Calculate ellipse properties

9 x^{2} + 49 y^{2} = 441 :

Ellipse with center

(h, k) = (0, 0), a = 7, b = 3

= \frac{7 ^{2} - 3 ^{2}}{7}

\frac{7 ^{2} - 3 ^{2}}{7} = \frac{2 10}{7}

= \frac{2 10}{7}

ecce n t r i c i t y \frac{x ^{2}}{324} + \frac{y ^{2}}{400} = 1

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

ecce n t r i c i t y 4 x^{2} + 3 y^{2} + 24 x + 36 y + 72 = 0

ecce n t r i c i t y \frac{5}{81} x^{2} + \frac{y ^{2}}{9} = 1

ecce n t r i c i t y 3 x^{2} + y^{2} - 24 x = - 39
