Sum(a[ijk](t)*(x^j)^``(k), `i,j,k`=1..n) + ``(b^j)(t) = 0;

so how do not show the supscribt n?

## both of them,but the number...

both of them,but the number of the points are under control,or random numbers.

but they have a limited condition: they maybe on a circle,they maybe on the vertex of a regular polygon,

the graphics is a simple illustration.that is a try.

the points are in the the cube

The third graph was plotted with default plotpoints,that astonished me

z := x + I*y

ParametricPlot[Through[{Re, Im}[1/z]], {x, 1/4, 1/2}, {y, -2, 2}]

Yesterday I think it should be easier
