Plot the point 1. given in polar coordinates, and find other polar coordinatos (r.0) of the point for which the following are true. (a) r>0,-2x SO<0 (b) r<0, 0 s0< 2n (c) r>0, 2x s0< 4x (a) What are the coordinates of the point for which r>0,-2ns0<0? (Type an ordered pair. Type an exact answer using x as needed. Use integers or fractions for any numbers in the expression. Simplify your answer.) (b) What are the coordinates of the point for which r<0, 0s0<2? (Type an ordered pair. Type an oxact answer using x as needed. Use integers or fractions for any numbers in the expression. Simplity your answer) (c) What are the coordinates of the point for which r>0, 2n s0<4x? (Type an ordered pair. Type an exact answer using n as needed. Use integers or fractions for any numbers in the expression. Cimplid UDUE aneitiar Y
