Polar curves absolutely drives me nuts. I can do the integration to find the area of it no problem. The problem is.. I don't know the limits of the integration is! Sometimes is from 0 to [tex]\pi [/tex] other times it is from 0 to [tex]2\pi[/tex]..(adsbygoogle = window.adsbygoogle || []).push({});

Is there no other way but to graph the curve out? Believe me, if I have time I would sketch out the curve but in my calc exams, every second counts. They literally swarm us with questions and our goal is to solve as many as possible and hope the curve carry us up. Is there no faster way? If graph it out is the only way to do it, I will practice it but I am just curious to see if there is any other tricks out there. Thanks.
