Calculate ellipse properties

x^{2} + 4 y^{2} - 6 x + 8 y + 9 = 0 :

Ellipse with center

(h, k) = (3, - 1), a = 2, b = 1

= \frac{2 ^{2} - 1 ^{2}}{2}

\frac{2 ^{2} - 1 ^{2}}{2} = \frac{3}{2}

= \frac{3}{2}

ecce n t r i c i t y 2 x^{2} + 7 y^{2} = 14

ecce n t r i c i t y 27 x^{2} + 48 y^{2} - 54 x - 192 y - 213 = 0

ecce n t r i c i t y \frac{x ^{2}}{9} + \frac{y ^{2}}{16} = 1

ecce n t r i c i t y \frac{x ^{2}}{8 ^{2}} + \frac{y ^{2}}{4 ^{2}} = 1

ecce n t r i c i t y 2 x^{2} + y^{2} - 8 y - 2 x + 1 = 0
