Question

Find the first four nonzero terms of the MacLaurin series for (e^x -x -1)/x^2

Answer 1

The answer given is: 1/2! +x/3! +x^2/4! + x^3/5!+...

Answer 2

If you look at the series the third term of the series is where that answer starts.

Answer 3

So what's the question if you have the terms?

Answer 4

its more on how do you get to the terms rather than the answer itself. I guess the question is what are the steps

Answer 5

I'm assuming you have the MacLaurin series in front of you right?

Answer 6

I just have the question itself. The terms I gave are from a separate sheet used for reference.

Answer 7

That's what it looks like.

Answer 8

yeah i have that and the equation for e^x, sin x, and cos x

Answer 9

All you have to do is take the derivative a few times and begin to plug it into the equation

Answer 10

alright, thanks!
