Updated. The document can not be saved. I don't know why.

plot([`in`[1], `in`[2], t=0..2*Pi], color=blue );

plot3d( `in`, x=-5..5, y=-5..5, scaling=constrained, style=patch,

lightmodel=`light4`, projection=`normal`, shading=zgrayscale );

F:=implicitplot3d( `in`[1]=0, x=-2..2, y=-2..2, z=-2..2, grid=[30,30,30],

Aha,...convert() was the magic word. Thank you
Strange, but this one was the only one successful



My other attempts in making plots and reproducing your pictures, issued an error about missing gif file in tmp folder. See the picture please



The problem of not saving pictures and SMat crash still remained.

Here it is. If you want me something in particular to try, just let me know.

Radovan, you have to change the maple-commands for each graph. In your example these commands are set incorrectly. I specifically show the commands. They need to be inserted into the settings form, as showed above.

1) Try this:

a := plot( `in`, t=0..20, x=-1.5..1.5, scaling=unconstrained, style=line,
color=blue, axes=box, labels=["t","x(t) "]):

b := coordplot(rectangular, [0..20, -1.5..1.5], linestyle=[7,7],
color=[gray,gray]):

display([a,b]);

2) projection=`normal must be projection=`normal`

Try to add with(plots): to with.inc:

Nice

Just to confirm. The EMPTY PLOT is now working fine. No crash of SMath at the plot inserting

I do not use maple to much (it is interesting and a fun using it in SMath ) , and someone else might give you a better solution - but this should work

e1a^2-1)*1/sqrt(a)

e2b-1)*(b+1)/sqrt(

maple(simplify(subs(a≡b,e1)-e2))=0

Updated. Still can't save region.

In your example:
`in`x^2+y^2+z^2)-1

but expected:

sys(el(`in`;1);el(`in`;2);2;1):sys((x^2+y^2+z^2)-1;0;2;1)

we get: `in`[1]="" , `in`[2]="" - empty values (because it is not a system) and `in`=(x^2+y^2+z^2)-1 (but is missing in script)

Must be:




This is normal.
