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

Lösung

- x^{2} - \frac{y ^{2}}{4} = - 1

Lösung

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

Schritte zur Lösung

- x^{2} - \frac{y ^{2}}{4} = - 1

Rewrite

- x^{2} - \frac{y ^{2}}{4} = - 1

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+4y^2-2x+16y+1=0

x^{2} + 4 y^{2} - 2 x + 16 y + 1 = 0

4x^2+2y^2-2x+4y-7=0

4 x^{2} + 2 y^{2} - 2 x + 4 y - 7 = 0

((x-4)^2)/(36)+(y^2)/(20)=1

\frac{( x - 4 ) ^{2}}{36} + \frac{y ^{2}}{20} = 1

x^{2} + y^{2} - 7 y = 0

(x^2)/7+(y^2)/5 =1

\frac{x ^{2}}{7} + \frac{y ^{2}}{5} = 1
