[Tugindia] Spacing between lines with mathematical formulae

[Kannan Moudgalya]

Dear All,

I want to create a Table of some mathematical formulae.  I display fractions
using \dfrac command in running text.  Unfortunately, the spacing between
the lines is very little.  Can someone tell me how to increase the line
spacing?
I tried the setspace pacakge, but just the mere inclusion of it in the
usepackage
list increases the number of pages in the document that I am writing - 550
pages
before inclusion and 570 after.

I recall seeing an answer to a similar question in the list. 
Unfortunately, I can not
locate the discussion, even after spending a lot of time in the archive. 
Thanks.

Kannan
