Hi all, I write for a little help, I have the function

y^2 = x and I turned it to its polar form by the following steps

    ini = y^2 == x /. {x -> r*Cos[x], y -> r*Sin[x]} ;
    conv = Replace[r, Solve[ini, r]][[2]];
PolarPlot[Cot[t] Csc[t], {t, 0, 2 Pi}, 
 PlotRange -> {{0, 80}, {-10, 10}}]

Then attempt to convert it to its form parametric from the polar form but the plot is where the problem arises

conv*Cos[x] (* This is x[t]*)
conv*Sin[x]   (* This is y[t]*)

The problem is the graph the equations parametric I have obtained, someone could tell me please do that I'm doing wrong?

ParametricPlot[{Cot[t]^2, Cot[t]}, {t, 0, 2 Pi}]

Thanks in advance.
