after solving a long diff question i got

0.5*u(t+1)-0.5*u(t-1)

where u(t) is a step function for t>=0 its 1

and t<0 its 0

my expression looks pretty finite to me

how to continue??

Could you furnish the original question?

It appears the original DE is non-homogeneous with the forcing term

involving delta functions?
