9y^2+x^2=9

Lösung

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

Lösung

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

Schritte zur Lösung

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

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