foki-x^2+(y^2)/(20)=1

Lösung

foki

- x^{2} + \frac{y ^{2}}{20} = 1

(0, 21), (0, - 21)

Schritte zur Lösung

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

Calculate Hyperbola properties

- x^{2} + \frac{y ^{2}}{20} = 1 :

Up-down Hyperbola with

(h, k) = (0, 0), a = 25, b = 1

(0, 0 + c), (0, 0 - c)

Compute

c :

c = (25)^{2} + 1^{2} : 21

(0, 0 + 21), (0, 0 - 21)

Fasse zusammen
