A hole, though shaped like an ellipse, in which this well-hung stud had placed it would look as if a compass traced it.
On Dec. 18, a triumphant Johnson appeared on the ellipse outside the White House to light the national Christmas tree.
These marks will then represent the diameter of the ellipse across its major axis.
It is not allowed to move exactly in an ellipse, nor is the earth exactly in the focus.
Now it is remarkable that this apparent path is still an ellipse.
These points are your centers for scribing the long sides of the ellipse.
The other two being intersected at an angle, will each be an ellipse.
Is the orbit that of an ellipse, or a circle, or a parabola?
The earth's orbit is an ellipse, one of the foci of which is occupied by the sun.
Man forms the idea of an ellipse, and ascertains the laws of ellipses.
1753, from French ellipse (17c.), from Latin ellipsis "ellipse," also, "a falling short, deficit," from Greek elleipsis (see ellipsis). So called because the conic section of the cutting plane makes a smaller angle with the base than does the side of the cone, hence, a "falling short." First applied by Apollonius of Perga (3c. B.C.E.).
In geometry, a curve traced out by a point that is required to move so that the sum of its distances from two fixed points (called foci) remains constant. If the foci are identical with each other, the ellipse is a circle; if the two foci are distinct from each other, the ellipse looks like a squashed or elongated circle.
Note: The orbits of the planets and of many comets are ellipses.
