Homework Help: Pre-Calc

Posted by Thomas on Saturday, September 24, 2011 at 4:34pm.

Can anyone direct me to learn more about polar coordinates. I'm in online college course and really am confused. In high school, I never heard of polar coordinates.
Like they say is the following the graph of point (3,15) and show it on polar grid-I don't get it at all. Please direct me somewhere to learn this or can you give me any easy explanation-thank you
