Troubleshooting a Plot Problem in Mathematica

[Chrescht]

HI,

I've done the following but the plot that I get is not what it has to be at the big values of the frequency f. The graph should be smooth but isn't..

Does somebody know where the problem is?!
The nb file is attached.

Thanks,

Hmmm. Strange - I ran your notebook, and I get a smooth curve. Perhaps your computer is having some pretty severe rounding errors. Kind of strange...

well, today it works fine over here too..but I didn't change anything..I think it simply depends of the Mathematica's mood..couldn't find any other reason

thanks for running the file,

Look at your y-axis!

Check to make sure your values aren't close to machine precision.

As J77 said, look at that y axis, the actual variations in your graph are so small that you can't actually tell what the difference between them is. Looks more like a scale problem, than any problem with mathematica.
