8x^2+y^2+4y=0

Lösung

8 x^{2} + y^{2} + 4 y = 0

Lösung

(h, k) = (0, - 2), a = \frac{1}{2}, b = 2

Schritte zur Lösung

8 x^{2} + y^{2} + 4 y = 0

Rewrite

8 x^{2} + y^{2} + 4 y = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, - 2), a = \frac{1}{2}, b = 2

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, - 2), b = 2, a = \frac{1}{2}
