Homework Statement
Find the Taylor polynomial approximation about the point ε = 1/2 for the following function:
(x^1/2)(e^-x)
The Attempt at a Solution
I'm trying to get a taylor polynomial up to the second derivate i.e.:
P2(×) = (×^1/2)(e^-x) + (x-ε) * [(e^-x)(1-2×)/2(×^1/2)] + [[(x-ε)^2]/2!] * ?
I can't find the second derivative here it just becomes a big mess am I missing something?
Thanks any help appreciated!
