Curve[expression e1, expression e2, parameter t, number a, number b]: Cartesian parametric curve for the given x-expression e1 and y-expression e2 (using parameter t) within the given interval [a, b]
Example: c = Curve[2 cos(t), 2 sin(t), t, 0, 2 pi]
Derivative[curve c]: Derivative of the curve c
Note: Parametric curves can be used like functions in arithmetic expressions.
Example: Input c(3) returns the point at parameter position 3 on curve c.
Note: Using
the mouse you can also place a point on a curve using the mode New point (see mode New point; also see command Point).
Since the parameters a and b are dynamic you could use slider
variables there (see mode Slider).
