Writing the Equation of a Circle

[urfacewayne]

Thanks

[tilly1995]

Good Video!! very helpful

[pbeasr]

it should be in a plane because all points an equal difference is a sphere

[Wuzzi55]

it's : X2 - X1 and Y2 - Y1,

not X1 - X2 and Y1 - Y2

because the two refers to the second point which you look at, after the first point on the x and y axis.

[TheMathsstudent]

@Wuzzi55 he substitutes the values into what x1 and y1 would be anyway, so he still gets the correct answer. But it is confusing

[brettouche]

@Wuzzi55 Once you square the numbers in the brackets you get the same answer

[feelthemelody1]

@Wuzzi55 its the same thing, try it
