It's a 10-minute walk away, and it's a quick drive.

Four wheels, without traffic jams, are definitely much faster than two legs.

Qing Yun saw that there were still a few minutes before the bell rang, so he dragged Teacher Xiao Su who was about to get out of the car, and pulled it back with a long kiss.

Su Caiwei, who had just entered the period of love, was not reserved for anything, and when she thought of seeing him at night, she was even more obsessed with responding to his request.

It wasn't until he saw that there were already running students outside the window that Teacher Xiao Su hurriedly pushed the door and got out of the car and joined the running queue.

It is completely no different from a university campus 20 years later in the previous life.

At that time, in the morning, the front of the teaching building was also full of resentful running.

Emperor Yun looked at the scene in front of the teaching building at this time and smiled dumbly.

Then he fell into a long silence.

Once upon a time, he was also a member of this group of running troops, scolding and grinning, while his heart was towards the light.

In school, you can curse all kinds of injustices, all kinds of injustices, all kinds of darkness in the school......

However, when you are in society, you will understand that the reason why universities are called ivory towers is not for nothing.

Standing in society and scolding the school, either you haven't studied in college, or you're either stupid or sheer bad.

Of course, if you receive the money, others also have professional ethics.

There is no cleaner, purer, and better place in the world than a school.

After half a ring, and sighed lightly, Qingyun pressed the call button, and the vehicle slowly drove in the direction of the company against the light.

……

In a hurry, Su Caiwei still went up to the third floor before the bell rang.

Taking a few deep breaths, she gasped for breath as she sorted out her appearance in front of the crown mirror at the top of the staircase.

Teacher Xiao Su had to take care of the elegance before entering the classroom.

The students she had just met on the road, those curious and envious eyes, made her wake up.

Today......

Not the same.

There is a storm bigger than the previous day, waiting for her.

Compared with hiding and refusing to admit it some time ago, after the official announcement with the little man, she will inevitably have to face the public opinion and those meaningful eyes on campus.

Envious, jealous, disgusted, insensitive...... There will be any kind of look.

It's normal.

Living quietly can only show the failure of this life.

For Su Caiwei, these are not important at all.

The important thing is that from the next moment onwards she will face his woman directly.

The first to bear the brunt is the white and thin Chairman Chen who should be sitting in the classroom at this moment.

Looking at the crown mirror, Su Caiwei bit her lip, and wanted to untie the neckline of the high-necked long-sleeved dress on her body.

Once unraveled, at least two purple-red marks on her jade neck will inevitably be glimpsed.

Su Daji felt a little eager to try it in her heart.

Elegant!

Show it to Chen Yue?

Angry at this little who calls her 'Su Daji' behind her back!

However, in two breaths, Teacher Xiao Su put down his little hand that had already touched the button on the neckline, and turned around and walked towards the classroom with the bell.

What are you angry with a little girl?

Instead......

Su Caiwei also had to admit that Chen Yue's existence was too subtle.

The little man attaches great importance to Chen Yue.

has seen a lot of talented students on the college campus, and she has to admit that Chen Yue has a lot of brushes.

It's not that Chen Yue is irreplaceable.

Although Chen Yue is a little demonic, it is not so powerful that professional managers can't surpass it.

After turning her mind to the little villain, Su Caiwei could only helplessly say that indeed, Chen Yue's position must be sat by her own family.

Therefore, whether it is her or Qin Manman, when dealing with Chen Yue, they can only be co-opted in strict precautions.

However, what made Su Caiwei feel very uncomfortable was that when she walked into the classroom, in addition to the absence of the bastard in the classroom, Chen Yue's little girl was not there.

All right......

Although she can accept it in her heart.

After all, the little villain also said last night and this morning that the next few days will be the time of the Yanhuang Group's war, and Chen Yue, as his right-hand man, should follow him, which is also right-handed.

However, at this moment, Mr. Xiao Su is always a little unpleasant.

This is forcing class...... It's not interesting at all.

The clear eyes in the audience made her very helpless.

I was also caught in the door by the door.

That little bastard, how could he have so much free time to take high math lessons, let alone ......

Who's to say they could teach him?

She can't do it anyway.

However, the class without Qingyun making trouble still made Su Caiwei very comforting.

Last week, I quickly finished the preparatory knowledge of calculus such as 'sets, functions, and limits', and today is actually the first lesson of calculus.

Derivatives and Differentiation

The students in the audience are actually the epitome of the campus, and the eyes cast at her at this time also have various meanings.

Of course, it was more like eating melons and watching a play, and the buzzing whispers under the podium were like a swarm of mosquitoes.

For a while, Su Daji wanted to play 'flipped classroom' angrily.

But in an instant, she smiled in her heart and began to talk about the lecture seriously.

The reason why high numbers are called high numbers is that there are many people hanging on the tree on the top of the mountain.

If you like to listen or not, anyway, at the end of the term, she won't catch people.

'That's fate!' ’

This sentence will be the last lesson she left for the students in this class as a math teacher.

Life paths are different, each with its own destiny.

Su Caiwei has already decided that she will not attend this class after taking this class this semester.

There's no need for it.

She made up her mind to graduate early with her Ph.D., and then quickly mix her qualifications to become a researcher and then transfer to a professor.

What happened on the lawn in front of her house this morning made her truly realize what her greatest strength was.

If she wants her mother's family to support her, she must be the most favored and capable daughter in her mother's family.

The customs of this society allow Qin Manman to coerce a female doctoral student of Fudan University, but she can't coerce a female professor and academician of Fudan University!

"Differentiation is the geometric meaning of the derivative, and it is also the increment of the value of the function with the change of the independent variable, and this increment is the differentiation.

To put it simply, you can think of differentiation as an approximation of the increase in the value of a function. ”

Su Caiwei explained, while picking up chalk and brushing on the blackboard to write.

The students who were still guessing what would happen between Teacher Xiao Su and Qin Manman today were distressed at this time.

Teacher Xiao Su obviously came to class today with a little emotion, and the speed of the lecture is much faster than before.

Although the students sitting in the audience were Fudan students, they were not from the mathematics department after all.

The fight between the two tigresses, don't take us with you!

The scum can't keep up!

When talking about the derivative of composite functions, Su Caiwei suddenly paused, looked out the window, and smiled unconsciously.

The audience was quickly taking notes, and the students who were running wildly on the mountains following her train of thought looked at each other.

This is......

Desertion?

Or do you miss your lover?

Although, Mr. Xiao Su, who has always been a cold fairy, looks so good when she smiles!

But......

Today's Teacher Xiao Su is obviously abnormal!

This beautiful smile made them feel terrible!

Su Caiwei didn't actually think about anything strange.

She just thought of the 'love brain' language that the little villain had spoken in his first high math class.

Su Caiwei tilted her head and thought about it, then turned her head and smiled slyly at the students in the audience,

"The derivative of complex functions usually requires a step-by-step derivative from the outside to the inside, and the final result will be obtained by multiplying multiple layers.

What I mean by this is that the derivative of the composite function is like a love, in the process of getting to know each other from the outside in, step by step, and finally accept it all, so that there is a correct result.

Got it? ”

With that, she couldn't help but laugh to herself.

The students in the audience looked at the counselor who forcibly sprinkled dog food on the podium with a depressed expression.

This Xiao Su teacher doesn't talk about martial arts!

Except for a few in the classroom who are in high school romances, the others are pure-blooded single dogs.

This wave of dog food, especially echoed last week's Xiaoqing, and directly hit them with a boomerang that made them vomit blood and die.

But......

Frankly speaking, this paragraph that Teacher Xiao Su said made the whole class sober up.

It's not a sober feeling about love.

It's the real clarity of the mind.

No way, eight in the morning......

Teacher Xiao Su pulled it too fast just now, making their brains confused after half an hour of high-speed operation.

Now this dog food is too inhumane to feed, but it is easy for them to change their brains.

At this time, Su Caiwei, who was drinking water, raised her eyes to look at the mental state of the students in the classroom, and suddenly understood why even in the university, the teacher needs to spend a while bragging in class.

In order to impress the students on the knowledge points in class, they must talk for a while, and make everyone feel drowsy, but most of the students like this way very much.

She simply stopped, and she did speak too fast just now, after all, the students sitting here are different from the students of the Math Academy.

Economics is a liberal arts and sciences discipline, and seriously speaking, the overall level of mathematics is indeed a grade behind the Academy.

"If you have any questions, it's time to ask questions."

But......

She forgot one thing.

Those who love to ask questions are good students.

And good students, the questions they ask usually do not represent the level and teaching progress of the class.

Although it is true that the overall level of mathematics in the Department of Economics is not as good as that of the School of Mathematics, it is unfortunate that many of the students in this class are guaranteed students, and many of them are competition students.

The much-criticized rule that students can only choose majors related to competition subjects was finally abolished this year.

As a result, a discipline like economics, which is the king of science, has become the favorite of competition students.

Therefore, some of the competition students sitting in this classroom are actually no worse than those in the first semester of their freshman year.

Even many people in this crowd, like Qingyun, finished teaching themselves high math as early as high school.

The questions asked at this moment are all specious knowledge points that they did not understand when they were studying on their own.

As a result, Su Caiwei was shocked to find that the scope of these questions covered the entire calculus textbook.

After Teacher Xiao Su answered them one by one, he sighed in his heart.

She knew that when she was explaining to this group of problem children, the eyes of others were actually blank.

It's not too common for students to have different learning paces in college.

At this time, she had to think of a hateful figure again.

When some people enter university, it is really a blank slate, while some people enter university, and the paper is already thousands of miles away.

Therefore, when this group of people sat together, in addition to lamenting that the difference between people is too great, it can only make this group of blank papers lose the courage to catch up from the beginning.

After answering an integral median theorem, Su Caiwei turned around and drew a coordinate system on the blackboard, and then drew a graph.

Then she turned to the group of students with dull eyes and said, "The figure I'm drawing now is a geometric representation of the integral of sinx from 0 to π/2, and that's what you'll learn later." ”

Under everyone's uncertain expressions, Su Caiwei smiled, "I don't want to pour chicken soup on you and say that everyone can succeed, it's impossible."

Some people have the talent to succeed in a lifetime, and this society is so cruel.

But you ...... The fact that you are sitting here, sitting in a classroom at Fudan University, speaks volumes about your talent for success.

It's just that this success is big or small, and your success may be just a small success in the eyes of others, but isn't it a success?

There is no need to envy others, in my opinion, seeking points is like our life, and every point is our own desperate growth.

Everyone is sinx, as long as you continue to ask, this point will eventually accumulate and complete, and reach your own life highlights. ”

She was met with a few seconds of silence.

At this time, Su Caiwei was a little remorseful, she didn't have the ability of Qingyun's incendiary speech.

A word of encouragement, but she said it dryly, it is difficult to be convincing.

But she didn't take it to heart, a short paragraph could not inspire an adult's fighting spirit, let alone bring them a light to guide them forward.

Just as she was about to laugh at herself, there was a round of applause in the classroom.

Indeed, as she thought, her words were not enough to make the group of college students feel passionate.

A small success, is it a success?

Since success is divided into small and small, why is small success considered success?

It's just comforting words.

However, it is this kind of comforting words that makes her sincerity and kindness recognized and respected by them.

Although they have not been enrolled for a long time, they also know that Fudan University is rich in refined egoists.

Why is the involution serious?

Because self-interest prevails.

How can a teacher be self-interested?

Pour limited resources into outstanding students.

How can students be self-interested?

Become a good student to grab limited resources.

Therefore, in this campus, this kind of argument of Mr. Xiao Su is really rare.

I dare not say respect, but I can still say thank you.

But at this time, Su Caiwei was very uncomfortable.

She felt ...... She didn't make sense of this truth, but the smiles on the students' faces made her embarrassed to continue to talk about the big truths of life.

Well, this kind of atmosphere, she is not used to.

Pointing to the multivariate function just mentioned on the blackboard, she smiled at the boys, "In multivariate function differentiation, when a function is biased towards an independent variable, the other independent variables are treated as constants.

I mean, when a girl likes a guy, even if she has a lot of good people around her, that boy is still the most special one for her, she only sees him, and only prefers him.

Got it? ”

Teacher Xiao Su said that compared to reasoning, it is more fun to stuff dog food for purebred single dogs.
