Jiang Han wasn't going to explain anything.

Since the roommates think so, they are tired and panicked to explain.

"Okay, sleep, get up early tomorrow, I heard that the counselor will have a class meeting tomorrow. ”

Early the next morning.

Jiang Han came to the class surrounded by three roommates who had gradually become acquainted, and also met his dear Supervisor Chen. Director Chen doesn't seem to be very old, she is a beautiful big sister, and she should have just graduated.

After talking about the precautions for new students and military training, the first class meeting of the school year was dispersed.

The rest of the day is spent familiarizing new students with the campus.

Some went to the cafeteria in groups, some went back to the dormitory, and Jiang Han said goodbye to his roommates and came to the library alone. The number of people in the library today is significantly larger than on the first day of school.

Jiang Han continued to take out the "Mathematical Analysis New Lecture Zhang Zhusheng Edition" and read it carefully, looking at it and gradually becoming obsessed, when he found that the solution of a problem was not the same as what he thought, he took a pen and a piece of scratch paper and began to calculate.

A piece of A4 paper was written in less than half an hour.

And the title is gradually showing its true face.

"That, classmate......"

Suddenly, a voice came.

Jiang Han raised his head and saw a beautiful girl in front of him, oh no, a beautiful girl with a bookish air was looking at him.

"Are you?" Jiang Han was sure he didn't know the person in front of him.

The beautiful girl pointed to her hand, and said, "This is my ......."

Jiang Han looked down and saw that he was holding a pink pen in his hand that he had taken out of nowhere, looking particularly girlish.

"I'm sorry!"

Jiang Han hurriedly handed it over in his hand, and said slightly apologetically: "I was in a hurry, but I didn't expect to take your pen." ”

"It's okay, it's okay. The beautiful woman in front of her waved her hand, and then handed over a piece of straw paper from front of her, with a question written on it, and asked a little embarrassedly: "Do you know how to teach this topic?"

She saw that the classmate in front of her was writing the math problem on the papyrus, and she couldn't even understand it.

I think I should have a lot of attainments in mathematics.

So she planned to take the question and prepare to ask people.

used other people's paper and pen, and Jiang Han was embarrassed to refuse others.

"Okay, I'll take a look at the title. ”

"Thank you. Whispering thank you, the girl lightly lifted the chair, sat next to Jiang Han, and intimately presented paper and pen.

Jiang Han was not polite, took the paper and pen, and looked at the topic.

Try to find the positive numbers a and b so that the equation (x→0) lim1/(x-bsi

x) ∫t²/√(a+t²)dt=1 is true. (∫ is marked with x in the upper corner and 0 in the lower corner)

Advanced algebra!

Is it hard?

Jiang Han's pen tip moved slightly, and he drew two casually on the scratch paper, and solved the problem in less than a minute, "It's solved." ”

"This ...... Is this the solution?" Zhou Qinqin looked at Jiang Han in disbelief.

Just draw a random picture on scratch paper and solve it?

Jiang Han said: "It's not difficult. ”

As he spoke, he began to write down detailed steps on scratch paper.

"This problem is a typical 0/0 type infinitive, direct Lobida rule, the first step is to split the integral, this is not difficult, →right?

x)=0, you can get b=1, and then bring back the original formula, you can solve a=4, you look at the answer, I solved it right, right?"

Zhou Qinqin looked at the scratch paper in a daze, and only felt that the guy in front of him was solving the problem very fast, faster than the speed of his own lectures.

Especially when the last two answers were written, her mind was still stuck in the step of solving the integral.

With a skeptical feeling, she opened the answer, and her glasses instantly widened.

That's the answer!

Noticing the expression of the beautiful girl in front of him, Jiang Han smiled a little proudly, "It's just a very simple application of the law of Lopida, and the calculation itself is not difficult, so this is the first year of college, right? You should be a sophomore, right?"

The person in front of him said that he couldn't say anything like a freshman.

After all, I'm only a freshman in this year, and if it's a sophomore, then this beautiful girl's grades are really a bit worrying.

Feeling Jiang Han's gaze, Zhou Qinqin blushed and whispered, "My ...... for the graduate school entrance examination"

As soon as she said that, her face turned even redder.

It's not shy, it's angry!

It's infuriating!

Isn't it just solving a math problem?

What to show?

As a graduate school entrance examination party, I have just started to review, is there any problem with returning the knowledge I have learned before to the teacher?

Won't I remember if I watch it twice more!?

"Ugh. Jiang Han was a little embarrassed, and he didn't know what to say, so he was silent for a while, and decided to comfort some of the senior sisters in front of him: "Actually, this question is also a bit difficult, and I have a hard time doing it......"

“？？？”

Zhou Qinqin's eyes widened, and it took less than a minute to solve it, which is also called labor?

Are you talking about human words?

Are you comforting me?

How do I feel like you're stimulating me?

Zhou Qinqin moved the bench back to its original position with some anger, and angrily took the straw paper in her hand and put it in front of her.

You deserve to be in the library alone!

Someone like you must not have a girlfriend, right?

You deserve to be single!

Feeling that Zhou Qinqin's mood seemed to be a little strange, Jiang Han was a little confused, so he scratched his head and thought about it for a long time, but he still didn't understand where he offended her.

Forget it, no matter.

Although you do look a little bit good.

But...... Can a girl have an important study?

Interpersonal relationship?

Friendship between men and women?

Oh, sorry, Xueba really doesn't need those things!

Jiang Han looked at the idle task on the attribute panel that was about to reach ten hours, and saw that it would take a little more effort to complete it, and he had to hurry up, and he was about to continue reading.

Unexpectedly, a message came from the phone at this time.

I took a casual look.

It was sent by the counselor.

He felt strange in his heart, so he opened the message and looked at it, which probably meant that he asked himself to find Director Wu of the Department of Mathematics as soon as possible.

Jiang Han thought to himself, so he quickly edited a text message and asked: Director Chen, do you want to bring some gifts?

Director Chen: Those who engage in learning don't need these gorgeous and fancy!

OK！

Jiang Han looked at the time and decided to go over and take a look now.

So he got up and packed his things and prepared to leave.

Zhou Qinqin, who was sitting on the side, noticed Jiang Han's movements, and thought that he was going to come over to apologize to himself, but who knew that Jiang Han turned right along the corridor...... Let's go?

Zhou Qinqin suddenly fell into deep thought.

Does he really look down on me?

Is my math really that bad?

......

......

Jiang Han found a postgraduate entrance examination classroom.

At this time, Director Wu was answering questions to the students who were going to take the postgraduate entrance examination in the postgraduate entrance examination classroom.

Qingda is still very humane in this regard, and has set up a separate postgraduate entrance examination classroom for many students who want to take the postgraduate examination, and arranges a Q&A teacher every week.

If you have any questions that you don't know, you can ask the teacher on the day of the Q&A.

Jiang Han walked to the door of the postgraduate entrance examination classroom and saw an old man from the Mediterranean Sea at a glance.

Alas, this old man is somewhat familiar?
