Next we will graph another special plane curve, called a Lissajous figure, defined by the parametric equations  . Enter the
functions in the function editor.
The sine function has an amplitude of 3, so we will set the WINDOW so that |

. The cosine function has an amplitude
of 2, so we will set 
. The period
of the sine function is π, and the period of the cosine function is π/5. The least
common multiple of these periods is 2π, so we will set 
and let Tstep = 0.1.
