Hi,

The problem is that postscript don't understand latex macros !
I think you can not insert latex code (\multido) in last psplot arg.
The loop as to be done in postscript 


last psplot :

\psplot[linecolor=blue,plotpoints=400,linewidth=.5pt]{-0.25}{2.25}
       {180 x mul sin 
       %% begin loop
       %% this mean 
       %% for iA=1 to 11 step 2 do 
       %%   iA 180 mul x mul sin iA div add
       %% endfor
       3 2 11 {/iA exch def iA 180 mul x mul sin iA div add} for
       %% end loop
       4 mul 3.14159 div}

PS: faster loop (uses iA on the stack)
       3 2 11 {dup 180 mul x mul sin exch div add} for
