Please help with the following:

Determine the accuracy of the following approximation, using Taylor's Theorem. There can be more than one correct answer depending on your value for M, but use a reasonably small M.

e = 1+1+1/2!+1/3!+1/4!+1/5!

Do you know what "Taylor's theorem" is?

Yes, I need help applying it with the M value from the remainder estimation theorem.

Hi kimsanders82,

I think HallsofIvy is just trying to figure out where you're stuck, and the place to start with this problem is Taylor's theorem.

Here's what the first step looks like: You want to estimate the value of the function . Taylor's theorem gives:

where R(x)=...

If you understand how to get from the general form of Taylor's theorem to this expression, you should be able to say what R(x) is. The M comes in when you try to estimate what R(x) is (when x=1, of course).

Hope this helps.
