Find parametric equations for the set of all pointsPas shown in the figure, wherea=2, such that |OP| = |AB|. (This curve is called thecissoid of Dioclesafter the Greek scholar Diocles, who introduced the cissoid as a graphical method for constructing the edge of a cube whose volume is twice that of a given cube. Enter your answer as a comma-separated list of equations. Letxandybe in terms of?.)
