1. The problem statement, all variables and given/known data Find the Taylor polynomial approximation about the point ε = 1/2 for the following function: (x^1/2)(e^-x) 3. 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!
