Let f(x)=ln⁡(1+x)f(x)=\ln(1+x), expanded about a=0a=0, be used to approximate f(0.6)f(0.6) with a degree-nn polynomial. For 0≤x≤0.60\le x\le0.6, it can be shown that ∣f(n+1)(c)∣≤10 n!|f^{(n+1)}(c)|\le10\,n! for the relevant cc. Determine the smallest integer nn that guarantees the absolute error is less than 1.0×10−71.0\times10^{-7}; include a short statement verifying the bound is satisfied.
