eccentricity (x^2)/8+(y^2)/4 =1

eccentricity

\frac{1}{2}

Decimal

0.70710 \dots

Solution steps

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

Calculate ellipse properties

\frac{x ^{2}}{8} + \frac{y ^{2}}{4} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 22, b = 2

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

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

= \frac{1}{2}
