what about this one?
The graph of a limacon curve is given. Without using your graphing calculator, determine which equation is correct for the graph

anonymous · Answer

[-5, 5] by [-5, 5]

agent0smith · Answer

^I think i'd need the graph.. if you have a book, it should have some general equation forms.

anonymous · Answer

r = 2 + 2 sin θ

 r = 3 + sin θ

 r = 1 + 3 cos θ

 r = 1 + 3 sin θ

agent0smith · Answer

You could graph each and see which matches, cos i can't tell...
