curvature

listen to the pronunciation of curvature
الإنجليزية - الإنجليزية
The extent to which a subspace is curved within a metric space
The shape of something curved
The extent to which a Riemannian manifold is intrinsically curved
{n} a crookedness, a bend, a winding
the rate of change (at a point) of the angle between a curve and a tangent to the curve
The curvature of something is its curved shape, especially when this shape is part of the circumference of a circle. the curvature of the earth. the state of being curved, or the degree to which something is curved curvature of (curvatura, from curvare; CURVE). Measure of the rate of change of direction of a curved line or surface at any point. In general, it is the reciprocal of the radius of the circle or sphere of best fit to the curve or surface at that point. This notion of best fit derives from the principle that only one circle can be drawn though any three points not on the same line. The radius of curvature at the middle point is approximately equal to the radius of that one circle. This calculation becomes more exact the closer the points are. The precise value is found using a limit. Because a straight line can be thought of as an arc of a circle of infinite radius, its curvature is zero
the property possessed by the curving of a line or surface the rate of change (at a point) of the angle between a curve and a tangent to the curve (medicine) a curving or bending; often abnormal; "curvature of the spine

The act of curving or bending One of the characteristics of line
The amount of degree of bending of a mathematical curve, or the tendency at any point to depart from a tangent drawn to the curve at that point
In Riemannian geometry, usually means the intrinsic curvature of a manifold with a Riemannian metric The curvature at a point is positive (negative) if the sum of the angles of a small approximate triangle at that point is greater than (less than) 180 degrees
The act of curving, or the state of being bent or curved; a curving or bending, normal or abnormal, as of a line or surface from a rectilinear direction; a bend; a curve
{i} act of curving, state of being curved; measure of the degree of a curve in a line
Let C be a curve and let P be a point on C Let N be the normal at P and let O be the point on N which is the limit of where the normal to C at P' intersects N as P' tends to P O is the centre of curvature at P and PO is the radius of curvature at that point
the degree of curving of a line or surface
The rotation per unit length of a member due to bending forces
(medicine) a curving or bending; often abnormal; "curvature of the spine"
the property possessed by the curving of a line or surface
Mathematically, is the second derivative of terrain elevation Is an important feature in shape analysis and is used to indicate convexity/concavity of a surface
