2x^2+y^2+2y=1

Lösung

2 x^{2} + y^{2} + 2 y = 1

Lösung

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

Schritte zur Lösung

2 x^{2} + y^{2} + 2 y = 1

Rewrite

2 x^{2} + y^{2} + 2 y = 1

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, - 1), a = 1, 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 = 1
