I am terribly sorry,but I simply could not get it at all.I think I can easily find the horizontal,vertical and oblique asymptotes of the cartesian curve but I just don't have any concept regarding of finding asymptotes of the polar curve.Please explain it to me from the scratch.

What part of the discussion do you not understand? Do oyu know how to solve a trigometric equation such as ?

It may be that you're weak in the mathematical background assumed for these sorts of problems. In which case you're best advised to go back and revise the prerequisite mathematical concepts. - Aug 23rd 2008, 05:35 AMroshanhero
We have been teached to find the asymptotes of polar curve by using formula-

Rsin(q -a )=1/f'(a )

Where a denotes the roots of f (q )=0

I appiled it but failed.

Can we show me how to do it by using this formula.
