(a) Prove by induction that for n ≥ 1,
f^(n) (x) = (-1)^(n-1) ((n-1)!/(1+x)^n ))
(It is not necessary here to determine the derivatives from first principles)
(b) Write down the Taylor series for f at a = 0.
(d) Use Taylor polynomial of degree 5 to give an approximation to ln?(2).
(e) Use the error term from Taylor's Theorem to show that the error in (d) is at most 1/6. (Note that this is still not a particularly good approximation.)
