- 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.
- 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.
- Notes:
- End Value must be greater than or equal to Start Value and both must be finite.
- x, y and z are not allowed as parameter variables.
- See Curves for details, also see the Derivative Command and the Parametric Derivative Command.
