What to Focus On

  • Circle: locus of points equidistant from a fixed point.
  • Centre is the fixed point.
  • Radius is the distance from the centre to the circle and is always positive.

  • Standard equation: (x-h)^2 + (y-k)^2 = r^2.
  • It is obtained from the distance formula.
  • If the centre is (0,0), the equation is x^2 + y^2 = r^2.

  • General equation: x^2 + y^2 + 2gx + 2fy + c = 0.
  • Centre = (-g, -f).
  • Radius = sqrt(g^2 + f^2 - c).

Common Mistakes to Avoid

Any second-degree equation with x squared and y squared represents a circle.

The radius in the general equation is sqrt(g^2+f^2+c).

The centre of x^2+y^2+2gx+2fy+c=0 is (g,f).
