axis 3x^2+3y^2-18y=0

Solution

axis

3 x^{2} + 3 y^{2} - 18 y = 0

Solution

semi - major axis b = 3, semi - minor axis a = 3

Solution steps

3 x^{2} + 3 y^{2} - 18 y = 0

Rewrite

3 x^{2} + 3 y^{2} - 18 y = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

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

Popular Examples

axis 4x^2+y^2=4 axis

4 x^{2} + y^{2} = 4

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

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

axis ((x-12)^2)/(100)+((y+7)^2)/(36)=1 axis

\frac{( x - 12 ) ^{2}}{100} + \frac{( y + 7 ) ^{2}}{36} = 1

((y+4)^2)/9-((x-3)^2)/(25)=1

\frac{( y + 4 ) ^{2}}{9} - \frac{( x - 3 ) ^{2}}{25} = 1

25y^2-16x^2-400=0

25 y^{2} - 16 x^{2} - 400 = 0
