achse x^2+2y^2+2x-8y+7=0

Lösung

achse

x^{2} + 2 y^{2} + 2 x - 8 y + 7 = 0

Lösung

semi - major axis a = 2, semi - minor axis b = 1

Schritte zur Lösung

x^{2} + 2 y^{2} + 2 x - 8 y + 7 = 0

Rewrite

x^{2} + 2 y^{2} + 2 x - 8 y + 7 = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

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