((x+1)^2)/9+((y-2)^2)/4 =1

Lösung

\frac{( x + 1 ) ^{2}}{9} + \frac{( y - 2 ) ^{2}}{4} = 1

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

Schritte zur Lösung

\frac{( x + 1 ) ^{2}}{9} + \frac{( y - 2 ) ^{2}}{4} = 1

Rewrite

\frac{( x + 1 ) ^{2}}{9} + \frac{( y - 2 ) ^{2}}{4} = 1

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

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

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

3 x^{2} + 2 y^{2} - 12 x + 8 y + 19 = 0

\frac{( x + 5 ) ^{2}}{16} + \frac{( y - 3 ) ^{2}}{25} = 1

0.25 x^{2} + y^{2} = 1

5 (x - 3)^{2} = 20 - 4 (y - 6)^{2}
