achse 4x^2+y^2+8x-4y+4=0

Lösung

achse

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

Lösung

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

Schritte zur Lösung

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

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