Find the function of a curve

[Anonymous]

Hi There,

I've created a sketch in fusion 360 and want to find the function of the curve (ie. y = f(x)).

See the relevant sketch below.

Best Regards,

That looks like the arc of a circle in which case the general equation is:

y = ±√(r²-x²) where

r is the radius

In your case, r = 100 so

y = ±√(100²-x²)

At x=50

y = ±√(100²-50²)

y = ±√(10000-2500)

y = ±√(7500)

y ≈ ±86.6
