Ellipse, arc of ellipse and elliptic spline
Computers & Graphics, 1983Abstract A general method for generating ellipses by using conjugate radii is presented. Elliptical arcs are then defined based on this method for generating ellipses. A 90° arc of ellipse is then used to generate a number of curves with slope constraints. Other arc of ellipse interpolations are then discussed.

Die Ellipse als Kreisprojektion. Fläche der Ellipse
1925Es liege eine Ellipse und der grose Scheitelkreis gezeichnet vor. Nach § 40 Gl. (1) ist \(PC = \frac{b}{a} \cdot QC\). Denken wir uns nun den Scheitelkreis aus der Papierebene, der Ebene der Ellipse, um den Durchmesser A 1 A 2 herausgedreht, bis der Punkt D senkrecht uber B 1 liegt, dann liegt jeder andere Kreispunkt genau senkrecht uber oder unter dem

Ellipse & fragment. Morceaux choisis
2013L'histoire de la linguistique est traversée de plusieurs courants qui se sont intéressés à des énoncés "incomplets", traités tantôt comme "elliptiques", tantôt comme "fragmentaires", selon le rapport que l'on établit ou non avec des structures sous-jacentes " canoniques ".

Abstract Ellipses fill the void when writers take a word or phrase out of the middle or end of a quote. In our online world, cutting and pasting is so easy that plenty of lawyers overload their writing with quotations. The justices do not. When they do insert a quote, they make sure every word is necessary.
