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

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.
