9y^2+x^2=81

Lösung

9 y^{2} + x^{2} = 81

Lösung

(h, k) = (0, 0), a = 9, b = 3

Schritte zur Lösung

9 y^{2} + x^{2} = 81

Rewrite

9 y^{2} + x^{2} = 81

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{9 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 9, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 9, b = 3

((x^2))/9+(((y-1)^2))/(25)=1

\frac{( x ^{2} )}{9} + \frac{( ( y - 1 ) ^{2} )}{25} = 1

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

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

x^{(2)}-4x+3y^{(2)}=-2

x^{(2)} - 4 x + 3 y^{(2)} = - 2

25x^{(2)}+4y^{(2)}=84

25 x^{(2)} + 4 y^{(2)} = 84

4x^2-16x+9y^2+54y=-61

4 x^{2} - 16 x + 9 y^{2} + 54 y = - 61
