As of this writing, Geogebra has a command ("curve") for plotting parametric curves, but lacks a command for plotting polar functions. One can, however, plot a polar function r = f(0) indirectly - by parametrizing it! Explain why the graph of the parametric equations x(t) = f(t) cost, y(t) = f(t) sint is identical to the graph of the polar function r = f(0). Then use this trick to parametrize the polar equation r = sin(8/2), and graph the result on Geogebra.
