- Curve[ <Expression>, <Expression>, <Parameter Variable>, <Start Value>, <End Value> ]
- Yields the Cartesian parametric curve for the given x-expression (first <Expression>) and y-expression (second <Expression>) (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.
- Curve[ <Expression> , <Expression> , <Expression> , <Parameter Variable> , <Start Value> , <End Value> ]
- Yields the 3D Cartesian parametric curve for the given x-expression (first <Expression>), y-expression (second <Expression>) and z-expression (third <Expression>) (using parameter variable) within the given interval [Start Value, End Value].
- Example:
Curve[cos(t), sin(t), t, t, 0, 10π]creates a 3D spiral.
