someone was harassing her, and it took more than ten minutes to watch,

When I picked it up, it turned out to be Dr. Wen's reply!

Although the tone is a little cold: what's the matter?

But she was instantly excited!

A carp jumped up after shutting up, and Lin Bei, who was even on the bed, screamed, ", Yao'er, you almost shook off my aunt's towel, what are you doing, training your waist?"

It's a pity that Yao'er ignored her. She picked up her book and phone and got out of bed.

The other roommates were stunned by this movement, "What's wrong Yao'er?"

Ge Yao'er replied while turning on the computer, "It's not much, it's not much, it's Dr. Wen online, you can rest." ”

Lin Beibei was lying on his back on the bed, very speechless, thinking it was a big deal, and complained: "What are you excited about, if you want me to say that Dr. Wen must be a woman, which man writes such a regular word?"

Wen Xiaoguang: ???

Ge Yao'er read that Dr. Wen's message had been sent for fifteen minutes, and she was a little annoyed, so she hurriedly typed.

Ge: Dr. Wen, are you still there?

In Wen Xiaoxiao's bedroom, Wen Xiaoguang was copying the courier information of fourteen orders in front of the computer, and it was almost there.

There are also other people's inquiries on QQ, and he replies to them one by one.

Ge Yao'er was not the only one who asked questions.

Wen: It's still there, what's the matter?

Smack! Ge Yao'er clapped her hands! Fortunately, the person didn't leave.

A few days ago, Dr. Wen gave her so many things, she was really a little out of breath, there were four people in the dormitory, her parents at home, who could she say about these pressures?

I can't sleep in the middle of the night, even if I tell others, what can others do?

She didn't have much else to do except find that Dr. Wen on QQ.

This is the only person who can understand and help her.

Ge Yao'er sent a message: Dr. Wen, excuse me, are you free now, I have some questions I want to ask you when I am reviewing.

Of course, Wen Xiaoguang knew about these things, and there was nothing else that the two of them could say.

Wen: You say.

Ge Yao'er actually has a lot of questions, and she doesn't know where to start, so she can only pick the calculation questions that she is not good at and have relatively high scores.

Ge: Regarding the optimization part, I read a question yesterday. Proof that if the function F(X) is strictly convex, then its local minimum point is the global minimum point, and the global minimum point is unique.

Wen Xiaoguang put down the pen, he actually didn't know why this question was difficult. The questions in this part are quite basic, and you can do it casually.

These mental activities do not need to be told to him.

It's just that this kind of letter is a bit troublesome to type.

He replied simply: use the method of counter-evidence.

Ge Yao'er waited for a long time,,,

Ge: And then?

Wen: "......"

Forget it, type two lines, type it down to form a word, and save other people to ask the same question in the future.

Since he came out to sell and took the money, he had to do something, which is the basic principle.

Wen: First of all, assume that x^* is the local minimum point of F(X), and let x^' not be the global minimum point,

Ge: yes.

Wen: So ∃x',f(x')

Ge Yao'er is still serious about learning, and she also forces herself to think, instead of waiting for everything.

In fact, Wen Xiaoguang wrote that step, and people who are not too stupid know what to do next.

After about two minutes,

Ge Yao'er typed: Understood, thank you, Dr. Wen.

This is a proof question, there is no answer, it is reasonable step by step, and he does not need to check.

Wen: Anything else?

Of course, he himself may not know that he is looking forward to the cosmic desolation from the origin of life.

This night, until Lin Bei got up to pee, Ge Yao'er was still in front of the computer, and the time was more than half past 12.

Bei Bei came over and touched her head, "Yao'er, are you crazy?"

Ge Yao'er has a happiness that is usually difficult to see.

"I'm not crazy, I'm studying. ”

Lin Bei thought about the time, and really wanted to shout, most of the night is so energetic to study, you should be sober, two hours ago I said that I was very tired of the dog!

And Ge Yao'er hugged Lin Bei's waist, full of excitement, "Let me tell you Beibei, Dr. Wen is really omnipotent!"

Limbey: Kid, are you stupid?
