A mathematical curve can be defined as a function y = f(x), where x is the coordinate of the horizontal axis and y is the value of the function in that x point. However, not all curves can be defined this way. Parametric equations or functions are a way of defining mathematical curve function of a third variable t called a parameter: \[ \begin ... In kinematics, objects' paths through space are commonly described as parametric curves, with each spatial coordinate depending explicitly on an independent parameter (usually time). Used in this way, the set of parametric equations for the object's coordinates collectively constitute a vector-valued function for position.

Examples 2 and 3 show that different sets of parametric equations can represent the same curve. Thus, we distinguish between a curve, which is a set of points, and a parametric curve,in which the points are traced in a particular way.

A compact version of the parametric equations can be written as follows: Similarly, we can write y(t) = T B z(t) = T C Each dimension is treated independently, so we can deal with curves in any number of dimensions. The derivatives of the curve with respect to t can be expressed as follows: x'(t) = [3t^2 2t 1 0] A Parametric equations are sets of equations in which the Cartesian coordinates are expressed as explicit functions of one or more parameters. For this exploration, we will be primarily considering equations of x and y as functions of a single parameter, t. Parametric Equations. Parametric equations define relations as sets of equations. An image on a graph is said to be parametrized if the set of coordinates (x,y) on the image are represented as functions of a variable, usually t (parametric equations are usually used to represent the motion of an object at any given time t). Match the graphs of the parametric equations x = f ( t ) and y = g ( t ) in (a)–(d) with the parametric curves labeled I–IV.

In this unit we will give examples of curves which are deﬁned in this way, and explain how their rates of change can be found using parametric diﬀerentiation. 2. The parametric deﬁnition of a curve Most algebraic equations lay out a connection like y = x 2. Parametric equations remind us to look deeper (lost on me until recently; I’d been stuck in the “time/physics” mindset).

Parametric Curves General parametric equations We have seen parametric equations for lines. Now we will look at parametric equations of more general trajectories. Repeating what was said earlier, a parametric curve is simply the idea that a point moving in the space traces out a path. We can use a parameter to describe this motion. This section provides an overview of Unit 1, Part C: Parametric Equations for Curves, and links to separate pages for each session containing lecture notes, videos, and other related materials.

In the two-dimensional coordinate system, parametric equations are useful for describing curves that are not necessarily functions. The parameter is an independent variable that both x and y depend on, and as the parameter increases, the values of x and y trace out a path along a plane curve.

This results in two equations, called parametric equations. Let f and g be continuous functions (functions whose graphs are unbroken curves) of the variable t. Let f (t) = x and g(t) = y. These equations are parametric equations, t is the parameter, and the points (f (t), g(t)) make up a plane curve.
