## How To Find The Perimeter Of An Ellipse

About the regression of an ellipse there is a long discussion going on and some papers have been wrote, because the least square fit is not very "trivial". The best solution I found turned out to be an eigenvector problem, and quite unefficient, I might add, nevertheless rather intriguing.

- The area of an ellipse is simple; it's just a generalization of the area of a circle, using the major and minor semiaxes instead of the radius: [math]A = \pi ab[/math] The perimeter of an ellipse turns out to be surprisingly difficult to calcula...
- On the Perimeter of an Ellipse Paul Abbott Computing accurate approximations to the perimeter of an ellipse is a fa-vorite problem of mathematicians, attracting luminaries such as Ramanu-jan [1, 2, 3]. As is well known, the perimeter of an ellipse with semimajor axis a and semiminor axis b can be expressed exactly as a complete elliptic integral of the second kind. -Approximate formulas can
- An ellipse is the locus of all points of the plane whose distances to two fixed points add to the same constant. An ellipse can be obtained as a result from the intersection of a cone by a plane in a way that produces a closed curve.
- The circumference C of an ellipse must be computed using calculus. To do this, we set up a Cartesian coordinate system. We put the origin at the center of the ellipse, the x-axis along the major axis, whose length is 2a, and the y-axis along the minor axis, whose length is 2b. The eccentricity e is defined by
