Formula and methodology
Formula: For Ax²+Cy²+Dx+Ey+F=0 with no xy term, center = (−D/(2A), −E/(2C)).
Completing the square in each independent coordinate exposes the translation that places the ellipse center.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- x² coefficient A — minimum 1.0E-6; maximum 1000000
- y² coefficient C — minimum 1.0E-6; maximum 1000000
- x coefficient D — minimum -1000000; maximum 1000000
- y coefficient E — minimum -1000000; maximum 1000000
Worked example
| Input | Value |
|---|---|
| x² coefficient A | 2 |
| y² coefficient C | 3 |
| x coefficient D | -4 |
| y coefficient E | 6 |
Center = (1, −1).
Assumptions and limits
- A and C are positive so the quadratic is axis-aligned and ellipse-like after the constant is supplied.
- The xy cross-term and rotation are excluded from this compact center calculation.
- The constant term is not needed to determine the center.
