And if ( r , u ) is a solution, so is ( r , 2 u ). Therefore, the curve is symmetric about the xaxis. And since any curve with xaxis and origin symmetry also has yaxis symmetry, the curve is symmetric about the yaxis. 60. If ( r , u ) is a solution, so is ( 2 r , u ). Therefore, the curve is symmetric about the origin. The curve does not have xaxis or yaxis symmetry. 6 cos u 2 2 sin u 6 ˇ (6 w c w o w s w u w 2 w 2 w s w in w u w ) 2 w 2 w 2 w 4 w }}}}} 2 424 Section 10.5...
