Best ResponseYou've already chosen the best response.0r=r...cos(theta) = 1cos(theta)...2cos(theta)=1...cos(theta)=(1/2)...cos^1(1/2)=pi/3...

Best ResponseYou've already chosen the best response.0the answers are (1/2, pi/3) and (1/2, 5pi/3) Do you basically set them equal to each other then you shall get cos(theta)= 1/2 then just plug the 1/2 back into the r equations?

Best ResponseYou've already chosen the best response.0so its a 60 degree angle and if u go to 360 its also the 300 degree angle?

Best ResponseYou've already chosen the best response.0cos(t) = 1/2 60 and 120 right? but theres a trick about polars if I aint mistaken gotta rotate backwards or something

Best ResponseYou've already chosen the best response.0120 doesn't work cuz then it would be 1/2

Best ResponseYou've already chosen the best response.0sooo the r either way is 1/2 and then its just the 60 and 300 but in radian form??

Best ResponseYou've already chosen the best response.0since r is the same but pi off, there might be more solutions....

Best ResponseYou've already chosen the best response.0well the answer book said what i posted earlier.. and thats what i got.. (mostly double checking with you all)

Best ResponseYou've already chosen the best response.0(1/2,120) would be a solution right?

Best ResponseYou've already chosen the best response.0it cant... since r is positive 1/2 not negative but that is a legit answer if that was needed

Best ResponseYou've already chosen the best response.0same as 240 would be too

Best ResponseYou've already chosen the best response.0polars are tricky because they are defined by more than 1 solution :) unlike cartiseans. but I hear ya ;)

Best ResponseYou've already chosen the best response.0well i got another quick question just like this one... r=cos3(theta) and r = sin3(theta)

anonymous

Best ResponseYou've already chosen the best response.0it's 1/2, pi/3...1/2, pi/5...because cos(pi/3) = 1/2...cos(pi/5) = 1/2...and it keeps going because it's periodic

Best ResponseYou've already chosen the best response.0if you set them eqaul to one another you ill get 1=tan3(theta)

Best ResponseYou've already chosen the best response.0cos and sin are equal at 45 degrees; so I would gander it has to do with muliples of 45/3

Best ResponseYou've already chosen the best response.0actually i have the answers for this too and its (pi/12) (5pi/12) and (9pi/12)
