Find the general form, Ax2+Ay2+Dx+Ey+F=0, by identifying the coefficients A,D,E,&F center:(0,1); r=1 (x-0)2+(y-1)2=1 x2+y2-2

siniylev [52]

Answer:

The value of A is 1, D is 0, E is -2 and F is 0.

Step-by-step explanation:

The given equation is

$Ax^2+Ay^2+Dx+Ey+F=0$ ...(1)

The standard form of the circle is

$(x-h)^2+(y-k)^2=r^2$

Where, (h,k) is the center of the circle and r is the radius.

$(x-0)^2+(y-1)^2=1$

$x^2+y^2-2y+1-1=0$

$x^2+y^2-2y=0$

It can be written as

$x^2+y^2+0x-2y+0=0$ ....(2)

On comparing (1) and (2) we get.

$A=1$

$D=0$

$E=-2$

$F=0$

Therefore the value of A is 1, D is 0, E is -2 and F is 0.
