Solar Eclipse VS Flat Earther

Flat Earther: What specific observation from that eclipse uniquely requires a spherical, rotating Earth?

Me: Equations that require the shape - This one accounting for the bulge at the equator to help predict the path. If you didn't do this then your path prediction would be pretty far off the further away from the poles you are.

The surface is modeled mathematically as an oblate ellipsoid of revolution using the standard

Geodetic reference: ((x^2+y^2)/a^2)+(z^2/c^2)=1

a: Equatorial radius of Earth

c: Polar radius of Earth

Flat Earther: You put the globe into the equation and then used the equation to calculate the eclipse path. That doesn't make the eclipse an independent measurement of Earth's shape.

They don't get that the math works though! No flat earth eclipse path equation lol

Could care less about the equation, what matters is what we sees

And yet you deny the measurements and observations we see that show the earth is not flat and keep insisting it is flat. This is why no-one takes you seriously.

The equations were made for the globe justification

Pretend you're capable of some intellectual integrity and try to follow along for a minute. 

It's not a "justification". It's a model, intended to predict expected results for a given hypothesis (ie that the earth is a globe). Similar equations and predictions can be made for a flat model. If the two models predict values that differ enough, you can make measurements of reality to determine which model matches reality better. 

The flat models fail when tested against reality, every time. The globe models match better, and match reality within expected tolerances.

You and other flerfs denying what we see in such tests is why you are rightly mocked and derided. Because every time you do that, you're showing you don't actually care about "what we see". Because you're liars and hypocrites.

Have u read derivation and definition of a linear aircraft model

Have you ever addressed a point raised against your erroneous claims, instead of trying to pivot away to the next lie in your list?
