Conic sections are formed when you intersect a plane with a cone. In this tutorial, you will learn more about what makes conic sections special.

Learn how to analyze an equation of a circle that is not given in the standard form. For example, find the center of the circle whose equation is x^2+y^2+4x-5=0.

Learn about the foci of an ellipse, which are two points for which the sum of the distances from any point on the ellipse is constant.

A parabola is the set of all points equidistant from a point (called the focus) and a line (called the directrix). In this tutorial you will learn about the focus and the directrix, and how to find the equation of a parabola given its focus and directrix.

A hyperbola is the set of all points whose distances from two specific points (called the foci) have the same difference. Learn more about it here.

Learn about the foci of the hyperbola: How to find them from the hyperbola's equation and how to find the equation when given the foci.

Generalize what you learned about hyperbolas to study hyperbolas whose center can be any point.
