Now we will graph Γ, which is a parametric curve.
In the Equation Writer, type
X(t) + i × Y(t).
Select the entire expression
and press 
.
Now press 
, select Parametric and press 
. Select X1,Y1 as the destination and press 
.
To make the graph of Γ, quit CAS and choose the Parametric aplet. Check X1(T) and Y1(T).
Now press 
to see the graph.
