The love of functions and derivatives

This is the first reaction of the function.

But after a second, Function said to himself in his heart: Man, be more confident, remove the seeming——

He is looking at himself.

The second reaction of the function is—Made, the derivative is actually a bit handsome, and the damned man on the opposite side stepped on my aesthetic point perfectly.

Some strange feeling grew in his heart, Function immediately lowered his eyelids and said silently three times, "Are you GG or MM?", and finally suppressed his faint desire to be agitated.When he opened his eyes again, the derivative on the opposite side had already turned his gaze away.

It was late at six o'clock, and all the people came, and all the delicacies with good color, fragrance and taste were placed on the round table.There are not many mathematical definitions, and there are only two tables of people.As mentioned above, the relationship between functions and probability is pretty good, and functions naturally sit next to probability and chat about anything, but mainly for eating and drinking.

The function is delicious.

Opposite the three-dimensional geometry, the two women chatted happily. They have cooperated many times in the mathematics papers of the college entrance examination. Of course, if you ask any student who has experienced the third year of high school, you will also know that functions and solid geometry cooperation is indispensable.Because finding the maximum value of the normal vector is always indispensable to the analysis of the function.

Although solid geometry is a sub-question in the eyes of science students, it must be taken.But in the eyes of liberal arts students, this is still a very distinguishable topic.In addition, the small questions of three-dimensional geometry try to be used as the finale of choice or filling in the blanks, and the status of three-dimensional geometry is quite acceptable.

"Although it seems that the function has never taken the final exam, in fact, he takes it every year. After all, which math problem can completely remove the function?" Stereometry raised his glass and smiled, "This year is also a happy cooperation. !"

The space vector on the side also came to toast the function.

"Then I still want to thank the two beauties for their support." Function was a very polite and polite person, and he immediately bowed to touch their wine glasses with a smile.The three wine glasses collided with each other, making a crisp "ding" sound, and the wine shook in the glasses, causing ripples and microwaves——

"What are you looking at?" Sequence followed Derivative's line of sight, only to see people at the opposite table eating happily together, and toasting wine, then turned to look at Derivative, trying to find something on Derivative's face Clue.

The derivative had already lowered his head, and turned his attention to fiddle with the fish in the bowl.

"It's nothing."
