y^2=4-x^2

Solution

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

Solution

(a, b) = (0, 0), r = 2

Solution steps

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (0, 0), r = 2

Popular Examples

asymptotes of (x^2)/4-(y^2)/4 =1 asymptotes

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

axis (x^2)/9-(y^2)/4 =1 axis

\frac{x ^{2}}{9} - \frac{y ^{2}}{4} = 1

foci (y^2)/(36)-(x^2)/(64)=1 foci

\frac{y ^{2}}{36} - \frac{x ^{2}}{64} = 1

x = y - y^{2}

y^{2} - 8 x = 0
