WebMay 22, 2024 · Concave vs. Convex. Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball). If you stand in front of a concave mirror, your reflection will look taller. If you stand in front of a convex mirror, the opposite will happen—your reflection will appear shorter. A unit ball (open or closed) is a ball of radius 1. A subset of a metric space is bounded if it is contained in some ball. A set is totally bounded if, given any positive radius, it is covered by finitely many balls of that radius. The open balls of a metric space can serve as a base, giving this space a topology, the open sets of … See more In mathematics, a ball is the solid figure bounded by a sphere; it is also called a solid sphere. It may be a closed ball (including the boundary points that constitute the sphere) or an open ball (excluding them).
