Hi,I need help! We’re doing second order approximation which is ok but to find more accurate results, we have to use MACLAURINS THEOREM, I’ve been looking at books for weeks now and can’t get a grip of it.

The question is “using Maclaurins Theorem or otherwise, obtain the power series for

e to the power of -kh

We have to show how we differentiate it for f `, f `` etc..
i.e f `=, f``=
We then have to put it into a polynominal to recheck our results,I hope this means something to someone out there!!
THANKS FOR YOUR TIME!!
