Thank you.

**Count Iblis**, Monday, September 15, 2008 at 10:17amSubstitute x = 1 - t and expand the squareroots in series using the formula:

sqrt[1 + y] = 1 + y/2 + O(y^2)

You should then find that the limit is 1/2

Multiply by ((5-X)^.5 + 2)/((5-X)^.5 + 2)*((2-X)^.5 + 1)/((2-X)^.5 + 1)

which reduces your question to

Limit ((2-X)^.5 + 1)/((5-X)^.5 + 2) as x-->1

= 2/4

= 1/2

BTW, it is strongly suggested that you do not put your email or personal information in these postings
