In order to derive a tangent line on a changing curve you must do
calculus. You must pick two points to get the the tangent line and get
the same slope. Calculus is just an estimation. You cannot become
infinitely accurate because you cannot make infinite calculations. You
could make a million!


The tangent line is an infinitely small cord.

Since a line is infinitely long, how can it be infinitely small?

Also, do you mean chord, or are you talking about a line made of
twisted fibers or threads, a unit of amount of wood cut for burning, a
light insulated conductor for household use, a cut pile fabric with
vertical ribs, or something else?

That is the Continuum Hypothesis: there is infinite amount of the
infinitely small.
