2. The relationship between people is like a rational point on the number axis. They can be close to each other, but there is always a gap between them.
People are not lonely, just like a rational point on the number axis, you can find your partner in any small neighborhood.
4. People are lonely again, just like after marking the irrational points on the whole number axis, people can't be seen.
The relationship between man and fate is like the relationship between F(x)=x and G(x)=x squared. At first you thought that fate was your equivalent infinitesimal. As you get older, you find that all your efforts can't keep up with fate. This is why the catchphrase "Everything is a cloud!" .
6. The zero-point existence theorem shows that even if you stand on the opposite side of him, as long as your hearts are continuous, you can find your equilibrium point.
7. Life is a series, and ideals are the values you are eager to converge on. Don't miss every opportunity, otherwise the series will be missed; Don't care too much, because limited life can't describe infinite series, and convergence is just a dream. Therefore, we should manage every day in a down-to-earth manner!
8. The finite covering theorem shows that if something is not impossible, it can be realized with limited time and energy.
9. Pain is endless. As time goes on, it can become smaller and smaller, but it can't die.
10. The last point in the interval set is insignificant in the whole interval, but it must exist and be unforgettable.
1 1. How many ideals and commitments have been unrecognizable or even gone after several times of seeking advice? Is there an oath that any derivative of f(x) will remain unchanged? There is the x power of e, and it is strictly monotonic increasing, with no inflection point and no stagnation point. Even if it is outside the cloud nine, it is also concave, so modesty is necessary.
12. Happiness is integrable, and limited discontinuity does not affect its accumulation. So we should forget a little unhappy and face life optimistically!
13. The world is material and the age is increasing. Time is the positive axis, and life is polar coordinates. Life is limited, life has an inflection point, and everyone can have a "bright spot".
14. Lovers are an asymptotic time series, and home is the same gathering point you have. Maternal love is a divergent positive series, and the longer it takes, the more it will be.
15. The real brother is your asymptote. The longer you stay, the closer you get.
16. Life journey is a uniformly continuous function on the interval [0, n]. Since it starts from 0 and returns to 0, it obviously satisfies Rolle's theorem.
17. The mean value theorem tells people that the richest and poorest people in the world are the upper and lower limits of personal wealth, and you are only one of them at most, so please don't be happy or sad. Just be happy every day.
18. Everyone's marriage is like a series. The series of happiness (convergence) is similar, but the series of misfortune (divergence) is different.
19. The general term of convergence series is infinitesimal, which tells people that to have a happy marriage, we must manage every microscopic term well, so there is a proposition: "Love is great!" If it is a theorem, please give a strict proof. If you want to say it is wrong, please give a counterexample.
20. The single aristocrat is a univariate function, the newly married family is a bivariate function, and the next generation constitutes a multivariate function. Of course, having two incomes without children is also diverse.
