No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
No.
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.An ellipse has no sides and no corners. It is a smooth, continuous function, with no discontinuities. (This answer depends on your definition of a side - if you mean that a side is a straight line, then it is true, if not, then an ellipse has one side and no corners.)
"Ellipse" is a noun.
That's the definition of an ellipse.
It is the locus of points such that the sum of their distance from two distinct fixed points is a constant.
Most things orbit in an elliptical pattern. There is a technical definition of an ellipse but between you and me it is an oval.
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
One definition is that it is the locus of a point such that the sum of its distances from two fixed points (the foci) is a constant. There are several equivalent forms in coordinate geometry. Once the ellipse has been centred on the orign (using translations), (x/a)2 + (y/b)2 = 1 or x2 + (ey)2 = c2
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
No.
No.
No.
An ellipse has 2 foci. They are inside the ellipse, but they can't be said to be at the centre, as an ellipse doesn't have one.
A real-life example of an ellipse is the path that some heavenly bodies travel in space. Earth's path around the sun is elliptical.Informally, a flattened circle. You can read the Wikipedia article for a more formal definition, as well as to investigate its different properties.
