Conic Section (Conic)
-
is a curve obtained as the intersection of the surface of a right circular cone with a plane
-
Depending on the angle of the plane with respect to the cone, a conic section may be a circle, an ellipse, a parabola, or a hyperbola.

lesson 2-3: CIRCLE AND ITS
STANDARD FORMULA
What is a circle?
-
A circle is the set of points in a plane that lie a fixed distance, called the radius, from any point, called the center. The diameter is the length of a line segment passing through the center whose endpoints are on the circle. In addition, a circle can be formed by the intersection of a cone and a plane that is perpendicular to the axis of the cone.
-
In a rectangular coordinate plane, where the center of a circle with radius r is (h,k), we have:
Calculate the distance between (h,k) and (x,y) using the distance formula,
Squaring both sides leads us to the equation of a circle in standard form,
