Table 11.5 asserts, without proof, that
in several cases the Taylor series for
f converges to f at the endpoints of
the interval of convergence. Proving
convergence at the endpoints generally
requires advanced techniques. It may also
be done using the following theorem:
Suppose the Taylor series for f
centered at 0 converges to f on the
interval (-R, R). If the series converges
at x = R, then it converges to lim f(x).
