What else can I help you with?
Is every circle an ellipse?
Yes; the circle is a special case of an ellipse.
What is an eccentric circle?
For Ellipse: The 2 circles made using the the ellipse center as their center, and major and minor axis of the ellipse as the dia.For Hyperbola: 2 Circles with centers at the center of symmetry of the hyperbola and dia as the transverse and conjugate axes of the hyperbolaRead more: eccentric-circles
Which inventor found out that planets move in circles around the sun?
The ancient Greeks used Ptolemy's theory, based on circles, that was good enough for the accuracy needed at the time. Later Kepler in the 16th century discovered that an ellipse is a better model of a planetary orbit. In modern times it has been discovered that an ellipse is an approximation and that true orbits have no simple description. But the ellipse is a good enough model for many purposes.
Is all ellpses circles?
No. A circle is a special kind of ellipse.
What replaced the circle in with ellipse's in the heliocentric model of the universe?
Copernicus's Sun-centred (heliocentric) model of the planets' orbits used circles and epicycles, as the Ptolemaic model had done although the older model had the Earth at the centre. Kepler took the heliocentric idea and used it as the basis for extended calculations on the orbit Mars using new observations and measurements of unprecedented accuracy by his employer, Tycho Brahe. Mars's orbit had just enough eccentricity (9%) to allow a difference to show up between the earlier model and Kepler's new discovery of eliptical orbits. Kepler also found that the other planets had elliptical obits, but the eccentricity was lower. He developed his three laws of planetary motion now known as Kepler's laws.
What is a ellipse drawing?
"Elliptical" means they look like ellipses.
How Is circles different from an ellipse?
The outside of the circle is always the same distance from the centre. The outside of an ellipse is not the same distance from the centre all the way round.
What would the net be called for a cylindrical package could be made?
two circles and an ellipse
What happens to the graph of an ellipse when y is replaced by y plus 6?
The whole ellipse shifts down by 6 units.
What happens to the shape of an ellipse as the foci are moved closer together?
As the foci of an ellipse move closer together, the ellipse becomes more circular in shape. When the foci coincide, the shape is a circle. Note that circles are a subset of ellipses.
What is a path followed by a planet and satellite as it circles the sun in your solar system?
The path is called an orbit, and it's shaped like an ellipse.
What type of path does an object in orbit make?
An ellipse, or egg-shaped. Orbits are not very egg-shaped, though . . . they are almost circles.
