leitkurve x^2=4y

Lösung

leitkurve

x^{2} = 4 y

Lösung

y = - 1

Schritte zur Lösung

Rewrite

x^{2} = 4 y

in the standard form:

4 \cdot 1 \cdot (y - 0) = (x - 0)^{2}

(h, k) = (0, 0), p = 1

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 - 1

x^{2} = - 16 y

y - x > - x^{2} - 1

((y+1)^2)/4-(x-5)^2=4

\frac{( y + 1 ) ^{2}}{4} - (x - 5)^{2} = 4

foki x= 1/8 y^2

f oc i x = \frac{1}{8} y^{2}

x^2-4y^2-2x+16y=20

x^{2} - 4 y^{2} - 2 x + 16 y = 20
