foki ((y+3)^2)/4-((x+1)^2)/(16)=1

Lösung

foki

\frac{( y + 3 ) ^{2}}{4} - \frac{( x + 1 ) ^{2}}{16} = 1

(- 1, - 3 + 25), (- 1, - 3 - 25)

Schritte zur Lösung

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

Calculate Hyperbola properties

\frac{( y + 3 ) ^{2}}{4} - \frac{( x + 1 ) ^{2}}{16} = 1 :

Up-down Hyperbola with

(h, k) = (- 1, - 3), a = 2, b = 4

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

Compute

c :

c = 2^{2} + 4^{2} : 25

(- 1, - 3 + 25), (- 1, - 3 - 25)
