(x^2)/9+((y+5)^2)/(25)=1

Lösung

\frac{x ^{2}}{9} + \frac{( y + 5 ) ^{2}}{25} = 1

(h, k) = (0, - 5), a = 3, b = 5

Schritte zur Lösung

\frac{x ^{2}}{9} + \frac{( y + 5 ) ^{2}}{25} = 1

Rewrite

\frac{x ^{2}}{9} + \frac{( y + 5 ) ^{2}}{25} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{3 ^{2}} + \frac{( y - ( - 5 ) ) ^{2}}{5 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, - 5), a = 3, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, - 5), b = 5, a = 3

\frac{x ^{2}}{16} + \frac{y ^{2}}{64} = 1

4 x^{2} + 3 y^{2} - 5 x + 2 y + 1 = 0

\frac{x ^{2}}{4} + \frac{y ^{2}}{10} = 1

4 x^{2} + y^{2} + 8 x - 10 y + 25 = 0

9 x^{(2)} + 25 y^{(2)} - 36 x + 50 y - 839 = 0
