Let x > 1, f be continuous and g be a Lipschitz function with constant L
satisfying g(1) = 0 defined on the interval [1, x]. Show then that

If g(x) is continuously differentiable on the interval [1, x], then |g'(t)| < L
and it follows by integration by parts that
+ x
which implies immediately the above inequality, where F(t) =
f(s)ds. This
