Curves
From GeoGebra Manual
There are two types of curves in GeoGebra.
Parametric curves
Parametric curves of the form a(t)=(f(t),g(t)) where t is real parameter within certain range can be created using the Curve Command. They can be used in Tangent Command and Point Command.
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. - 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).
Creating parametric curve going through given points is not possible. You can however try e.g. FitPoly Command to get a function going through these points.
Implicit curves
Implicit curves are polynomials in variables x and y. The can be entered directly into Input Bar.
Example: x^4+y^3=2x*y
