A is the set of all points in a plane that are equidistant from a given point in the plane called the. is a point on the circle is the center r is the radius circle center
3
Equation of a Circle : General Form of a Circle : *In general form, a circle has two square variables, both with the same positive coefficients
4
D ETERMINE THE EQUATION OF THE FORM FOR THE CIRCLE WITH THE GIVEN CENTER AND RADIUS. 1.
5
D ETERMINE THE EQUATION OF THE FORM FOR THE CIRCLE WITH THE GIVEN CENTER AND RADIUS. 2.
6
In order to graph an equation in general form, we need to put it in the form. We can do this by completing the square !
