Function

Real life.

I think in mathematical equations-
Derivatives unravel in my skull.
Vectors determine my direction-
"A woman walks due west on the deck of a ship..."

Is there an algorithm that will tell me if I'm real?
What is the integral of your smile, your voice?
What is the limit of my functional heart
As its contents approach infinity?

That sideways eight that I cannot imagine;
A concept beyond my mind's capabilities.
What is my domain between zero and two pi?
We are orthogonal lines, you and I.

Am I a real, rational number?
I'm a girl made up of integers.
My thoughts are oscillating functions;
My limit does not exist.
