Hi Amer,what is the best way to graph in polar coordinates say

[tex]r = 3 - 5 \cos \theta [/tex]

is it to plot several points then make a curve between them or ?

Unless the curve given is a standard curve (circle, ellipse etc) or can be transformed into a standard form, we have to plot it by marking points. I drew your curve using Maxima.
