Beliebt Geometry >

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

Lösung

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

Lösung

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

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

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

Therefore the circle properties are:

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

(x-1)^2+(y+2)^2=9

(x - 1)^{2} + (y + 2)^{2} = 9

(x+2)^2+(y-1)^2=25

(x + 2)^{2} + (y - 1)^{2} = 25

9x^2+9y^2+42x-54y+49=0

9 x^{2} + 9 y^{2} + 42 x - 54 y + 49 = 0

(x-7/4)^2+(y+3/4)^2= 169/16

(x - \frac{7}{4})^{2} + (y + \frac{3}{4})^{2} = \frac{169}{16}

(x-2)^2+(y-1)^2=16

(x - 2)^{2} + (y - 1)^{2} = 16
