# Ellipses by YourMathGal

This collection of videos is from the video series Ellipses

This series of videos on ellipses begins with the standard equation of an ellipse centered at the origin, and how to graph it. It moves on to ellipses centered elsewhere in the plane, and the standard and general equation of an ellipse, as well as rewriting a standard equation as a general equation, and vice versa, which includes completing the square. Videos also cover how to recognize equations of ellipses, and writing equations of ellipses from looking at the graph.
