Circle Equations
1. Centre-radius form:
Circle having centre (x0, y0) and radius r.
The equation of the circle can be represented as:
General Equation of a Circle:
where, g
, f
, and c
are constants.
Therefore,
2. Parametric form:
Circle having centre (x0, y0) and radius makes an angle t with the positive direction of x-axis, then t is called the parameter
.
The equation of the circle can be represented as:
for,
