    we gotta figure out where we end up..thats all :) normally, when the "r" is a positive number, we spin around by the angle and walk forward by "r" steps

    polar coordinates give us two bits of information; how far to rotate(11pi/2) and how far to move(-2); where we end up is how we figure the (x,y) point for rectangular coordinates

    teh x,y equivalent for this should be (0,2)

    11pi/2 rotates us till we are pointing due south...straight down. then we back up 2 steps..... we simply end up at (0,2)
