Equation of an ellipse using the axes lengths and its center

2.2.2.5.4.1 Equation of an ellipse using foci and a point on the ellipse

This wizard is used to find the equation of an ellipse, given its foci and one point
on the ellipse.

It can be accessed by clicking on Wizard Button | Ellipse | Equation of an
ellipse using its foci and a point on the ellipse.

To find the equation of an ellipse:
Enter the foci: either { (x1 ,y1 ) , (x1 ,y2 ) } or { (x1 ,y1 ) , (x2 ,y1 ) }.
Enter the point: (x3 ,y3 ).
Click on the "Solve Step" button to see the next step or "Solve all" button
to see all steps.

Note that either the x or y coordinate points of the foci must be equivalent;
otherwise the given points will not form the ellipse. Note also that the foci points
must be differ from each other.

If you need an explanation for any particular step, click on the step and then
click on the "Explain" button.
2.2.2.5.4.2 Equation of an ellipse using end points of major axis and length of minor axis

This wizard is used to find the equation of an ellipse, given the end points of the
major axis and the length of the minor axis.

It can be accessed by clicking on Wizard Button | Ellipse | Equation of an
ellipse using the end points of the major axis and the length of the minor
axis.

To find the equation of an ellipse:
