Calculus in Tanka

A limit can be 
Calculated, true; but the 
Calculations can 
Never approach the limit---
It's where infinities touch.

A sine function works
On the logic of Pi. So,
The sine function will
Work off approximations
Of circles' geometry.

Zeno's Paradox
Is calculus. The leaps are
The calculations
While the limit is the place
Where man and reptile meet.
