81x^2+9y^2=9

Lösung

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

Lösung

(h, k) = (0, 0), a = \frac{1}{3}, b = 1

Schritte zur Lösung

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = \frac{1}{3}, b = 1

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 1, a = \frac{1}{3}
