Identify the polar coordinates for each value in the table below and use this to graph the equation of r=3sin 20 Symmetry hint: see if the equation is true for the following: the line 0 = 90: replace ( r, 0) with (r, 180 - 0) or (-r, -9) the polar axis: replace ( r. 0) with (-r, 180' - 0) or (r, -8) the pole: replace ( r, 0) with (r, 180' + 0) or (-r, 0)
