x^2+9y^2=18

Lösung

x^{2} + 9 y^{2} = 18

Lösung

(h, k) = (0, 0), a = 32, b = 2

Schritte zur Lösung

x^{2} + 9 y^{2} = 18

Rewrite

x^{2} + 9 y^{2} = 18

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = 32, b = 2

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 32, b = 2
