**Conic optimization**— is a subfield of convex optimization that studies a class of structured convex optimization problems called conic optimization problems. A conic optimization problem consists of minimizing a convex function over the intersection of an affine… …2

**Conic section**— Types of conic sections: 1. Parabola 2. Circle and ellipse 3. Hyperbola …3

**Degenerate conic**— Main article: Conic section In mathematics, a degenerate conic is a conic (degree 2 plane curve, the zeros of a degree 2 polynomial equation, a quadratic) that fails to be an irreducible curve. This can happen in two ways: either it is a… …4

**Dandelin spheres**— are touching the light blue plane that intersects the cone. In geometry, the Dandelin spheres are one or two spheres that are tangent both to a plane and to a cone that intersects the plane. The intersection of the cone and the plane is a conic… …5
