Understanding Ellipse Eccentricity
Eccentricity (e) measures how much an ellipse deviates from a perfect circle. It's a value between 0 and 1:
- e = 0: Perfect circle.
- 0 < e < 1: Ellipse shape, closer to 0 means more circular.
- e close to 1: Highly elongated ellipse.
It's calculated using the formula: $$e = \sqrt{1 - \frac{b^2}{a^2}}$$, where a is the semi-major axis and b is the semi-minor axis. This tool helps you quickly find and visualize this property.
