[l2h] A sum in the denominator of a fraction didn't lookquite normal.

[Pat Somerville]

Thanks, Dr. or Mr. Shigeharu Takeno, for kindly taking the time to add your 
points, particularly on how to use \displaystyle in the math mode in LaTeX. 
I think Thorsten may have mentioned using displaystyle as another solution 
to my sort of problem in the LaTeX-community Internet posting of someone 
else to which I earlier referred.  With your example it is good to see how 
to use \displaystyle in the math mode.

Sorry, earlier in this chain of e-mail letters I used the words "partly 
imaginary" in a way that might have been ambiguous for some people.  I 
should have instead used something unambiguous like "partly made-up;" 
"imaginary" could have meant something times the square root of negative 
one, which I did not mean.
