One can create a perfect ellipse using two pins on a piece of string and a pencil. Place the pins at opposite sides and then loop the string around them. Finally place the pencil in the loops and pull it around the pins to draw the ellipse.

isn't it an arty word, like when you draw an ellipse-- so when you see/draw something with an ellipse you call it an elliptical drawing


What is the diameter of a elliptical galaxy?

Variable, as an ellipse is not a perfect circle.


Does an ellipse have 4 straight lines?

An ellipse does not have four straight lines; it is a smooth, continuous curve defined as the set of points where the sum of the distances to two fixed points (the foci) is constant. While you can draw tangents that touch the ellipse at various points, the shape itself is not composed of straight lines. However, one can inscribe a rectangle within an ellipse that has four straight sides, but that is separate from the ellipse itself.


Define the focus and the eccentricity of an ellipse?

A circle is perfectly round, and has one center. An ellipse is like a circle with TWO "centers", and each "center" is called a "focus". The plural of "focus" is "foci". Take a piece of string and tie a loop in each end. Put a pin through the loops, and hold it still in the center of the circle. Place the tip of your pencil at the center of the string, and you can draw a circle by keeping the string taut. Now take TWO pins, and put one pin at each end of the string; place the pins at some short distance apart, and hold them there. Place your pencil and draw, and the shape you draw will be an ellipse. The two pinpoints are the focuses, or foci, of the ellipse. Eccentricity is a measure of how far the ellipse varies from a circle. An ellipse with an eccentricity of zero _IS_ a circle, while an eccentricity of 1.0 is a straight line, with that string stretched out straight. In astronomy, every natural orbit is an ellipse.


What does the eccentricity of an ellipse tell you about the ellipse?

The eccentricity of an ellipse, denoted as ( e ), quantifies its deviation from being circular. It ranges from 0 to 1, where an eccentricity of 0 indicates a perfect circle and values closer to 1 signify a more elongated shape. Essentially, the higher the eccentricity, the more stretched out the ellipse becomes. Thus, eccentricity provides insight into the shape and focus of the ellipse.

Does the eccentricity E gives us the size of an ellipse?

No - The eccentricity only tells us the degree to which the ellipse is flattened with respect to a perfect circle.
