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

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

(h, k) = (0, 0), a = 1, b = 2

Solution steps

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = 1, b = 2

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 2, a = 1

12 x^{2} - 22 x + 16 y^{2} = 9

(x - 5)^{2} + \frac{( y - 4 ) ^{2}}{4} = 1

9 x^{2} + 36 y^{2} + 54 x - 288 y + 333 = 0

25 x^{2} + 9 y^{2} - 10 y - 216 = 0

(36 - 4 x^{2} - 9 y^{2}) = 0
