leitkurve x^2=-8y

Lösung

leitkurve

x^{2} = - 8 y

Lösung

y = 2

Schritte zur Lösung

Rewrite

x^{2} = - 8 y

in the standard form:

4 (- 2) (y - 0) = (x - 0)^{2}

(h, k) = (0, 0), p = - 2

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(0, 0)

y-coordinate

y = 0 - p

y = 0 - (- 2)
