WebJul 25, 2024 · Among all representations of a curve there is a "simplest" one. If the particle travels at the constant rate of one unit per second, then we say that the curve is parameterized by arc length. We have seen this concept before in the definition of radians. On a unit circle one radian is one unit of arc length around the circle. WebThe parametric curve is defined by its corresponding parametric equations: x = f ( t) and y = g ( t) within a given interval.

The graph of parametric equations is called a parametric curve or plane curve, and is denoted by C. Notice in this definition that x and y are used in two ways. WebDec 28, 2024 · theorem 82 arc length of parametric curves Let x=f (t) and y=g (t) be parametric equations with f^\prime and g^\prime continuous on some open interval I containing t_1 and t_2 on which the graph traces itself only once. The arc length of the graph, from t=t_1 to t=t_2, is L = \int_ {t_1}^ {t_2} \sqrt {f^\prime (t)^2+g^\prime (t)^2}\ dt. WebSep 11, 2024 · In fact, a curve y = f(x) is the special case where the parametric equations are x = t and y = f(t). In physical settings the parameter t often denotes time, but it can represent anything and any symbol can be used in its place. A curve can have many parametrizations.
