Foci of Ellipse Calculator
Result
Foci Of Ellipse Find the foci of an ellipse from its semi-major and semi-minor axes. Calculate focal distance (c) and eccentricity. The foci are the two fixed points that define an ellipse: any point on the ellipse has a constant sum of distances to the t — free online calculator.
Formula
- Foci of Ellipse Calculator calculates its result from Sqrt, A. It uses the formula c = √(a² - b²); Eccentricity = c/a. Change any input to recalculate the result instantly.
- The main inputs are Sqrt, A. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Foci of Ellipse
- Sqrt: 2
- A: 3
Using Sqrt = 2, A = 3, the calculated result is 0.6666666667.
