A zero vector can have many directions, but only one length. Just like me, I can have many friends, but there is only one you that deserves my love.

Life can be sweet or bitter, but it won't be boring without you. Just like the denominator, it can be long or negative, but it can't be meaningless, and its value is zero.

With you, my world is infinite, because no real number can express my love for you.

My feelings for you are like an exponential function based on the natural index e, no matter how many derivative storms there are, they will remain unchanged and the true feelings will last forever.

No matter what kind of random variables are in front of us, no matter how much variance there is in the future, I believe that after the trough, will the peak be far behind?

If I am a function, then you are the domain. Without you, I have no meaning to exist.

If you are a hyperbola, then I am your asymptote. Although we will never meet, I will always accompany you silently. ?

There are not only mathematical formulas on the draft paper, but also the names of people who are very important to me.

There is a saying in mathematics that a wrong process is a wrong one.
