Rotation (mathematics) — Rotation of an object in two dimensions around a point O. In geometry and linear algebra, a rotation is a transformation in a plane or in space that describes the motion of a rigid body around a fixed point. A rotation is different from a… … Wikipedia
Rotation of axes — is a form of Euclidean transformation in which the entire xy coordinate system is rotated in the counter clockwise direction with respect to the origin (0, 0) through a scalar quantity denoted by θ.With the exception of the degenerate cases, if a … Wikipedia
Rotation matrix — In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian… … Wikipedia
Degree (angle) — One degree (shown in red) and ninety degrees (shown in blue) This article describes the unit of angle. For other meanings and some specific usages, see degree. A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by °… … Wikipedia
Rotation representation (mathematics) — In geometry a rotation representation expresses the orientation of an object (or coordinate frame) relative to a coordinate reference frame. This concept extends to classical mechanics where rotational (or angular) kinematics is the science of… … Wikipedia
Rotation around a fixed axis — Rotational motion can occur around more than one axis at once, and can involve phenomena such as wobbling and precession. Rotation around a fixed axis is a special case of rotational motion, which does not involve those phenomena. The kinematics… … Wikipedia
Rotation system — In combinatorial mathematics, rotation systems encode embeddings of graphs onto orientable surfaces, by describing the circular ordering of a graph s edges around each vertex.A more formal definition of a rotation system involves pairs of… … Wikipedia
Rotation number — This article is about the rotation number, which is sometimes called the map winding number or simply winding number. There is another meaning for winding number, which appears in complex analysis. In mathematics, the rotation number is an… … Wikipedia
degree of freedom — in the simplest of cases, a degree of freedom is an independent displacement or rotation that a system may exhibit. A degree of freedom for a system is analogous to an independent variable for a mathematical function. All system degrees of… … Mechanics glossary
degree of freedom — noun 1. Statistics the number of independent random variables that together make up a statistic. 2. a. Mechanics the number of independent ways a body can be displaced. b. Physics the number of independent ways in which a molecule can possess… …
