The love of functions and derivatives

As a first-level Weibo surfer, Function has deeply studied the misunderstanding of pictures in the "Zhengzhou Senior High School Backbone Teacher Training", not only learned, but also laughed——

In the eyes of the teacher, the expression/smile/indicates encouragement, and the expression/goodbye/indicates goodbye next time.

But in fact, in the eyes of students——

/Smile/ means to smile awkwardly and politely in front of a fool.

/Goodbye/ means that we can't chat with you anymore, so we can only smile and say get out of here.

Function was stunned for a moment, then fell into silence, thinking in his heart, this boss must be smiling on the surface, mmp in his heart, right?

The corners of the mouth of the yellow round face on the phone screen were bent into a perfect arc, and the two round eyes blinked and blinked, staring at himself outside the screen.Function trembled in fright, and the phone almost fell to the ground.

While not paying attention, Function glanced at the derivative beside him, and was caught.

function: why?Why do I get caught every time I peek at him?

Wait, why did I use the word "steal"? !

Derivative just pursed his lips and looked at himself, showing no signs of happiness or anger. The corners of his mouth and the meticulous collar all showed his master's restraint and conservatism.

The function suddenly realized, would he, don't know what /smile/ means in today's networked society, right?

Probably yes.

Thinking of this, I suddenly became enlightened, and suddenly laughed out of Lenovo's way of saying hello to "promoting traditional culture" on QQ.

"What are you laughing at?" Derivative asked.

The function feels unexplainable. If you explain to your head teacher why/smile/with a sarcastic meaning, your head teacher will think that this is as incomprehensible as you don't want to study hard to get a high score.

So the function says, "Nothing."

After singing K, it was late at night, and everyone was probably sent home. This banquet can be regarded as a successful conclusion.

This time Derivative showed his skills in KTV and surprised everyone. Of course, it is not just Function who made Derivative’s singing video. Derivative has never been very fond of running social software. He pays great attention to protecting his privacy, so there are few photos about Derivative on the Internet. photo.The few photos that belong to "hardly found" are group photos of professional smirks with other mathematics definitions and college entrance examination testers.

So I don't know who relied on his anonymity to do whatever he wanted, and uploaded the video to the group file of the high school mathematics textbook industry work group.

Solid geometry: worthy of being a boss!

Then the group suddenly fell silent, because another boss appeared, and she was Solid Geometry. At this time, Solid Geometry was stroking the hair that didn't exist next to her ears without moving her hands. She was holding a mobile phone in one hand, and was seriously admiring The derivative of sing.After the video ended, she asked the parametric equation of the little sister beside her, "What do you think?"

Parametric equations figured out the meaning of solid geometry, and there is always nothing wrong with exaggerated derivatives: "It sounds good."

Stereo Geometry smiled charmingly: "I think he matches me well."

Parametric Equations: "...yes. You have a real eye."

Stereo Geometry pressed the phone into a black screen, took a picture of his face with exquisite makeup, tidied up the hair that didn't exist, and let out a barbell-like chuckle.
