Let f have a power series representation, S. Suppose that f(0)=1, f’(0)=3, f’’(0)=2 and f’’’(0)=5.
a. If the above is the only information we have, to what degree
of accuracy can we estimate f(1)?
b. If, in addition to the above information, we know that S
converges on the interval [-2,2] and that |f’’’’(x)|< 11 on that
interval, then to what degree of accuracy can we estimate
f(1)?
