center 11x^2+3x+3y^2+11y=0

Lösung

center

11 x^{2} + 3 x + 3 y^{2} + 11 y = 0

(- \frac{3}{22}, - \frac{11}{6})

Schritte zur Lösung

11 x^{2} + 3 x + 3 y^{2} + 11 y = 0

Rewrite

11 x^{2} + 3 x + 3 y^{2} + 11 y = 0

in the form of the standard ellipse equation

\frac{( x - ( - \frac{3}{22} ) ) ^{2}}{( \frac{679}{11 6} ) ^{2}} + \frac{( y - ( - \frac{11}{6} ) ) ^{2}}{( \frac{679}{3 22} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- \frac{3}{22}, - \frac{11}{6}), a = \frac{679}{11 6}, b = \frac{679}{3 22}

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- \frac{3}{22}, - \frac{11}{6}), b = \frac{679}{3 22}, a = \frac{679}{11 6}

And the center is:

(- \frac{3}{22}, - \frac{11}{6})
