DemonX: Im having problems plotting circles.
The equation of a circle with centre (0,0) and radius r is
x
2 + y
2 = r
2 The equation of a circle with centre (h,k) and radius r is
(x-h)
2 + (y-k)
2 = r
2 If you are given an equation in a different form then you will have to change it into one of these forms before you can read of the centre and the radius and consequentally graph it.
Maybe you should aske a specific question.
but I hope that this will help.
