and describes points in K2, the Cartesian product of K with itself. If the field's characteristic is different from 2 and 3, then thecurve can be described...
such curves has singular points (see Genus–degree formula). A non-plane curve is often called a space curve or a skew curve. An algebraic curve in the Euclidean...
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints...
in the study of elliptic curves is devising effective ways of counting pointsonthecurve. There have been several approaches to do so, and the algorithms...
the type of curve being studied. Algebraic curves in the plane may be defined as the set of points (x, y) satisfying an equation of the form f ( x ,...
defined it as the line through a pair of infinitely close pointsonthecurve. More precisely, a straight line is tangent to thecurve y = f(x) at a point...
(known as the elliptic curve discrete logarithm problem by analogy to other cryptographic systems). This is because the addition of two pointson an elliptic...
In microeconomics, the contract curve or Pareto set is the set of points representing final allocations of two goods between two people that could occur...
computing the large numbers of points required for a detailed plot. It is an application of the theory of curves to find their main features. The following...
point on a smooth plane curve at which the curvature changes sign. In particular, in the case of the graph of a function, it is a point where the function...
smooth curves of varying radii. Thecurve is placed onthe drawing material, and a pencil, knife or other implement is traced around its curves to produce...
used to express the coordinates of thepoints that make up a geometric object such as a curve or surface, called a parametric curve and parametric surface...
connecting up the geometries of pointson a curve — is tantamount to providing a connection. In fact, the usual notion of connection is the infinitesimal...
cubic curve through any nine given points, which may be degenerate, and may not be unique, but will be unique and non-degenerate if thepoints are in...
more variables, and the interval of integration is replaced by a curve connecting two points in space. In a surface integral, thecurve is replaced by a...
plane curve at a given point p onthecurve has been traditionally defined as the circle passing through p and a pair of additional pointsonthecurve infinitesimally...
In economics, an indifference curve connects pointson a graph representing different quantities of two goods, points between which a consumer is indifferent...
