Please help identify equation



#4

Recently my wife gave me a gift (just because). It was wrapped in paper covered with many equations. Most of them from first year calculus and physics with a finance equation thrown in.

But, one of the equations I've seen and perhaps even used, but after a month of staring at it I have been unable to remember where I'd seen it or why I used it.

Thanks.

        oo

\ f(i)(0)
f(x) = . ------ xi
/ i!
----
i=0

#5

This is the Maclaurin series expansion for f(x).
Which is itself a Taylor series expanded about 0.

This was part of one of the first year calculus courses I took back at uni.

Yes, of course. Thanks, Paul.
