It's only valid if you are using the tangent

In reality you look down to the horion, that is not the tangent

No simple math will work. All your calculator needs is square root to use this.

It's simpler to use https://www.metabunk.org/curve/

No one should trust that. It is circular argument. You assume the earth is a ball. It shows a ball. If you want to believe the earth is a ball fine. But do not tell a Flat Earther to trust a ball earth site.

Everything in that calculator can be verified with trigonometry

I could care less where the horizon is. That is just a method of deception.

That midpoint. It is used to half the curve.

If you fail to understand that calcultor then I can't do more

Except why determine the midpoint. What it calls the horizon.

I call it the point of confusion.

Call it what you want, I don't care

Well there could be many things between you and what you look at. Hills or valleys. So that confusing midpoint is of no use. All I care about is how far down something should be at the distance I am looking from.

Did this man say we shouldn't use cosine because noone remembers it???

Since we seem to have lost the thread here. When you talk about angels living in the fourth dimension precisely what do you mean?

No I said that formula was most likely correct. Just harder to understand.

cosine isn't that hard to understand

Most flat earthers are also truthers. They do not trust globe earth sites or globe earth formulas.

there's a button

right on the calculator

That's the flatearthers loss

Well most of them. I have to change the one on Windows to get cos to appear.

However square root is always on it.

Steve you just set it to scientific

just download a better calculator

Its not at all difficult

Yes how I would and do change it when I want scientific.

U ok bud

`Yes how I would and do change it when I want scientific.`

Some on Android do not have that.

Focus Steve. angels. fourth dimension.

Every single phone calculator has it. You are just bad at looking.
Lets go to angels though.

4D

Yes I have to use those formulas when i want to compute things that require it.

Funny, my default android calculator has cosine

Well the old phones did not have it. Perhaps all new ones do.

@Logad not helping man

@Steve Angell Show me the old phone that doesn't

You keep backpedalling

Look it doesn't matter if his phone does or doesn't have that function

Anyway @Steve Angell you can use the scientific calculator to verify metabunk's calculator
