Hi all,

I want to verify the sum of associated Laguerre polynomials as shown in the picture below. I have tried numerical, but I am struggling with the syntax.

Anyone know how to do that?

Hi,

The black circle below is vanishing at the peak. How do I make the entire  circle visible?

Transparency=0.5 is not a good solution.

Hi all,

I have have s simple graph, see figure below. I want to export it to e.g. PDF-format.

But I want landscape, not portrait. How can I export PDF to landscape?

I tried a workaround: Export it as to JPG gives very bad quality.

I simply want to export my figures to landscape with good quality.

How can I solve this?

Hi all,

How can the black circle be visible?

Visible also below the 3D graph?

Best, perr7

B := spacecurve( [R*cos(t),R*sin(t),0] ,t=0..4*Pi,thickness=1, style=line, color=black);

animate( plot3d, [     P_Pi2(x,y,t)  ,  x=-4000..4000,y=-4000..4000 ], t=0..1, frames=10, transparency=0, style=surfacewireframe, labelfont=[times, roman, 25], orientation=[45,60,0], view=[-4000..4000, -4000..4000, 0..0.006], caption=typeset( theta=Pi/2 ) , axesfont=[times, 15], axes=frame, background=B   );
