Best ResponseYou've already chosen the best response.0so where does the (2, pi/3) come in?

Best ResponseYou've already chosen the best response.0cos(60) = 1/2 ; sin(60) = sqrt(3)/2

Best ResponseYou've already chosen the best response.02cos(60) = 2(1/2) = 1 ; x = 1 2sin(60) = 2(sqrt(3)/2) = sqrt(3) ; y = sqrt(3)

Best ResponseYou've already chosen the best response.0why doesn't x = 2 and y = pi/3

Best ResponseYou've already chosen the best response.0those would be the rectanglular plots for the point. otherwise, you just turn the required degrees and move out the required distance

Best ResponseYou've already chosen the best response.0since r = 2 and cos(60) = 1/2 2(1/2) = 1

Best ResponseYou've already chosen the best response.0polar coordinates can have many names for the same spot...

Best ResponseYou've already chosen the best response.0you can turn the required degrees, or turn in the opposite direction till you get to the spot, you can rutn 180 degrees less and just walk backwards to get there...etc

Best ResponseYou've already chosen the best response.0rutn is some stroke version of turn :)
