WebNov 24, 2024 · Eccentricity: Examples. Example 1. Find the eccentricity of the ellipse 9x2 25 y2 = 225. Solution: The equation of the ellipse in the standard form is x 2 /a 2 y 2 /b 2 = 1. Thus rewriting 9x 2 25 y 2 = 225, we get x 2 /25 y 2 /9 = 1. Comparing this with the standard equation, we get a 2 = 25 and b 2 = 9. WebMay 14, 2015 · Thus, the "distance-to-focus-over-distance-to-directrix" ratio and the "focal-radius-over-major-radius" ratio (when defined) are the same constant that we happen to call the "eccentricity" of a conic. This discussion reveals the geometric meaning of that number. I suspect that most students these days had no idea that there is such meaning ...

WebDec 15, 2024 · 2. See also this answer, which demonstrates that the eccentricity is also equal to sin ∠ S sin Q, where S is the angle of inclination of the plane that cuts a cone to make a conic section, and Q gives the steepness of the cone itself. Since a circle is cut by a "horizontal" plane, S = 0. (Note, too, that the directrix is the line where the ...
