foki ((y+3)^2)/9-((x-1)^2)/(18)=1

Lösung

foki

\frac{( y + 3 ) ^{2}}{9} - \frac{( x - 1 ) ^{2}}{18} = 1

(1, - 3 + 33), (1, - 3 - 33)

Schritte zur Lösung

(h, k + c), (h, k - c)

Calculate Hyperbola properties

\frac{( y + 3 ) ^{2}}{9} - \frac{( x - 1 ) ^{2}}{18} = 1 :

Up-down Hyperbola with

(h, k) = (1, - 3), a = 3, b = 32

(1, - 3 + c), (1, - 3 - c)

Compute

c :

c = 3^{2} + (32)^{2} : 33

(1, - 3 + 33), (1, - 3 - 33)
