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!

In order to be precise calculus must make infinite calculations. |

If we really speak of "real world curves", those curves are of a
brownian motion kind, nowhere differentiable and thus having no
tangent at any point. Calculus does not deal with that type of curves
anyway. Also what do you mean by "for all curves except defined
binomials"? |

Are you saying that calculus doesn't apply to changing real world
curves?
Only unchanging curves are nowhere differentiable pork. |

Review the limit concept and rethink the matter.

sorry I didn't realize I'm dealing with a clueless moron who keeps

Not true. If an exact solution can be derived, then only one calculation
is needed.
That' is the point exact solutions don't apply to real world problems.
Limits are approximations if not obviously guessable.
Exact solutions remain in the realm of binomials.

Dunning-Kruger effect (2000 Ig Nobel Prize): ignorance more
frequently begets confidence than does knowledge
1) Incompetent individuals tend to overestimate their own level of
skill.
2) Incompetent individuals fail to recognize genuine skill in
others.
3) Incompetent individuals fail to recognize the extremity of their
inadequacy.

Perhaps he is thinking of the quadratic curves: circle, ellipse,
parabola, and hyperbola, but mixed up "quadratic" with "binomial". |

Imaginary math needs to be confronted.
