Beliebt Geometry >

(2sqrt(x^2+y^2))^2=(3-y)^2

Lösung

(2 x^{2} + y^{2})^{2} = (3 - y)^{2}

Lösung

(h, k) = (0, - 1), a = 3, b = 2

Schritte zur Lösung

(2 x^{2} + y^{2})^{2} = (3 - y)^{2}

Rewrite

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

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{( 3 ) ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{2 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, - 1), a = 3, b = 2

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, - 1), b = 2, a = 3

25 x^{2} + 9 y^{2} = 25

x^2+2y^2-6x-20y+59=12

x^{2} + 2 y^{2} - 6 x - 20 y + 59 = 12

x^{2} + 4 y^{2} - 46 = 0

(x^2)/(a^2)+(y^2)/(b^2)-1=0

\frac{x ^{2}}{a ^{2}} + \frac{y ^{2}}{b ^{2}} - 1 = 0

x^{2} + 2 x + 3 y^{2} = 6
