[CHM 331] The Lineshape Mathematica Problem

[Andrew J. Pounds]

  Okay gang -- I spent some time this morning trying to dissect the 
problems you all were seeing while trying to solve problem 38 on page 
188 of Steiner.   Here is my solution from the competer in my office...

Now -- when I ran it on the computer at my house I got the error many of 
you saw on Friday...

So the problem, if you look at the output in the last problem is that 
Mathematica does not know anything about the variable omega zero.  This 
new version of Mathematica lets us provide more information to the 
integration and solver engines than previous versions of Mathematica.  
We need to tell Mathematica that omega zero is an element of the reals, 
and not an imaginary number.   Way we do this is in then "Assumptions" 
area we provide another argument for omega zero.   Here is what you 
should type -- with the <ESC> being the escape key in the upper left 
hand corner of the keyboard

Assumptions -> { <ESC>omega<ESC>0 <ESC> elem <ESC> Reals, T > 0}]

You should then get something that looks like what I have below.

corrected

I'll send more helpful stuff along later this weekend.
