X^2+Y^2-4=0

Lösung

X^{2} + Y^{2} - 4 = 0

Lösung

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

Schritte zur Lösung

X^{2} + Y^{2} - 4 = 0

Rewrite

X^{2} + Y^{2} - 4 = 0

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

x^2+y^2+2x+6y+1=0

x^{2} + y^{2} + 2 x + 6 y + 1 = 0

(x-2)^2+(y-1)^2=2^2

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

2 x^{2} + 2 y^{2} - 4 x + 18 y = 7

x^2+y^2+4x-8y-25=0

x^{2} + y^{2} + 4 x - 8 y - 25 = 0
