leitkurve y^2=4ax

Lösung

leitkurve

y^{2} = 4 a x

Lösung

x = - a

Schritte zur Lösung

Rewrite

y^{2} = 4 a x

in the standard form:

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

(h, k) = (0, 0), p = a

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

- p

from the center

(0, 0)

x-coordinate

x = 0 - p

x = 0 - a

Fasse zusammen

x = - a
