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

Lösung

center

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

Lösung

(2, - 1)

Schritte zur Lösung

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

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

And the center is:

(2, - 1)
