I've been having a problem finding the intersection points of the following polar equations. r=1+3sin(theta) and r=1-3cos(theta) Now I've set the equations equal to each other to obtain those points. I've set each equation equal to zero. The problem I'm having is that when graphed, there are intersection points that can't be found due to each graph passing through the respective point at a different angle. I was wondering if anyone could tell me how I would go about finding those intersection points; I need these points in order to find certain areas of the graph. It would be of MASSIVE help if anyone could provide me with information. Thank you.
