91Y-intercept — In coordinate geometry, the y intercept is the y value of the point where the graph of a function or relation intercepts the y axis of the coordinate system. In other words, the y intercept of a function is the y value of the point at which it… …
92Three-dimensional space — is a geometric model of the physical universe in which we live. The three dimensions are commonly called length, width, and depth (or height), although any three mutually perpendicular directions can serve as the three dimensions. A three… …
93Minimum bounding box — The minimum or smallest bounding or enclosing box for a point set in N dimensions is the box with the smallest measure (area, volume, or hypervolume in higher dimensions) within which all the points lie. When other kinds of measure are used, the… …
94isometric drawing — also called isometric projection method of graphic representation of three dimensional objects, used by engineers, technical illustrators, and, occasionally, architects. The technique is intended to combine the illusion of depth, as in a… …
95Trammel of Archimedes — Trammel of Archimedes. A trammel of Archimedes is a mechanism that traces out an ellipse.[1] It consists of two shuttles which are confined ( trammelled ) to perpendicular channels or rails, and a rod which is attached to the shuttles by pivo …
96hyperbolic paraboloid — noun Date: 1842 a saddle shaped quadric surface whose sections by planes parallel to one coordinate plane are hyperbolas while those sections by planes parallel to the other two are parabolas if proper orientation of the coordinate axes is… …
97Constructible number — For numbers constructible in the sense of set theory, see Constructible universe. A point in the Euclidean plane is a constructible point if, given a fixed coordinate system (or a fixed line segment of unit length), the point can be constructed… …
98Octahedron — For the album by The Mars Volta, see Octahedron (album). Regular Octahedron (Click here for rotating model) Type Platonic solid Elements F = 8, E = 12 V = 6 (χ = 2) Faces by sides …
99Interval (mathematics) — This article is about intervals of real numbers. For intervals in general mathematics, see Partially ordered set. For other uses, see Interval. In mathematics, a (real) interval is a set of real numbers with the property that any number that lies …
100Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …
