Please help identify equation
Message #1 Posted by Egan Ford on 9 Sept 2008, 7:04 p.m.

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.

       /        i!

        i=0

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.
