In Problems 3542, plot each point given in polar coordinates, and find other polar coordinates (r, ) of the point for which: (a) r> 0,

In Problems 35–42, plot each point given in polar coordinates, and find other polar coordinates (r, θ) of the point for which:

(a) r> 0, -2 0 < 0 (b) r < 0, 0 0 < 2 (c) r> 0, 2 0 < 4T
