Circle Center Coordinate from D and E Calculator
Circle Center Coordinate from D and E Calculator — change the supplied values to calculate circle center coordinate from d and e.
Coefficient D/E units are coordinate units. This reports only the formal center; existence or radius of a real circle is not certified. Coordinate 0=x, 1=y.
Accepted inputs: D: -100 to 100 units; E: -100 to 100 units; Coordinate: choose x coordinate (0), y coordinate (1).
How the calculation works
center=(-D/2,-E/2)
Complete squares in x²+y²+Dx+Ey+F=0. Linear coefficients determine the center without needing F.
Worked example
With d -6 units, e 8 units, coordinate x coordinate, circle center coordinate from d and e is 3 units.
Assumptions and limits
Coefficient D/E units are coordinate units. This reports only the formal center; existence or radius of a real circle is not certified. Coordinate 0=x, 1=y.
