Graphing Parametric Equations with GeoGebra

GeoGebra gives us a convenient way to graph a set of parametric equations. By creating a slider for the variable t and inputting our functions as the x and y coordinates of a point, we can see how that point moves as the slider varies. We also need to keep in mind why we get the graph that we do. By investigating what algebraic relationship the coordinate functions fit into, we can understand what the graph will be.
