Program Name Ellipse
Description
This program displays a number table of the following values based on input of the foci of an
ellipse, the sum of the distance between the loci and foci, and the pitch (step size) of X.
Y1: Coordinate values of upper half of ellipse
Y2: Coordinate values of lower half of ellipse
Y3: Distances between right focus and loci
Y4: Distances between left focus and loci
Y5: Sum of Y3 and Y4
Next, the program plots the foci and values in Y1 and Y2.
Purpose
This program shows that the sums of the
distances between the loci and two foci of an
ellipse are equal.
