x^2+8(y+5)^2=20

Lösung

x^{2} + 8 (y + 5)^{2} = 20

Lösung

(h, k) = (0, - 5), a = 25, b = \frac{5}{2}

Schritte zur Lösung

x^{2} + 8 (y + 5)^{2} = 20

Rewrite

x^{2} + 8 (y + 5)^{2} = 20

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, - 5), a = 25, b = \frac{5}{2}

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, - 5), a = 25, b = \frac{5}{2}
