G.5)  Circles

G.5.a)

One way to plot the circle [Graphics:Images/index_gr_1.gif] is: 

[Graphics:Images/index_gr_2.gif]

[Graphics:Images/index_gr_3.gif]

Fairly good results also come from: 

[Graphics:Images/index_gr_4.gif]

[Graphics:Images/index_gr_5.gif]

Another way to plot the circle [Graphics:Images/index_gr_6.gif] is: 

[Graphics:Images/index_gr_7.gif]

[Graphics:Images/index_gr_8.gif]

Now look at: 

[Graphics:Images/index_gr_9.gif]

[Graphics:Images/index_gr_10.gif]

Yuk.
What do you think went wrong?
