[EDIT]: Thank you.
A 16-foot chord is inscribed on a circle with a radius of 767.81 feet. What is the altitude of the bisector of the chord to the circle? +2 if you can tell me how you come up with the answer.

I vote 16’, since the two extremes of the function are the points where x=r and thus the length of the chord equals r, and x=0 when the length of the chord equals 0.
I’m sure there’s calculus to prove me wrong, but FAKE NEWS.

- it explains it and provides a calculator - the bisector in your problem is the “sagitta”

As a Sagittarius I’m more than a little disappointed I didn’t know that term.

that’s the MathNerd ™ term, it’s pretty obscure

If the chord connects on either end to the circle, then you have a right triangle with hypotenuse with the same length as your radius. Using half the length of the chord (8') and R (767.81'), you can solve for the third leg using Pythagoreum’s theorem, which would be equal to (R - x).
So then (R)^2 = (8)^2 + (R-x)^2, solve for x.
x = .0417'
ed: damn too slow

Not all paths between two points are a straight line. In fact, to a very good approximation, none of them are. REAL NUMBERS

Id just draw it in CAD and measure it but that would mean id have to get up

I did that in Algebra once. Or was it Calculus? The math is familiar to me, but it's been many years. Thank you!

Was that a practical problem or an intellectual problem?

Practical. My BIL is building something for his job, probably a bridge, and he’ll be looking for how high the crest is from either side. Probably ordering some ready-made fabricated steel structure. But Oppo came through and showed me the geometry, and it’s really quite accessible.

Yes, an interesting notion how that word shows up in both contexts. I’ll ask Ttyymmnn about that one...
