Problem 9.2.14. Show that each of the
following is a continuous function at
every point in its domain.
(a) Any polynomial.
(b) Any rational function. (A rational
function is defined to be a ratio of
polynomials.)
Cos x.
(d) The other trig functions: tan(x),
cot(x), sec(r), and csc(x).
Problem 9.2.15. What allows us to
conclude that f(x) = sin (e*) is
continuous at any point a without
referring back to the definition of
continuity?
Theorem 9.2.1 can also be used to study
the convergence of sequences. For
example, since f(x) = e® is continuous at
