You have run all the lines together. The actual code is

set xtics ('$-\pi$' -pi,\
'$-\frac{\pi}{2}$' -pi/2,\
"0" 0,\
'$\frac{\pi}{2}$' pi/2,\
'$\pi$' pi)

The backslashes at the end of those lines say to ignore 
the end-of-line. If you run all these together as a 
single line you have to remove the backslashes.

In your code, a \' indicates that ' should be taken literally
and not as a quote to start a string. This is probably where
gnuplot noted an error.
