Ares Posted April 27, 2004 Report Share Posted April 27, 2004 Helloi just reviewed in my calc class polar coordinates and the fact that some problems such as r=4cos 2(theta) (this equation may be wrong its suppose to be a circle don't have the book on me or a grapher) and r=Pi/3 only have one mathimatical intersection however when graph they clearly have 2. This really is bothering me that it doesn't make sence and that something else must be left out. I understand that a point may have a infinite amount of coordinates for it but it just doesn't quite make sence why only a finite work and seems that even fewer if any work out mathimatically. Hope that made some sence at what i am trying to get at.______________________________________p.s. I love this site just found it a few days ago.

Gill_105 Posted April 28, 2004 Report Share Posted April 28, 2004 I dont understand you either... But I do know that 4*cos(2*theta) sure as hell doesn't graph a circle. Link to comment Share on other sites More sharing options...
