Curve Command
From GeoGebra Manual
- 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.
Note:
- Parametric curves can be used with pre-defined functions and arithmetic operations. For 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 tool New Point or command Point. Since the endpoints a and b are dynamic you can use slider variables as well (see tool Slider).
