Calculate Hyperbola properties

\frac{x ^{2}}{81} - \frac{y ^{2}}{9} = 1 :

Right-left Hyperbola with

(h, k) = (0, 0), a = 9, b = 3

= \frac{9 ^{2} + 3 ^{2}}{9}

= \frac{10}{3}

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

ecce n t r i c i t y \frac{y ^{2}}{64} - \frac{x ^{2}}{36} = 1

ecce n t r i c i t y \frac{x ^{2}}{9} - \frac{y ^{2}}{25} = 1

ecce n t r i c i t y \frac{y ^{2}}{25} - \frac{x ^{2}}{16} = 1

ecce n t r i c i t y \frac{( x + 1 ) ^{2}}{4} - (y - 5)^{2} = 4
