Basically, consider 1.999999999999 What is the GIF value of that?

1

now , c-h just meant (c-1)+0.999999.... Right? So what happens when you take the GIF value?

Ok, so basically, h is a small value that is tending to zero, right?

Take and actual value, say, 0.000000001 *an And let c also be some number Say, 5

c-h, for all non-zero values of h, as long as it isn't zero, i.e. in the limiting case will always be 4.99999 something

i understand now

So, take the GIF You always get 4
putangina

cause even if h was the smallest value imaginable, it would cause c-1 because of GIF

It's different once h hits 0, and then you get 5, but we don't care. We just want the left hand side limit. Bingo.
