1, the bubble-like love drama, if expressed in mathematical language, is mostly just a few randomly selected samples, and then used to arrange and combine, and then analyze the probability of a certain situation.

4. An equation without roots does not necessarily have roots, but may only have imaginary roots, which means that something new has come into being, which means that we can predict the future and fill in the gaps.

5. The sum of squares of sin and cos is 1, SIN is divided by cos to get tan, and the range of tan is from positive infinity to negative infinity, which can be understood as "the affection between two people is infinite and immeasurable.
