This question already has an answer here:

I want to calculate coordinates for some lines using pstricks. How can I do this?


I want something like

(0.5*cos(45) + 8, 0.5*sin(45) + 8) 

and use coordinate pairs like this one to draw lines in between.

It isn't clear if you want to do the calculation in TeX or PostScript, in PostScript that would be

0.5 45 cos mul 8 add 0.5 45 sin mul 8 add

as you can check by typing to gs (or any other PostScript interpreter):

GS>0.5 45 cos mul 8 add 0.5 45 sin mul 8 add pstack
  • I'm sorry, I want to do the calculations in PostScript, but don't know how to implement it, as \psline(0.5 45 cos mul 8 add,0.5 45 sin mul 8 add)(0,0) isn't working. – MrD Jun 7 '13 at 9:35

    Try \psline(!0.5 45 cos mul 8 add 0.5 45 sin mul 8 add)(0,0). – AlexG Jun 7 '13 at 10:59
