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 do ellipses have two of?
The foci of an ellipse are two special points.
What is the difference between a circle and a ellipse?
Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse
What is an elongates circle or oval shape called?
Any ellipse is an oval shape. But all ovals are not all ellipses, some are nothing in particular.
What are the six conic sections?
A conic section is the intersection of a plane and a cone. By changing the angle and location of intersection, we can produce a circle, ellipse, parabola or hyperbola; or in the special case when the plane touches the vertex: a point, line or 2 intersecting lines.Traditionally, the three types of conic section are the hyperbola, the parabola, and the ellipse. The circle is a special case of the ellipse, and is of sufficient interest in its own right that it is sometimes called the fourth type of conic section.
What is the FOCI of a circle?
A circle is an ellipse with an eccentricity of zero. Both foci of that ellipse are at the same point. In the special case of the circle, that point is called the "center".
What conic sections describes a closed curve?
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
Is every circle an ellipse?
Yes; the circle is a special case of an ellipse.

Is the center of a circle called a focus or nucleus?
The center of a circle is called thecenter, in a way it is the focus of the special case of an ellipse which has equal major and semi major axes...
What is the name for '...'?
... is called an "ellipse"
Is all ellpses circles?
No. A circle is a special kind of ellipse.
What do ellipses have two of?
The foci of an ellipse are two special points.
What does the word ellipse means?
Ellipse is a term for an oval. Specifically it is a shape where the sum of the distance of every point on the ellipse to two points, called the foci, is equal.
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.
What is the adjective form of ellipse?
"Elliptical" or "Ellipsoidal".
