   Is a polygon convex or concave?

   • Classify these polygons as convex, concave, or neither. We begin with polygon A. All of its angles are less than 180^\circ 180∘, so it is a convex polygon. Polygon B has two sides which intersect, so it is a self-intersecting polygon, not a simple polygon. Therefore, it cannot be convex or concave, so it is neither.

   What is a convex polygon?

   • A convex polygon is a simple polygon that has all its interior angles less than 180^\circ 180∘ As opposed to a convex polygon, a concave polygon is a simple polygon that has at least one interior angle greater than 180^\circ 180∘. Classify these polygons as convex, concave, or neither. We begin with polygon A.

   Is a spherical mirror concave or convex?

   • The incident ray, the reflected ray and the normal at the point of incidence all lie on the same plane. The angle of incidence is always equal to the angle of reflection. Spherical mirrors are classified as concave when the reflecting surface is curved inward and convex when the reflecting surface is curved outward.

   3 days ago · The likelihood function (often simply called the likelihood) is the joint probability mass (or probability density) of observed data viewed as a function of the parameters of a statistical model. [1] [2] [3] Intuitively, the likelihood function is the probability of observing data assuming is the actual parameter.

   5 days ago · Mirrors, unlike lenses, are not transparent materials, but instead are polished surfaces that reflect incoming light rays. Mirrors can be plane (flat) or spherical (curved). Spherical mirrors are classified as concave when the reflecting surface is curved inward and convex when the reflecting surface is curved outward.

   3 days ago · Convex-concave programming is an organized heuristic for solving nonconvex problems that involve objective and constraint functions that are a sum of a convex and a concave term. DCP is a structured way to define convex optimization problems, based on a family of basic convex and concave functions and a few rules for combining them.
