9x^2+4y^2-18x+16y-11=0

Lösung

9 x^{2} + 4 y^{2} - 18 x + 16 y - 11 = 0

Lösung

(h, k) = (1, - 2), a = 2, b = 3

Schritte zur Lösung

9 x^{2} + 4 y^{2} - 18 x + 16 y - 11 = 0

Rewrite

9 x^{2} + 4 y^{2} - 18 x + 16 y - 11 = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (1, - 2), a = 2, b = 3

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, - 2), b = 3, a = 2
