Dear All -

if memory serves me right, the intersection curve of
a cone with a cylinder (like in a powder diffraction camera) is
not an ellipse, but a "Schnittfigur zweiter Ordnung",
loosly translated as 'intersection curve of second order'.

Is there a correct English term for that type of curve?

Thx, br
