Could you post us an expression that we can read and copy? One without the
question marks. You can convert your cell to InputForm, then copy that and
paste it into the posting.

I have the following solution to a Fourier Transform problem

2/Pi*Integrate[Cos[?]/?^2*(1 - Exp[-?^2*t])*Cos[?*x], {?, 0, ?}]

I need to plot it for t =0,1,2,3,4,5  and 0 < x< 5 in Mathematica, but
the program can evaluate the integral

Is there a way to numerically get the program to plot it??
