leitkurve x^2=-16y

Lösung

leitkurve

x^{2} = - 16 y

Lösung

y = 4

Schritte zur Lösung

Rewrite

x^{2} = - 16 y

in the standard form:

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

(h, k) = (0, 0), p = - 4

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 - (- 4)

x^{2} - 6 x - 4 y + 5 = 0

(x^2)/(81)+(y^2)/(49)=1

\frac{x ^{2}}{81} + \frac{y ^{2}}{49} = 1

x^{2} + y^{2} = 20

12x^2+20y^2-12x+40y-37=0

12 x^{2} + 20 y^{2} - 12 x + 40 y - 37 = 0

y^{2} = 24 x
