We want to graph the elliptic curve .
First, we create a string that contains the equation we wish to graph.
>> v=’y^2 - x*(x-1)*(x+1)’;
Next we use the ezplot command to plot the elliptic curve.
The plot appears in Figure C.1. The use of in the preceding command is to define the limits of the -axis and -axis in the plot.
Add the points (1,3) and (3,5) on the elliptic curve .
