Beliebt Geometry >

4-4x^2-y^2>= 0

Lösung

4 - 4 x^{2} - y^{2} \geq 0

Lösung

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

Schritte zur Lösung

4 - 4 x^{2} - y^{2} \geq 0

Rewrite

4 - 4 x^{2} - y^{2} \geq 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

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

x^{2} + 5 y^{2} = 20

(1+b+ia)/(1+b-ia)=b+ia

\frac{1 + b + ia}{1 + b - ia} = b + ia

((x-0)^2)/4+((y-0)^2)/(16)=1

\frac{( x - 0 ) ^{2}}{4} + \frac{( y - 0 ) ^{2}}{16} = 1

((x+2)^2}{25}+\frac{(y-1)^2)/9 =1

\frac{( x + 2 ) ^{2}}{25} + \frac{( y - 1 ) ^{2}}{9} = 1

x^2+9y^2-8x+36y+4=0

x^{2} + 9 y^{2} - 8 x + 36 y + 4 = 0
