Hi all,

I've posted a few questions tonight, last one I promise.

I'm trying to graph polar coordinates and understand how to do it with r = blah blah, and that gives your distance at the set angle.

I've been given the equation to graph however, and I've got no idea to be honest. Obviously I could rearrange to make theta the subject (equals +/- square root of 1) but still don't see how that fits onto the circular graph.

How do I find the values of r?

Cheers.
