A special form of the ellipse is called a circle. In a circle, the distance from the center to any point on the boundary is constant, meaning all points are equidistant from the center. This can be seen as an ellipse where the two foci coincide at the center, resulting in equal semi-major and semi-minor axes.

How can you tell when you are going to graph and Ellipse?

ax^2+by^2=k is an ellipse this is not in standard form which is x^2/a^2+y^2/b^2=1 but you will often see ellipses written this way. ellipses are also commonly written in their parametric form which is x=ccos(t) and y=dsin(t). finally a circle is a special case of an ellipse and if a b or k are 0 or negative it is not an ellipse. c and d can be positive but not 0.

What is the difference between circle and ellipse?

The simple answer is that an ellipse is a squashed circle.A more precise answer is that an ellipse is the locus (a collection) of points such that the sum of their distances from two fixed points (called foci) remains a constant. A circle is the locus of points that are all the same distance from a fixed point. If the two foci are moved closer together, the ellipse becomes more and more like a circle and finally, when they coincide, the ellipse becomes a circle. So, a circle is a special case of an ellipse.
