Pre -Calculus
Pre-calculus is the study of the mathematical prerequisites for calculus, including algebra, trigonometry and analytical geometry. The unusual thing about pre-calculus topics is that they don’t directly involve calculus. Instead, they give students a strong foundation that will be used throughout their calculus studies
CONIC SECTIONS
In Pre - Calculus, conic sections are the nondegenerate curves generated by the intersections of a plane with one or two nappes of a cone. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though historically it was sometimes called a fourth type.

CIRCLE
A circle is the set of points in a plane that are equidistant from a given point . The distance from the center is called the radius, and the point is called the center. Twice the radius is known as the diameter . The angle a circle subtends from its center is a full angle, equal to or radians.
This pre-calculus video tutorial explains how to graph circles in standard and how to write equations of circles in standard form. This video on conic sections contains plenty of examples and practice problems.
