It's been a long time since I've touched Math, and now I'm taking a Calculus course.. can anyone refresh my memory on how I would solve the following expression?
.. 1 ........... 1
------ .. - .. ---
a + h ........ a
----------------
........h........
or (( 1 / a + h) - ( 1 / a)) / h
a != 0
The limit is h-> 0. I can figure it out once I simplify the expression, but I forget how to deal with the 1 / stuff....
Edit:
