I assume you know what a Taylor series expansion is
:
note that the first derivative of e^-x is -e^-x and the second derivative is e^-x
:
with c = 1, the Taylor series expansion is written as
:
1/e - ((x-1)/e) + ((x-1)^2)/2e) - ((x-1)^3)/6e) + ((x-1)^4/24e) - ((x-1)^5/120e) + ((x-1)^6/720e) + O(x-1)^7)
:
note that we use O (big O notation) to remind us that our function has asymptotic behavior
:
the above expansion can be written as
:
summation of n greater than or = 0 of (((-1)^n) * (x-1)^n) / (e * n!)
