(a) the cartesian coordinates of a point in the xy-plane are (x, y) polar coordinates of this point. (-3.11, -2.05) m. find the r3.724 m e=-33.4x your response differs from the correct answer by more than 10%. double check your calculations. (b) convert (r, e) = (4.86 m, 38.70) to rectangular coordinates. y= exercise hints getting started i'm stuck! (a) find the polar coordinates corresponding to (x, y) = (3.1, 1.63) m. 3.50 m (b) find the cartesian coordinates corresponding to (r, e) (4.2 m, 59°).
