[pstricks] rotated vector in pstricks

[Juergen Gilg]

Dear Ziggy,

there is another nice way to do the same -- try

\rput(0,0.5){\psline(0,0)(0.25;45)}

Now if you separate coordinates with a ";" instead of a "," -- this 
tells PSTricks to use POLAR COORDINATES (Radius;Angle with positive 
x-axis) instead of (x,y)

Very helpful for lines with a given length and angle with the horizontal 
starting in the origin.

Just as a little addition.

Regards,

Jürgen
