👉 The eccentricity of a point in space is defined as the ratio of the distance from the point to the center of the sphere or plane containing it, expressed as a fraction. This concept is crucial for understanding various geometric shapes and their properties. In geometry, an ellipse is a type of conic section that extends infinitely far away from a fixed point called the focus at infinity. The eccentricity of an ellipse is defined as the ratio of the distance from any point on the ellipse to its center to
