Answer

Solution will be provided later

1Step 1: Lagrange form of the remainder
The Lagrange form of the remainder for the Taylor series of \(f\) centered at \(a\) is:
\(R_n(x) = \frac{f^{(n+1)}(c)}{(n+1)!}(x-a)^{n+1}\)
for some \(c\) between \(a\) and \(x\).
2Step 2: Apply to the specific function
Compute the \((n+1)\)-th derivative of the given function, find a bound for \(|f^{(n+1)}(c)|\), and write the remainder term explicitly.
