81X^2+49Y^2=3969

Lösung

81 X^{2} + 49 Y^{2} = 3969

Lösung

(h, k) = (0, 0), a = 7, b = 9

Schritte zur Lösung

81 X^{2} + 49 Y^{2} = 3969

Rewrite

81 X^{2} + 49 Y^{2} = 3969

in the form of the standard ellipse equation

\frac{( X - 0 ) ^{2}}{7 ^{2}} + \frac{( Y - 0 ) ^{2}}{9 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 7, b = 9

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 9, a = 7
