((x+2)^2)/9+((y-7)^2)/(64)=1

Lösung

\frac{( x + 2 ) ^{2}}{9} + \frac{( y - 7 ) ^{2}}{64} = 1

Lösung

(h, k) = (- 2, 7), a = 3, b = 8

Schritte zur Lösung

\frac{( x + 2 ) ^{2}}{9} + \frac{( y - 7 ) ^{2}}{64} = 1

Rewrite

\frac{( x + 2 ) ^{2}}{9} + \frac{( y - 7 ) ^{2}}{64} = 1

in the form of the standard ellipse equation

\frac{( x - ( - 2 ) ) ^{2}}{3 ^{2}} + \frac{( y - 7 ) ^{2}}{8 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, 7), a = 3, b = 8

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 2, 7), b = 8, a = 3
