Abstract AR
الهدف من هذا البحث هو اعطاء صيغة معممة جديدة لتعريف الغلاف و ذلك بإعطاء تعريف غير قياسي للغلاف عائلة من المستقيمات معرفة في إحداثيات الاسقاطية المتجانسة بواسطة : u(t)x+ v(t)y w(t)z = : 0 و كذلك تم تطبيق التعريف الجديد على منحنيات المخطروطية و ذلك بالبحث عن معادلة عائلة المنحنيات التي يكون غلافها منحنيا مخطروطيا معروفا.
Abstract EN
The generalized envelopes are studied by a given nonstandard definition of envelope of a family of lines defined in a projective homogenous coordinates PHC by: u(t) x + v(t) y + w(t) z = 0.
The new nonstandard concepts of envelope are applied to conic sections.
Our goal in this paper is hat for a given conic section curve f(x, y) = 0, we search for the family of lines in which f is its envelope.
