hi every one

I need to rearrange the matrix variables after using collect command

R[3, 3] := collect(R[3, 3], z^2);
                                  2             
               (-cos(theta) + 1) z  + cos(theta)
sort(R[3, 3]);
                                  2             
               (-cos(theta) + 1) z  + cos(theta)

i want it to appear as z(1-cos(theta))+cos(theta) ,  can i use sort or sequence or there is another command to do this   ???

hi every one

 im new in maple, i have this problem , the output result (nod) dont disply after the for loop how can i disply it ?( sorry for this question, im new in this prog.)

the 2nd question is the (Typesetting:-delayDotProduct) how can i resolve this???

plz help 

for i from 2 to 3 do for j from 2 to 3 do Typesetting[delayDotProduct](rod, [i, j], true) := s*imp*l*i*f*y*subs*({cx^2 = 1-cy^2-cz^2}, Typesetting[delayDotProduct](rod, [i, j], true)) end do end do;
Typesetting[delayDotProduct](rod, [1, 1], true) := collect(rod[1, 1], cos(theta));
