Cartesian Equation of a Circle

The video tutorial explores conic sections, focusing on circles. It defines a circle as a locus of points equidistant from a center and explains its properties using coordinate geometry. The Cartesian equation of a circle is derived and simplified, and the video discusses how to find a circle's center and radius from its general equation. It also covers intercepts, point positions relative to a circle, and symmetry. The isoperimetric theorem is introduced through the story of Queen Dido, illustrating the circle's unique properties in geometry.
