Best ResponseYou've already chosen the best response.0dw:1434247686398:dw You can check if its symmetry by putting in \(\theta\) in \(\theta\) \(r=9cos(5\theta)\) Replacing it, \(r=9cos(5(\theta))\) \(r=9cos(5\theta)\) Can be written as \(9cos(5\theta)=r\) Which means this equation is symmetrical

Best ResponseYou've already chosen the best response.0Thanks for the explanation, but it asks me to say whether is has symmetries, such as symmetry about the polar axis, etc. I know that it does for the polar axis, but need help with the others
