Calculate Hyperbola properties

9 (y - 2)^{2} - 4 x^{2} = 36 :

Up-down Hyperbola with

(h, k) = (0, 2), a = 2, b = 3

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

= \frac{13}{2}

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

ecce n t r i c i t y 9 x^{2} - 9 y^{2} + 18 x + 36 y = 63

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

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

ecce n t r i c i t y + x^{2} - y^{2} = 4
