Functions
- measure of the half-axis of an ellipse
- measure the circumfence of an ellipse
- measure the area of an ellipse
Description
With this measure instrument, you can measure, the half-axis, the
circumfence and the area of an ellipse.
By moving the focal points and the point on> the ellipse
you can modify the ellipse.
Moving the point between the two focal points will move the
complete ellipse.
