- Curve[ <Expression a>, <Expression b>, <Parameter Variable>, <Start Value>, <End Value> ]
- Yields the Cartesian parametric curve for the given x-expression a and y-expression b (using parameter variable) within the given interval [Start Value, End Value].
- Example:
Curve[2 cos(t), 2 sin(t), t, 0, 2π]
creates a circle with radius 2 around the origin of the coordinate system.
- Note:
- End Value must be greater than or equal to Start Value and both must be finite.
- x is not allowed as a parameter variable.
Note: See Curves for details, also see the Derivative Command and the Parametric Derivative Command.
