What romantic mathematical formulas do science students have?

The romance of science students-the mathematical formula is as follows:

1, you are like ∫f(x')dx, I am like f(x), I am just one of your choices, and you are my only answer.

2. Sometimes I really hope that your eyes and mine will always be a bunch of opposite vectors.

I will be very lost without you, because the probability of meeting and liking someone again is the probability product of countless small events.

4. I still like you, like the square of sin plus the square of cos, which is consistent.

We are like two concentric circles. Whether the radius is the same or not, our hearts will always be together.

6. I miss you like an infinite decimal, over and over again, never ending.

7. If one day, we are attacked in another world and divided into two ends of a straight line, I will definitely cross the barrier of time and space, draw a common vertical line and run towards you.

8. If you accidentally go to the two ends of the number axis, the positive and negative are infinite, and it is difficult to meet again. It doesn't matter. All I ask is the countdown, and we can be together forever.
