The love of functions and derivatives

Today, too, is a fairly ordinary and mundane day for functions.It was so common that he once again forgot to bring water when he went downstairs in the morning, and he was very thirsty, so he had to squeeze out some time from the urgent working hours and go to the convenience store in the community to buy a bottle of C'estbon.The only thing that was a little different was that the cashier boy in the convenience store actually wore a black peaked cap.Function silently thought, wearing a hat in a room without air conditioning in summer is a werewolf.

In the summer of August, the weather is hot and dry, the cicadas sing constantly, and the hot temperature of the sun is transmitted through the soles of the shoes. People who walk feel that they are enduring inhuman torture without taking a step.But these tortures have nothing to do with function, because after buying water, he got into his car, turned on the air conditioner to the right temperature, and drove to work.

Today's tasks are also quite ordinary tasks. As usual, the function sorted out the topics and related knowledge points, printed them out, and then neatly stapled them together.The function is the same as before, he knocked on the door of the derivative office, and then pushed the door in——

But found that the three-dimensional geometry is also in the derivative office, leaning softly and pretentiously next to the air conditioner, as if showing the curve of his body to the other party.Three-dimensional geometry is called this, unconsciously showing your beautiful side to the other party, and making the other party attracted by it.

Function felt that the scene was a bit awkward, and was secretly surprised in his heart. The mathematical definition of three-dimensional geometry and derivatives, which are completely irreconcilable, cannot be put together to formulate a problem. I am afraid that it is not just a discussion of work in an office, right?

Tsk tsk tsk, the derivative is not shallow.

"is it him?"

Function heard Stereo Geometry ask loudly, his tone was a little tense and exasperated.

It seems that things are not that simple. At this time, Function just wants to step aside, take out the snacks he left in the office, and then watch a movie while eating. Level people questioned, this kind of gossip, who is not curious?

But the beautiful fantasy of the function was quickly shattered by the operations of the two parties.Because the function didn't notice, when the three-dimensional geometry asked, she glanced at herself, and then she focused her gaze on the derivative's face, trying not to let go of any subtle expressions on the derivative's face.

Derivative sits on a rotating chair and can change direction at will, so he rubbed his shoes on the ground, turned himself directly opposite the function, and took a deep look at the function. Emotions.

function:? ? ?what's going on?Why are you looking at me?I'm just a melon eater.

Function faintly feels that the flames of war are going to burn on him, but since he doesn't know the situation, he can't say anything, so he can only wait and see.

In the silent office, the three people were almost still like statues, and only the hum of the air conditioner could be heard, which made people feel a little numb.The derivative looked at the function for ten seconds.

That is definitely a long full ten seconds, Function thought, there is no way I could count it wrong.

Because he heard his heart beat ten times.
