d_{x}[ bab[n][a,b,c](x) ] = ...

... (a·x^{2}+b·x·bab[n][a,b,c](x)+c·( bab[n][a,b,c](x) )^{2})/(x+bab[n][a,b,c](x))^{n}

d_{y}[ aba[n][a,b,c](y) ] = ...

... (aba[n][a,b,c](x)+y)^{n}/(a·( aba[n][a,b,c](x) )^{2}+b·aba[n][a,b,c](x)·y+c·y^{2})

d_{x}[ kak[1][a,b](x) ]^{2} = d_{x}[ bab[2][a^{2},2ab,b^{2}](x) ]

d_{y}[ aka[1][a,b](y) ]^{2} = d_{y}[ aba[2][a^{2},2ab,b^{2}](y) ]
