take the derivative three times
1 + 1/2 x^2 - 1/8 x^4
ozo

Sorry, I meant
1 + 1/2 x - 1/8 x^2

Note that the link I posted contains the exact same information, so I'm wondering why you chose to not accept it ?

Infinity,
Note:  Plus signs and minus signs mean different things.
1 + 1/2 x   (one PLUS one half x, which is what you have)  is NOT the same as 1 - x/2 (one MINUS one half x)

I think you're confusing me with ozo ;)

Take a look at the link I posted - note the image you posted is the same as the one in the link heh.

However, I included the actual answer.  Which I feel is a little more respectable than slapping down a link and a wink face.  But again, yes, I did mistake you for ozo.

Oh, I wasn't trying to belittle your reply - I merely wanted to know how perdoname_'s decision was made, so I can learn and give better answers next time :)
