It's best to use a polar graph to plot the points

3. blackstreet23

umm I think i might know what i have to do

4. blackstreet23

but i just dont know is that is right

5. blackstreet23

I mean i trying to find the endpoints to just draw a rought sketch

6. blackstreet23

I got that $r = +or- (r*\sqrt{2\sin(\theta)}$

7. blackstreet23

sorry 4

8. blackstreet23

4 * root(sin2(theta))

9. blackstreet23

?

The graph is the same for both positive and negative expressions
