((x+2)^2)/4+((y-4)^2)/(16)=1

Lösung

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{16} = 1

(h, k) = (- 2, 4), a = 2, b = 4

Schritte zur Lösung

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{16} = 1

Rewrite

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{16} = 1

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (- 2, 4), a = 2, b = 4

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 2, 4), b = 4, a = 2

\frac{x ^{2}}{25} + \frac{y ^{2}}{49} = 1

\frac{x ^{2}}{15} + \frac{y ^{2}}{17} = 1

4 x^{2} + y^{2} + 40 x + 6 y + 95 = 0

\frac{x ^{2}}{64} + \frac{y ^{2}}{25} = 1

x^{2} + 2 y^{2} + 4 x + 2 y - 27 = 0
