Beliebt Geometry >

(x+1)^2+(y+2)^2=4

Lösung

(x + 1)^{2} + (y + 2)^{2} = 4

Lösung

(a, b) = (- 1, - 2), r = 2

Schritte zur Lösung

(x + 1)^{2} + (y + 2)^{2} = 4

Rewrite

(x + 1)^{2} + (y + 2)^{2} = 4

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 1, - 2), r = 2

4x^2+4y^2-16x-32y=0

4 x^{2} + 4 y^{2} - 16 x - 32 y = 0

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

x^2+y^2+10x-14y+38=0

x^{2} + y^{2} + 10 x - 14 y + 38 = 0

4x^2+28x+4y^2-8y=-17

4 x^{2} + 28 x + 4 y^{2} - 8 y = - 17

x^{2} + y^{2} \leq 2 x + 1
