eccentricity+x^2=4y-2y^2

eccentricity

\frac{1}{2}

Decimal

0.70710 \dots

Solution steps

= \frac{a ^{2} - b ^{2}}{a}

Calculate ellipse properties

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

Ellipse with center

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

= \frac{( 2 ) ^{2} - 1 ^{2}}{2}

\frac{( 2 ) ^{2} - 1 ^{2}}{2} = \frac{1}{2}

= \frac{1}{2}
