9x^2+y^2=9

Solution

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

Solution

(h, k) = (0, 0), a = 1, b = 3

Solution steps

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = 1, b = 3

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 3, a = 1

Popular Examples

x^{2} = - 20 y

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

foci (x^2)/4+((y+4)^2)/(25)=1 foci

\frac{x ^{2}}{4} + \frac{( y + 4 ) ^{2}}{25} = 1

foci (y^2)/4-x^2=1 foci

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

(y^2}{16}-\frac{x^2)/9 =1

\frac{y ^{2}}{16} - \frac{x ^{2}}{9} = 1
