-2x^2+1-y^2=0

- 2 x^{2} + 1 - y^{2} = 0

(h, k) = (0, 0), a = \frac{1}{2}, b = 1

Solution steps

- 2 x^{2} + 1 - y^{2} = 0

Rewrite

- 2 x^{2} + 1 - y^{2} = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = \frac{1}{2}, b = 1

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 1, a = \frac{1}{2}
