Even here you have to be careful!  I presume you meant

              x
      lim    x   = 1
     x -> 0

?  After all 

              x
      lim    0   = 0
     x -> 0

And strictly speaking, the "x -> 0"s should be "x -> 0+"s...

Anything else you want me to be anal about today?  I have to start
tutoring undergrads in this sort of thing fairly soon, so it's
probably good to get some practice...

Cheers,
M.
