Curve[Expression e1, Expression e2, Parameter t, Number a, Number b]: Yields the Cartesian parametric curve for the given x-expression e1 and y-expression e2 (using parameter t) within the given interval [a, b].

Example: Input of c = Curve[2 cos(t), 2 sin(t), t, 0, 2 pi] creates a circle with radius 2 around the origin of the coordinate system.

See Curves for details.

-* Parametric curves can be used with pre-defined functions and arithmetic operations.  For example, input <tt>c(3)</tt> returns the point at parameter position 3 on curve ''c''.
-* Note: Using the mouse you can also place a point on a curve using tool [[New Point Tool|New Point]] or command [[Point Command|Point]]. Since the endpoints ''a'' and ''b'' are dynamic you can use slider variables as well (see tool [[Slider Tool|Slider]]).
