In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a moving point. This is the definition that appeared more than 2000 years ago in Euclid's Elements: "The [curved] line is […] the … Meer weergeven Interest in curves began long before they were the subject of mathematical study. This can be seen in numerous examples of their decorative use in art and on everyday objects dating back to prehistoric times. … Meer weergeven Roughly speaking a differentiable curve is a curve that is defined as being locally the image of an injective differentiable function $${\displaystyle \gamma \colon I\rightarrow X}$$ from an interval I of the real numbers into a differentiable manifold X, often Meer weergeven • Coordinate curve • Crinkled arc • Curve fitting • Curve orientation • Curve sketching • Differential geometry of curves Meer weergeven A topological curve can be specified by a continuous function $${\displaystyle \gamma \colon I\rightarrow X}$$ from an interval I of the real numbers into a topological space Meer weergeven Algebraic curves are the curves considered in algebraic geometry. A plane algebraic curve is the set of the points of coordinates x, y such that f(x, y) = 0, where f is a polynomial in two variables defined over some field F.
