# Who discovered ellipses?

The ellipses were discovered in the 17th century by one JohannesKepler. Johannes Kepler discovered that the orbits along which theplanets travel around the Sun are ellipses with the Sun at onefocus, in his first law of planetary motion.

# What is an ellipse?

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.

# How do you do circumference?

To work out the circumference of a circle, you need to do pi multiplied by the diameter. The diameter is the distance from one end to the other. Pi = 22/7 or 3.141...

# What are the characteristics of an ellipse?

Here's one way to think about an elllipse: -- Mark two black dots on a piece of paper, or stick two nails into a piece of wood. -- Mark a dot anywhere else on the paper, just not on the line between the first two. -- Measure the distance of the new dot from the first one, and from the s…econd one, then add those two distances. -- If you draw another dot at every place on the paper where the sum of the two distances from the first two dots is the same sum , you'll have an ellipse. -- The first two black dots, or the nails, are the foci ( focus es) of the ellipse. -- The farther apart the first two black dots are, the more eccentric the ellipse is ... skinny compared to its length. -- When the first two black dots get so close together that they're the same dot, then you have an ellipse whose eccentricity is zero , and there's a special name for that ellipse. It's called a ' circle '. Easy way to draw it: -- Tie a piece of string in a loop. -- Drop the loop of string around the two nails. -- Put a pencil point into the loop. Pull it out to the side until there's no slack in the loop. -- Run the pencil around, keeping it against the string with no slack in the loop. You're drawing an ellipse. If you pull out one nail, you're drawing a circle. (MORE)

# What is the period of an ellipse?

1. An ellipse is an oval shape. The orbits of planets are elliptical, i.e. oval shaped. The period of rotation of different planets in their respective elliptical orbits around the sun differs from planet to planet. The period of time that planet Mercury takes to complete its elliptical orbit arou…nd the sun is about 88 sidereal days, compared to 365.2564 sidereal days for the Earth..
2. An eclipse is when light from one celestial body is obscured by another celestial body..
A solar eclipse is when the sun's light is blocked from the earth by the moon. This eclipse can be total or partial, depending on where on the earth the observer is situated. And the duration of the eclipse varies slightly according to the time of year and respective relative positions of the three celestial bodies involved. A total solar eclipse can be about seven to seven and a half minutes long. Partial eclipses are not as long..
Planets other than the earth also experience eclipses as their moons cause shadows on their surfaces..
A lunar eclipse occurs when the earth comes between the sun and the moon, blocking the sun's light from the moon and darkening its appearance. A total lunar eclipse can last over an hour, but if we include the partial eclipse time, the overall period/duration of the eclipse can be over three hours..

# How is a circle similar to an ellipse?

How is a circle similar to an ellipse? The eccentricity of a circle is zero. The eccentricity of an ellipse which is not a circle is greater than 0, but less than 1. The eccentricity of a parabola is 1 The eccentricity of a hyperbola is greater than 1 Definition of eccentric a person wi…th an unusual or odd personality bizarre: conspicuously or grossly unconventional or unusual; . A circle is the perfect shape, all point are equidistant from the center. I believe we could agree that the circle has no eccentricity!! The eccentricity of a circle is zero. . On the other hand the ellipse has points that 2 centers, a little eccentric. The farther the 2 points are apart the more eccentric the ellipse is. If you take any point on the ellipse, the sum of the distances to the focus points is constant. The eccentricity of an ellipse which is not a circle is greater than 0, but less than 1. If you stretch the ellipse too far it will break open and be a parabola. The eccentricity of a http://wiki.answers.com/wiki/Parabola is 1. The parabola just keeps spreading out in both directions. At least it is still symmetrical. It has bottom (vertex),but the top just keeps spreading out. The eccentricity of a parabola is 1 The eccentricity of a hyperbola is greater than 1 The points on a hyperbola get close to the x-axis and y-axis, but never touch either axis. The eccentricity of a circle is zero. Think about the equation of each of these shapes Circle x^2 + y^2 = r ^2 How beautiful y^2 = r ^2 - x^2 The eccentricity of an ellipse which is not a circle is greater than 0, but less than 1.

# What is an ellipse called when it has the minimum eccentricity?

When the two foci of an ellipse are at the same point, then the ellipse has zero eccentricity, and is known as a "circle".

# How you answer circumference?

1) First, Measure the Diameter. The diameter is the distance across a circle. It can be be seen as cutting a circle in half. 2) When the diameter is too large to determine, estimate the radius. The radius can be seen as half of the diameter. Once you picture the radius, multiply it by 2. 3) Now you …may find the Circumference. Once you find the Diameter of a circle, you multiply it by pi. Pi is the value of 3.14 . Once you multiply the Diameter by pi, you find the Circumference! For example, if a jogger estimated diameter of a circular path as 200 meters across, then circumference would be 200 times 3.14 . 4) Make sure to verify your units of measurement. If your Diameter is in meters, your circumference must be in meters also. You just found the Circumference of a circle!!! (MORE)

# How do you find foci of ellipse?

Let's start with the equation of the ellipse. x 2 /a 2 +y 2 /b 2 =1 This ellipse is centered at the origin, and we can move it by subtracting h from x and k from y and then squaring that quantity. For example, if we move it h units horizontally, we have (x-h) 2 instead of just x 2 . In an…y case. b 2 =a 2 -c 2 . The foci are located 2c units part. So if it is centered at the origin, we can just find 2c and each focus is at + or - c. If we move the ellipse, we can still do the same thing, we just need to take into account how much we moved it. Here is an example to help you see it. Vertices (4,0) and (-4,0) center (0,0) End points of minor axis (0,2) and (0,-2) Foci at (3.5,0) and (-3.5,0) (MORE)

Because people like men and then the moon laughs at us. And sometimes gets scard so then the sun gets super gay with the moon and start rocking the bed.

# Is an ellipse a function?

No. A function is a "graph" the survives the "vertical line test". Namely, it is for every x in its domain, there can be one and only one f(x) in its co-domain. An ellipse clearly fails it at everywhere except it's two vertex. But an ellipse can be thought as two separate functions. A standard el…lipse relation, x^2 / a + (y)^2 / b = 1, can be thought as two separate real functions of y1 and y2. where y1 = -y2 exactly. (MORE)
