leitkurve y^2=-12x

Lösung

leitkurve

y^{2} = - 12 x

Lösung

x = 3

Schritte zur Lösung

Rewrite

y^{2} = - 12 x

in the standard form:

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

(h, k) = (0, 0), p = - 3

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 - (- 3)

Fasse zusammen

x = 3

(x+92)^2+(y+54)^2=73

(x + 92)^{2} + (y + 54)^{2} = 73

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

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

(x^2)/4+(y^2)/(64)=1

\frac{x ^{2}}{4} + \frac{y ^{2}}{64} = 1

foki ((x-7)^2)/4+((y+3)^2)/(16)=1

f oc i \frac{( x - 7 ) ^{2}}{4} + \frac{( y + 3 ) ^{2}}{16} = 1

(x^2)/(64)+(y^2)/(100)=1

\frac{x ^{2}}{64} + \frac{y ^{2}}{100} = 1
