I like to just think of the limit definition of the derivative, may i should write out.
00:06
F prime of x is equal to the limit as h approaches zero of f of x minus f of x plus h minus f of x all over h.
00:23
So if you look at part a where they write out the limit as h approaches zero of e to the h minus 1 all over, i think actually what i have is the alternate form of the derivative.
00:44
There's another form where it's like the limit as h approaches 0 of f of h minus f of a, and maybe that's what i should have over h minus a.
01:00
So if i were to think of this as e to the h minus e to the 0, over h minus 0.
01:08
I forgot to rewrite the limit.
01:12
The function that i'm talking about is f of h is equal to e to the h.
01:23
And it's asking me to evaluate f prime of zero.
01:29
I don't know if that even makes any sense.
01:32
But the derivative of this f prime of h is e to the h.
01:39
And so if i ask you to do e to the zero power, it's equal to 1.

So there's your answer to part a...
