There is no built-in way to fill the area, but you can quickly write your own hatch function to create a number of vertical hatch lines between two functions:

MC15 sheet attached

BTW, I'm a bit irritated because I am not able to resize the plot region, making it smaller. Not sure why!?

      You may consider renaming your function to hatch_aux(f,g,...) and define

      hatch(f,g,x1,x2,n):=hatch_aux(f,g,x1,x2,n,n)

       

      That way you avoid having to provide the number of lines (n) twice.
