"There are thousands of triangles in the world, I will only be your only hypotenuse"
"No need to guess the relationship, the Pythagorean Theorem has locked us up"
"In your name, enter my heart"
It turns out that the most touching relationship in mathematics is
It's a string and a tilt, and they depend on each other year after year.
Even if there are thousands of function changes, my heart will always be tilted towards you.
You come and go, I always lean;
You hide the endless cycles and romance, and I keep the constant inclination and firmness.
You go round and round, gently,
I take one step at a time, just for you.
Every inch of your fluctuation,
They all hit my softest heartstrings.
Others calculate functions and find limits,
I only count how obvious my liking for you is.
My inclination remains unchanged,
Your tenderness is infinite,
All the formulas in the world,
None of it is as sweet as our perfect match.
You are responsible for the gentle ups and downs,
I am responsible for running firmly,
This is called our function,
The value range is all happiness,
The domain is forever.
